First off thanks Skoundrelusa for saving the contents of the thread! This is also a good time to add a few things to the thread since I have had many questions regarding the same questions.


Here is a informative thread for anyone considering a tsx swap, and I hope it will be sticked. I went from a supercharged K20A3 to a stock 04 K24A2 engine. In doing so I had to search and read quite a few threads to find answers to my questions, hence the reason why I chose to create a summation of things I find nessecary to know.

The engine fits and no modification is necessary.

Things you will be using of the A3 are:

-Wireharness
-Throttle body
-Alternator
-Starter
-Tensioner
-Crank sensor
-Thermostat
-AC compressor ( no need to disconnect lines)

Parts you will be using of the k24 are:

-Waterpump
-Oil pump

The powersteering will be removed, since the ep has electronic powersteering.

Thats basically the list of big parts.

Other parts to use:

I used the k24 fuel rail, since the ep3 doesn't fit on the rbb manifold. However, I did use the black piece of plasting guiding the injector clips of off the k24, this way you can clip it onto the fuel rail

You will need the karcepts adapter www.karcepts.com, part number KIM01. You can then use two throttle body gaskets, I used permatex instead.

You will also need the crv bracket, replaces the existing bracket on the passengers side.

Note on the thermostat, when swapping thermostats, use the k24 metal piece, I'm sure you can use the a3 one, but I didn't feel like modifying it to make it fit.

I also had trouble fitting the throttle cable bracket, so right now its only secured by one bolt. This is because its in the way of the fuel line, since I used the k24 fuel rail. Possibly if you use the ep3 fuel rail you wont have this problem.

Since the rbb im postions the throttle body at an angle, your intake will most likely not fit. I used a injen sri 3", and have it positioned it securely using a different elbow.

I also had trouble with the throttle cables sitting to high up against the hood, causing the engine to idle at 2k rpm in my instance. I removed the insulation on the hood and it solved it.

You must remove the map sensor from the tb when using the rbb im, there is a place for it on the im itself. If you dont do this, the tb will not fit.

The stock exhaust manifold will clear the stock sway bar.

You can use your 5 speed transmission, along with the clutch and flywheel. Be sure to torque the flywheel to specs.

You will use your stock k20a3 belt, not sure of the part number. I didn't find an answer before the swap, but I had quite a few different ones laying around.

On the A3 harness, it will be obvious with sensors plug in where. The only ones you can confuse are 2 on the throttle body.

As most of you know, you cannot use the tsx ecu, or pnf ecu, you Must have kpro. In my instance, I kept my stock ecu, bought a pnd kpro'd ecu (02-04 rsx). Just in case I sell I dont have to mess with the immobilizer. Think in advance.

Other comments.

When removing the a3, I dropped it out of the bottom, with everything still attached, then swapped parts.

I had trouble taking my axles off, or intermediate shaft, so I secured them using coathangers, kind of ghetto, but it worked.

You will need a variety of hoses to cover all the vaccuum and coolent ports. Be sure to have a few extra with clamps.

Be sure to replace the oil filter if necessary before installing the engine, just makes if easier. I had to jam a long screwdriver through the filter, since it wouldn't turn.

Be sure to have a couple of jugs of coolent, a can of grease like lithium, a degreaser, and some permatex. I would also suggest to collect all metric bolts from you honda parts, in case you break or strip a bolt

Troubleshooting:

Since your draining all the radiator fluid, and air will be stuck in the lines, you must bleed the system. The way I did this is by letting the engine idle, while having the radiator cap off, preferably with while jacked up. Air will escape coolent will gush out, just make sure to add more. Also take a look at you ECT, mine was about 225F on startup, basically meaning air was still in the lines. When all air was removed it was under 200, if it makes you feel comfortable set cooling fan to come on at a lower temperature.

Another issue that I had was P0335 CRK sensor no signal, in my case, there was a bad connection between the crank sensor and the plug.

I also had trouble with the newer tsx stock basemap, which caused my VSS, AC and temperature gauge not to work. This is an easy fix. You must open kmanager and go to parameters-misc and select normal operation for multiplexer. Also make sure that "Use VTP as AC switch input" is deselected, to ensure that the compressor will work fine.




If you are coming from a cammed or I/H/E k20a3 you will definately feel the power. I even noticed a difference between the jrsc a3 and the tsx. Lots more torque and its pretty quick too. All in all well worth the money. It is a good platform to start with. Having had the jrsc for a few years, and now the k24a2, I will never go back to the A3, never say never though. Since then I have added the jrsc again and it makes a huge difference being tuned with good bolt ons.


