every little thing is different, it sucks.I find it funny that they don't have this kit for the LeSabre although it is also the same 3.8...

ya the gtp comes supercharged with an eaton m90 supercharger....also if you plan on twin charging get ready to do some research...because tuning something like that would have to be a nightmare...also make sure the turbo and superchargers boost isnt an eratic change from maybe 5psi then to like 12 psi because driving that thing would be another nightmare....i say buy a bigger pully,injectors ,fuel pump and some engine manegment and call it a day...or just get another car thats just my .2

Yup I finally got it , thanks Highroller
V6 lateral engine, wastegate is tapped on the backside exhaust bank, upstream of the turbo, boost control could be erratic...
This kit is acheivable home made I think, for a lot less.
But if you go this route, just ensure yourself to have suitable engine/fuel management.
Good Luck
