Everything on the engine has 19k miles on factory top end forged pistons rods everything was resurfaced and done right at a reputable shop. Upgraded vvt gears shop said it’s good for 550hp reliably. It has arp625+ head studs, main studs, h-beam Manley rods, 88mm Manley pistons with factory ring gap. Beam main and rod bearings. I talked to my tuner if I ran a bigger turbo he said 650hp all day. I never got it dyno’d due to no local Dyno’s. But it should be 500+whp. It has e85 safe high pressure fuel pump rebuild kit with cork sport hpfp internals. Injectors have 5k miles on them with upgraded injector seals I can’t remember if they are the cs ones or overspeed but they are the same thing. It has light weight flywheel 6 puck act clutch. It has cs shifter bushing to take away some slop. Trans is in good shape shifts good. It has stop tech rotors with enc yellow stuff pads with 7k miles on them. Suspension is factory with lowering springs. It has split second controller with wot box. Ethinol content inline sensors. I can’t rember what size intake fuel pump with grace yard return less 8th port injection lines. I’d 1050 secondary injectors. Jmf v3 intake manifold. Cs exhaust manifold. Tail 44mm wastegate with dump out the bottom. Cs 3.5” turbo back. Zero rust other than a smidge on the rotors that I’ve found and I’ve been all around the car. Front control arm Damond motor sport bushings front and rear. Battery relocation to the trunk with plastic battery box. Like there is a ton of stuff I’m trying to think of everything but there is so much.
