Fuel Injection Conversion, Part 1: Why? And, why FiTech?

It's time to replace my Carburetor with a Fuel Injection system, in my 1969 Pontiac GTO! Have you ever wondered how to do it? How hard is it? What's involved in the process? Me Too! I've never done it before either, let's see how it goes. In this video, "Fuel Injection Conversion, Part 1: Why? And, why FiTech?" We discuss why I'm converting to Fuel Injection, why I picked FiTech, and what comes with their Throttle Body Kit? While this is for my 69 GTO, it is applicable to almost all makes and models of carbureted cars. Subscribe to follow along with the process, and for other project ideas for your ride!

I’m doing this to my 95 mustang 302. Glad to find your channel. Crazy this is I’ve looked up FiTech builds and your channel never came up but I found you when I just now searched “FiTech 02 sensor install”. I just finished installing the new trick flow cam, Afr heads, comp cam rockers, trick flow push rods, ford racing lifters, edelbrock rpm air intake manifold, and BBK shorty headers. I drew out my fuel lines, needed connectors and ordered them. Now I’m going to watch your build videos on hooking up the FiTech throttle body.

I can say after running FiTech for over 3 years now, it has been one of the best upgrades I have made on my 462 Pontiac. I did have a few hiccups after the install, and that leads me to giving you a few tips: 1. Run a dedicated ground wire from the corner of the unit straight to the battery. 2. Make sure your alternator is up to the task. My 100 amp Alternator wouldn't cut it. I purchased a Mechman 170 amp 1 wire alternator (the big thing here is the idling amperage. It idles at 150 amps, whereas the 100 amp idled very low and couldn't keep up with all the draw from the fuel injection, fans, pump, etc.) 3. If you have a fuel pump larger than 255 lph, set your PWM to 100% and run a dedicated relay for the fuel pump. Just use the fuel pump wire supplied by FiTech to trigger the relay. You will love it! My car performs so much better after the EFI install.

[@FastMonty]

Nice, Shane! Awesome feedback... thanks for the pointers, especially for anyone about to attempt the the same conversion. Will definitely keep all those ideas in mind, as we move forward. Thanks again for watching, and thanks for leaving a great comment!

[@Danno74Z]

Hi Monty, I recently saw that Holley released their Sniper 2 EFI. I wonder when FiTech will release a new version of their EFI system. Like the original Sniper the existing FiTech needs a refresh. It's been in production for about 7 years now. Have you heard if a new unit is forthcoming? Thanks.

[@FastMonty]

I saw that too... I don't know what's new at FiTech... will definitely keep an ear out to find out more. Thanks for the comment!

[@tedgeldberg6498]

I've owned a 1972 De Tomaso Pantera for over 20 years. About 8 years ago, I simply gave up driving it because starting it was such an ordeal. And once I bought my 600hp Jaguar XKR in 2013, I just couldn't put myself through the effort it took to drive the Pantera. About 7 years ago, I decided to make it a more driveable car, otherwise I was going to sell it. Originally, I took it in to my mechanic to just convert to fuel injection but that turned into a full blown restoration/modification. We put in a new built and stroked 351 Cleveland with north of 500hp, new exhaust, new interior, new paint, the whole 9 yards. My joy was nearly unimaginable when the first time I turned the key, the engine roared to life without me having to remove the air cleaner, dump gas into the carb, start the car and then do the reverse order, sometimes 4 or 5 times. It was great until the engine warmed up to about 180*F (certainly cool for a Pantera) where the fuel injection would first sputter for a minute and then shut down completely leaving me stranded in some very dangerous situations. Back to the mechanic it went with each attempt at correcting it failing to do so. It still kept happening so I took it to my regular mechanic for my fleet of cars for many years. And after nearly 3 months of being unable to diagnose the issue and no amount of attempts to reach Holley technical support, he suggested we yank the fuel injection and replace with an Edelbrock carburetor. It has been a month, and I've driven the car a lot during that time, and it has run flawlessly for the first time in 20 years of ownership. Sure, I have to go through the sequence of priming the fuel system, activating the fuel pump, depressing the gas pedal to the floor 4 times before starting, etc., but it works. My words of advice for fitting to an older car that didn't come with an ecu made to handle fuel injection, is to make sure that you purchase the system from a company where the customer/technical support actually exists and where they can help you work out the kinks. I suffered for 2.5 years after a ground up restoration wondering everytime I drove the car where I was going to get stuck on the way home. I hope you don't have any of those issues.

[@FastMonty]

Noooo ! That's a hard pill to swallow. Thanks for sharing that story, Ted. Obviously no one wants to go through that kind of pain, and I totally understand the decision to back to the "way it used to be". I'm dying to know why that would happen... I'm not an expert, yet. :) Thanks for tuning in, and leaving a comment!

My 70 Z28 4 speed is numbers matching Z with the orig List 4555 780 Holley so I can’t go FI. I like watching others wrench on their cars cause in the winter, we have snow here in Ontario outside of Toronto. Looking forward to the coming videos. P.S. it doesn’t take me long to tune my Holley or swap jets. I could rebuild this carb blind folded since I’ve owned the car since 1981.

