When I bought the car there was an old school FP Green turbo on it. Owner bought it new, it's approx. 8-10 years on the car and never been rebuilt, I'm still rocking the same turbo. I bought a GT30 on here a while ago, but never installed, sold it again. I like the green, it's spool time is nice and well if it isn't broke don't fix it is my thoughts. It'sa a great turbo for Auto X. I'd have to check on full boost, somewhere in the mid to high 4000 range IIRC.
