It wont make good power till around 4500-5000 range and up. Not very responsive compared to your GT25. Unless your looking for 500+Whp then I doubt you'll like it.

A GT28 or GT30R is probably more your style. The GT35R is a 600whp turbo, while the GT30R is capable of about 500WHP maxed out, and a GT28R is capable of about 400whp depending on the type. These are the absolute max power figures at the wheels, most will run them 100-150whp less then that.

How much power are you trying to make?

I just had it laying around so i though about using it. i dont care about the respon as much but if it revs from 4.5-8k then that good enough for me. looking to make 4-450 hp sooner or later. you think if i change the exhaust i get better response?