I hope this thread is informative to anyone contemplating the tsx swap, for any questions on the swap pm me, and I will do my best to help you. Same goes for any jrsc related questions.

As for aftermarket exhaust and raceheaders, there are several different options. I have had the Jackson Racing raceheader and the Buddy Club raceheader, both fit. Since the k24 sits up higher there will be less clearance, and the header may rattle even when removing the cats heatshield. I suggest adding some esmm or some new motor mounts.

The stock swaybar will not fit, you have to use the em2 (03) I think its 15.9mm. The newer ones are a little thicker.

Answered question here Madlorglk

Permatex is a high temperature sealent, its the white stuff you see by the oil pan example. Whenever you add the karcepts adapter just add a little permatex to make a good seal, honestly no sense on wasting money on the gaskets, I actually ran without for years. You also dont need an k24 exhaust manifold gasket, just use the stock ep one.

Also it shouldn't be difficult removing the belt, use the tensioner pulley.

I actually used the info you posted above, along with davis's and other hatchers info on making a list myself

There are some parts on my list that I have questions on so I will post it up in a bit. I was gonna start my own thread but theres just too many k24a2 into ep3 threads already, so if you dont mind I'll post my list here

The reason that I was considering replacing the gaskets to the aftermarkets ones lke p2r was because I read that they help with heat transfer or insulation
Im not really sure how it works but Ive read about people who have used the hondata intake mani gasket say that not only does it add hp but you can even kiss the intake mani after running the car cuz it still wont be hot

Just the seal itself without any gaskets dont seem like a good idea to me
Im probably not understanding all this completely but is the purpose of the gasket to seal and make sure no air leaks or does it also help with insulation?

It would be nice if we can have one official k24a2 for noobs thread
where a list of parts needed would be provided ALL IN ONE PLACE
but if noobs still had questions then they can go ahead and ask

Im talkin about me of course...

MadLorEP3
04-20-2010, 01:42 AM
So for the k24a1 you have to use the a3 water pump
but for the k24a2 you have to use the k24a2 water pump

si o no???

Also what did you mean when you said k24 metal piece
with regards to the thermostat housing???

Yes using 'plastic' gaskets helps with heat transfer.I had the hondata img and it really made no difference for me. I used it in between the jrsc and the head. The goal is to reduce the intake temps. And again anything will help, but will you notice any difference? No.

The belt I would just go to the local autoparts store, and say you need a belt for an ep, they will give you the right size.

I would stick witht he oem crv bracket. Not sure what benefit the other has.

Dont forget you will also need new bushing to use for the sway.

Also I wouldn't go with a prb ecu, unless you have a six speed tranny. Pnd or pnf are cheapest wat to go.

As for fluids, that is more of a personal choice to me. And the hondabond is actually good, no need to get permatex then.

Midpipe, forget the sizes, but I think that the newer type s, 05 06, actually are a hair larger in diameter.

I did use the k24a2 waterpump after pulling it appart, but mainly because I didn't feel like taking the one of the a3. The metal piece, coolent housing, I used it from the k24a2 because of fitment, but used the ep3 thermostat.

thanks for the info bro
yeah I didnt include it in the list but I also have a bunch of upgrades that Im doing to the tranny and a tsx 6 spd is one of them, along with LSD,
and still not sure about a 4.3 FD??? stg II clutch &11.5lb flywheel

ok I will add the bushing for the sway

What I dont get is y I will be using a belt for the ep when my motor is k24
to be honest I dont even know what the belt attaches to
is one of them the crank pulley?

ok no permatex, had the hondabond for my bike, its still full

I know that 05-06 type s midpipe is larger but thats just an upgrade right
I mean the 02 type s midpipe that ihave should bolt up just fine to my type s dcrh

got it ep3 thermostat with k24 coolant housing, and either k24 or ep waterpump

thanks bud

The k24 crank pulley and ep3 are the same I believe and yes the belt goes around around the cp, plus you dont have the powersteering pump and using the ep automatic tensioner. The backside, flush side, of the belt will always touch the smooth pulleys.

Yes the 02 midpipe should bolt right up.

Ive been looking at the part numbers for the em2 front sway
em2 refers to 01-05 civic coupe ex right?

