Turbo sizing and Garrett part #

I need help with a Garrett # and sizing. My turner said need a 76 or 80mm for my motor size (414ci). I know the turbine ar needs to be lower because it is the rear. The one I'm running now is way to small and causing me to run lean at higher rpms due to it restricking the exhaust. I have a local shop (Garrett dealer) but they only do big trucks and tractors and can't understand what I'm trying to do, but if I had a part # they could help me.
Any input and help would be great.

GT88 is a awesome piece for that motor. Also how much power are you wanting?

Trying for somewhere between 650 and 700. I'm also not wanting to spend an arm and a leg. I'm too invoved in this project now. I,ve was a couple hours late on a 76mm on the for sale thread a couple days ago and have been shopping on ebay for a used or rebuilt unit but no luck. This shop here thinks they can build me one with the stuff the have but the need specs. or a part # to study. I don't want to spend the money on a ball bearing right now.
