Depends on your altitude. 91 octane is acceptable for 11.5:1 at sea level and up to 12:1 at higher altitudes technically. That’s according to the math, of well what compression does 91 octane fuel detonate? Pretty high level, but, what happens when you compress a crapload of air into the cylinder with it? Well your 300cc squirt of fuel just got another 300cc of “02” in the jug with it.
Squish them together, and welll… BAM! hehe
I’m going to go medium static compression with a medium effective compression when I boost.
In order for the boost to be stabil I must not exceed an effective compression of 15:1 (I believe) oh [don’t ask me why it is 15:1 on 91 with effective compression, that I have no clue why]
So, 10.6:1 compression (give or take as decking isn’t quite the same as type-r) with a boost of
ok

Induction I’m not too sure on. Either a Skunk2 manifold with a bigger throttle body and a Password JDM Power Chamber Intake OR ITBs.
I’m still researching the ITB thing, I want this motor to still be streetable in every way shape and form.[/QUOTE]
um maybe a Christmas wish list. Do you know what you are really doing?
I’m not sure what set up I’ll run.
It’ll be surprise.
