Cool build! I'm always more interested in the builds that are out of the main stream. (how hard is it to build a small/big block ford)
The holsets are pretty cool turbos but they don't move a lot of air at low psi in a restrictive system. With the porting you are talking about I hope it will make the numbers you want at low boost levels. My hx35-40 took 35psi to make big numbers.
Keep us updated.
