SWAP RB20 FOR RB25 IN 1998 GTS-T - I KNOW THERE ARE ANSWERS HERE BUT HARD TO FIND

Hi All,

New to Skylines so need a few answers - I've looked in the forum and while I'm sure my questions have been answered before, but finding it hard to get definitive answers for my particular situation.

I have a 1998 GTS-T track car. RB20DET, R33 Turbo (unsure of specifics), RB25 gearbox.

PROBLEM: Hole in side of engine due to rod trying to escape. 

REQUIREMENT: Transplant later model RB25DET NEO from AWD R34 Stagea into said R32 GTS-T.

QUESTIONS: (I know some of these are simple for you Gurus but humour me, please!)

1. What are the fitting issues with migrating to RB25DET? Engine mounts, peripherals, etc.

2. Why is it an issue whether the RB25 is an AWD or RWD model? What needs to happen?

3. What other issue and solutions are there with this transplant? 

I'm sure there will be other questions I have as the discussion continues.

Thanks.

Google will answer all your questions. AWD has a diff in the sump.

This has been covered so many times it's not even funny.

1. What are the fitting issues with migrating to RB25DET? Engine mounts, peripherals, etc.
Engine mount brackets, accessory pumps/brackets, wiring loom and ecu, heater hoses, Inlet piping etc etc you get the idea. The engine itself fits fine, it's everything else you need to think about.

2. Why is it an issue whether the RB25 is an AWD or RWD model? What needs to happen?
Replace AWD sump/diff with a RWD sump.

3. What other issue and solutions are there with this transplant? 
Google it, too much to list.

If you're trying to transplant the whole 4wd system just buy a GTR.

Cool. Thanks Jordy32. Can you point me to a previous link/topic then? It should have everything I need.
