The real beauty of this CJ.............. This stand alone can be had for cheap.

The megasquirt could be the best upgrade for any NA. It would allow for many future modifications................
The dilemna with any NA conversion, modification was the ability to control timing, fuel etc....
You can slap superchargers and whatever into an NA engine (although there are much better things you can do if you start with a turbo block).......... in the end you need the ability to fine tune the setup.
AFPR, massaging the stock motronic, extra injectors and band aiding it all will only lead to one thing.
BOOOOOM.
The 83' will have some other issues (fabricate a number of things) but you can't go wrong with a turbo block. Many fuel/timing maps out there to get you started..........after that is a lot of tuning. But thats half the fun.
On the 86 everything bolts on.....just a hand full of differences.
If I had an 83 I would look at putting the turbo on the passenger side. YOu would need a number of modifications but worth the hassle.
I mapped out the complete wiring for this setup ......it basicly plugs right into the stock engine bay plug. Quite happy about that accomplishment.
