I was wondering if anyone here has done a gearbox rebuild for their RB (30 box in this case) and how hard it was to put new set of bearings thru it and maybe some syncro rings while im at it..

Any help/tips/warnings/tales-of-failed-home-rebuilds-to-put-me-off/prices-for-a-pro would be great!

Regards,

Brent.

Sorry to hijack, but may be helpful....

 

Has anyone got the part numbers for the main bearings for an r33 (push clutch- earlier?) I wanna buy the bearings from cbc....

 

Or any other boxes for that matter would be helpful to anyone....maybe syncros and seals etc?

I have been in touch with nissan .. theres about $300 worth of main bearings in there, thats with out pin rollers.

Part number for the two main drive bearings are

NI-32203-V5201

NI-32203-14360

and there are 4 counter Shaft bearings aswell, if you need those PM me.

EDIT: I forgot to mention this is for an RB30E gearbox (MF5)

Gearbox bearings for RB20DET/RB30E gearbox are available from CBC and will be in the region of $150, and most likely less (these gearboxes are virtually identical). Just ask them to look up R31 Skyline gearbox - they have catalogues that will list them. Last time I looked there was 3 countershaft and 3 mainshaft bearings.

I can dig out the aftermarket PN's for R32/R33 GTR gearbox if there's any interest.

Does anyone know the designations of the RB gear boxes, and the differences.

I am currently trying to work out if there is a difference between the RB20DET box, and the NA RB30E box.

Bearings are identical between the two, AFAIC, but R32 GTSt gearbox has double synchros on 2nd and 3rd gears - RB30E type uses single synchro on all gears. There are also some gear selector mechanism design differences.

I have recently had mine done syncros, bearings, and clutch. NOT cheap to do. This was for and rb25 5speed for a $1000 extra could buy a 6speed. Any way if 4th is stuffed then you have to replace the hole shaft as the 4th is pressed on and will be wrecked it removed

excellent :P (32GTR box would be the same as the gtst for bearings i assume?)

Do you remember if they had the r33 gtst box on file? I need the main bearings...my syncros are fine.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
