Ok does anyone know how to differenciate between the RB gearboxes. EG RB20, RB25 R33 S1/S2 etc. Want to do conversion to R33 S1 turbo 5 speed in my DR and need to know what I'm looking for. Also is there any differences between turbo and non turbo R33 5 speeds??

Thanx, Vaughan.

rb20/30 and 25 de are all the basically the same box , phisically smaller than the 25det

33 s1 and s2 are the same box , 34 is basically the same box . externally can be spotted by extra webbing on the case . internally the same with different ratios

any 25det box will be the best to get

Yeh thanx MrMayhem, from what I've learned it's basically a case of slotting top 2 bellhousing bolts and a new g/box x-member and tailshaft right. I need the S1 cos it has a mechanical speedo output whereas the S2 is electronic.

Quick semi-related question. I have a little badge on my gear stick dash surround that says "Super Quick X" with a serial number -- looks like some kind of gearbox part ID plate but I have no idea what it's for and if it's standard? Any ideas? Oh It's on an R33 GTSt S2 ('96).

all 33 det boxes are lecky

levinet sounds like a phone number to a brothel give it a call

take a look at the shifter either from under the car or takign the console out and shifter boot off might find its a short shifter

Haha, funyy. But anyway, it's not a short shifter, everything seems normal... I'll go take a picture...

Ok, here we go, sorry about the camera phone pic, my DSLR is too much of a hassle to take out for a quick snap:

    • 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.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
