Hi does the RB25DET have the same engine mounts as the rb30 so i could put it into my VL or do u reackon it would be to much of a tricky job? Thanx

Well ppl put the RB26dett into the 240z, with only very minnor changes to the engine mounts, so I dont think it will be much of a problem.

As far as I know nissan changed very little of the external layout of the block since the orginal 240z engine, after all if it aint broke dont fix it. So I believe the existing RB30 mounts will bolt directly to the RB25/26 block :)
The hardest job you will have will be mounting the gearbox, as I belive it will use a differnt mount, and possibly altering the driveshaft.

Then of course you have to make the big pig handle. :D :D


And if this dosnt get much more in the way of replys in a few days Ill move into the skyline forums for you, the guys there will be able much more experianced advice. :cool:

The RB25 gearbox wouldn't have too much trouble- the driveshaft'd need to be lengthened a little if my memory serves me right- I'm not too sure of the mounts in a VL- but there'd probably need to be modficaton done to them- seeing as the two gearboxes are different.

I have done this conversion and it all just bolts in! Use the VL engine mounts, and you simply need to drill a couple of new holes in the gearbox mount for the R33 five speed gearbox!
The manual tailshaft slides straight in! no mods needed.
