[IMPALA LUEE]

i have a 01 impala 3.4 v6 but i want to changed it to a 3.8 series lll supercharged. i want to know if i could use my same wires and computers, or do i have to change the wires and computers as well, or what kind of modifications do i have to do. also do i have to upgrade my trany or use the same one, or what can i do, what trany can use to upgrade my 01 impala. any suggestons thanks

IIRC the wire harnesses are different, i know the pcms are for sure, but thats an easy fix w/ a power tuner (or similar) the main diff between the trans is the diff, sungear, output shaft/axle (pass side only), you can buy the upgrade kit from the usual places, but being an 01 (assuming higher milage) you're better off getting a full build from someplace like www.tripleedgeperformance.com
honstly w/ an 01 3.4, youre better off keeping it as a DD and buying a newer one, either a SS or one w/ the 3.8 already in it

Agreed. Too much work, much easier to buy a different vehicle with what you are looking for.

the top swap on a 3.8 wasnt bad >$1000, and a weekend's worth of work, but you'll need someone to prog your PCM
