I have an 87 grand national turbocharger. Will the .48 or .63 housing made by turbo netics fit it? I tried to swap a .48 on mine from a t-bird to no avail.

 

As long as its a standard shaft housing(stage 1) any .ar housing should fit.

You have a .63ar ford housing?

 

No just a .48. I am problubly just going to make a flange for the 3 hole GN flange. It is a .63. The .48 t-burd T3 exhaust housing rubbed on the turbine and hense it would'nt fit. I have yet to measure the turbine though....
