Hey Guys,

I've got a RB25DE manual gearbox here that needs to go.

Came out of my R33 when I upgraded to a 25DET box.

Worked well when it was in my car.

Someone come take it off me before I put it in my VL. whistling.gif

All reasonable offers accepted.

Cheers,

so it has the same ratio's as a rb20det 2wd gearbox :) , i won't be able to grab it before the weekend i don't reckon mate , might be , just can't say definate (if damo is not wanting it, looks like he'd be wanting a rb20de box as they're different according to that graph)

Edited by toffy

Na see the problem is that graph refers to the rb25de that came in the late model r32s.

the 25de from the r32 is based on a rb20 and has very little similar to the r33 rb25de. so at a guess id say the ratios will be revised.

also the r32 range stuck with a common diff gearing for auto and manual models where as the r33 range changes between auto/manual/turbo/non turbo.

but thaks for the listing regardles as we have a rb20de box and thats got the ratio that may suit us better.

so i no longer need to be first in line.

    • Is it alright to top up with just another green coolant?
    • thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...
    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
