Ok here is somethin i do last nighet when imsomnia attacks,
Went downstaresand start mocking up the engine tranny combo,
If you are familiar with Nissan u must know SR20 block castings are different from FWD to RWD
But u can use the FWD one in RWD with some modifications but you cant do the other way around!
Here is what u need to trim from the FWD block to make it fit on the RWD tranny,,,
You need to trim all that to get the RWD starter on its place,
Then in order to atach the tranny on that side a heavy duty bracket need to be fabricated, and that bracket is bolted to the side of the block and goes back to the tranny bellhousing under the starter, this bracket must be minimum 3/8 thick steel or 1/2 inch aluminum,
It will be cool and super strong, this way any SR20 block could be used and i dont have to be obligated to use the ABUSED RWD blocks only!
Pss
By the way those mods is only on the starter side cuz the other side it a prfect fit!