01-02 civic ex coupe 51300-S5D-A01
03-05 civic ex coupe 51300-S5D-A02

I know that Im looking for the 15.9mm front sway but I wonder which one of these 2 it is? the bushings have different part numbers as well so Im assuming there are 2 diff sizes

vbpracer
04-20-2010, 02:49 PM
Its the earlier one, I can verify the part number tonight for you if necessary.

04-20-2010, 03:19 PM

ok so 01-02
this might be it since I know that

well club rsx lists the part 51300-S5D-A01
and describes it as being 25mm

that would be great if you can verify part number later

i just got an em2 sway bar off a 4 door civic, and it did NOT fit. i have a DCRH with a k24, if i want to install that sway bar, it will hit a few hoses up there, or cables im not sure what they are, maybe a/c lines.

em2's are not 4 doors, em2's are coupes and you need 01-03 sway bar....not 04-05

vbpracer
09-09-2010, 08:37 PM
You have to use the em2 (01-03) I think its 15.9mm. The newer ones are a little thicker.

btf144
09-11-2010, 09:21 PM
i thought it was the other way around. there is much confusion around regarding these sway bars. Some people say that the newer ones are 15.9mm, while the older ones were 24.5mm. anyways, sorry for the newbieness, but from where to where is this length measured? one of the em2 sway bars will not fit, it sits too high up the chassis and is in slight contact with a few stuff. would that one be the 24 or 15mm?

vbpracer
09-12-2010, 10:24 AM
Let me put it to you like this, I am using the 15mm Diameter one, its thinner, with a bcrh and k24a2, and it fits no problem. You do NOT want the thicker one.

btf144
09-12-2010, 04:50 PM
thanks a million. i was hoping it was the 24mm one that didn't fit. i think my car understeers as is.

09-12-2010, 09:05 PM
Yeah, to tell you the truth, I didn't run a sway for several months, then got around installing it, never even noticed it. I dont track my car however.

09-14-2010, 06:45 AM
I just ran into this same problem on my ep while running an obx rsx-s spec raceheader but no swap. The part number you need is 51300-S5D-A02. It is the 15.9mm bar I can attest to that. While I was at it I picked up energy suspension bushings to go with it. Anything you want to know about swaybars is in this link in the suspension section http://www.ephatch.com/forum/showthread.php?t=43253

I hadnt had time to reply to your pm. I think you asked me about the map sensor? The sensor will be located on the rbb manifold itself. If you don't have the motor already, you will see, its very obvious. I dont think I have a pic without having the jrsc on there, sorry.

i would also like to add if you are still using the ep3 trans on the k24a2 and your check engine light is on and the code is for the vehicle speed sensor. Go into your parameters and select misc, uncheck the 2 boxes under speed sensor, go into the gear comp tab and click select ratios, in the dropdown box select ep3 civic si than upload it...should work perfect as it did for me. Got this info from k20a.org as i was just about to buy a new sensor

you cant run a different engine off an ecu made for an entirely different car. I think people have gotten the car to start but it ran like shit and your risking damage to the motor by not having it tuned right

vbpracer
12-16-2010, 12:40 PM
There are many different reasons why you cannot use the pnf ecu, cam timing, compressions, harness etc. To use the k24a2, you HAVE to have kpro.

I have an 07 tsx motor
N I also got the karcepts adapter that was mentioned here
My problem is that on an 07 rbb there is no idler control port
But there is one on the karcepts adapter
So now I have no idle and I have to step on gas when I'm at a stop sign so car won't shut off
Also my aem v2 intake won't fit properly
Any suggestions for these 2 issues
Not sure if I'm making sense

I will be looking for an rbc asap so I can reuse my aem v2 intake....

talonXracer
12-31-2010, 07:55 AM
There is a fairly easy fix for the lack of a IAC port in the mani. A 45 degree angle cut needs to be made in the Karcepts adaptor and a corresponding cut made in the mani's flange to create the port. This can be done with a dremel or a right angle grinder or a machine shop can do it for $$$

I have done it for several guys already with RRC mani's.

RHCP0801
12-31-2010, 09:51 AM
thats weird the v2 doesnt fit, does it hit the hood? might need a 45 degree elbow or something like that....oh and the rbc will reduce your tq, i would just look for an 04-05 rbb mani instead of the rbc

rbc also requires massive amounts of cutting to the rad support

people say the tq loss is noticeable, look on k20a.org and there is a lot of info about it. Your probably gonna lose about 10ft/lbs of tq and maybe gain 1 or 2 hp. I was gonna change to an rbc until i read that so im sticking with the rbb

here is some pics of the rbc not on the k24 and you can see the cuts, the k24a2 sits higher and the intake mani design is different so your gonna have to do more

You will gain far more than 1-2 whp up top, try adding a zero to those figures. but there will be losses down low, on a FWD car with tons of torque you will merely produce profit for the tire companies.... LOL


The RBC in a EP3 with a K24 doesnt require the "Trimming" that the shorter K20 requires.

