yeah. so my KA'd s12 blew up the hybrid tranny I was running. It was a mk2 CA20E manual box with a KA bellhousing on it. I broke a shift fork pretty violently at the last drift event, and big chunks were coming out the drain plug when I changed the oil. So I figured, why not try this s13 transmission I had in the garage on for size.
s13 KA manual tranny
front half of an s13 manual driveshaft (USDM only! JDM 180sx driveshaft didn't work, I tried this first)
stock s12 mount and crossmember and clutch slave cylinder
you also have to trim back about 2 inches of sheetmetal for the shifter, but honestly, it puts it in a WAYYYYYY better position than before (right within reach) and I can use any aftermarket s13 shifter now. And since I have no interior, I don't mind having an extra 2 inches cut out of the center console area.
but I just wanted to confirm that YES if you use the front half of an s13 driveshaft, you can run an s13 gearbox w/o any custom work or fancy driveshafts.
its sliding time!
