R32 Gtr Gearbox

[Ronin 09]

I've noticed that my R32 (early) gearbox is now leaking.

It's been a bit recalictrant through the gears for a while (still fine though), and 5th syncro is crap until the fluid is warmed up.

The options (cheapest to most expesive) are:

1. replace the seals only, run redline in it

2. replace seals, rebuild with new bearings and syncros

3. replace box entirely with new nissan late model series 3 GTR box (3500? + labour)

4. rebuild box with OS gearset (4700 just jap + 1400 new parts + labour)

Depending on the prognosis of how much (1) is, I am leaning towards option 3.

As the later boxes are pull type, and mine is push, is it simply a case of reversing the slave on the box and using the existing fork?

Oh and is is a bitch of a job to swap a box over?

any advice?

Yeah we went option 3 in the race car and I'm very happy with it, its lasted years of (careful) race use. much smoother, its a real joy to use compared to the 150000klm old one was.

Not really must involved in converting it back to push, you just reuse the gearbox front plate and fork from the old box and tap holes for the slave cylinder (the mounting points are cast in). So the only labour cost is R&R gearbox and swap plate over (about 1hr I guess)

I'm not sure on your prices though, I bought mine a fair bit cheaper than that. Just Jap have them in stock, not sure of the current prices.

2 just doesn't stack up price wise, 4 is the way to go if you are worried about breaking it. But under 300kw it shouldnt be a problem unless you abuse it.

Half a day with a mate and some good tools.

Save a shitload in labour.

thanks fellas, just priced it up and a new box is $2700ish. that's if they're in stock in JP...

I take it that this is how to do the conversion

RB Push/Pull Clutch Conversion

plus I take it this is really not necessary:

Clutch Pull to push conversion-

Late Model R32, R33

Front cover assembly :32110-05U11 (japan part only)

Gasket :32112-05U12

Clutch fork :30531-01S00 (same part for a 1991-1993 240SX)

Spring :30514-14600

Spring :30534-E9000

T/O bearing :30502-14601

Bearing sleeve:30501-S0160 / 30501-N1601 (14mm for twin / trip disc)

Bearing sleeve: 30501-K0404 (24mm for single disc)

Dust cover :30542-31610

Slave cylinder :30620-21U01

Flywheel bolt: 12315-04U00

Ronin, I take it that quote was ex Just Jap & recent? I am in the same spot you are at the moment, ie gearbox not happy.

[Ronin 09]

that price is from Nissan, AFAIK it's trade price...

don't think Just Jap has any at the moment

Cheers for the info. I briefly looked at their website - out of stock & more expensive.

RHD Japan want $3670.

I will have to chase up some contacts for trade prices.

FYI Mark from Hills Motorsport quoted me just under $2000 to supply and fit a low km R33 GTR box, filled with Redline. Not sure if it was series 3 or not.

thanks adam

just had a better look under the car - looks to be the transfer case leaking.

is it best to just do the seals on that guy?

If I were you man I'd drop the box and do a rebuild. If you're having problems with the syncros or gears you may as kill two birds with one stone.

If you have the ability - do it yourself, otherwise it'll cost you a pretty penny.

Going with a secondhand gearbox you don't know what you're getting.

Im also thinking of relpacing my Gearbox and diff actually :S

I sell bearings so i can get the gearbox bearings pretty damn cheap and i can get syncros at a decent price as well.

but....

i cant do it myself and also i heard that the R33 Gbox has stronger syncros? but the pull push conversion can be pricey?

also a R33 diff fit a R32? 2nd hand or aftermarket?

cheers

just as an aside, that gearbox price is wrong.

it's more like 3400
