its definitely hella fun.. between the guys at the shop i am kinda affiliated with, there are like 3 of these things.. we haven't done a 4g63 swap in any yet though, we decided to keep the 4g61 due to the torque of the 4g63 causing traction issues.. they haul ass when done right.. if you are short on the funds though i'd go with a 1G AWD DSM, it's been proven and they are easier to work on, which, being a mitsu, you wil be doing a lot of.
