supercharger 4.0

So does any one on the forum have a supercharger 4.0. I plane on making my own set up with a supercharger off of a 3.8 Thunderbird. I am using a 99 XJ intake manifold and part of the lower manifold off the Thunderbird to make it work. The Thunderbird supercharger should work.

thats going to be a lot of work. there are a couple companies like RIPP and Avenger that make kits. no one on here has made their own supercharger system. Air Sierra made his own turbo setup on his 2.4L though.

you're going to need some sort of piggyback computer and a dyno to get it to work right!

I know some have taken the ECU from the 2.5T cars and wired them up to non-Mopars to power their Ford 2.3T. Why not get the T-bird ECU and wire it to the Jeep's 4.0? I doubt the 0.2L difference would make much difference. Plus I know they make tuners for the Ford EEC-IV and OBDII ECU's, so just tune it with a WB O2 and go from there.

My question though, how similar is the internals of the 2.5T to the 2.5 in the Wranglers? Would the forged pistons swap in? I imagine the mounts and such of the FWD turbo engine wouldn't allow you to just drop it in to the RWD.

There is a company that makes a supercharger kit for 2 different engines. There called Ripp Modifications. There centrifugal S/C as apposed to roots style. Basically a belt driven turbo.

http://www.rippmods.com/Supercharger..._CARS_s/20.htm

Hope this might help someone who is looking for a S/C setup.

To get the same performance at 10,000 feet as you can get at sea level...
There is a very substantial difference.

Enjoy!

I missed the supercharged part at first glance.
I figure a simple question needs a simple answer...

Enjoy!
