Does anyone know who makes the Turbo in the redline? Any info on inpeller/turbine size or materials (ceramic?), CFM, or other specs? Understand it is also used in a Saab. I thought I read that full boost came in at at 2000 rpm, this is pretty good, even for a dual scrool turbo. Pictures of turbo shows it has plenty of wall thickness for serious porting. But if it only produces 17-19 psi at 5300 - 5500 rpm and can't hold that to redline (rpm) porting turbo may be a waste.
