high compression K24

[kon]

Less then a week left before I pick her back up from the shop. The EP is getting a K24 with:
12.5 CP's
IB Rods
Balanced and polished Crank

All the supporting mods are the same as before:

CAI
bdl 70 tb
RBC
BCRH
75mm ex
Kpro

Head has skunk2 stage 2 cams
all required valvetrain and more :mwink:

Last note, as the motor was being timed we realized that the tensioner was done for. I love the guys at skunk2, some of the best people to deal with, but if I can't resolve this issue...IPS? lol hope not for wallet's sake!!

Do iiiiit..my build fell through so make me feel better and show me a dyno sheet lol.

[talonXracer]

I would NEVER risk the health of a brand new build such as the one you have, to a set of cams that are proven to destroy engines. I would use a set of OEM cams untill you can get something other than the Skunk2's.

I'm gonna agree.... Skunk2 cams blow up setups. Atleast go brian crower. Those I'm in love with. Altho you miiiiite be ok with the 2. Stage 3 will blow ur motor in a month.

[ALL MotoR Ep3]

Bump for my boy Kon......ya shyt is gonna run hard........

[davisj3537]

How big is 75mm in inches? Go Kon! I have to agree with the guys about skunk2...:der: I don't have their problem with them but if you are going all out on a build then go all out on some cams too.

[kprocivic]

hmm i still trust skunk2 a3 cams.

[Heitzke]

75mm ~ 2.95in. I can't speak from experience, but I would tend to a agree with these folks and drop the Skunk2's for a while.

[davisj3537]

3 inch exhaust eh? Are you looking to make close to 300whp kon?

[kon]

ok, now I feel like an idiot. Its a 70mm ex...lol. I wrote the original post trying to rush out of the office and accidentally typed 75...lol. Its cool though...I'm a noob...only 3 posts.

[kon]

3 inch exhaust eh? Are you looking to make close to 300whp kon?

nah...maybe 260...I'm trying though. I'm looking at investing in some IPS K2's, either that or BP's. I appreciate the positive feedback though guys!!!

[davisj3537]

The closer to 300 you get the more you are going to need a 3inch exhaust for optimum power.

[talonXracer]

When you hit around 240-250 a 2.5" exhaust will start holding you back. 250-290 will see decent flow with a 2.75" or 70mm. But remember these are just basic guidelines. If you are only concerned with topend power then go with the largest dia. pipe you can install(and that your ears can stand). If your car is a DD, then 2.5"-2.75" should be as large as you go, otherwise throttle response and low/mid range power will suffer greatly.

Aint that the truth. 70mm is too large for my liking as it is. I was running the full 70mm skunk2 ex but couldn't handle the droning at low rpm's so I threw on the old WSII axleback...nice and quite (restrictive, but quite). I would rather loose a few hp then go deaf and rack up hundreds of $ in exhaust tickets.

[kon]

Well, no more skunk2 cams. I'm sad to see them go but the K2's should do the job :mangel:

[clizoman]

nice..

[Kerby]

kon: what head are you using?

does IPS or BP have cams for the a1 or a3 head?

[shadowmd]

bump for KON....pm chunky about his tensioner....he has a custom one he has designed and has been selling and using on his built beast. he has skunk2 stage II cams and NO issues what-so-ever. he is makin around 240whp n/a on a 2.0L

I was using his tensioner for about 3K miles before I realized the failure...lol. Its a good design and I actually spoke to him on Tuesday about it. There is no guarantee that it will work 100%, however, and I'm done playing the fix it games...you know. Honestly, I love skunk2, they make great power and unbeatable customer service, but I can't afford anymore down time or repair costs. I had an oppertunity to get K2's for a good price and I jumped on it. At least now, my worries are minimal.

Plus, when using skunk2 cams, chunky recomended to retard the part throttle map to 0 advance. This almost defeats the purpose of having cams.

[kon]

kon: what head are you using?

does IPS or BP have cams for the a1 or a3 head?

Not to my knowledge. The only companies that make cams for the A3 style head are skunk2, crower (I believe). I've been out of that game for a while though so maybe someone else can enlighten us.

[kon]

quick update: its done!!! We got the block together and swapped it back into the ep3. She turned over and from what I understand, she sounds good. Time to go break in the motor and do a little street tuning :mtongue: Assuming all goes well, we'll have some dyno numbers tomorrow. Stay tuned.

On a side note, I bought a replacement clutch disk (exedy stage 2 disc) but the old one was barely used. I drove the car for a whole year, and I was not easy on her, and there's still another 2 years left from my calculations. Looks like I got a spare disk.

[clujalolo]

this is the EXACT build im planning on doing. im looking for a k24a1 shortblock right now. Hopefully start the build in the summer. :mbiggrin:

Get some vids up of interior and outside. I wanna see this thing perform

[ALL MotoR Ep3]

I Cant Wait to See Those Numbers Kon..............

[kon]

Its finally tuned. I'll have the dyno graph posted as soon as I install stupid scan tools on my PC. The peak numbers are 250whp and 195wtq, we had to retard timing for safety so the last run is a little short. I'm very happy with the results though...much better powerband then before. Now to fix the FUCKIN OIL LEAK!!!!!

[Lucid Moments]

Very Nice:mtongue:

Great number for being on the BCRH. I bet it hauuuls.:mbiggrin:

[nightrider2002]

Great numbers! I find it interesting that even built with cams the K24 still drops off in torque at 6k due to the stroke of the motor. Not that it really matters though since it makes more torque everywhere, and where the torque drops off it's about the same as a K20 at peak.

