At what cost would you convert to EFI?

Theoretical Question - What is the price point that it would take for you convert your car over to EFI? Talking about street, mild street/strip type cars. Talking about a bolt on fuel injection like FAST EZ EFI, MSD Atomic, Holley Avenger, etc. Just talking about total cost of the system.

You could not pay me to ever run a carb again.

Re: At what cost would you convert to EFI?

i suppose that i might on a mild street/strip (driver car).
i would think that my fuel system costs are pushing $2000 for my blow-thru application, so

My issue with current batch of EFI plug and play is most do 450-550 HP then the price doubles for up to 1000hp so guys pushing mild large displacement BBCs with 650-700hp gave to pay double, happy to pay more but not double. $2500 would be my limit for a 1000hp set up. For mild street I think 900-1200 is fair in comparison with a carb that suits

Re: At what cost would you convert to EFI?

Like my carbs but if I had to..say $1000 ish. Proably not realistic though.
Agree with the $/hp statement

Re: At what cost would you convert to EFI?

I have the complete Edelbrock Pro Flow 2 EFI system on my BBC 555.

Cost substantially more than your upper threashold however, but performs great with

excellent tunabilty.Throttle response is instant and clean.600 RWHP.

Would never consider returning to carburation.

Re: At what cost would you convert to EFI?

I would say about $1,500.00 max for the conversion would convince me to change.

Re: At what cost would you convert to EFI?

I've been thinking about doing this..

My biggest issue is the price of intakes and rails.

I want an under 250$ intake, and a set of rails that are not so expensive.

I will use megasquirt for my fueling and maybe spark. It would be speed density. And only really have an iat and tps.

I could make a harness pretty cheap, or buy the $100 generic one.

For a street deal, injectors are cheap. Use a set of newer GM/ford injectors. I sold a set of brand new 39# cobras and GM 42# a few weeks ago for 100/ea.
The new GM ls3 injectors are iirc 42-48# and you have to basically give them away.

So I guess in the end.. $1000-1500 ish is the realistic price.

The factors that drive it though are cost of intake, throttle body. ECM, rails and if you buy new the injectors.

I love carbs, and actually don't care for efi. But it would be cool to have since I now have a 700r, and I'm planning on boost in the near future.

Re: At what cost would you convert to EFI?

But ultimately. The cheaper the better.

Under $1000 for everything would be killer for a MPFI set up.

Megasquirt package kit with ecu, harness, but need to assemble is $600, add 350$ intake, $250 rails, $250 injectors, $300 throttle body, $50 misc connectors from junkyard.

It all adds up for sure.

Re: At what cost would you convert to EFI?

I converted my 1965 Chevelle to the Edelbrock Pro Flow about 15 years ago and I will never go back to a carburetor. The car is so much better to drive and dependable also. No more fouling spark plugs from too much fuel. Gas mileage went up and under hard throttle the exhaust is nice and clean (No black too rich smoke). The cost of the unit is only part of the cost of the installation. If I remember correctly to total cost was around $2,500.00 15 years ago and installed it and I fabricated all of the various upgrades myself. One big item is running a secondary surge fuel tank with two fuel pumps because the 1965 gas tanks do not have a sump to prevent the fuel from staying around the fuel pickup under hard throttle. Which the fuel injection definitely helped with. Lots of low end torque. Need a return fuel line back to the tank. Now you might be able to buy a tank with a sump in it now for more money. You will need to be able to do a Lot of electrical work along with a high output alternator.

Re: At what cost would you convert to EFI?

What would be awesome would be to have a plug and play cheap kit that uses a GM PCM that's supported by hptuners. Something simple, that'll fire just fuel, or spark if you wanted.

Since I already have hptuners for my gto, it would be nice to be able to use that since I spent $650 on the software already.

Maybe I'll hobble together something using 96-00 vortec truck PCM and harness, since iirc that PCM is supported by hpt?

Re: At what cost would you convert to EFI?

Doug I'm happy you asked that quetion. I talked to about converting my set up to your system by email back in November of last year.
I had already purchesd the Holley ecu unit which I got for $1000.00.You recomeded eveything else that I was going to need to finish the conversion which would have been another $2300.00. So total I would have spent over $3000.00.
You were very help full, But I desided against it over the total cost. I sold the ecu for $800.00 and stayed with my carb.
If I could do it for $2000.00 I would be in like flynn.

67 Chevelle 509, 4L60-E, 342 rear gear. so far low 6.17 with a 1.34 sixty on motor 1/8. 150 shot of nitrous 1.21 sixty 5.63 1/8.

I haven't checked lately but the last time I made an inquiry to HP Tuners and EFI Live, they did not support any GM PCM (E38 and E67 variety) without a valid VIN. And, to use those you will need the correct 4X Cam sync signal and 58X (60 minus 2 that is) crank signal. I suppose you could use a 1X Cam/24X crank/E40 ECM which would be less $$$. ATI quoted me about $750.00 for a super-damper with an integral 58X reluctor. EFI connection has the correct 4X Cam Sync distributor "plug" but they only support the later model Gen VI EFI BBC's at this time. I really wanted to go coil-per-plug and a GM E38 ECM with a base Corvette Z06 tune for starters and use HPT or EFI Live as my tuning software.

Fuel systems are another story. I have a Rick's Tanks stainless tank set up for a 2009-2011 Cadillac CTSV Fuel pump module (capable of 1000+HP NA, 900HP boosted) and a Pulse Width Modulated feedback control module which maintains 58 PSI regardless of the engine's demands up to the limits of the pump module - no regulators or return lines, just like the late model OEM's. I'm into it for about $2000.00 including the -8 stainless hard fuel line rear to front with fittings. I wanted something different but sometimes I have to wonder at what cost!

So, at this point in time I don't believe there is a cheap way out for a late model GM ECM. Maybe FAST XFI, Megasquirt, Edelbrock, Holley, Accel etc. aren't priced too badly after all but you have to be willing to pay the price and learn to tune. Driveability and dependability are a plus, cost being the BIG negative.

My two cednts worth

Re: At what cost would you convert to EFI?

In my opinion, a complete bolt on system, intake,manifold, throttle body injectors,computer control,s sensors and fuel rails that sold for about $1500 would be priced low enough to be competitive, as theres some advantages to running EFI, but once you exceed that price level, your really well above what a good carb and intake costs, and I talk to guys constantly who would love to swap, but just can,t justify the cost, theres enough difference to make the choice to swap to EFI rather economically prohibitive.
As Im sure your aware a good running carb and intake can be had for well under $1000-$1200 for even a rather high hp engine

Exactly my view on it. EFI would be so much better for road course type driving, but so pricey to get one capable of the 750-1000 hp range. I think kjett spent a bundle on his EFI setup, so he'd likely be the guy to ask. Pay to play I guess.
