here is the setup:
B18c5
CTR std pistons
stock R rods
S2S2 cams
Toda Cam gears
Toda belt
Mugen Headgasket
92 GSR head
S2 Ti retainers and springs
Hondata S200
everything else is stock 2001 ITR
Should I have any troubles on 93 octane gas for an everyday street car? Also anyone wanna help me out on a pretty acurate compression ratio? ( what CR I will have)

 

That set up is going to probably yeild higher than 13.1.

I'm not sure if 93 will suffice.

I have a similar set up (b18c5,std ctr, s2s2, oem hgasket, stock head) on 91 ocatane Im at 15 deg. ig. timing.

 

b17 gsr head tho not the 94+...still a Pr3...im thinking like 12.3-12.4
