Just wanted to start a thread about this swap. My swap was necessitated by blowing my motor. I found a cheap k20z3 motor and tranny with low miles for 2k. Motor mounts are exactly the same at least for 02-04. I have swapped the VSS sensor on the tranny. Local machine shop drilled out the hole for 40 bucks or u can buy an expensive large drill bit that u will never use again. There is a detailed post on this site on how to get the sensor to work. Just a tip if u try this, if u take the case apart to get the speed sensor gear on, make sure u put the reverse idler gear on the right side up. If u don't, when u get it all back together it will be stuck in reverse and u won't be able to get the gear selector back in. I have swapped all original sensors from my k20a2. some are the same but swapped them all just in case. I will post more info once i get everything put back together.
