Even on 11.1 on domestics you dont need race gas. Someone can't tune/build a motor then. We have 12.5 in one 350 on pump and 14.5 in the Mach1 (race gas tho
).
A Si motor is a 1.6, thats .4 over. You wont see that on stock sleeves, maybe not even that block. Not sure though.
130-140whp? LMAO.. If you are boring that much.. depending on your entire setup.. If you get a nice cam, im, tb, etc... get everything addressed, dont have to have full race setup. Look aorund 170 or so to the wheels..
to get around 200whp, it would have taken, complete bore, resleeve, 13.1's or so, full pnp job, strip cam, etc.etc..
The d-series is a good platform, i'm not gonna knock it, but if you want to build one for the hell of it, then cool, i applaud you. If you are building on and hoping to run with the fastest on the streets. Get a b16sir1 b/c a NA d-series, will hold its own, but not against heavy modded cars, turbo cars or cars with a b-series and internals done and good tuning.
