Gearboxes...

[djr81]

The syncro's in my R32 GT-R gearbox (4th gear) are basically cactus. I have tried the redline oil change, but to no avail. Can anyone pass comment on which of these three options is preferable (& maybe recommend some workshops):

1: Buy secondhand box.

2: Get existing box reconditioned.

3: Buy an exchange box (Which is what I would do for a Foulcan/Commode - but I am not sure if they are available for GT-R's.)

Get a good 2nd hand box..

Djr,

Unless you can exchange your box for a second hand one I'd look at rebuilding yours.. otherwise you end up with a spare box that no one will want as it's broken.. How much power do you have / intend to have? Might be worth getting a cross set for your box from OS or something similar..

Having said that there is a guy selling gtr boxes for like 1k in the for sale section..

Output is a miserable 310rwhp, so I don't really need straight cut intermediates or anything.

I was hoping someone may have gone through this previously - shot syncros is a fairly common problem. Can anyone recommend a workshop?

I know Ant at SST has rebuild a few of his GTR boxes, could give him a call.

Got a 32 GTR box if your interested.....

I have exactly the same problem and asked SST this question yesterday. I will be getting mine rebuilt as the problem with second hand boxes is unless its in a car you dont really know its condition. Chances are their syncros might be stuffed also. and you end up with 2 boxes.

Bunbury Transmission & Driveline Specialists if you want a rebuild...

sounds like a worn selector fork and ring common fault with r32 gearboxes .my advice rebuild it with new fork and ring ,get internals cryogenically treated and have a tough gearbox that can cop a thrashing with no complaints.had mine done and cost me $850 and have 390rwkw at 7500rpm launches no probs.
