CORRECTION: positive pressure by 2400...5psi by 3200...10psi by 3800...20psi by 4400 (8v with ramhorn and 1.8t BT file)
I ran a HY35 on my 1.8t in my Corrado. It put down 342HP at 21PSI. Full boost was at 4800RPM. I later changed to a HX35 later and lost about 100rpm spool but did not notice much on the top end. I never had a chance to re dyno it. I did somehow manage to loose 5MPG going from the HY to the HX.
I have since parted out the car and used the HX35 on my 4runner

Ebay, freshly rebuilt for 250 bucks. Came with the high pressure holset actuator for some shenanigans later on.
Not a c-hair of shaft play either. They are tough to find, I know they were used on Case tractors, and I think the 4bt cummins from the frito lay trucks. Mine also has an anti-surge housing as well.
