GT30R .83 owners I have a question for you.
Are we talking about full boost on the dyno again here?
A 35R sized turbo with a normal hotside on a 2 liter should give 25 psi in 3rd gear at less than 4500 rpm. It always did on my 2.0s anyway. Same turbo on a 2.3 reached the same 25 psi at 3700. A 30R sized turbo (SBR GT12 in this example) reached 25 psi around 4000 rpm on a 2 liter, and I never ran a turbo smaller than 35r on the stroker so no comparison there (hence my request for boost threshold data for a 3076 on a 2.3 in another thread, still waiting for some info). This is all on the road in third gear, boost threshold is always higher on a dyno. It just doesn't load the motor the same way.
