DJ-L3ThAL, I don't quite know what your getting at??? (according to my thread name)???????
There is almost NOTHING even close to being the same between a R33 RB25det engine and a R32/33 RB26dett.
The blocks are different, The oil pumps are different, the heads are totally different, different port shape, different bolt pattern for inlet and exhaust manifolds, one has VCT the other does not, so I can't see why, being "my thread name" I should lie to skwertle and tell him there's NO difference????????
If he's talking about just a short block then he's going to need to get a block from a 4wd stagia, oil pump from a RB26dett etc etc.
Then, I think the head bolts are a different size so the block would still be different....Rob
