.70 would be nice for a race only application, but for a daily driver, a .63 A/R will give you decent spool with lots of top end fun

Where are you getting the .70 A/R T3 Exhaust housing from?
There are T3/T04E's or T3/T04B's!
These are all the different T3 Exhaust Housing configurations:
.36 A/R
.48 A/R
.63 A/R
.82 A/R
1.06 A/R
These are the different T3 Turbines:
Stage I
Stage II
Stage III
Stage V
These are the different T04E Compressor Wheels:
40 Trim
46 Trim
50 Trim
54 Trim
57 Trim
60 Trim
These are the different T04B Compressor Wheels:
S-3 Trim
T-5 Trim
V-1 Trim
H-3 Trim
There are several different T04E compressor housings and several Standard and Hi-Fi T04B compressor housings!

Liam,
It has been proven many times that with a high rev motor, a .48 A/R exhaust housing will cause the turbo to die out early in the top end. The .48 will be good for lower rev cars. Definitely go with the .63 A/R exhaust.

Rob92SC, you are the main one who steered me to the .48 A/R housing. I trust you when you say on higher rev motors the .48 will crap out and it needs a .63. I am in favor of sacrificing a little low end boost response for killer top end.
It's all a matter of preference!

Can I safely convert a new T3 to a T4 by just swapping compressor wheels and housings or does it need to be rebalanced with the new wheel?

I have a 60-1 with a monster 82exhaust housing. Car is not that laggy, maybe I am used to it. When this bitch hits bull boost around 4800rpm, it sounds like a jet coming to the folks listening to the car and it pulls insanely. My friend who has the same setup as me has a .63exhaust housing, I am going to run him at same psi(20) and let ya know what the results are.. I think he is going to out spool me but maybe I will get him top end.
