I have been looking at the Borg S400 series of turbo. I spoke with a guy at Majestic Turbo in TX said would be a good place to start. Seems to be a bigger poplular turbo. I imagine an Air to Air intercooler would ward off detonation as well...

SOO, how much compression can you get away with on pump gas? Seems 9.5:1 is about it..

93 octane around here.
