check the sept. 03 issue of scc. they basically make the RB sound like its so great. but mckinney motorsports was makin 350 to the wheels before the 100 shot of nitrous and that was on stock internals. im confident that it can handle just as much if not more boost than an sr20. i mean it has an iron block and with tuning a 2.5 will almost always make more than a 2.0. oh what the hell. ill stick with my 1.8t and stay out of this argument.
