hmm, you'll not only need the obvious parts such as the transmission, wiring, possibly the ECU and more but you'll need a manual transmission engine mount too. There is a difference between the auto and manual mounts.
for our cars are shaped differently due to the 2 transmissions. The automatic transmission is slightly larger than the manual transmission. You might need a new Intake
, you might not.
There were a few guys on nc.org that have done this btw.
