How to identify which series GTR gearbox

[Dorifudo]

Hi all,

 

Long story short, I bought a GTR earlier this year with a blown motor, it's a 93 R32 GTR. Is there anyway to identify which gearbox this was removed from? Unfortunately at the them before putting everything back together this is the only picture I've got.

 

Cheers

Jeff

Hi Jeff, I have to say I don't understand your question.....but no...this pic doesn't help identify the gearbox in any way. Whatever that sticker is, it's not a nissan part #

Sorry, kind of realised what I had sent after posting and I had left it too long to edit the post. I was just wondering is there any way of identifying what series of GTR gearbox do I have, it has the 2 holes in the bell housing to identify its a later model gearbox, and whether the sticker would help.

There are really only 2 differences to be aware of with the 32/33 boxes.

Push vs Pull clutch. Some late 32 and all 33 clutches are pull style, other 32 are push style. You can tell which by looking under the car, if the slave cylinder rod points towards the rear of the car it is a push style

Series 3 R33 vs all others. There were changes to bearings and synchos in the last series of R33 gearboxes to improved strength. You can't tell identify that without a tear down

corrected a typo in push v pull

Awesome! Yea the slave is pointing to the rear of the car so at least I can now confirm it's an R33 box. Now the problem is downshifting from 4th to 3rd at high revs its crunching, so looking at options

Could still be R32 originally, but it's not as if it matters.

Sorry I just re-read my post (and I will edit it now for future readers). late 32 and 33 is pull, not push, I said push twice above

To be clear, since your slave cylinder rod points backwards, it is a push style clutch, which is the early 32 style. Which is probably better news, particularly for cost and range of replacment clutches

Haha. I even read it as if you'd written it correctly!
