57mm turbo is not going to be big enough
If you do run it you will need to go with a large A/R on the turbine side. I would say atleast .96 or larger. I would also go with atleast a 60mm wastegate. The red mustang I posted above is a 306 and I started off with a 61mm turbo with a .68 A/R housing on the turbine, and even though it worked you could tell the small turbine housing was holding it back in the upper RPM range. I upgraded to a 70mm turbo with a .96 housing and it made a huge difference. The turbo would light almost instantly and never seem to quick making power. Boost for both turbos was controled by the 60mm wastegate pictured.
