alright so i got a gsr im building for boost. but in my car right now is a z6. i love the gas saver, and want a little more fun out of it. I already have a ebay cast iron manifold with the wastegate flange on one cylinder, but im thinkin about blocking that off and running a internal wastegate turbo. maybe a T25 off a twin turbo 300z A/R 48. like this one. link
idk if this is a good turbo to use.

I just want this to spool quick, for a little more fun.

My power goals - high 100whp maybe a little over 200. This is my DD

Budget - 800

Good setup? Input?
