Hi,

As topic states;

Can anyone do this in the Sydney area? If so, please point me in the right direction.

or a step by step tutorial?

The box is going back into a 4wd chassis.

I was going to gut the transfer case and get it welded shut, but apparently it's not as easy as this, so any help appreciated.

thanks

Do as Brett said. Even better, run a switch (and a relay, maybe? Never needed to do it, so not quite sure) and have the option of RWD or AWD.

Switch isn't possible at this stage. I dont have a front sump/diff to run front shafts!

Ive got a gts4 without the motor. It Came with a gearbox which is gtr.

I bought a rwd rb25det to drop in and now need the box to be converted to rwd only.

Thanks for the replies thus far, i hope you can understand my predicament

r32-25t

RWD gearbox requires modding the 4wd crossmember (adding some height to it), as a rwd gearbox crossmember won't have enough width to span across the chassis.

The diff stub will also need to be changed to suit RWD tailshaft. (4 bolt instead of GTR 6 bolt allen key)

The above will be my plan B, but It would be a real pain, as i would have to fork out extra cash for a RB25det box, whereas the GTR box is essentially a longer version of an RB25det box with the transfer case and longer shaft.

Scotty,

Early GTR gearboxes run a spline or floating type front shaft, not flanged like the Stagea's (i forget the terminology, . Therefore, no front shaft= transfer case oil everywhere.

I read that some people have gutted out the transfer case but have left a few things in it to keep it going. The hole where the front shaft once went in was then welded shut.

Anyone with more insight?

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
