i have a T3 Garrett turbo, generic turbo manifold, piping and cone filter from cold air intake. no intercooler will be running at this moment. obviously this is the simplest form of FI cuz im new to this. stock DPFI and stock injnectors, stock everything. tuning will be done. i have the supplies for boost and want to go as high as 4psi until i have cash for internals and convert to MPFI. i have a d15b2 with a d16a6 head. stock clutch (replacing ASAP) 1990 civic. the motor might put out close to 100hp and 8otq without the turbo. wut kind of results can i expect form this? ive been told about 10hp per psi of boost. anyone have any better estimates or recommendations for this setup. my exhaust is stock 1.5 inches i think or 2 inches max. might install a cut out valve i think its called? to go onto my exhaust piping and open up and free the engine.
