technically, you can have a boosted high compression engine running ie. 5psi having the same power as a lower compression engine running ie 9 psi. different turbos will yield different power from different psi, a t3 60 boosted at 5psi will have different numbers than a t3/t4 boosted at 5psi.

there are other ways to lower a compression then to get lower compression pistons (which can be costly) ie change of headgasket etc

pocky man - is there a specific hp your aiming for? since the almighty H has good torque numbers i suggest a t3/t4 which is good for daily driving and minimal turbo lag that puts down good numbers. what ems/fms do you plan to use? equal length ram horn or log style manifold? its the little things that adds up that ends up hurting your wallet. but since your a balla now, it shouldn't be a problem for you

Read this about n/a cams vs turbo cams http://forums.evans-tuning.com/viewtopic.php?t=1623 I have personally seen several cars going with itr/ctr cams instead of crower/skunk2 turbo cams because the turbo cams lose hp top end. Even though they mostly talk about b series engines they mention the h22 in there. Anyone else have experience with n/a cams on a turbo engine?

"Typical turbo cams have high lift, lower duration. This doesnt work well with honda engines. They like to make peak VE at higher rpms, and using a cam like this will ultimately limit the amount of scavenging that occurs in the higher rpm level. With a high lift, low duration turbo cam you'll make alot of midrange gain, but the top end will drop off since the engine wont be able to breath through the reduction in total valve time open (duration). One customer had a set of Crower turbo cams, he lost nearly 40whp at high boost compared to a pair of OEM b16a ones. OEM gsr and itr are really good at making high rpm whp that honda engines are known for.""If you are trying to make alot of peak whp, i.e 8-10k range, the overlap will help scavenging at the higher rpms"

Thanks for all the advice, everyone.

I am purchasing a JDM H22 shortblock very soon... only 150 bucks!
