Im thinking of swapping a usdm 2jzgte with r154 with extension from my s13 into a sc300. ive read articles on the aristo engine swap but what is different about the usdm wiring harness? also i had to convert my oil pans to the aristo ones for the s13 do i need to switch them back to the usdm pans?

 

the sc300 is a rear sump oil pan, the s13 is a front, so yea you need to swap oil pans and pickups, wirings wiring, you need to make the aristo hanrness mate with the usdm chassis... pretty simple lots of threads already on how, i would take the custom drive shaft you have now and hav it extended and have the appropriate flange welded to match the sc as well...
