Travis, I have the 20g and Byron has the Green. We could tell you first hand anything you're wondering about. I don't have the compressor maps handy, but if I come across them I'll post them up.
30r would be a real sick street/strip turbo if you don't mind going rotated.
If money's not really too much of an issue, I would suggest the 30r with Meth injection and a FMIC. That would be yummy

any insight as to WHICH 30r?... perrin has the 3071r and 3076r in both .63 and .82 hot sides... i honestly want to stay away from meth and run on either straight 93 or straight 112.. less variables thus less possible failures (in theory) i dont mind the whole rotated mount assy idea.. i just want reliability and somewhat decent spool.. 35r from what i hear is too laggy for what id prefer and a 20g isnt reaching my preferred power goals..

NINJA EDIT!

mike, what snail do you have on rexer.. i mean, that is if rexer still exists

I think some of the alky injection kits have a form of fail safe on them now, because other people have the same concern of what happens if I'm running tons of timing and high boost and it doesn't spray.
As far as which 30r to get, the bigger hot side will give you more top end obviously, but will come on a little later, vice-versa for the smaller hotside.

Anyhow, you NEED to plot your engine demand lines against the compressor map

Who cares about spool? Boost <> power. You want the TQ during spool up. It's GOOD that your "lagging" if your ramping up.
