Hello,

So I just recently bought a rb26dett for my 1992 r32 gtst. I've been told I need I'll need a new cross member and drive shaft to make it fit, I know I needed a new shaft but didn't know about the cross member. What cross member will fit for a rb25 trans to a 26 motor? And what drive shaft would be best? I am also having trouble finding an adapter plate. Any info would be greatly appreciated

You don't need a new crossmember. The GTR crossmember cannot be put into the RWD chasssis anyway.

You just need engine mounts, and I'm pretty sure your RB20 ones will fit. If they don't google up what other people have done. It's not hard.

What gearbox are you going to use? Don't say the GTR gearbox, because it won't fit. It just won't fit. Don't even think about it. And don't say you're going to use the RB20 gearbox, because it won't survive. The RB26 makes more torque than the little box can handle.

You will need an RB25DET gearbox. And then you will need the front half of a tailshaft to suit, and then you will need to take your R32 tailshaft and the front half of the (likely R33) shaft and some careful measurements to a drive/shaft manufacturer (like Hardie Spicer) and get them cut and shut together.

There is no other way to do the tailshaft properly. Nothing off the shelf will work.

/\ You'll need to cut the diff off the 26 sump & usually grind the fins on the bottom a bit to clear the gtst xmember.

You can cut the transfer off the 26 box & use it but no point if you have a 25 box, not sure what adaptor plate you're looking for, bell housings are same

Don't hack up the 26-parts, you can sell the sump, diff and trans for a pretty penny. 

Neo RB25 5spds are still available new and you can always grab a used RB25 Trans. They also make adapter plates to run a modified CD09 out of a Z33/Z34 and you can get bellhousings for the T-56 / Magnum.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
