Need advise on turbo choice

Need advise on turbo choice
Alright, well Ive been looking around alot lately for an alternative turbo for my FC. Mods in sig, relavant things include large streetport, Greddy FMIC, etc.. I have a Greddy turbo kit which includes a Mitsubishi TD-07 25A turbo. While I have been told by many that this is a good turbo, finding specs on it, and others experience with it on a 13BT is proving quite hard. My other option that I am liking is a Garret T04E. Specs on this turbo include an exhaust A/R of 1.00, a compressor A/R of .70, and a P-trim exhaust wheel. I was just wondering if anyone would have any comments about either turbo?? My goal is 400 RWHP, and hopefully staying ~15psi. ( Dont really want to have to run more for that power level).Both turbos have a divided exhaust housing, and my manifold is fully divided also. Here are a few pics of each:
TD-07 25A
Garret T04E
Any comments about either would be much appreciated, especially about the TD-07. I really wish I could talk to someone who has experience with this turbo.

What's the compressor wheel on the T04E?
You can take off the compressor and turbine housings and take measurements... That should give a very rough estimate on what the turbo might be capable of... If memory serves me right, I believe Chris Ng made 400rwhp @ 15 psi with the TD07 (although that was a 25G). "25" refers to the size of the wheel... so it should be capable of 400rwhp... The main difference between "A" or "G" or whatever letters follow the number seems to be the shape and design of the wheel. This should affect where the turbo is more efficient more than anything else... but I doubt you will have to push the turbo to over 20psi to make 400rwhp.

^^ lol, there is no such thing as a GT3528. It's a GT2835, and it is WAY too small for a rotary. It would be along the lines of a T28 footprint.
The Greddy T78 would acheive 400rwhp no problem, but it's a rather large turbo for "just" 400rwhp.
The Turbonetics T72 is HUGE! It's bigger than an HKS T51R Kai!
