Hey man, I am not sure about some of the others you have mentioned, but I have a GT28R on my B16A Sol. Its a rated at 320hp. I am currently running 9psi and I am told its good for 15psi or so. starts boosting at 2500rpm and comes on very strong at 3000rpm till redline. Its good for a standard motor and you can up the boost once you strengthen you motor.
