Opinions of the following turbos...

[scheides]

I'll only comment on the ones I've personally used.

14b: decent for a stock turbo, holds decent boost, and until you ride in a car with something bigger, you're sure it's the fastest thing out there! holds 18-20psi to redline just fine. Very reliable.

Small 16g: probably what the 14b should have been, except for the boost creep. Nice little turbo, spools excellently and provides good power. My 2g came with one on it, and I was really happy with it while I had it. Had shaft play along the line of the shaft like crazy, yet hardly burned any oil and still spooled awesome.

20g's:
Bastard 20g: big power in a small package. Spools similar to a big/evo16g. made 280whp @ 22psi @ LSE, 338whp @ 25psi@ DB.
Hahn Super20g: 20g power w/ kick-ass top-end. Spools much slower than my bastard 20g. ~4000rpms. Made 280 whp on a mustang dyno @ 18psi on pump gas

The Td06 20g is my favorite turbo in the world, because of how reliable they are. Anytime I look at a used T3/T4 setup it 'just got rebuilt' or some shit. There are reliable cases too.

SCM61: big power for little money. Probably my next turbo.
