A bmw friend of mine has a spare zf320 5 speed trans and collins makes an adapater kit. I have not found any info on if this fits in the is300 though. Collins makes it sound like the shifter works and no trans tunnel issues and I can just use an e36 clutch kit on their flywheel. Anyone have any info on this swap? Seems like the zf320 is pretty common and holds 600 ftlbs.
