Default fuel system and E85 ?

i have done some research on this and have not found what i'm looking for.

i would like to do E85 and a 100 shot of N2O. what size injectors do i need and what fuel pump do i need. And any thing else?

also is there a good wet kit for the N2O. i also need a TB, any suggestions.

the car should be just under 400 rwhp off the N2O may be 500 on the N20.

specs are 94 lt1 .20 over decked, stock heads cleaned up with 1.6 exhaust valves and milled, thinner head gasket, arp rod bolts and main bolts. hot cam kit, pacesetters long tubes, ory, ect.

42 lbs injectors and dual walbros will do what you need. In the process of swapping to this myself...

Sorry to hijack but what gains would a NA car see running E85 over gas?

I was told that by switching to E85 (on my setup) that gains of 20-30HP could be had.

It's more consistent too, if you're into bracket racing.

You can tune for more throttle response, tq, etc.

It's a great fuel if its' readily available to you.

i don't really see the point if you're running a stockish compression motor. the gains won't be too substantial for the cash outlay (pumps, injectors, retuning, etc). Running alcohol your tuning window broadens, which helps the carb guys more than us. Basically there might not be much power difference in 3 or 4 points of A/F ratio. Not saying you can get by with shitty tuning, but the car won't be as sensitive to weather changes, especially IAT since the fuel will cool the intake charge somewhat.
