hey guys has any one rebuilt a r32 gbox???

i bought one but the front bearing had gone, so now i was going to rebuild my old one instead.

Any ideas on what the price would be just for the bearings? or should i take them out and see if i can get stronger ones for it to take the power better.

plus does any one have the belt codes for a r32 skyline ie alt, water pump, p/s belts so i can replace them.

cheers kenny :spank:

Budget about 2.5k for the whole conversion, that's what mine came in about with the custom tailshaft and other bits and bobs (new slave cylinders etc etc)

got a quote from a gbox rebuilder in Melbourne for $900 with tradein.

That means you could go through 3 rebuilt rb20 gearboxes for the price of a second-hand rb25 gearbox conversion :devil:

Yep, that's right, but if you have more power then the RB20 boxes don't last. I know someone who went through 7 of them.

haha at 7.

Currently pushing out 230kw atw on rb20 box which is crunchy. Cant decide over rb25 or rebuilt rb20. The cheap price of the rb20's make such a hard choice.

Might be a cheap price, but if it happens to a couple after that multiply those prices together & see how they compare to a 25 box :) Also gotta think, you might want more than 230kw later down the track too.

Not meaning to steal the thread but 3rd to 4th in my car grinds occasionally so I'm looking into options as well, might have to see if there are any gearbox guys out there that will offer something like that to me :cheers: I see a gearbox like a replacement engine, you really don't know what sort of life it's had & it's would be a bit shit to buy it, install it & then find out it's just as bad as what you've just taken out....so I might look at a rebuild when the time comes, but I'm annoyed that my car still won't see the 1/4 mile for a while longer yet :)

Nathan, My gearbox has been through hell and more, has been whining for ages and I still manage to get it around the track ok. The 25 boxes are extremely strong. Having said that, I have a new box with a 5sp OS Gearset in it, will be nice to drive a quiet gearbox again :)

I went through 2x RB20 boxes (one with the 20 and one with the 30), I was a bit worried about spending $1500 on a second hand gearbox but it's been fine so far. With thick oil it crunched 2nd a little when it's cold. When it dies, I'll put a proper gearset in there :(

Upgrading to a 25 box was a bloody good decision! It now takes all the abuse I used to throw at the 20 box and some more again.

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
