R33 Gtst Shifting Problem

[bingy iree]

AMI am having a difficulty of shifting from 3rd gear to 4th gear at 140kmh or 140+kmh. There is is always a " CRUNCH " noise when i shift from 3rd to 4th. but only in high speed range.

I've got a C's short shifter at the moment on my r33. My mechanic had that shifter on his 180sx(sr20) and i was told that shifter from 180 also fits o r33 gtst s2.

The noise may happen due to the gearbox syncro faults or else bcoz of that short shifter i have.

Can anybody tell me what exact problem is if somebody have experienced this ??

thank you

Synchro may be worn and having trouble matching revs at that speed.

Short shifters are a good way to thrash synchros out.

Short shifters are a good way to thrash synchros out.

It has nothing to do with the shifter if it operates the same way

People tend to fang a short shift harder is the problem , the short throw is less time to mesh for slap happy drivers " not double clutching yo"

Get a Nismo one they work a treat

Well, that is exactly why they are a good way to thrash synchros out.
