3L turbo Posted July 25, 2012 Share Posted July 25, 2012 G'day I've recently been given what I've been told is a manual transmisson out of a rb20 I'm just wondering how can you tell the difference between the turbo and non turbo box? Or if there is a difference between them? I've looked everywhere on the net and can't seem to find any information on it. Thanks in advanced, sorry if this has already been covered in this forum.

Hanaldo Posted July 25, 2012 Share Posted July 25, 2012 There is no difference, RB20DE and RB20DET are exactly the same and are pretty much the same as an RB30E gearbox as well Link to comment https://www.sau.com.au/forums/topic/405522-how-to-tell-the-difference-between-a-rb20-non-turbo-to-a-rb20-turbo-rwd-manual-gearbox/#findComment-6458443 Share on other sites More sharing options...
GTSBoy Posted July 25, 2012 Share Posted July 25, 2012 And RB25DE box is also the same. But the ratios are not all the same. When I put RB25DE box into my R32, it was noticeably different gearing in 2nd and 5th. I'm pretty sure that the RB20DE ratios are the lowest of the lot.

3L turbo Posted July 25, 2012 Author Share Posted July 25, 2012 Ah too easy! Cheers for the help, been searching all morning and couldn't find nothing lol. Actually, what kind of power can they handle? My gearbox I got now behind my rb30 has crapped itself and I got this box just as a quick fix for the time being, I've got about 230 rwkw, how long do you reckon it will survive for before im back To square one?

Unless it's out of an R33 in which case it will have an electric speed sender Link to comment https://www.sau.com.au/forums/topic/405522-how-to-tell-the-difference-between-a-rb20-non-turbo-to-a-rb20-turbo-rwd-manual-gearbox/#findComment-6458553 Share on other sites More sharing options...
GTSBoy Posted July 25, 2012 Share Posted July 25, 2012 But I just pulled the R33 sender out and poked the R32 cable in.

GTSBoy Posted July 25, 2012 Share Posted July 25, 2012 No. R33 RB25DE box is the same same as the R32 box (in the speedo hole). The electric sender in the NA box is not the same as the electric sender in the turbo box. No need for Navara hybrid drives. Just pull out original and stick in R32 cable. As far as I can remember, anyway. Was 7 or 8 years ago.

As far as I can remember, anyway. Was 7 or 8 years ago. Oh you meant that. I thought you were joking lol. I've never swapped the N/A 32 vs 33 senders, only turbo/navara mod ones. (I am fully aware the senders turbo vs n/a are different though) Link to comment https://www.sau.com.au/forums/topic/405522-how-to-tell-the-difference-between-a-rb20-non-turbo-to-a-rb20-turbo-rwd-manual-gearbox/#findComment-6458849 Share on other sites More sharing options...
GTSBoy Posted July 25, 2012 Share Posted July 25, 2012 I did it when I killed my RB20 box and couldn't get one at a sensible price.....yet no-one wanted the R33 NA ones....even though they were the same. The R33 one I got was almost completely brand new. Was a good deal.

Cheers again for the replies they can handle a fair bit of power, its the torque that kills them, because your putting whats ment to be for a 2000cc engine onto the back of a 3000cc engine it wont last very long especially if you have a HD clutch, that bitch will die fast as f**k if you like to put your foot down alot and if you take off in the wrong gear you gonna snap all that shit up in there lol your best bet is to spend that extra cash, get yourself an RB25DET box and tailshaft, get the tailshafts glued together by a workshop, and V-WALLA!! a box that will handle the shit you put it through Link to comment https://www.sau.com.au/forums/topic/405522-how-to-tell-the-difference-between-a-rb20-non-turbo-to-a-rb20-turbo-rwd-manual-gearbox/#findComment-6463793 Share on other sites More sharing options...
3L turbo Posted July 29, 2012 Author Share Posted July 29, 2012 Thanks mungy for the feedback. I recently found out a couple bearings in the box I'm gonna use have collapsed, drained the old oil out of it and a fair few hunks and chunks came out with it, instead of playing around with that might look into adding some cash and picking up a stronger box, seeing as I'm gonna through more cash into some more horses, I'll end up at square one lol?

mungy Posted July 29, 2012 Share Posted July 29, 2012 trust me i ran a RB20 box in my RB30ET and killed it first week i had it, bought a second hand one to get me around while i saved for a 25 box and blew that the next week borrowed some cash for a 25 box and shaft, had no troubles with it to the day i sold it Link to comment https://www.sau.com.au/forums/topic/405522-how-to-tell-the-difference-between-a-rb20-non-turbo-to-a-rb20-turbo-rwd-manual-gearbox/#findComment-6464452 Share on other sites More sharing options...
3L turbo Posted July 29, 2012 Author Share Posted July 29, 2012 Yeah true that, I'm not that keen to keep changing em, takin one out was enough for me lol. Thanks for the advice mate!
