Seeing if anyone knew if the R34 Neo 5spd manual transmission will work on the R33 RB25DET?....I have an S13 right now with an RB25 in there and had the stock R33 5spd, but it gave out and cant find that many R33 transmissions around. Found this R34 Neo transmission that I can pickup, but wanted to make sure that the bell housing would bolt up to the back of the block without a problem and also check to see if it is the same general overall size so that I wouldnt have any troubles with the tranny tunnel or driveshaft that I had made for the R33 setup.

Thanks

either.

r33gtr or r34gtt. 250mm clutch :)

i had one in my dr30. nice box with good ratios and very smoth operation.:wub:

I am about to fit an R34 box into my 33GTSt. (Auto to manual conversion)

as T04GTR said, all you need is the gear lever and pull type clutch.

everything else bolts straight up.

Why do you want to put a r34 box in it?

Works out cheaper to put the 33 box in doesn't it? And push type clutches are cheaper....

I just got my car back from a manual conversion So just curious

P.S help me out here: http://www.skylinesaustralia.com/forums/in...howtopic=154422

I got an R34 box as it was all I could find at the time.

Push type is cheaper.

For your conversion you need the wiring harness from the gearbox up to the fuse/relay box on the drivers side inner guard for the reverse lights to operate.

For the speedo to work you need the manual speedo gear drive in the box and a manual speedo head or it may be easier to buy a complete cluster second hand.

Dont ask me why Nissan have a manual and auto speedo head, but they do.

Hope that helps.

Buy the R34 box and swap the front housings over, i just finished doing this 26 conversion with R34 box in S13 ( www.uras.com.au/democar.htm ), i hate pull clutches so used a R32 GTR housing but R33 GTst works exactly the same.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
