I did the swap with my bestfriend we did it in about a day or so. I mean, if I wouldnt have went to boot camp all would have been done in a day.
Seriously, the hardest part is drilling a hole (if you have to - cable trans).
Advice: Get a good clutch, if you are converting from at-mt you are performance oriented, why not start good here? If you have a cable trans, make sure to get a BRAND new clutch cable. They stretch over time and if your car is a cable trans, its more then likely already stretched. Try to get all mounts and brackets as well, make it look good while doing it.
You may also need a Manual ECU for your car, if you are keeping the stock engine/trans, otherwise make sure the ECU is for a manual. You will get CEL if it is for an Auto.
You could also get a Manual Gauge Cluster, to keep the "not swapped" look, the main difference. The manual cluster will not have prnd21 on it. It will just be blank where these letters/numbers are. Also, the manual cluster may have a higher RPM redline than the auto.
Im pretty much out of things to say right now.
