So I purchased a car already partially built that om trying to finish this year. Boost is new to me and I need some insight on what I should run. Engine is a 5.3, btr 660 springs, TI retainers, moly PR, and stage 4 turbo cam, 234/239 .612"/.610" 115+5. It has a full on3 kit now with hotside installed. Will be ran with a stalled th400. Any help is appreciated, thanks!

Correct, it has a t4 flange. Vehicle came with the base on3 70mm .70 ar. From what I understand this is just entirely too small and will choke the engine on the top side. Especially since the cam is going to want to make its power up top.

With that cam it needs like an s485 from forced inductions. If it was a street car i would swap the cam and install something more street friendly s475/87 in like a t4 1.10-1.24 housing.
