My plans, set up:
I just rebuilt the L28ET, all new parts, honed block, fresh rebuilt p90a head, 3 angle valve grind, new cam, seals, etc, etc, etc. L28ET ecu, afm, dizzy, etc
Stipped intake manifold, 300zx throttle body (intake match ported), stock turbo exh. manifold, bosch jetronic fuel pump (from an 80's 535 bimmer), adjustable fpr, lightened flywheel, electric rad fan, msd 6 ign and coil.
Haven't decided on a turbo or intercooler yet (will likely go with the SIMTEC MOSPORT intercooler-- to replace the old bosch unit I had once scrounged from the wrecker), and a manual boost controller.
All very basic, for now. I plan on upgrading in the future, which is why I asked about bigger injectors, don't want to buy things twice.
I was running the same set up above (with stock turbo) on a non turbo L28E motor in the car prior and was safely pushing about 9 psi (but the engine had over 400,000kms on it and was time to be rebuilt, which is when I scored the complete L28ET !).
