TBI Fuel Injection comparison.
I’ve decided to install some sort of fuel injection system on my 77 EB with a pretty much stock 302.
I have been pouring over various “builds” to see which one would better fit my application and wallet.
Of course I thought about wiring a mustang/explorer EFI setup…but to be honest I think cost wise things would not be much cheaper…and I like the classic carb’ed look.
I looked at all 4 of the major kits out there. The one I’m leaning towards thus far is Holley’s Terminator EFI and here is why.
I am only comparing the base kits…i.e. kits minus fuel systems….after looking at all the fuel systems the various manufactures have to offer….no matter what. You can build a return style/in-tank pump system much cheaper…like 3-400 dollars cheaper than what the kits cost….using better parts.
I’ve read many hundreds of views concerning these units and the gist I get is they all do the same thing performance wise…nothing really stands out. And from all the Nay Sayers out there it looks like there’s a crap ton of people with wild engine combos expecting a system designed for mostly stock/mild carb’ed motors to instantly run perfectly with little to no tweaking…I think they had too high expectations.
So the kits I was looking at were MSD’s Atomic EFI, FAST EZ 2.0, Holley Terminator EFI, and Edelbrock’s E-Street EFI.
So for starters the Edelbrock unit was out of the running right out of the gate (same for EZ EFI 1.0). This unit cannot control ignition timing which for me is key for a daily drivability….sucks too….because I think out of all the them the interface for the system(7” blue tooth tablet..) is the best on of them all.
FAST EZ EFI 2.0
COST: Approximately $2296
I like the look of the unit and completeness of this kit as well as it has the better interface than the other 2 that are left. What put me off was the higher cost and the fact to take advantage of the timing control you need to use their proprietary (and expensive) dual sync distributor…..you could also use a MSD type distributor but the instructions require an ignition box as well….thus further increasing cost (If installing from a stock setup.) with the Dizzy + phase able rotor and box you will add over 600 bucks easy to this set which tips this unit over the wallet limit. If you already have an MSD Pro-Billet Dizzy with an ignition box this kit is a strong candidate. For my setup it would be cost prohibitive.
MSD Atomic EFI:
COST Approximately $2125
I was on the verge of picking this unit up honestly what really got me was that Atomic is giving out a free 6A ignition module with every kit at the time I’m writing this. I like the look and the price is in the middle of the rest and there are virtually no extra sensors required to hook up (fuel pressure). Problem again with this is having to purchase a new dizzy to interface properly with timing control circuit so for a MSD 8579 Pro-Billet plus the phase able rotor tacks on an additional 330-350 bucks. Compared to the rest of the 4 the interface on these is least favorable amongst the rest.
Holley Terminator
COST: Approximately $2060
This is where I’m leaning. One it’s the least expensive unit and it can plug right into your FORD TFI dizzy with a simple adapter harness without the need to wire in an aftermarket ignition box. I have a TFI Dizzy lying around and I’m sure one could pick up one in up decent shape at pick n pull or a reman’d one at your local auto parts store. The interface is not as cool as the EZ efi….but more polished than the Atomic. My only real observation was it does not come with a fuel pressure sensor. It comes with the connection on the harness…and the instructions say it is'nt required….I just don’t like basically getting an incomplete kit…as minor as this omission is the low price and easy adaptability for timing control has won me over thus far.
I planned out a fuel system using decent fuelab filters and regulator, plus stainless braided fuel hose with applicable -6 AN fittings and an AEM in-tank 320 lph pump kit for approximately 450 dollars. I’m absolutely sure I could build the same kit with cheaper parts that would get the Job done for less than 350….but that Billet Fuelab 82801-1 10 micron filter assembly is sexy….
