the chrysler 2.2 turbo was a T28. The turbocoupe was a T3-60 on the early cars, an IHI RHB-5 on the 87-88's. The GN's had a T3 super 60.
Remember these engines were probably a little more efficient than the nash. And he doesn't want a high winding screamer of death. A T3-60 off a turbocoupe or an SVO mustang might be your best bet.
Buick GN's had a 60 MM compressor wheel? I don't think so,much smaller than a 60.
Buick regals had really small turbos,1978-1982??
