scott77, I'm busy using a SR20VE and a S14 gearbox.

Motor is mounted in a 1200.

From my Build Thread:

One of the biggest challenges right from the beginning of this motor and gearbox combination was the alignment of the bell housing bolts, if you take the standard motor and gearbox, only 4 bolts on the right hand side is in alignment, this meant I had to make a adaptor plate, something I was not looking forward to. Rezlo advised me to use the RWD upper oil pan from the S14 SR20DET motor. After sourcing one it quickly became apparent that this is the way to go as know 8 bolts was in alignment, 4 on the right and 4 at the bottom, luckily the 4 most important bolts on the bottom was covered.

Anybody else considering a conversion like this, here is a picture of the SR20DET RWD flywheel and the SR20VE Automatic flex plate. The ring gears is exactly the same. The reason way something like this was of interest to me was the fact that I’m planning on using the original FWD started mounting with the RWD gearbox. Main reason for this is that I can keep my block original and use the FWD starter that I got with the motor. Only problem with this is the fact that you need a expert to remove some material from the outside of the flywheel to get the FWD starter to fit over it, also a smaller pressure plate need to be used with the FWD flywheel.