But no matter which engine, it is NOT the major surgery as some would try to make it out to be.....

And yes that DIY is exactly what I described,

RHCP0801
12-31-2010, 06:28 PM
there is a lot of mis information going on about this, i never saw a dyno where the rbc gave 10+ hp over the rbb

edit, just saw a dyno posted where someone gained 19hp, from the prb mani with the rbc but did lose low to mid

The rrc manifold seems to be the best out of all of them but also the most expensive

tnx for all the info guys
swap is finally in and done
Unfortunately I drove her in the freeway to go home but stayed at around 65mph without programming my kpro
She is still set at my stock k20a3 with minor bolt ons setting
She ran like shit, felt weak, and idle felt very low (not sure if Im using the correct terms to describe it)
I just downloaded hondata program and I know she will drive better then

I ended using the rbc and did some shaving of the metal part sticking out close to the karcepts adapter
I was in a rush today so decided not to mod the rbb for now
I still have it though if I decide to do it later
aem v2 fits fine with the rbc...tnx for all the info

on Kmanager the only thing I could find was a k24a2 310 injectors...is this the best setting for stock 07 tsx with I/race Headers/E

not the manifold. you can either buy the special gasket which takes care of the problem, or you just run a tap through the coolant port on the block to thread it, then screw in a fitting. sounds much more difficult than it is.

She's running a lot better now that I chose the own k24 setting on kpro.
Not completely satisfied with the gains but I will wait till I get a tune to see if I will be happy wid this swap. Probably need to surcharge her in the summer.

talonXracer
01-01-2011, 06:55 AM
The problem with using the A3's calibration is Kpro being engaged well before 4K, uber lean. Limited running should be ok,

And as far as dyno's showing the significant gains of the RBC over the RBB on the top end, there has to be thousands of them, every RBC swap produces a minimum of 15whp more on the top end. Throw in a set of cams and the RBB just needs to slither home with it's tail between it's legs.

But does this mean I recommend the RBC over all others? NOPE, I would opt for the PRC/PRB mani's. The PRC will show the 1-2 whp loss on the topend in comparison to the RBC, but will show significant gains in the midrange. The K24A2 is a midrange engine, the torque monster of the Kseries.

i sent an email to jeff evans who tuned my car about this while intake mani situation and this is what he said, ill take his word over anyone on the forums

From the experience I had with several customers doing honda challenge road race series with k24a2 engines without doing cams, 50 VTC gear, etc, the stock intake manifold worked the best. The longer runner RBB manifold works better for the 25 degree VTC gear from what I have seen. This is with stock cams as well.

Thanks!

^^ This is the conclusion I have also reached. I bought a PRC to replace the RBB but could not find any dyno's that showed hp or torque gains. The RBC makes more hp but gives up way too much torque.

For now, the RBB is the way to go for me..

Sure the RBB is decent as J Evans stated, but as soon as the VTC is swapped out for a proper one, the RBB falls on it's face on the K24A2. And as for the K24A1/A4 goes the RBB and PRB manis are optimum with simple bolt-ons.

I have seen a PRB mani with a plenum extension show gains over the ENTIRE rev-band on a 08' K24a2 w 45 degree VTC

Seems pretty clear to me to use the KIM06. Exterior shape and size seems to be very close to the same. Still depends on who you ask. I did a K24A2 + RBC swap and didn't cut the support at all, I just took a rubber mallet to it and bent it under/back a tiny bit. Just get the motor in and check how the clearance is.

PRB mani and EP3 TB on a K24A2 head will not work with AN fittings, the throttle body is too close to the head.

all that hard work for nothing.

also, theres a sensor in the front by the starter, im guessing is ECT or something, its plug is different than an RBB-2's similar sensor. the connections aren't even close.pics later.

PRB mani and EP3 TB on a K24A2 head will not work with AN fittings, the throttle body is too close to the head.

