i am having a 1996 wrx engine rebuilt at present -what can i do to get a higher rev limit??
martin
ps i used tio have a p1 which had a nice high limit

 

Is your car revving to about 7000rpm?

 

on normal wrx heads yes but thinking about getting engine higher revving so just wondering what this would involve?

power fc

 

if its a early 96 (4 plug ecu) you could get a chip with a raised rev limit, from say a wrx ra

 

i will find out
thanks

You will end up spitting a a shim or dropping a valve , if you raise the rev limit on the standard heads as they have over bucket shims and basic valve springs.

What you need is STi valvetrain to get the 8k rpm rev limit, this includes the underbucket shims and stronger valve springs to reduce the risk of valve bounce at high rpm.

ahh sounds like more money lol might give you a ring to ask more about it
