What sort of info are you after?

A couple of things come to mind. The under dash plugs are different between early and late model r32s so if you have an early model Car and a late model front cut there will be some rewiring required.

The brakes would need to be upgraded.

The DE cross member can be used. Worstcase the DE engine mounts on the DET would solve any problems.

Used your DE powersteering and AC pumps to save you having to remove them from the car, Change the bracket on the block if needed.

Gearbox and tailshaft should be alright, same lengths etc.

Does the DE have an LSD?

You will probably need to cut a couple of holes for IC piping.

Tail shaft between auto and manual's is different. If your going from auto to manual you'll have to get one shortened. Gear box cross member is differnt

GTS and GTST axles are different, so if you swap to the GTST LSD you will need the shafts from the GTST as well. The GTST uses a 5 bolt star pattern for it's shafts, I can't remember what the GTS uses but I do remember they are different. Ran into this problem on a rearend swap once before.

I'm not sure on the cluth plate sizes, I know of two different diameters, a 225mm and 240mm. I've seen both on RB20DETs and DEs. The 240mm seems to be more common and is the same diameter as the RB25DET. I 'think' (not sure mind you) that the DE used the 225 as this was the same diameter that the R31 RB20DET used. As long as you match the right flywheel with the right clutch diameter there should be no dramas, although the 225 might not hold up to a later model, more powerful RB20DET. I had one in my 89 and I could make it slip just by thinking about it.

yep, RB20de flywheel is different to RB20det, 25de, 25det,

Best to get a RB20det flywheel and a new clutch to suit.

check welsh plugs in engine, you might want to replace them now. and timing belt

otherwise everything should fall straight in hook up and start

will my GTS box b alright i aint planning to do any major dragging or andything like that until i get the money for a GTS-t box also will my non LSD diff work fine plus regarding petrol pumps will the GTS petrol pump be fine? and do u have any pics regarding doing this swap or know any one who has done this before?

Thanks again guys

[mabru]

I think the boxes are pretty much identical, but I would go with the GTST or better yet a GTR fuel pump. The non-LSD diff will work fine.

any body got info on swapping rb26dett into r34 gtt?

[Baba]

do you have any info on how to mount and install the standard intercooler or would it be much easier to go straight for a bigger intercooler mounted in the front behind the bumper.????

Thanks for all your help guys greatly appreciated will keep you all posted on project.
