Which turbo: RB25DET or RNN14 (Pulsar) T-28 for the SR?

[bulgartkd]

Hi Guys,My T-25 is gone bye, bye and I need to replace it. I have the option of obtaining the stock turbo from either the RB25DET or the Pulsar. Can I use either one of them and if yes, what are the mods to be done? I really would like as much as direct bolt-on as possible, but I can't seem to find a decent priced S14/S15 T-28. If those turbos are hard to make fit in the SR, I guess I will have to look for another T-25 at this time. Your input is much appreciated!P.S. I do have a 3 inch turbo outlet and downpipe.
