At what point are larger injectors needed. I have an 89 Turbo these are the mods i plan on using will this setup need more fuel.


K&N FIPK

3" Turbo back exaust w/high flow cat by CM

240sx throttle body intake port to match

boostvalve manual boost controller (10psi)

NGK plugs, Accel wires, Accel coil

JWT ecu upgrade

Unorthodox crank pulley

Auto trans upgrade. Any help on this one would be cool. I want to keep the auto.

And yes i plan on using more accurate gauges and maybe go to 12psi with the boost but im not sure yet. What are the chances this setup will get me in front of my buddys 90 turbo eclipse, he rang up 230rwhp on the dyno. I havent had a chance to go head to head with him yet we cant seem to have both cars running at the same time mine needs a new motor the snap rings shattered.

 

Read this FAQ, grasshopper. Then come back to us.

BTW, loose the A/T. They don't hold up well in unmodified z31s. Put any real power to it and you'll need a wheel-barrow to haul away the pieces.
