Attention: TDR Forum Junkies 
How would this turbo be for a bottom on a twins? Overall goal is 600-650 drivable horsepower. I would use the stock 35 on top or possibly a 35/40. Can you buy different turbine housings for this turbo? Because as it is now I would think it would be way too tight. Although it could be a misprint. I was looking on the Garret website and the smallest A/R they offer for the 45 is a 1. 01.
Garret GT45
Turbo flange = T4
V-band = 4. 25"
Compressor
Inducer = 80. 8 mm
Exducer = 108 mm
Trim = 56
A/R = 0. 69
Turbine
Wheel = 87 mm
Trim = 85
A/R = 0. 64
I need to do a few upgrades before I can run HP that high but I thought I would start buying parts for it now. What do you guys think?
