Don't buy one with the stock bolt pattern rear. Get a genuine Garrett housing otherwise you might as well buy a GCG hiflow direct bolt on, Hypergear semi-bolt on, or RB25 specific HKS turbo GT-RS or 2835ProS/Kai.
They never make the power the compressor is capable of making so you get a penalty of the larger mass wheel with none of the upside.
A GT3076 on a manual stagea might be a docile off the line (due to the weight of the stagea) so for me I would choose something a bit smaller if you are using it on the street. It will still be a very nice bit of gear to drive if you want the extra headroom.
On my R33 a GT30 based turbo is a good thing but the weight of the car is so much lower.
