I have 93 integra w/b16 sir2. I know the b16 has high compression. Is there anyway to drop the compression without changing the cylinders or what is the best way to drop compression without braking the bank and not losing a lot of horsepower. Also i have most the parts i need for a turbo can anyone tell me if i am missing anything.

charge Pipes
Turbo
Intercooler
Hondata
oil lines
colant lines
Bov

 

get a thick cometic head gasket to lower the c/r

 

With Hondata and a good set of 450cc injectors, I really wouldnt worry about lowering your compression, the car will be more responsive with a higher compression ratio and less boost, than a 9.1 c/r and say 3psi more.

If you had a VAFC hack and 450cc injectors w/ some tuning.. would it be ok to run around 7-8psi on a stock b16??
