Ok, I'm just fantasizing here, so bear with me. I have a complete 2.3T motor and IHI Turbo from an 88 TurboCoupe on an engine stand in the garage. I am probably going to rebuild it to "slightly better" than stock specs before putting it in the Mustang. So here's my question: What would a reliable and proven upgrade to the IHI turbo be? I know it is a T3 from the earlier TurboCoupes/SVOs, but what about about a T3/T4 hybrid? Also what trim would you suggest? Realistically, I'm looking to get about 275-300 RWHP from this running about 20psi. I already have a gillis boost valve waiting for when the engine goes in. Any suggetsions? I have to admit that I'm completely lost when looking at the .57, .60, .63 a/r, etc.
Thanks,
WES

I would think you would do some porting on the head before you starting on better Turbos
