Sup I'm David. I've probably met most of you GA people. I just dyno'd my SR last week. As far as mods that would effect results: 3" exhaust, turbo xs mbc ( 14psi ), Front mount, everything else stock: t25, injectors, ka maf all stock.

Put down 237.9 RWHP ( ~5k-5.7k rpm ), 260.8 Torque ( ~3.6k-4.6k rpm )

boost @ 14 psi, timing @ ~15btc

I'll try to scan the printout so you can see the graphs. They're pretty smooth, I only took it to 6500 cause after that it falls down and there's no really no point in red lining ,but all in all I'm pretty pleased. I was expecting in the 220ish hp with the same in torque, so the torque impressed me. I'll be getting my safc2 this weekend, and whether or not the machine shop's done with my rear sump oil pan for my rb25 or not, will determine if i rob 4 of my 550's and z32 maf from that.

I'm curious to see some other dyno's on t25's, make sure you put @ how much boost. Z U L8R <=]

Those numbers are the a-typical standard for an SR with a stock turbo.

I pretty much have the exact same setup and dyno my car at 15psi and made 233whp and 266wtq. But i was running rich and a big exhaust leak. Whenever i fix my exhaust leak and install my powerfc and tune i dont see why i wouldnt hit over 240 or 250whp range.
