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.

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.

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?

Cheers again for the replies

Unless it's out of an R33 in which case it will have an electric speed sender

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.

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)

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.

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

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?

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 :dry:

borrowed some cash for a 25 box and shaft, had no troubles with it to the day i sold it

    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy. 
    • Welcome.  Was the mistake the car, or joining us? 😏
