Hi guys i am noob and this might sound funny to you but can any one please explian how to we increase or decrease the compression on a FD3S or is there no way for that to do.....the reason i am asking this question is cause on a piston engine to run more boost we can lower the compression what do we do here and what are the stock boost limits for a stock motor with ECU, FMI, Fuel..... it would really be helpful if you can shed some light on this...





best regards

Rebuild the engine and swap in 87-88 T2 engine rotors, must also swap front and rear counterweights unless you're going to have your assembly balanced.

You would have to change out the rotors for non-turbo rotors to get more compression.

THat chart is missing the RX-8 rotors, which are the highest compression of them all at 10:1.
