I got to 12psi with just water injection and it seemed happy enough. Then I thought I hurt it so I took it apart - it's fine.

What made you think you hurt it? up

plugs were all nasty, from previous intake gasket leak and I rented a borescope and I thought it looked like the pistons were detonated badly (so did others on here). It was just some carbon build up (the engine was just the engine that was in the car, not a fresh one when I boosted it)

Let's hear more about the fuel and spark control.

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.

If done 5 years ago, how come not a dual sync dizzy? Once you buy the 2 sensors, adapters, and outfit them, I would think you're pretty close to the price of the dual sync?
My classic FAST is seq capable but I don't run it. Done in 2009 there weren't was many options and it didn't seem like the $ and effort would really effect the quality of life with the car. I did pick up a new but discounted MSD dual sync dizzy along the way, but haven't used it yet. I have a lean burn one that I re-indexed.

I had looked into buying a dual sync distributor, but my research at the time found nothing positive to say about them. The crank sensor eliminates any variation in timing due to chain slop. Also, with the individual coils, I didn't want a distributor and cap simply taking up that space.

The Jeep cam sensor and adapter is a no-brainer... it literally drops in with no effort. The crank sensor on the other hand was a bit of a thing. Its the only part of the whole EFI project that I needed to take to a machinist to do, but it was something like 1 hour of his time to perfectly align and center and weld the wheel to the pulley. Total cost including all parts and the machinist was something like $200. As a percentage of the total EFI cost, it was not much. The sensors are common replacement parts that (theoretically) can be purchased from anywhere.

Does it make a difference in performance? Honestly, I just don't know... but it looks really clean, and I like the individual coils.
