i don't know the answer but there the same engine block so bolt patterns the same if you have the torque converter/flywheel of the det you should be able to make it fit,have you checked the numbers on the boxes/do they look different ,it maybe worth posting it in the tech section somebody might have done it the other way around,or check skyline australia they seem to have done it all before skyline arrived here

There is 1 problem I know of..... The R32 uses a speedo cable, any 25DET box will use an electric sensor. You can modify the 25DET box to make it accept a speedo cable quite easily from what I have read! (google it for specifics, I'm not 100% sure :) )

I haven't done a conversion like that before so I'm not sure if there are any other problems, I don't think there will be though, the bell housing bolt pattern is the same and pretty sure the drive shaft and crossmember are the same too!
Someone will correct me if I'm wrong though :)
