Which EFI kit?

streetstang67 · Apr 17, 2005

I want to change my car to EFI for reliability, performance, and fuel economy. Now, I currently have a 4bbl intake and carb. What kit should I get to convert to fuel injection? I can't find any kits under $1000, which seems way toom much, at least for me

To be honest, if it's $1000 complete (i.e. intake, metering components, rails, injectors, cpu, fuel pump, wiring, sensors, etc.) it sounds like a pretty good deal. Otherwise, you can do it for less than a grand using 5.0 donor parts, but it'll still probably cost you $600-$700.

If your car starts and runs well as it is, then I would say leave it alone. I have the edelbrock pro-flo efi on my 68, and it runs will and has good power, but it would take alot of gas to make up the extra 1500 bucks over a similer vic jr. /carb combo. On the other hand, if you live in a cold climate, cold starting alone might make it worth it.The reason I went with the edelbrock setup is that I really don't like the look of 5.0 setups in old cars.If that doesn't bother you then get some doner 5.0 parts and do it cheap.

take a look the holley commader 950 TBI pro-jection setup. it's a little bit more than a grand but should work nicely and you can keep your stock air cleaner to hide it, so that ca still kooks stock under the hood.

At one time I found a kit for under $700, but I can't find it now, I guess they discontinued it. Anyway, what do you think the major advantages/disadvantages of EFI are?

Better starting and better fuel economy - more efficient. That's why i'm converting my '66 over.

My project is getting in deep I would suppose... find yourself a donor car to obtain parts from.

I've spent $100 for a computer, $250 for a modified harness w/instructions to hook up to my '66, and $800 for intakes (stock), rails, inj (used), coil (ford racing), VSS & cable, a computer mounting bracket... and I still need a fuel pumpt, BAP sensor, and throttle cable + pedal. I've got about $300 - $500 in parts still left to get...

so I'll be right around $1700 or so when I'm done with her.

But - no more carb tuning for each season, it'll have a quicker response and better fuel eff. - especially since gas is $2.10 or so... and getting higher as summer approaches.. plus i think a supercharger will work better for EFI than my carb setup.

reasons to convert / disadvantages

Most people convert to EFI for at least a few of the following reasons:
Better fuel economy
Great cold starting ability
No retuning for altitude changes
No vapor lock
Computer controls fuel and timing and possibly other functions
Computer uses trouble codes to tell you which areas to concentrate on when a problem arises
Some don't know how to tune/work on carburetors

Disadvantages:
More Complex / Appears intimidating
Requires elec. fuel pump, return fuel line and high output alternator
Parts can be more expensive, more parts to go bad (parts are usually very reliable though)
Some are unfamiliar with code retreival / EFI troubleshooting
Sometimes computers need to be chipped/recalibrated if the system is heavily modified from stock ("hot rodded")

These lists are not complete but hopefully a decent start.

You might check these guys out. I'm not sure what the price is, but it looks like quality stuff. Plus it's mass air flow, not speed density like the Holly and Edelbrock stuff. Not knocking the Holly and Edelbrock units, I would just prefer mass flow over speed density.

You could spend $20 on a book and maybe $50 of parts to make your Holley work just as good as most fuel injection setups. I know alot of the EFI groupies will scoff at that statement, but oh well. Most (I REPEAT MOST) don't have a clue about carbs and think EFI is so great because they weren't willing to tune a carb. Sure all OEMS use EFI, they have their place in an emissions friendly, poor climate, yuppie based world. But seriously, try to get your carb setup right before you give up on it. It will give excellent fuel mileage and driveability when properly tuned.

You have a good point here, carbs can be made very driveable, it just takes more work and time. Most people, like me, would rather not have to worry about adjusting a carb periodically.

point taken. But, I can rebuild and tune about 20 carb'd setups in the amount of time it takes to install an EFI system. Periodic maintenance isn't much of an issue with either. A fresh filter and maybe a can of fuel system cleaner 1 or 2 times a year. I only adjust my carb twice a year, I richen the idle mixture by 1/2 turn in the late fall, lean it back out in the spring. 30 seconds max. Its all good though. EFI looks cool and hi-tech, carbs are simple and neat. I like 'em both, but I'm sticking to carbs on my classics.

If fuel mileage is a main concern, an overdrive trans would yield a greater increase in mileage than a carb to EFI swap.

that's why I did the T-5 swap first, great recommendation tho!! heh, now just need to gain a little more MPG than what I currently have.

You walked into this one. Then buy a hybrid car LMFAO!

Sorry, I agree with 302, a carb can be very reliable if done right!