Alright cool. Just asking. Why shouldn't I use the type s tranny?

i have the type s tranny on my a3 and obviously keeping it when i put the k24a2 in. But its a huge difference in the gearing from the 5 speed. if u have the extra i'd spring and get the 6 speed if ur staying all motor

Yes you will need the karcepts adapter to put the skunk2 or ep3 throttle body on. The Ep injectors are way to small for the k24a2, they are only 270cc and the k24a2 stock are 310cc. Let me know if you need some I have tsx injectors for sale.

a cold air intake wont fit with the stock rbb manifold, only certain short rams do. You have to custom make a cold air if you keep the rbb which is good idea unless your boosting or doing cams down the road in which in that case you should get the rrc mani

my header also cleared the front sway bar, only thing is it hit the body but an exhaust shop fixed that quick

oh yeah, i should have also mentioned that its all the same fit if you use the PRB/C manifold. i keep forgetting you guys are also talking about with the RBB.

Just for refference i ended up tapping the coolant port for 3/8-18 NPT and sticking a 3/8-18 NPT-10AN reducer and a 10AN 90 degree barbed fitting and it didn't fit under the PRB manifold, so i got a 3/8-18 NPT 90* barbed fitting. clears all day.

The reason I chose an NPT fitting over AN fitting is because NPT seals with the threads, as they are tapered. AN fittings seal at the flares. There is no flare inside the coolant port.

For anyone who has done a k24a2 swap what did you do to make the EP harness work/fit? I have tried to get mine to fit and I can't see how it can be done without adding length to some of the wires. I can get it all hooked up but alot of the wires are pulled pretty tight and looks like shit running over the top of the water port on the drivers side of the head. Just looking for some input before I start chopping up my EP harness to make a custom one. Ephatch really needs a wiring section. Any pics of how you ran the harness would be appreciated. Thanks.

Are you sure you have routed correctly and its not caught on anything, everything on my swap plugged in perfect with no problems

japarossa
04-27-2011, 01:09 PM
I run into problems right away, if I put it on top of the water outlet my wires to the transmission are to short or very tight. If I put it under then the wires going to the coils and vtec solenoid are to short. The connections are in the same place but the ep doesnt have the water ports on the side of the head and thats what is getting in the way. Even the wires going to the TB, fuel injectors and the plug that plugs into the other harness under the intake manifold are giving me problems. I am also using the RBB TSX manifold so that does make the connections a bit different than on the ep. Like I said I can get it on and all the wires hooked up but alot of the wires are tight to tight. If anyone has a pic of the drives side of your motor with the harness please post up a pic so I can see how you ran it.

Which gasket do I use from hondata for the IM to TB adapter?

What is the point of this?

"Note on the thermostat, when swapping thermostats, use the k24 metal piece, I'm sure you can use the a3 one, but I didn't feel like modifying it to make it fit."

Are people using the A3 thermostat?

Pretty much if anyone has a list of essentials that are needed for the swap other than the obvious kpro, crv bracket, and patience?

When swapping the k24a1, is it the exact same as the k24a2?

basically. the k24a1 is actually easier i think because the intake mani isn't all tweaked out like the a2 one is. either that or it's just easier to swap the k20a2 mani onto the k24a1 than it is to swap it onto the k24a2.

the intake mani and the passenger side bracket are really the only changes from the A3 unless you're doing a race header, in which case you might have problems with it hitting the sway bar

K24a2, Type-s or aftermarket valve springs, Type-s oil pump, Type-s vtc solenoid and actuator. Cams are no need to change, depending on the build, that statement could be extremely false. But that set up will take a K24a2 to around 8600rpm safely while still making power.

I'm not sure 8600 is considered safe. Those are extreme piston speeds at that RPM.

Wouldn't recommend driving for long at that rpm, but it will allow the k24a2 to rev like a k20 with no contact. That's the safe part, and if going stock, is a better route than a frank.

I have read this thread through its entirety and I still need some clarifications. Here is what I have:

TSX complete longblock with engine harness and all that....it was given to me for doing a swap. I think it was a good trade since he was broke.

I need to know if I can swap the intake manifold from the a3 to the a2. There is some information out there that says you cannot swap this over but there is also some info that you can?

If I cant use the a3 ntake manifold is the only option to buy the adapter for using the a3 throttle body? Or will a different Intake Manifold be more suitable? What is the best suited for the k24a2 or do you have to stay OEM on this one. Mine is an 05 raa motor if that helps?

Thanks for the input here. I am new to K series but NOT new to swapping engines in between chassis.

you can use your a3 manifold.

