ive noticed that compare to other sr's mine doesnt rev up as fast,
almost like the flywheel is too tight
its a blacktop, t25, fmic godspeed , hks bov, spec 2 clutch
the car runs and boosts fine, it just climbs through the rpms too slow
anybody have any ideas what could be causing this problem?
could it the something w the flywheel???

how can i check if the tps is misplaced??? i did take off my intake manifold when i got the motor because it had calcium buildup
how can i check the timing??? idk if the motors been opened before so idk, it looks pretty stock
im running the car at 10lbs and still feels pretty stock =( helllpppp

id def. check for a boost leak
as for the tps, its located on the right side of the throttle body, it should have a red connector, but check it for bent pins i knew a buddy who bent one whop had kinda the same problem

You should do a compression test to make sure your engine is still in good shape.

And there is nothing wrong with your flywheel...

after lookiing at the engine bay for 20 minutes and making sure everythign was bolted on right i found that the o2 sensor wasnt crewed all the way in =/
that made a lil differences, then a friend came by and we realized and i would give it full throttle the throttle body wouldnt open all the way so we fixed that =)
ima check for a boost leak tomorrow at a this guys shop
thanks for the replies
im kinda new to sr's, be patient ill catch up pretty fast =)
