Wow...you need to search before even consideringa bridgeport.

But anyhow, I'll help (in the way I can).

You'll need a full standalone or (gasp) carb.

4x550cc injectors might be alble to do, a person I know is using that and a FD fuel pump for their bridgeport. More may be needed depending on the tune.

SAFC won't be able to do it, with a bridgeport and big HP the weakness in the system is the AFM, manifolds, and stock ECU.

Consult Scathrat for anything to do with nitrous.

TII tranny may not be needed considering it isn't HP that breaks a tranny, its torque. You most likely won't me making enough. But if you do and don't want to swap drivetrains go with:

RacingBeat NA engine to T2 Tranny clutch
TII tranny
Mazdatrix T2 to NA rear end.

Jacobs ignition: http://www.rx7.com

Search for what bridgeport builders so differently (if anything).

If you have to ask, you can't do it. Sorry, but it's true. Tuning a bridgeport is funky, to say the least.

At the very minimum, I would run 4x 550CC on an NA bridgeport with a standalone. If you are going to use nitrous, then you will need larger injectors depending on how much gas you give it. Fuel pump upgrade is also a necessity.

Tuning a bridgeport with nitrous and not having experience doing it is a sure way to go through 3 or 4 engines while learning.
