So blah blah blah Im doing darton dry sleeves in my AP1 due to low compression. I currently had the stock F20c with a p-tuning 30r that made 424 on pump gas and 507 on race gas. But time to upgradeeee. The new setup will have a Forced Performance HTA3586R turbo, intank double pumper and the built motor. Since I do not have E85 available and refuse to use pump I have to come up with another solution how to make my 500whp goal on 93 octane. I know it would easily be possible if I went to 9.0:1 compression but I feel like part of the s2000`s heart is the high compression. So I think 10.0:1 compression would be the perfect balance of keeping the compression up high engough to perform well but low engough to make 500hp on 93octane.

Anyways when it comes to pistons and rods im clueless. What would you guys suggest for a good middle of the range affordable solution? Initially the car will be making 500hp on pump gas and hopefully have a 650-700hp race fuel map. Ideally I would like to have a motor and internals that can support over 800 just to be safe.

Thanks guys and girls

if you are on pump gas you want low compression, if its tuned right you wont notice any difference driving the car.

You can not reliably do 500hp at 10:1 compression.. dont care what anyone says, it will blow.

Wiseco pistons and Brian Crower rods will serve you fine.

PM me for a good price

fullblown headstuds problem solved with 10:1 on pump gas. i know a couple of cars running this that have been together for several years. lol

I have Darton Dry sleeves with 9:1 compression CP Pistons and Brian Cower rods. I can't tell the difference between 11:1 compression and 9:1 compression its all the same. The turbo will make up for that down low power anyways. I suggest going with 9:1 for that added reliability

I've always been a Wiseco piston fan. I've used them in past turbo cars with superb results. Wiseco makes an excellent product at a very competitive price. These guys really do understand pistons and to top it off, they also include very high quality rings and pins with most sets. As you know, any piston must be properly chosen and proper clearances set. And, you can't expect even the worlds best pistons to hold up to massive detonation.

Headstuds didnt solve any problem, they cover up the problem that 10:1 is too high and 500hp is too much for pump gas.

send the block to Inlinepro, have Jeremy build you the same block I just got. its a 2.4l which uses a K24 crank and do Inlinepro rods and CP pistons. Its low compression but the car is unreal how it feels. Feels so much better even out of boost. You will make your 500whp goal and you dont sacrifice anything for being low compression.

10:1 is too high for pump gas or too high in general for FI setup?

For pump gas..

Its a little more complex than that simple answer. If you want 300-350 HP then 10:1 or 11:1 is fine. If you want more then the compression needs to be lower. Lower gives you more room for error and on pump gas you need all you can get

How is 9.6:1 on pump ?
