Turbo change

I had assumed that was a driving factor. They do make a t4 version.

The 3076 compressor flows plenty, but the exhaust side is too small for a 400” motor. Would probably fall on its face around 5k rpm.
The 3582 looks to offer several setups also. Which combo would you go with.

So if I go with the 3582 which combo. Comp/turbine? Try and stay near a 62/ 81