[@FastMonty]

Excuses, excuses... ha, ha! Nothing wrong with keeping things original. And, you are a rare breed when it comes to Carb knowledge, not many of us know how to properly Jet a carb. Hence my point about having a properly tuned carb, not many of us have one. :) Stay warm, and thanks for watching!

Hi Mike, I have a 1964 Chevelle Malibu SS with a custom built 327 and a Tremec 6spd. This was a frame off restoration and looks very nice but still needs improvements and upgrades.

I chose the sniper EFI system from holly because they also had the full ignition system with distributor. I purchased those with a full rewirring kit (to modernize the electrical system) All before I found out I had to rebuild the motor. I think I may also get the Sniper digital gauges as well.

Since that video, I rebuilt the engine, replaced the RPM Performer intake with a Torker II, painted the intake Pontiac Blue, Installed a Tremec TKX, RAM Dual Disc Clutch, FiTech fuel injection, Gen 3 camaro in tank pump, with a Custom Ricks Tank, and an Adjustable PCV valve from M/E Wagner. Filmed all of that too... and, yes, I still have the FITech system installed, and love it!

[@ronpeltz8386]

Mike, Make sure you get a new coolant temp sensor. The one that comes with the kit does not read properly (approx. 20-30 degrees cooler). Much talk about it on different forums. I had to buy a new one also for that same reason. Enjoy. Your gonna love all you can do with it, including having it control timing!! I love mine.

That fi-tech you bought is that the one you can control ignition timing on and if so can you still run a normal HEI distributor and not control ignition timing?

Hey Brother, good question. I currently have HEI, which means you can NOT control timing via EFI. Hope that makes sense... in a future video, I'll be converting to timing control, which can not use HEI.

[@omgbbqcia911]

yeah sorry the whole "easier cold starts" will never sell me on any fuel injection. hmm.. let me see. spend thousands of dollars on the conversion kit, supporting fuel system mods. possibly redo all my fuel lines and a new fuel tank, modify my exhaust for 02 sensors and spend countless hours wiring........OR take a flat head screwdriver and 15 minutes to properly adjust my carburetor. also no carburetor is "tuned for wide open throttle" no clue where you pulled that from. my edelbrock AVS2 carburetor is properly tuned and in my Pontiac with a 400 V8 starts right up first 2 revolutions in any weather and you can stand right next to the tail pipe with no raw fuel smell. bottom line is these fuel injection kits are big money...ONLY result in better start ups for people with no clue how to properly adjust a carb (which isnt that hard to begin with) and in the end you spend thousands of dollars to get a 90's TBI setup on your muscle car.

[@FastMonty]

As I said, nothing wrong with loving your carburetor. Yeah, a properly tuned carb needs to be jetted, while taking the data from a dyno, at wide open throttle. Glad to hear you got that handled, cuz not many people take the time to do that. (I did, and it still wasn't quite 100% optimized) Ohhh, and when you put it on the dyno, what do they stick in your exhaust pipe? Yup, an O2 sensor. Thanks for the comment!

I have been working on, rebuilding, and remanufacturing Q-Jet carbs since high school in the mid-80s. If you can only set up your carb for WOT then you need to pay someone that knows what they are doing. Your opening statement is ridiculous.

[@FastMonty]

Thanks for the comment... I'm glad we have a carb expert on hand. Would you mind elaborating on exactly how to tune a carburetor, for a modified engine? Thanks!

[@HastyRhombus760]

@@FastMonty I have a factory Q-Jet from my OEM 400 out of a 1975 TA on my current 647hp/627 torque stroked 400. To set the carb up right you have to know the different circuits of the carb and how they interact with each other. Then you have to be willing to completely tear down and remanufacture/modify the casting and most of the brass parts. About 15 years ago I came across Cliff Ruggles and his book which taught me some new things and some different ways of looking at the Q-Jet. I strongly suggest buying his book to anyone who wants to get the most out of their carb. He is also the best supplier of replacement parts and rebuild/reman kits.

[@firebird70]

Hi Mike, just wanted to add that i have been following along with your project, watched all your vids, great work, keep it up ! Also need to add that both Edlebrocks and Quadrajets carbs offer the ability to tune all regimes below WOT, period (not just wot or based around wot). Learning how to read plugs correctly and use an o2 sensor helps and guides along. I realise easier said than done, but very much do-able. Bypass the road tests and use a local hub dyno and ya done. Repeat once a year to check and adjust if you're keen. Nevertheless, i appreciate you're going down the path of trying FI. Check out the channel called "Nashville Early Bronco", he's done dozens & dozens of videos on his fitechs, all containing good feedback. I've also been following others etc, it seems to be a very controversial topic. From my experience in following others with it, i'm not sure it is really worse the hassles over a carb, more goes wrong with it than with a well built and tuned carb, But i will follow along and hope to be proven wrong lol. Cheers, JB in Australia.

[@FastMonty]

Great comment! Like I said, properly tuning a carb is not that easy. :) You have the skill set of about 1% of the carb owning population. Which is awesome. Totally agree this is a controversial subject, as I've seen from all these comments. We shall see how it goes...

But, I was originally taught carbs in auto shop when I was 14, and that was 47 years ago, I still have couple of classics with them and they run well. With custom builds, It's all in the setup and adjustment and they can run as well as fuel injection in most situations.
