Digging this oldish thread up again, thought I'd add my opinion after just having -7's fitted to my Stag. After a quick run through the hills I can say that there is definately a lot more power there than I had with my old 34 turbos. At this stage I haven't had it re-tuned (running a PFC) but it pulls so much harder and the response seems to be the same as the old turbos. My mate has just bought a 33 GTR with -5's (with a built engine though), so will interesting to see how much quicker his car is. I'm definately not disappointed with the -7's, but it is a daily driver after all with a stock engine. If it were a weekend car with a built engine I probably would've gone the -5's.
