I'll be looking for a cheap s/hand T28 shortly. While I'm buying though, I'd like to pick the 'best' one. So what's the go... S13, S14, S14A, S15, GTiR etc... what is what, what's best, how to identify, what to run & hide from, etc.
Turbo is to support 220rwhp at around 10psi. The only other thing I may consider is the single turbo off a late model 1JZGTE. They seem to get pretty good reviews...
I also intend to sit on my hands until such time as I can buy one for three dollars and half a can of coke from boostcruising.
