Honestly I'd look at a different GTX30R - the 3076 has some inherent disadvantages because of the size difference between the turbine and compressor. What are your power goals for the T5? I did a match simulation for Homer and found that a GTX2867R or GTX3067R would be well matched for one of these engines at anything south of about 450 flywheel hp. That's for pump gas and a fairly stock 2.3L making peak power at 6krpm. If you're looking for ~500 hp at the flywheel, I'd look at a GTX3071R.
If you need the airflow provided by the 76mm GTX compressor wheel, the 35 turbine is a much better match and makes for an overall more efficient system.
Makes sense to me. I wonder why ATP doesn't list the 3067. I was very happy with the 3071r on the old t5r. This one should wind up to about 8k and I'd like a bit more omph... But maybe the gtx3071r with an 82 exhaust side will be plenty.
I've never driven a gt35 that didn't feel a bit doggy in daily use but maybe the gtx would cure that. Honestly I should just stick with what I know I liked lol
