What Transmission are your running for ur boost?
most budget friendly setup is probably a Turbo 400...not hard to get them really strong...
The 400 is definatly a great choice, the 400 and 4L80 share alot of the same parts, and are equally as strong. The only draw back to a 400 as compared to the 4l80 is no lock up convertor, no over drive, and you will need to thengthen your driveshaft, and the transmition control can not be done with the PCM in the car (at least I do not think).
If it is going to be used mostly at the track, and you do not expect the car to get better then 12-13mpg on the hwy, and do not plan to drive it on long trips, then the 400 will fit your needs. If you want the strength and reliability of a 400, if you want it to do everything a stock car does, then the 4L80 is the ticket.

If it sees freeway time= low mile salvage yard 4L80E with Transgo HD2 shift kit, leave the rest stock to save cash. Yank converter, expensive but worth it.
If its a track/weekend car= TH400
