Supercharged 2009 G5

I was going to do a turbo build, but decided it be easier to get tuned if I did a supercharger build. I have everything I need already except injector harness. I got one off an lsj but the connector from the lap harbess to injector harness is different than the lsj harness. I would have to cut up both injector harness to make one. I was wondering if anyone has used injector connector adaptors, and if they would work good. I dont wanna ruin my harness if I wanna go back to stock. thats the only thing I need to figure out before I get started taking my car apart. ill post pics of everything I have soon and of the tear down and video of it running.

so excited I can't wait! lol

You cant pull the pins from the original connectors and install the lsj on yours?

I was going to do the same but mine is a L61 soon to have a m62 bolted on cant wait either!

Yea well I plane on splicing them and soldering the lsj connectors on. But what I meant was that the harness to harness connector is way different. And I dis not want to splice just in case I wanna go back to stock and sell the car.

I did see some ev6 to ev1 adapters but idk if they would work or if they are safe. I read mustangs and camaros run them though.

If you ever go back to stock just splice the old connectors in and put some tape over it and they will never know

Thanks. I knew he was wrong, just had to double check. I will disconnect my battery to avoid causing a short or anything of that sort as a precaution.

Already got everything installed. The belt is a bitch to put on. Had to grind some of my alternator because the tensioner didn't go down all the way. Finally got it on right now and tomorrow gotta figure out how to mount the heat exchanger. It's the stock lsj HE. After that I will wire the pump, figure out the tb vacuum line, and should be ready to flash the tune, and hopefully it will start :/

It is not as easy as people say it is to do lol. But I guess it's because of the problems I ran into.

Last pictures of the install and final product :p

The car if fun to drive even with the base tune, but going through gas like a v8 though. Or maybe I just have a heavy foot lol. wanna start datalogging but haven't installed my wideband and dont have the pillar to put the gauge in.

It does spin like crazy but I have two kills already haha . Svt focus and a chevy Silverado I was ignoring but kept insisting on running me. Beat the truck by about four, five cars lol. Focus was from going 60 on the highway and I pulled away like nothing. I'm liking the boosted life
