I think any Enforcer 2 turbo's I've taken apart were stage 2 turbine wheels, either in .48 A/R or .63 A/R housings. The 50 trim was a stage 3 turbine wheel in .48 A/R housing. (maybe that's Enforcer 3?)
Also, I've seen these turbo's with the stock compressor cover just machined for the larger wheel and that's it. I've also seen them with the compressor cover machined for the larger wheel and nicely ported open for more flow (prefered)
So there are a # of variables that will determine spool/ power/ efficiency, but the simple fact that you know it's a much larger compressor wheel in a much smaller housing tells you that the #1 problem is going to be the extra heat it's going to make in boost, so the I/C will make or break what you want to do with it.
I can't tell you how laggy the .63 A/R will be on there without knowing a lot more about the build, it Shouldn't be to bad.
How soon till you take it for a spin? Ever been in the car when your buddy owned it?
