I think John Wilde may know something about them.
Wow my ears must be ringing.
The GT-42s are great turbos.
We run a set of the GT4202RLs on Chris's Car.
The GT4276 that you are speaking of is rated at 1200HP.
You can get it in a T4 or T6 Thumper Flange.
For the T4 that will work fine in your application you can get it in 4 different exhaust housings.
1.01 AR,1.15 AR, 1.28 AR, 1.44 AR
The GT Series turbos seem to spool fast.
This might be a good choice for your tight converter you would like to run.
The 76GTS is really nice but is smaller. It is rated at 1150HP.
From what I have heard they can have high back pressure if you turn them up. You would probably be ok because the motor is small. The GT42 has a more effecient exhaust turbine in my opinion.
You can get it with the a .81 or .94 AR.
In addition the GT42 was about $200 cheaper the last time I checked.
If I were you I would purchase the GT42.
