so about 7 weeks ago a spun a rod bearing on my 02 wrx i then bought a replacement used engine in town. turns out the engine i bought had the bearings starting to go out luckily we caught it before we put it in. So we had that engine taken apart sent to the machine shop everything was cleaned and chemical dipped also crank was machined and balanced and polished. we used acl rod and main bearings and wiseco pistion rings. well we were doing this we did a few upgrades. So for total upgrades i have 3" exhaust upipe, downpipe, unequal length header, short ram intake, 1000cc injectors, stage 2 clutch, lightweight flywheel, 20g turbo and tuned on E85 what do you guys think i should run for boost on my old set up with stock turbo clutch and flywheel i ran 20 psi and that was fun but id like a little better out of this
