The turbo is small, but with a few mods has excellent torque, it helps get the jump on cars, and by time they start making more HP and catching up the race is over.Originally posted by gryphon
It's not that is has no top end power, but several things combine together to make it... less powerful up top:
1) small turbo - runs out of breath after 6500rpm
2) no VVTi/VTEC/AVCS - STi heads and ecu would help
3) long 4th gear
There are solutions, but it's got just a great punch off the line that the top-end looks horrible in comparison. It's really not that bad. MBC and an uppipe and your top end will be just fine
Having no variable cam timing gives the WRX less flexability, but I think it's tuned for the top end. We suffer a little down low, but corrected by driving style, but can breath well (once the engine is broken in) up top. Overall power is about the same.
A long 4th gear is awesome, you take third up to 7000+, and you are landed in the sweet spot for 4th, which takes us very quickly up to 120. Now 5th on the other hand is the WRX weakness...if you're hanging with us till then, you're probably gonna pull when we go to 5th. At least at stock to moderate HP levels. 5th is way underdriven and just plain sucks, cuz the engine isnt powerful enough (at stock levels) to push it along.
