I have installed an R34 gearbox in a R33 works fine but the speedo sensor in the R34 is in the diff.

There is a blanked off input on the right rear of the gearbox with a worm drive visible in there.

Has anyone put a drive unit into the R34 gearbox in to get the speedo working on a R33.

Cheers.

Question? Is this an ex-auto car? Is it or was it an NA?

Look closely at this image. On an R34 RB25DET gearbag, the speedo sender is located just behind the centre plate, low on the right side, just forward of the mount. Same as R33. The photo is of an R34 box.

Let me get this straight.

The speedo sender you want to use comes out of an auto. ?

The gearbox you want to poke it into is an RB25DE manual from an R34. ?

If so, this is the same gearbox (basically) as VL RB30, R32 RB20DET, etc, and is in no way similar to either the Nissan autos or the RB25DET manual. So it's not surprising that you can't make them work.

    • As GTS mentioned, it takes a bit of faffing, some fiddling and a little modifying.  With the strainers, you can buy different styles. Some sit flat on the pump, some angle down.  Here are some photos of mine, ignore the ugly welds lol. 
    • The smart thing is to actually locate the pump at the right point down the hanger, so that the strainer can stay sticking out at a right angle, but near the bottom. This is the perpetual hassle with retrofitting any different pump to the factory hanger. Some just go where you need it to, some need fiddling and faffing, and modifying of stuff.
    • Some updates. After a lot of praying and some inspecting of crank threads, we've found that they were both kinda munted but nothing seemed terminal. The other option was drilling and helicoiling the crank. That is obviously the last option so we decided to at least try to get a OEM GM bolt in to GM Specs. So after honing/linishing the balancer from it's .002" interference fit to a .0018" to .0015" to .0013" it eventually slotted on to the crank. ATI state the interference is nominally 0.0007-0.0009... so it's still snugger than ATI reckon and explains the issues we had to fit the thing to begin with. New GM bolt went in at 37 ft/lb then torqued 140 degrees after which was EXTREMELY   but it tightened up to 140 degrees and it was a lot of force. So all things considered, the balancer is secured to the exact specs that GM want with the OEM Stretch bolt, (that ATI say you can use..) and the balancer itself is seated and snug AF. So WOO. Engine is now back in the car with lots of swearing. Bellhousing bolts done up, driver side manifold is on, AC Compressor and hard lines are back on the car. Next step will be to connect various engine bits/wiring/intake/radiator etc. Then oil and coolant and ... test start it? And of course, looking into this issue... which actually doesn't look so bad - It looks like it can be twisted back into shape with a set of multigrips. Anyone wanna buy my bonnet? Boy it looks good over there and sunk cost sucks.
    • Also this may be a stupid question, but how would you recommend getting the strainer on a downwards angle ? as they tend to obviously clip to the bottom of the pump which usually sits level 🥴
