My '02 wrx has 75,000 miles, just changed the plugs and still has no high-end power. It starts to bog down at about 5000 rpms and has no speed build up from that point, in all gears. I'll admit I haven't been very good about the cool down time on it, could it be the turbo ? Please any suggestions.

No speed build up?? Something is def wrong..
Boost should be dropping if you run a mbc, but you will def. have speed build up...

I agree. Boost builds...compression leaks...engine go boom