RHCP0801
09-22-2011, 08:15 PM
if your going to fully build the motor and boost it, get the rrc manifold which costs a bit over $300 new. If your just doing bolt ons get the rbc manifold from the 06+ si. People are selling those all of the time for around $150. You can use the ep3 intake manifold on the motor. If you get the rrc or rbc you will need the karcepts adapter to bolt on the ep3 throttle body

AKEP
09-22-2011, 10:40 PM
you need that $90 adapter plate for the ep3 intake mani to work on the k24a2, because of that coolant port.

otherwise, you can spend about $20 on an NPT tap and a *90 npt-barb fitting to stick in the hole.

one way or another.

if you want to use a hondata IMG, you need to get the one that matches your intake manifold.

He said the head/ trans, rack and there is a block there but not sure if the block matches the head. He was cleaning out a storage facility for a friend and the guy told him to take it.

I think my time there was pretty good considering I have never done a k swap. I kept his K24a2 for my ep3. So I need the timing chain, tensioner and so on for getting it ready for my car.

Well he did not have any money to pay me. Normally I charge half of shop prices to install. I go a little above and beyond on my installs too. I also take trades depending on the swap and so forth. I have ended up with chasis before too. I just like doing swaps really. I am trying to decide on if I should keep this thing or sell it and get a k20a2 or a k24a1. I am seriously not ok with dropping a G on a freaking ecu. I cant believe that the K series ecu has not been cracked by anyone other than hondata. That price point is absolutely insane. Then to have to pay a shop to tune on top of that is insanity. I just cant justify 800-1000 for an ecu then another 200-500 for tune time at a shop.... LAME. So I may sell the k24a2 or trade it for a k20a2 with stock ecu or k24a1/4/8 just so I can get the torque and possibly have enough left for a kpro and do vtec killer.

Does it take a long time? I kinda get worried when the temp gets 224-227 and shut it off and coolant goes everywhere.

The engine that I'm getting doesn't come with the k24a2 thermostat housing. What modifications with my k20a3 thermostat housing will I have to do to make it work?

#2
I have the k20a3 fuel rail, and the TSX injectors with the RBC IM. It's a k24a2 block, and a k20z3 head. Nothing will need modified, right? (Yes, I have Karcepts)

Alright I'm bout to buy a 04 k24a2 short block that have darton sleeves and I'm getting a 05 k24a2 head to make it complete. I read up that its not safe to rev a k24 above 8500.. It shouldn't be a problem since I have the sleeves huh? I'm planning on getting a k20a2 oil pump for the higher revs also.. if I rev to 9 than that will be bad Ass.

Heads up, everything else is stock. Might knife edge the crank and 50 degree vtc.

K20 oil pump won't support 9000rpm. Most k24a2's will stop making power in the 8600rpm range anyways unless you have a head built to flow like mad.

What's the opinion of this group as far as intake manifolds, throttle bodies, and VTC gearing for NA swaps?? I am currently using the RBB and EP3 throttle body, and a stock TSX VTC gear. I'll be swapping to the EP3's 50*VTC soon, and read the RBB doesn't really take advantage of the advanced timing....so then I got to thinking about going RBC(Though i'd hate to cut anything in the engine bay to make it fit...), and then people suggested a bigger TB to match the RBC.

if your staying NA the RBC is a good add on. Either use the stock EP throttle body with the adapter or you could upgrade to a larger one- your call. if your a bit more budget minded a max bored TB with matching RBC would be a good route too. cutting to fit the RBC is really not that big a deal. the 50deg VTC will work wonders with your mid range torque though- and the RBC will improve your top end power. check out K20a.org for more engine related specs- they have done it all over there.

Yea, I'm looking at the RBC matched to a maxbore TB...In this case, would any k-series TB work? The cheapest one would probably be the best bet...
If I had had the foresight, I would have just bought the friggin 70mm karcepts adapter for the same price as the one I bought! ...now I'll have to have that matched, or do it myself if I go down this road...

i have the rbb mani and when i use my stock throttle body the cables are touching the hood. i heard of people trimming the hood protector stuff to get it to fit. is this correct? what else could i do if this does not solve my problem?

I had the same problem, I just removed my insulation from the hood completely and its been like that for a year with no problems. The cruise control cable is bending a little more then the throttle cable, but it still works fine.

I had to remove the liner because the jrsc was rubbing with the k24a2. Happy to see this thread still going.

the starter will work with any car regardless. However, the newer starters with the internal solenoid are much better units.
