Im not gonna run crazy boost ( right away https://www.nopistons.com/forums/pub...DIR ). Just 10-12psi. Would I need more fuel than that or no?

Are you getting those cheap or something? You should just run the stock primaries and 1600/1680cc secondaries, better idle and will support a enough fuel for any psi on a to4b/e. Transition will ofcourse be a little harder to work out..

Hybrid or full?? You'll be fine. You'll be just around 85% duty cycle.



I had a hybrid t4 with 550/720 and was hitting 85%-90% duty cycle. You should be fine with 4x720 @ 10psi but must get it tuned.

Turborotor, what 720s do you recommend? I am thinking of buying the Greddy ones.

I was gonna get 4 ND's for $200 from a friend but I think I might just use the stock primaries and get larger secondaries like was suggested.

What ever is cheapest. As long as they work.





Either way you decide, you can't never have too much fuel.

What are your plans for the car, autocrossing, or drag???

Drag, all the way. What I meant by that comment was, what was your source?



Jarrett

550/1600 is the way.



Years of experimentation and experience. I've been down that road alot of times

If youre running an E6K, could you post some of your maps?



What turbo are you using?
