How I justified switching to EFI. Agree or disagree?

[sccacuda]

Just pulled the trigger on Holley's Dominator EFI setup. I had this monster parts list. Total was right around $5500. For that I got a DIS crank trigger kit with coils, 16 injectors (66lbs. primaries, 120lbs. secondaries), all the different harnesses and sensors, map selector, two of the huge 1800 fuel pumps with pre/post filters, 2 NTK WB02's, etc...

This would be replacing carb, ignition box and accessories and RacePak. Figure $3600 or so. Fuel pumps/filters wash for both setups, so deduct $1100. FI now $4400. WB 02's wash (need for carb tuning), so deduct $400. FI now $3900. So, for $300 I switched to EFI and gained a ton of tuning/drivability. That's how I laid it out to the wife, and the numbers make sense. The manifold conversion is the only "outstanding" cost.

Wish I had done the numbers sooner!

I bought an 84 325e and an 88 325is for less than that. I'd probably just stick with a carb or go LS for that price.

What he said. Junkyard 6.0 LS (complete) are like $1500ish.

My 944t costs less than that as well, since we're doing comparisons. :)

I think you guys are missing my point. This is for an engine management system for my Mopar, not what you can buy for that price, be it a Chevy, BMW, Porsche, or 30 Yugo's.

In my own defense, you didn't explicitly state you have a Mopar.

[sccacuda]

No problem. You Chevy guys can buy parts at 7-11. If I can find it, I know I'll pay twice as much as a comparable Chevy part.

Just wanted to let the "off brand" guys have a measuring stick for EFI vs. carb price.

On the flip side, I'm putting a 390HP Hemi drivetrain in my '37 truck (avatar pic). Your LS stuff is once again half as much, but I bought the entire truck (wrecked 2011) for considerably less than I'm paying for the Holley stuff.

[DarkoNova]

Ah, I didn't know you had a Mopar either.

My bad.

[thedodgeboys]

Yep us MOPAR guys gotta pay twice what everyone else has to...

Mice build BTW

I did the same. Holley HP. Build thread HERE (http://grassrootsmotorsports.com/project-cars/1968-chevrolet-camaro/) Had a really nice working, custom-built carburetor. But after moving from NY to FL, I learned that engines don't like to run on water. So I'm blaming the weather.:dunno:

[Steve Chryssos]

Oh yeah! Biggest decision was sorting out the fuel tank for my custom application. Instead of simply turning on my brain, I tapped II Much Fabrication and VaporWorx.

Got a gut in out area that has a 440 that has a procharger on it and megasquirt efi that he did for under $1000 just for the efi setup and he really likes it and it's easy ability to tune. Don't know what he is making for power but it sounds real healthy.

I am in the process of making a switch to Holley HP from a blow through carb. Money aside tuning the blow through was amjor headache and was never 100% correct for driving. I sold all of my stuff and made half my money back. Even though my is a Chevy, I looked at going with a 6.0 but buy the time I changed headers, charge piping, not considering all my pulleys and everything I have invested in the sbc, it was mucheasier and cheaper to go with the holley hp setup. I chose to to go with a victor intake. By the way I have a new set of injector bungs and universal rails that came with my Holey HP setup that i will sell cheap. They are brand new if you need them for your conversion.

[DartorDemon]

IMO you don't need too many reasons to go carb'd. I'm hopefully gonna do it sometime this year. Carbs suck.

[funcars]

We do all of this stuff for fun anyway, but EFI gives so much more control than a carb and distributor.

[Tony_SS]

I'm sort at a crossroads... carb'd SBC.. and have been looking at the holley EFI or going carb'd LSx... I'm leaning toward the the carb'd LSx. I hear even those knock down 20mpg hwy.

[DButler]

If I was going lsx, it would be a no-brainer for me to stay efi.

[old66tiger]

I have the FAST EZ Multiport for my Pontiac and it works well. Better than screwing with carbs.

[Tony_SS]

All of you carb to EFI guys, what did you do, inline fuel pump?

[Ollie8974]

If the fuel tank is deep enough, needs to be 9 inches deep.
I am using a 4th gen fuel pump module.
