Ok Nissan tech.. Im not full of knowledge on the S-chassis or the Nissan engines.. Ive been in the Mazda and Mitsu sides of the forums for a while.... But I digress..

I have an RB20 powered s14 the car got water in it and popped the block. Cylinder 6 has a nice viewing port now.. LOL I want to upgrade to an RB25. My question is : How much switching/re-wiring/re-fabing might be nessasary to make the swap?

I have basic fabbed/homemade mounts and can fab new ones with no problems. So no big deal.

I have installed engines before. So im used to the in/out procedures.

I swapped my NA engine into my T2 Rx7, so im pretty familiar with doing re-wiring..

I just had no part of the install for the 240 and like I said im not familiar with Nissan..

So any help would be cool..
