Do you have a 420a, and if so what kind of build?

 

[daveeclipse99]

How much boost are you going to be running and how much power are you shooting for?

We need some more info please. Like what are your goals? 300-400hp? Boost level?

Just get some 1050ccs or 1100ccs and be done. Lol, just throwing some numbers out there. We need some more info.

Depending on what your using to tune, I would suggest something in the 650-680 cc range. I think that would be perfect for around 20ish psi on a 50 trim. If you are tuning with dsmlink or something eprom based though, I would go as big as you can afford. Its always easier with those type of setups to go bigger than you need rather than smaller.

I would say 1000cc would work just fine

Agreed, but I would go with 1000's or something around there if e-85 is available in your area.

I don't have experience with e-85, but if that's going to be used you would definitely need larger injectors. I was just assuming that it would be on 93 octane or something similar. I forget the exact number but you need a certain percent more fuel with e-85 to match up with the effect of unleaded. Maybe someone with more experience with e-85 can chime in. Also don't forget that with the wally 255lph pump you will need an afpr. You may have known that but I didn't see one in your profile so just thought I'd throw that in as well.
