I think a 9.0 CR with a low compresion turbo, or a turbo with some meth or water added would be the best of both worlds.

For me. 43 psi base pressure and 68 psi of fuel @ 25 psi of boost.

For shure compression ratio is different from a NT vs Turbo 4G63.

1G 4G63 NT: 9.0:1 (192 psi compression)
1G 4G63 T: 7.8:1 (164 psi compression)
2G 4G63 T:8.5:1 (168 psi compression)
Galant 92+ 4G63 NT: 9.8:1 (220 psi compression)
