I've been meaning to update my thread about it, but to be honest with you, The old GT30 with a proper Garrett .63 housing would have done the trick.
I'm a little disappointed at the extra lag, but it still goes well. I'm about 400rpm laggier now. The top end is definately better, but I think it could have been more? Maybe I was just expecting too much? Lol, I should have got a GT35 with a .63 housing.
None the less, there was definately nothing wrong with that old 7 Blade GT30 I had. Made a lot more boost down low than the 6 blade wheel. Maybe because of the chopped up RB25 housing, wo knows.
I'm still contemplating taking the .82 housing off and whacking a .63 on, just not sure what sort of Top end I am going to miss out on.
