My setup is a MegaSquirt 3X (MS3X) which allows for sequential fuel and spark.

Fuel is an Aeromotive phantom in tank pump running to a 383 Torker intake that I added injector bungs and rails to, topped with a 1200CFM Accufab 4150-style throttle body.

Spark is eight junkyard Chevy LS "D585" coils taken from a Yukon.

Cam signal is a Jeep cam position sensor w/ adapter (sold by a Moparts member) to fit where the distributor used to live. Crank signal is a 36-1 trigger-wheel welded to the stock crank pulley with another Jeep sensor. Together, these two sensors allow for full sequential fuel and spark.

I did the EFI conversion about 5 years ago, and it has been flawless ever since. It was a challenge to figure out and piece together (especially modifying the intake), but I think it will be even more worth it with the turbo.

Having had a conversation with a fellow Moparts member about this recently, I suspect that a Holley Sniper X-Flow throttle body system would be almost as capable as my system for quite a bit less money and, more importantly, a tiny fraction of the effort.
