Hello to everyone, I'd like to get a sticky thread going, although there are many past threads just like this one. Its been a while since they have been updated and many people have changed their setups. No better time than now to list what you've done lately!

Please post in the following format, or one similar to it so that it is easy to compare everyone's setup

Motor: (RBxx)Engine Internals: (bottom end, top end)Fuel System: (Inj, rail, pump, regulator)Turbo / Manifold / wastegate: Management: (ems, rom tune)Dyno Results: (WHP & ft lbs Tq)

Motor: RB20Engine Internals: stockFuel System: stockTurbo / Manifold / wastegate: unfortunately stockManagement: stockishDyno Results: 212WHP at 6K and 201WTQ at 4200rpm stock redline at 6700 on a DYNAPAK so it reads lower then other dynos. Also its stock boost, which is about 10-10.5psi

This is all stock, tiny little SMIC and all.Planned upgrades include a slightly bigger turbo, 450cc or 560cc injectors, a big FMIC and Nistune.
