EFI Question

[MoparManiac2000]

Lurker here that after many years finally made a profile. You all are of course A body focused but are the best Mopar/Car forum community around! I asked this in For trucks only but I am gathering opinions.

I have 77 D100 truck with an 318 2 barrel carb. I am dead set on an EFI setup. I understand (thanks to you guys) that it's not plug and play but will likely require a fuel system, re-wire and some engine modification at the least to be done correctly.
I am not particular to this truck and equally like the later rams that came with TBI and magnum engines (88-93).

Considering the time, money and parts commitment would you all just sell/trade for a later truck that came factory with this system if you wanted and EFI truck/car? Like I said, this is just in regards to setup, not that if you prefer the 70s trucks over the 80s/90s ones. I would likely use a Holley sniper or FiTech if I kept the 77.

In my experiences putting FI on an older vehicle is not all that cost prohibitive you just have to be very attention to detail oriented, Being a younger man you will probably pick up the ins and outs of FI quicker than most of us older carburetor guys. With that being said 70s, 80s, and 90,s rams are all nice looking and lend themselves well to hot-rodding so I don't think you can go wrong with any of those decades of Rams. I would say the deciding factor for me would be availability of trucks and parts, newer years being more readily available. good luck to ya.

Appreciate the post. I have tried with Carbs but I struggle with it. I know people say it's simple and all. I dunno, I'm a diesel mechanic by trade so Electronics and FI just make more sense to me. And in my opinion, early FI found on a Magnum is very simple, but yeah. Thank you.

If you just want a Dodge truck with EFI and not this specific truck with EFI, it's likely to be more cost effective to sell or trade for a later truck that has a factory setup. Of the setups you are considering, I would say Sniper 2 is better than FiTech, though I also hold the view that the jump from TBI to multiport is as big as the jump from carb to TBI.

If you decide you want to keep this truck only make it EFI, have you considered swapping a complete Magnum engine?

...and if you chose to go EFI with it, then you really ought to rework the truck's electrical system to support it.

got to ask your self if a stock efi dodge truck all you want or do ya want more outta it? if ya want more go sniper!

Ive used a gm tbi, fitech and an old holley projection. All were disappointing. Only way I would do another efi swap was with factory magnum stuff. Super reliable and better performance than any tbi.
Cheap also. just buy a rusted up ram for a donor.

 

[MoparManiac2000]

Thank you all. Like the one said, it would be a magnum swap and then updating the wiring. Thank you for giving me some ideas to consider

If you want "much" more over stock EFI performance, then aftermarket is the way to go and once you do that, it doesn't matter if you're putting it in a lawnmower. So if you're going for any kind of performance, stick with the truck you have. The Holley Sniper seems to have a better rep than the FITech.....at least "around here".

The newer efi trucks, (magnums never had tbi btw they were all multiport, the early tbi efi engines were all roller LA) come with lots of their own problems. Earlier trucks are simpler and respond well to efi conversions. A magnum efi swap is simple and if you use the magnum accessories the alternator gets a natural upgrade. If you use the PDC from a doner truck the wiring is very basic. I wouldn’t do ANY tbi swap, and that includes the aftermarket setups. The fuel system for any of them is pretty easy, there are many in tank or inline pumps that’ll work and a regulator is no big deal. If you use a pump from a newer magnum truck the regulator is on the pump so only one line is necessary. The downside to stock efi stuff is limited (not completely) tuning options but there are guys that tune Jtec stuff.
