20B street turbo suggestions?
Although its really easy to find lots of info on this forum about 13b single turbos, 20b setups are a bit more few and far between. So here goes (and hopefully this will be a good thread for people who are searching)
What would people say about these turbos for a street ported (racing beat style) 20b engine? Here are the goals:
Run on 91 octane fuel (so maybe 15 psi limit)
No less that 475 hp to the wheels
Fat power curve (full boost no later than 3500 rpm)
Now, here are some of the turbos i was thinking about:
GT40R
GT42R
Turbonetics T66
Turbonetics T72
Turbonetics T76
Greddy T78
What do you think about these choices? Since its a 20B, there is no divided manifold obviously. Lets hear what you have to say or if you have personal experience or other turbo suggestions. A good thread for those who actually use the search function would be great ;-)

One of the best turbo's on a street ported 20B is a GT42R, I can get them pretty quick If wanted, I would say the 40R is going to be slightly on the small side depending on the port. It's not that the turbo is to small, it's that the exhaust housing will only go up to a 1.06 in the 40R which is on the small side for a streetport 20B. I would say if it were my car it would be a GT42R with upgraded comp wheel. This would produce big numbers.
With spool being very close to what you are asking, full boost is a relative term by the way.However this would not be a 15psi setup either, if your only going to run 15psi on 91, than a GT40R. would be really nice with a wide powerband.

you can make 475 on a 2 rotor, why dont you set your goal a little higher man. seems like a waste of money if you dont get some serious results. Some people are making around 550 rwhp on the stock twins at 15 psi

Graham, is this for that lovely 20B Chris just put together for that saidrail in the Midwest?
This thread/question is for my new evil project that ive been conjuring my head for the last month.....
Planning on selling my FC soon and getting a daily driver car then using the rest of the money to start my project.

So does anyone have any more suggestions for a single turbo setup that meets my requirements? ZeroR had some great input, lets hear some more!
