This is a cool build. When I decided to go efi it came down to the megasquirt and a self learner. I went with the msd atomic for ease of install and tuning, but if I do another I will go the megasquirt route.


08 WK bone stock
00 WJ daily driver
99 TJ mostly stock 97 TJ cheap jeep
81 CJ7 very little stock
60 CJ5 tore down

I might suggest you nix the AMC 4 cyl, and go with the Iron Duke instead.

Had I known then, what I know now, I would have been tempted to drop a Turbo Coupe engine in my CJ5.

Putting the EEC-IV controlled Ford 5.0L into my CJ5, I learned more than I ever wanted to know about EFI.

I am not interested in any engine swaps. I am keeping this jeep as original as possible.... aside from the obvious.

I put a 5.0 EFI mustang motor in my last CJ7, so kinda been there done that type thing. Although that was a SWEET set up. Lots of power, very reliable, got around 20 mpg, ran nice and smooth. Loved it, wish I still had it. Like an idiot, I sold it.

On a positive note, I have another cj7 that will have a 5.8 EFI in it. Been collecting parts for that for a couple years now (just scored a couple nice hard doors for $200). That project will be a major undertaking as that will be a full tear down and restore.

Well my project is somewhat at a stand still on my end. The block, crank and head are dropped off at the machine shop. He is about 3-4 weeks out. However, he is going to get me the bore size and deck height next monday so I can get pistons ordered. Other than ordering electrical parts, reading up on EFI, and tinkering with my engine stand I have to sit on my hands for a bit.

Quick suggestions on the 5.8 EFI.

What year is it? The speed density straight up sucks. The MAF system is far superior. I would recomend you use that sytem vise the speed density. Way more tuning options and the ability to push considerably more power. I did EEC4 in one of my previous jeeps and It was awesome. About as easy as any EFI. I've moved on to LS based motors now though.

Its a 95. I will most likely be using the Magasquirt. One of the big reasons why I am doing it on this little 4 banger, this is a good practice engine. I wouldn't touch that speed density EECIV stuff with a 10 foot pole. The 5.8 will most likely be built up. Already scored some decent heads for it, zf5 speed and a few other odds and ends.

I used the mass air on the 5.0 HO In my last cj, but I never got into any tuning cause it was a stock engine. It was a easy hook up though.

Got my efi intake today. I think I will try to find a 4.0 throttle body for it. Somebody put a rediculous silver paint on it for the pictures.

My relays and fuse panel I will be using. Planning on putting that sealed relays next to the battery where the old service port was and then putting the fuse panel under the original fuse panel under the dash. I need to find out though if that will create to much electrical noise running wires that far and near other wires.

Anybody know what proper crimper these connections take?

anybody know of a good turbo forum so I can get some of my turbo questions answered.... Like how to hook up my brake booster and pcv valve?

I have a WRX STI, 2.5 turbo, maybe I can help?

Well still waiting for stuff. My head is cracked, pistons are being made, rods are ordered, block is done, crank is done, rebuild kit is here. Life got in the way, so I havn't gotten to do much else to it.

Back to working on a few things. I was never able to locate just a head, so I picked up a whole running engine. I took the head off and will drop that off at the machine shop tomorrow. In the mean time, I think I am going to take my cracked head, mock it up on the engine I just picked up, so I can start getting all my wiring and fuel lines done on the engine run stand. If the head has a non water jacket crack, I may even try to start this motor with the EFI. Either way, I have decided to get the efi up and running on this engine. that way when I have my new motor done, it will fire up instantly and break it in properly.

Well didn't get as much done today as I wanted. Got the junk head sitting on it. Unfortunately it has no valves/springs so I cant use it to start the engine. I did however get a couple trays mounted for the battery and gas can. I also got the fuel pump mounted and started working on the control panel. Found a couple gauges I had laying around, as well as a couple switches. Hopefully tomorrow I will be able to start getting the EFI, relays, fuses mounted, start mocking up wiring, get the starter wiring on it, and fuel lines. I realized today I don't have any injector connectors so I need to get some of those coming.
