You should check out the thread on safety that David started... that might give you a clue on how things get complicatedly out of hand.

BTW, how is your 2.4, did you sort out the misfire?

Lol, that looks WAY better then my power curve to get to the same hp. See how mine looks with more compression in about 25 years when I find the time to put the motor in.

I would say my budget is 10k. Maybe a f22c with head work will have to be considered but the torque of the stroker is so appealing. Anything north of 10k I think it's time to consider a k24 like Mr Sideways, but somebody would have to offer a "kit" that's kind of turn key like they now do for the k24 Miata

This is the last "stock" 2.4 we put together. It peaks at about 7800. Revlimit is 8400.

Tom Tangs 2.4 as well

So yes..there are reliable 2.4s at the track so far.
I believe the first 2.4 blew on him very quick and didn't last him at all last season and went on a spare (stock f22) so this might be his second one, just saying...from what I have seen its really hard to have a reliable 2.4 engine that can take the abuse a stock motor can. Unless its a toda built motor. Even then that might cost your sack Lol.
Thanks for the info. Curious as to why as his build pretty replaced every part including a sleeved block.

Talking to another guy at the track a while back with a K24 integra, he said any time he rev'd his car on track above 7800rpm, his motor would eat oil. He kept it to 7800 rpm after that.

lol.

My car is at the shop for a bit. Jason (Wadzii) was able to look at my tune and mentioned part throttle was bad...he was kind enough to look it over which was very much appreciated.

I have an intake and tune setup for th 28th of July. Ill see what my new numbers are and my misfire should be resolved with a smooth tune.

I can point you in the direction to get everything done to have it bolt in with the exception of wiring harness and ECU. But WARNING, I spent $25k doing mine. But that's 3 engines, 2 headers, 2 intake manifolds and 2 sets of cams. When you get stuff wrong the first time around the price goes through the roof. I think knowing what I know now I could reproduce exactly where I'm at for $10k.

If I were to do it over again, I would buy a Civic Type R head instead of the big bad boy ported head. I would build a 12.5:1 motor. Run a Drag Cartel 3 cam and run the same intake and exhaust I have now. That would have saved a bunch of money knowing that up front. Also having the $25 plate at the front of the oil pan to stop oil from sloshing into the timing cover under braking is crucial. On just head and cams (including the ones that didn't make any power) I've spent $5k.

I think if I were reving it higher on just the setup in the car it would make close to 300whp at 9k though.

The budget on the car from the dyno graph I posted above was about $6k, for 10 we can sleeve the block, get a really nice set of custom pistons made along with a custom intake manifold and it'll last a really long time and get it close to 300hp.

the car from the Dyno graph above still had a stock ap1 throttle body, intake manifold, cams and header.

Thanks for the info. For intake manifold, does the RBC or RRC not fit? I wish I was going to Sebring this weekend to see your car. I will be up in July running my civic in FARA. Don't know if you have any interest in that group. Anyway, look forward to seeing your car develope. I have some time as my goal with the S2000 is to run it at the December Miami 500 as its first race.

If your thinking about a K24 swap then you need to start building NOW. The Header took 3 months alone. As for my car at sebring. The motor in the car has run now 3 times at no oil pressure so I'm not going to go ring the guts out of it lap after lap. I'm just going to go do shake downs in it. I'd honestly be surprised if I crank a lap sub 2:30 with how I'm planning to drive it. I've got a Z06 there to ring the guts out of.

IIRC, 20k+ so far for Mrsideways setup. f22 is where you want to be if 10k is your budget,

3k for the f22 you need
2k for ECU and tune
1k for a good radiator and oil cooler setup


Thats 6k if you can do all the labor yourself. If you cant youre close to 8k-9k.
Stock clutch works but you can upgrade (1k installed) and an ECU is not really needed for peak WHP but helps A LOT around 5.5k-6krpm for a stock 2.2

I spent a little over 11k for all my parts currently on my car. I chose to pay for the labor but could have done it myself. Would have saved 2k. I also got lucky and found a good short block and head for $1k....to find a good motor thats usable youre probably going to spend $2,500+. My 11k did not include the cost of the 2.2 in my car. Otherwise that would put me closer to 14k

My actual cost to build my 2.4
1k for used motor (3k for most used motors)
1100 for Wadziis kit
3000 for Laskey to build my motor and misc. parts I ordered. I kept stock springs/retainers/vales/cams

~5k


This stuff adds up quick and a lot of what has been said by DavidNJ is waaaay beyond your 10k budget.
