I'm looking at doing an RB25DET (got one sitting in the shed) conversion in an MQ and was wondering if the RB30 Bellhousing will fit the L28 4 Speed box to save re-drilling holes and also I'm assuming the engine won't be on a lean this way.

im not sure on this.. but why not jsut get a g box out of a rb30 patrol and use that with the rb25? 25 will bolt straight on

How hard is it to swap a GQ box into an MQ. I thought the transfer case was on the wrong side?

The elongation of holes is done when using the 4 speed box I believe.

What problems will I run into trying to get the GQ RB30 box in?
Will the gearbox mounts line up?
Will I need to swap drive shafts? If so, are there drive shafts that will fit?
Will I need to swap rear/front axles?

dont bother, your diff is offset if i'm right its just not that easy, the factory box and the RB/RD don't bolt straight in, cross member is diff etc etc.....if you want to use an RB25 (and i wouldn't) buy a GQ for $2000 and bolt it straight in.

Can you point me in the direction of a $2000 GQ?
I haven't actually bought a patrol yet. I wanted to know if the RB25DET swap could be done in an MQ.
Sounds like it will be MUCH easier in a GQ. Thanks for your help.
