Not sure if you are aware, but the kits can no longer be bought new. These were sold by B&M and Mopar Performance (Direct Connection before that), back in the '80s. You'd have to find a used kit like the one I sold on Ebay if you want one.
Having said that, these were made for carbed cars only, not TBI. In their stock form, with the stock 5 psi pulley, if set up properly they could make a stock carbed 2.2 run about like a T-1. Benefits were it was a super easy conversion, no electronics, no FI, no wiring, just bolt it on for the most part. They made lots of instant torque, much like a V-8. Downside was that wheel spin will cost you ETs. But it sure is fun
Though there was some hood clearance and tensioner issues they were a really neat setup if that's what you were looking for. If you do a search in this forum you will see those issues outlined. There are guys running them now with a simple pulley swap that I know running 7-9 PSI...not bad for an otherwise stock carbed/piston setup.
If you are looking for a kit make sure it comes with: the blower (of course), blower bolts, blower intake, crankshaft pulley, power steering pulley...gaskets can be made, so no big deal if they are missing, tensioner doesn't work so it's not a necessary (again do a search here) and belt. I ran a smaller belt to eliminate the tensioner by doing a simple power steering pump bracket mod.
They also came with a shim to drop the compression of a stock N/A 2.2, but the early manuals said you could do this by stacking 2 head gaskets or run a water injection set up instead. All in all a cool set up that looks even cooler if you can find one