The power drops off so much on my graph due to the 60mm WSII axleback pipe. It really chockes the shit out of the motor. I have to do something about that.

thanks bro...just as a comparison, a boosted K20a2 RSX put down 244whp with a gredy kit at 9 psi (I believe). I think this dyno is a bit on the low side as far as readings go.

Damn you should be excited....because your making higher numbers then forced induction cars.......hahahahaha N/A all day....it gets no better especially with instant throttle instead of lagging and waiting for the turbo to spool up......but dont get me wrong turbo is definitely a great thing to have but i rather make power naturally......BUMP ttt for KON for making great numbers...

[talonXracer]

Some nice numbers!

Best part is that you do not have to hammer it hard to have a interesting and fun ride!

[clujalolo]

nice numbers. sounds like a beast. how does she feel.

get some vids up asap. :mtongue: I wanna see this thing in action.

True...I would like to drive it though. The oil pan needed to be resealed so hopefully that takes care of the leak. Time to start researching axlebacks that flow and don't kill my hearing.

[Deadphishy]

I think im going to get a 3 inch vibrant metal core highflow cat and tapper it down to run through a 2.5in exhuast with a small vibrant resonator and a twin loop muffler. should flow decent and not be to loud.

Finally got her back and she feels great. I don't know if it was me driving the rental Chevy Aveo for 2 weeks or if the power is really that good but the car pulls HARD!

I really feel like shit because I was in Chicago 2 weeks ago and I didn't even think about getting your number to meet up.

I'm a dumbass.

On another note, those are some good numbers, are you really reving it that high? Dangerous piston speeds at those revs.

dangerous, maybe...foolish, probably...fun, MOST DEFINATELY!! LOL I used to rev the stock K24 block to about 8000K-8100K for over a year almost on a daily basis and no problems, this one should take 8500K (although I only plan on reving that high in certain scenarios).

No issues what so ever. Running very strong even after all the abuse I put on her. I've even gone to the southside a few times to see how she holds up :mconfused:

[Lucid Moments]

Did you ever get a dyno sheet scanned in? I'd love to see it.

[kon]

Here it is. This is after we retarded 2 degrees for safety. I think the final numbers were closer to 25Xwhp and 195wtq...

[Deadphishy]

your going to have to let us know what it's pulling in the 1/4.

Put down some good numbers man.

Did you have any valve-piston clearance problems with the CP pistons and the k2 cams?
What degree VTC did you allow it to go to?
are you still using an A2 VTC gear?.
What size head gasket?

[frm_808]

ya man 1/4 mile times would be nice. debating betweent na or boost the k24 frank. if na puts a good enough time for me then thats my route

No clearance issues at 50* full advance at high cam with the K2's.
Stock headgasket.
No times yet...soon though.

Thanks guys

Very nice. I think i'll be ok then with my 11.5/1 cp pistons. and stock a2 valve train.

[kon]

Very nice. I think i'll be ok then with my 11.5/1 cp pistons. and stock a2 valve train.

You'll be fine. CP's have some of the deeper valve reliefs (when compared to shelf wiseco's and others). I think even KME's would have cleared this motor. We clayed skunk2 stage 2's and there was more then enough room at 50*, those cams are more agressive then the K2's I believe.

[Heitzke]

Just curious, but which K24 block and crank are you using for your build?

You are correct sir. I used to have a K24a4 crank and spun that thing to 8K all day.

yeah im spinning my k24a4 crank to 8200....:)

You people are crazy.

Mine won't see 8k

[Lucid Moments]

You people are crazy.

Mine won't see 8k

Then you are potentially loosing power. Mine saw 8500 on a pretty regular basis and was fine until it ate a foreign object. It was still fine except for the damage done to the piston and combustion chamber done by the foreign object. No excess wear to the rods or bearings.

My exhaust won't support making power up there. DCRH with a 2.25 mid-pipe and stock axle back.

you need to upgrade! i'm on the same boat. i just finished putting cams on the car but the dc race header and the spoon midpipe + axle back are going to hold me back.

i'm going to save up for an ssr or hytech race header and getting a custom 3 inch exhaust made of aluminum.

[Lucid Moments]

Ah, that I understand. If it won't make power then you're right, no point in spinning it up that high.

I don't know if I agree. I have a 3" and while it does make power it is so damn loud it drives me crazy. Also it hangs down low enough that clearance is an issue too. My car is a track bitch only pretty much so I can live with that, but I would not bother with it on a daily driver.

what would be the best head swap for my A3 block with some mods

[frm_808]

best head? just do a swap

[kon]

what would be the best head swap for my A3 block with some mods

if you are really set on a head swap...I would try and source a K24a1 head and swap that on with some A3 aftermarket cams (even though the ultimate cost would be the same as a A2 head). People have been seeing some decent gains with that.

[15000rpms]

did you port and polish your head? I heard that it might be necessary to do so to support higher compression, meaning that you need it to see some gains with the high compression pistons.

sure your piston didnt just crack and a peice of it did the damage at 8500?

[Lucid Moments]

sure your piston didnt just crack and a peice of it did the damage at 8500?

Yea, I'm sure. The spark plug actually cracked and dropped the electrode into the piston. The piston was whole with a bunch of dimples all over the face of it. :mredface:

[pjnoto]

ouch that sucks. what are the odds of that haha. well now its an excuse to make her that much sicker!

[kon]

Thats not completely true. You can realize good gains with the stock A2 head, just throw in some cams. I do have a slight port and polish job done to my head though :mwink:
