How to identify which series GTR gearbox


Recommended Posts

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

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:spank:

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

    • Yeah the Drift R wheels look awesome. They are pitted though, wonder if I can fix that somehow.
    • I picked up my diff today. Both their shop manager and machinist wanted to have a chat prior to me leaving. Conversation started with "Where did you buy these garbage parts? What's the name of the company?" They actually went on Speedtek's website during our conversation and made what I think is the best gear head joke I've ever heard after seeing they make straight cut gears. "They've probably only gotten away with selling straight cut gears as they'll make noise whether they're properly machined or not. People are none the wiser" The humor made the 2500$ in the hole I'm in after this whole experience a little better lol. They also pointed out that not only did they find identical issues on both ring and pinions that Speedtek had sent, but that by eye you can see the pinion teeth do not have the same profile from one end to the other.  They went on about this being the worst diff job they've ever done and how it was a colossal waist of time. Luckily after mentioning how I purchased another diff to learn how to assemble them, they were nice enough to give me a crash course on diff assembly on another diff they were currently doing. I like to tell myself they did this to be nice but deep down, I know it's to be extra certain they'll never see me there again lol.  Speedtek was pushing for a store credit but I'll never feel confident purchasing from them again due to their third world machining techniques and QC. I just asked for a full monetary refund.  I'll pop the diff back in this Friday and take it for a spin if the streets are clear of snow.
