As for choosing a turbo, I'd go with reading Garret TurboTech 101:
http://www.turbobygarrett.com/turbob...o_tech101.html
and Garret TurboTech 102:
http://www.turbobygarrett.com/turbob...o_tech102.html
and then looking through their product line:
http://www.turbobygarrett.com/turbob...ochargers.html
comparison sheet:
http://www.turbobygarrett.com/turbob...ison_sheet.htm

You really don't have to read the turbotech stuff, but it'll help you understand the dimensions of the turbos and the efficiency islands that they show.

If you still have questions about choosing one, I'll do my best to help tomorrow.

I would do this for you, but I feel like absolute s***.

How much boost can you get out of a stock ct26? And a 57 trim ct26?
Also I noticed on ebay there's a compressor upgrade. Any experience with these? Thanks for all the help!!!

I wouldn't go past 12psi with the stock turbo, but that's just me. I've no idea what type of boost is actually safe to run with it. Myself, I'd try to find a turbo with about a .85 A/R for lots of high-end, that you don't have to completely mash the throttle to get. That way it's still fun on the road, but you get good power and response on the track. I really know nothing about the 57 trim ct26, I just thought I'd throw in my thoughts.

Well, I ran what I believed to be the stock CT26 up at 11psi for just over a year (and the shaft already had more than spec'd play when I got the car with it's BHG). I expected it to last a few hundred miles before the smoke started but in the end it lasted over 10k miles & was still boosting strong & smoke-free when a failed BOV signal pipe that killed it in one fell swoop of surge...

That said looking at pics now I'm not so sure it was a stock supra CT26, compressor housing looks too big.

PSI doesn't mean all that much when it comes to turbo selection... Actually, it means very little. Think about the difference between a 6' tall industrial air compressor vs a small bicycle tire pump... both may be able to handle 150psi but the bike pump is going to have to work its ass off to fill the same size tank that the larger compressor could fill in a couple seconds.

Without getting into all of the specifics I'll just say that a CT-26 with an upgraded compressor will work quite well for what you want while maintaining a bolt-on setup and quick spool. 57 trim will run efficiently past 350RWHP.
