I'm looking at doing something similiar, I've done a number of searches in addition to reading a number of technical sites. Orignally was looking at a T3/T4 but due to siz constraints I'm curious about the t28, this was the turbo recommended by the person that referred me to this site. The Jeep is daily driven (rpms rarely above 4000). Needs minimal lag between 2-4k rpm.
The turbo will need to fit under the intake manifold (dual batteries and 2 AC compressors).
Using some of the online calculators, a gt28 with between .63-.86 AR should work. All the posts I see state a larger turbo is needed. Thoughts on this smaller unit?

front are coils-use a shorter coil. rear is sprung over, remove a leaf or switch to spring under (will lower 5-6") using lift springs or lift shackles to level the rear.

I realize the 4.0L Inline 6 from Jeep is pretty inefficient when it comes to breathing and revving, but lets do a simple break down of displacement vs. turbo sizing.
Stock eclipse engine - 2.0L with a half way decent breathing DOHC head.
Stock jeep motor - 4.0L with an obsolete head that dates back to the 1960's.
I think you need a little more turbo to get started, I'm not saying it won't work, just that your manifold will be glowing at cruising speeds because you will have her backed up with a small turbo. If you did do this it would make great torque, just not much more power and would probably fall on it's face up top big big time.
A turbo jeep with a 4.0L used to hang around the drag strip near Pittsburgh and the owner ran a 60-1 with a stage 5 turbine wheel. That is almost double the size of a Big16G It ran 12's and was reliable to the best of my knowledge.

and the front was new coils but what car coil fit on cherokee s
if not cut the coil or clamp the coil and add an airbag to stop any bouncing.. but that was my idea i dont know if there a correct way or not...Have you done this to ur jeep or u know someone who has...??
