New Motor

[zerokool3211]

long time no talk everyone....i havent been on here in a long time....been really busy just driving my car as a daily....anyone about to be looking into a new motor......thinking really hard between a k24a2(tsx) and a k20a2 (maybe k20a..idk yet)....prolly not gonna do anything but bolt ons and is still daily driver so was thinking th k24a2 would be more fun but just wondered what everyone thought....ty in advance

You can run the A2 swap on a stock A2 ECU, the K24 will require Kpro so dont forget to take that into account, unless you plan on Kpro already and in that case it would have to be the K24A2 hands down.

[MBaG]

Anyone know who has the best k24a2 swap with a build thread on EPhatch?

[zerokool3211]

so there is no way to run a k24a2 on a stock ecu if i got the imobby unit out of the car as well


cause even with the k20a2 out of the rsx you would need the imobby unit from the rsx...lol i used to be a honda tech for 5 years and did an k20a2 swap in another ep3 for a buddy

[zerokool3211]

so i am a little rusty on all the tech for the k24a2, it is pretty much a k20a2 with 2.4 bottom end right, or does it have a lower vtec engage like our cars.....

also looking @ a k24a2 right now with 34k miles for 1900 no tranny but with ecu and harness.

[zerokool3211]

anyone else with any info?

The K24A2 has 3 lobe VTEC just like the K20A2.

That is a decent price, but you will not use the harness or the ECU, you will need Kpro and reuse the K20A3's stock harness.

I have done plenty of swaps and NEVER had to swap or pull the Immob, we either used Kpro and or had the keys resynched(same procedure as doing a ECU replacement) and doing it your way you would still have to resynch the keys to the typeS ECU after messing around with the immobi, or rekey the entire car with the RSX's locks. I am running a A2/Z3 hybrid with a A2 ECU that has Kpro, but has the immobi turned on and all that was needed was to have the Tech do the steps for a ECU replacement and then resynched the keys to that combo of ECU/KEY/Immobi

[zerokool3211]

sweet thank you for your input....so i just need the motor and another ecu to kpro

[talonXracer]

You can Kpro the stock K20A3's ECU and use that to control any Kseries engine. the only function it will not be capable of doing is the reverse lockout for the 6speed transmissions, but if you drive a LHD car and accidently throw it into reverse while banging gears you need to just pull over and throw away the keys and retire to a rocking chair on the front porch for the rest of your life.....LOL and as a BONUS you will not have to have the keys resynched at all, no messing around, entirely plug and play/tune!

[zerokool3211]

great news.....that motor was just re posted for 1700 now....really thinking about it...

[Deadphishy]

It's a worth while upgrade for sure. K24a2's are beautiful motors for a DD. the low end makes an EP feel as light as an EG.

there is the motor i am looking at

[zerokool3211]

ok starting to try to find my motor now....anyone know anyone selling a complete swap k20a2 or k24a2...everything though all acc...harness and all

[AKEP]

car-parts.com

[MadLorEP3]

great price
u should jump on it

[RHCP0801]

why are you looking for the harness? you dont need it and you can use all off the acc off of the a3. You should do some more research because it seems you dont know how or whats needed for the swap.

also make you sig smaller, i dont need to see a portrait sized picture of your car everytime you post

[zerokool3211]

trust me i know what i am looking for....i was a certified Honda tech for 7 years.......i just want everything to make it a straight up swap....i want it to go very fast when i do it....also i dont understand why i cant run the TSX ecu with the k24a2 in the car...wouldnt it be the same as using the RSX ecu with the k20a2?....

[boricua4life]

car-parts.com

THIS! you can find k24a2 for under a G... just saying

[RHCP0801]

thats great i was a honda tech for 4 years and did the tsx swap in my driveway, i know what im talking about

Just

Buy

Kpro

[zerokool3211]

found an 05 k24a2....just the long block with 200 comp on all cyl and 58k miles for 1150....then we'll say kpro for anothe 700ish...so seems gtg

kpro 700ish?

