I was just wondering which turbo makes the most power on 93 octane pump gas for our cars?

PS: alcohol or meth injection doesn't count ;)

Also, let's assume the car had all the proper supporting mods, such as full TBE, FMIC, bigger pump & injectors, etc..

If you got a custom GT40r turbo it would take it i think.

To a point the bigger the turbo the more power it would make on pump gas. Your power band would just keep moving up and up and up in the rpms. A larger turbo is going to flow more effiecently than a smaller one giving you more power at a given boost. From my experience on our cars with stock compression that limit is right around 20psi before you start getting knock.
