I was at a meet in CT, maybe 2 years ago, and someone had a Pulsar of that boy type with an SR20 swap. I can't remember if it was a turbo, but I don't think that really matters for this discussion (if an SR20 can fit, you can turbo it, no?). Also, the owner said that he was using the stock tranny because he felt it was a much stronger transmission then one from a B13.
I have a soft spot in my heart for the Pulsar NX (check my signature).
I'll do some digging and see if I can get more information. Good luck, and welcome!