[zerokool3211]

yeah i found an eBay seller that is a hondata retailer and he will flash an ecu i send him for 700

Flash? Kpro needs a daughterboard installed. Are you sure it's kpro and not a reflash?

[zerokool3211]

its kpro...not a flash....well he says it is kpro

[zerokool3211]

does the k24z3 have traditional 3 lobe vtec?

[whatsvtec]

does the k24z3 have traditional 3 lobe vtec?

k24z3 has the exhaust manifold connected to the cylinder head if I remember correctly. The best k24 to swap would be the k24a2

[ep3jd]

Honda fail

[Andrew]

Honda fail

i was thinking this the whole time :mtongue:

but there is still a lot of in depth detail to do a swap! keep it up gents

[zerokool3211]

looking like i may be able to start getting the stuff together for my swap starting the first of the year.....what i am planning on is to first get myself either a k20a2 or a k24a2 and just do a straight swap with just kpro to start off with since it is my daily...then maybe by the middle of next year be able to start looking at putting a JRSC setup on it....prolly run about 7psi just to give it a bit more pep.....whats everyone think

[AKEP]

k24a2 + supercharger = win

[turkish]

also i dont understand why i cant run the TSX ecu with the k24a2 in the car...wouldnt it be the same as using the RSX ecu with the k20a2?....

Why can't you run a RBB tsx ecu in an ep3?

[cyllarus]

^^^ This.

I know that the question has probably been answered a 100 times, but I'm still curious.

I can understand running a RSX ecu with a k20A2 since the harness are the same. And assume that the fact that we cant run the TSX ecu is due to the harness being different?

We can run a K24A1 though... ?

What about if you "hypothetically" took the time to pull the K24A2 harness from the TSX and mate it to all the SI chassis points?

I know the answer is a 'No' on this, but I'm just trying to understand the reason behind it.

[zerokool3211]

yeah i would like to know that too......pretty sure the harness is almost identical.....so if you can run a type-s ecu on a k20a2 in an EP# you should be able to run the tsx ecu to power your k24a2....

[ep3allstar]

i doubt it guys looked many times and talk to many people last year before i did mines its a No

[AKEP]

i forget why. i think something along the lines of im guessing drive-by-wire. lol. you should be able to power a k24a2 with an a2 ecu still.

[turkish]

There you go. I knew obd2 harnesses/ecu should plug-n-play. drive-by-wire is the issue. I wish the ep had a better platform - 200hp with 6sp tranny. I can't justify pulling my k20a3 because its running strong and will probably go 300k.

[cyllarus]

Are we 100% sure its drive by wire?

That cant be ALL of it. B/c if so i could just install the k24, k24 ecu, but rig the a3 TB to mate up, and use the ep3 "wired" TB.

[AKEP]

There's an obvious difference somewhere, that, i don't know. else it would have been done many times by now. i know theres an extra box that the pedal goes to, and the ecu reads that input, and spits out back to that box to control the TB plate. which also sends data back to the ecu. theres probably a little more to it than that, but im sure the ecu would need the extra wires to run all that. the key to any swap is having a harness that is capable of supporting the engine and its needs as far as using its matching ecu. we forget that swaps can be done without hacking away at harnesses and using ecu jumper harnesses. to make it plug and play you would need the supporting systems that the ecu and motor use. i think that there is also something different about cranking settings on the drive by wire ecu's. they don't operate the same as ours either. i dont think it would start eitherway, because of that. it would def run it. i think thats why until last couple of weeks, the k24a2 ecu needed a jumper harness and kpro to run modified. it uses the stock ecu for starting and closed loop i believe, and kpro during open loop. (now they have flash pro)

but if that was more than what you asked for, you can use the ep3 tb, you just need the karcepts tb adapter. but obviously you'd need kpro to run that, because of above statement. you still need kpro regardless of flashpro availability because our cars aren't configured for drive by wire, unless you install the whole system.
