Can individual gears be replaced in the gtr box? I have just had a quote of $332 for 3rd gear by itself direct from Nissan.

Yes, best to speak to a gearbox place tho Labour would be more than that. And once you're in there usually worth replacing syncros as well.

Thinking of going with the croos mission gear set at this stage. I dont want to blow one gearbox after another, no use rebuilding it fresh standard and having to pull it apart again. When i was younger i spent more time fixing my cars than driving them , I'd like it the other way around now.

Ok, so i am looking at the folloeing two options the 1st-3rd OS Giken or the 1st-5th set. Is it only realy necessary to go with the 1st-3rd gearset?

[T04GTR]

5th option if you want to do trackwork. but you must get the upgraded input shaft.

[fieds83]

Cool, just got my quote from greenline at $2730 delivered for 1st-5th including uprated input shaft. Still waiting on the price for the 1st-3rd but i think i will go with the 1st-5th anyway.

Does the OS gears use scynros or are they straight cut?

[fieds83]

Synchros.

Does the OS gears use scynros or are they straight cut?

FYI incase your interested- You can have a straight cut gearset with synchros. You can also have a helical set with dog engagement but nobody would do it. The OS sets from memory are a straighter helical gearset than the standard ones which makes them noiser but obviously stronger.

Hi guys I just got another gearbox for my 33gtr pull type now there's a few diff things bout bell housing the new one has pps written in 2 places and my old one series 2 gtr 33 has no print on top at all also the new box has no air vents on top where as my old box does have 2x air vents on top of bell housing another thing with the new box it has a different spedo sensor by the looks and a diff plug the other 2 sensors are the same as the old one.
