Haven't tried it but they're very similar and I wouldn't be surprised if it all fitted fine. Why not just buy a stuffed SR20 box, throw the gear set in and then chuck the rb20 bellhousing onto the sr20 box as they're interchangable.

I just put a SR20 bellhousing onto a CA18 gearbox I had to use in my brother's SR20 180sx.

I think the SR box is about 20 mm shorter than the RB20 box. Might want to do a bit more research?

If people can run a RB20 bellhousing onto an SR box I cant see there being a problem. I havent used an RB20 bellhousing on an SR20 box before, just heard of other people doing it. I've been told the CA18, SR20 and RB20 boxes are very similar and bellhousings interchangable.

do it brisby. :rolleyes:

in fact justin is out of town for 3 weeks. pop over to my place and we can go down to the basement and whip his box out and swap it with yours. lol, he hardly ever gets to sixth anyway so as long as we leave his gear knob on there he probably wont notice for a while...

So does that mean an S15 box will go behind an RB20?

Couldn't tell you for sure, but if people can put a 5 speed behind there S15 SR20 then I can't see why not? Might need to change the tail shaft? The standard S15 6 speed isn't exactly a very strong box though.

Yeh, but i am a tight ass so am pretty kind to mechanicals when i drive my car, so would hope i could get one to hang together. Still trying tpo do some numbers on the OS Giken gear set and also on PPG box, though ongoing maintenance is my main concern with a helical dog box from PPG. LOL i am easy on mechanical parts but hard on panels :)

      R34 Gtt Wheel Offset Advice

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
