I am planning on Turbocharging my DOHC ZC.

I am wondering, should i be running 12:1, 10:1, or 8:1?

Also what else do i need to buy?

What else do you have and/or plan on running?

oops forgot, i am only planning on running 7-8 psi of boost

Dr.Boost

What about a pump, injectors, and an AFC? Is the FMU all you are planning on running? I would say 6 psi max on just an FMU at 12:1. Any more and you might be pushing it.

Yes thats all i want to run.

robs99si

what about a vortech fmu 12:1 disc, walboro 255 in tank pump & stock injectors, t3, eclipse ic, in a b16a. how many psi could i run? 7 psi?

Dr.Boost

I would say you guys are crazy for running any boost, but I know that several people run 6 psi with that setup. You would probably be safe at 6 psi, but I would suggest gauges to monitor things just incase.

6 psi max - it will run shitty(ie slow) and prob blow up soon, thats what you get if you don't do it right. at least get an afc or ghettodyne
