is this a street driven car? cuz you'll have some trouble passing smog w/ race gas

 

most likely if I actually build it no wont be street. but if it were id say between 11.1:1-11.5:1

 

I built a d series motor that was in the region of 12.75:1 and ran it on pump gas with no probs. I manualy retarded the timing about 5 degrees though, and ran 93 octane on a stock pg7 ecu. Never had any problem with detonation, and for a mini-me, it hauled some serious ***.
