FIRST START: Carburetor to Holley Sniper EFI Conversion | '67 Pontiac GTO [EP17]

Hello, rich, can we

start

? No, they gave it to you four years earlier in the GTO bill. Prime it and paint it inside this shot and then we'll take it to the paint booth and spray the putty on the outside. Okay, we're at Joe's. transmission drop since he was about 16 years old. Good hockey tape looks a little older. The extra steps to make sure this car is perfect and you buy your engine. The 650 car with Electronic Show told me it's really rare, really valuable, oh, I'm bringing it to you, the car expert, how much do you think it's worth?

Online research shows it costs between three and four hundred dollars, that's what I expected. getting these things are worthless oh ok so I had a friend who had a numbers matching 71 GTO judge and he hated the car because it wouldn't stop, wouldn't hook up, he was picky on the

carburetor

but couldn't change anything. because it was known to match so he sold it, we have the 67 GTO here and basically everything from the top of the pillars down is new. None of their numbers that matched how we had the block were a 69 even though they told us it was original.

Not so, that gives us the freedom to make some updates to it. One of the easiest upgrades, honestly, is the Sniper EFI. I came into the world after

carburetor

s and people swear they can adjust their carburetor and less than here. but it's impossible to do what this little guy does here so this is a complete kit and basically for just over a thousand dollars we have the

sniper

system that looks like a carburetor so it still gives you that factory look but the EFI that comes with it, your kickdown cables for your transmission mounts are on the side, all the wiring you need comes with it, along with the touch screen and an O2 sensor for the exhaust, if you're going from a carburetor to an EFI system, you're going to We have to put a CO2 sensor on it and it comes with a solderless system.

If you have a really nice exhaust, basically drill a hole, put a cover on it and clamp it shut, but our exhaust already has an O2 sensor so we don't need this part, we opted for the full kit which gives you a fuel pump, the pre-filter and the Astra filter and then also gives you the necessary hardware to put the return back into your tank and enough fuel line to do it all. the hose clamps, everything you need comes with a kit which is really good, if you don't want to use an external fuel pump and filter you can use an internal one.

There are many fuel tanks available for most popular cars. We have the fuel pump in the tank, we already had our tank, so we went with this. This setup also has a temperature sensor that won't put the engine into closed loop until it reaches a certain temperature, so we'll incorporate all the wiring for the

sniper

into the factory harness and then tape it up with hockey tape so it looks like the original 67 but it still has the upgrade we want as a driver we will have some fun with it we would love to do a power tour with Once we get this back up and running I would like to find the original owner and go visit him to see if maybe you have the original block lying in a corner somewhere, that's fine, so all the improvements we've made to this car. if you really don't know they are there, unless you look very carefully and they can always be reversed, if some purist wants to return it to the original anyway, for now we will put the sniper on it, it will really help us with our mileage which is the most important.

I think it's a much better investment for a thousand dollars. Oh here we go, sniping involves a bit of waiting. Don't be too scared, no, it's okay, it's not a big deal, just a little. A bit of wiring, what I should be worried about is the original GTO wiring, mainly because there isn't much marking and this isn't originally the split loom, so some of it is marked like it says glove box, so I know it's on the passenger . On this side it says fantastic purple to red, but when I look at it there is one wire here and just a couple of small wires, yellow wire there, but for the most part they are pretty well put together and not cobbled together, so I'm going to read the label with what is labeled. and I'll clean it up and just inspect the wiring, take my time, I'll get it back not with electrical tape but with hockey tape because hockey tape, which is a little bit more vintage, it has that little texture and I like it better.

Instead of splitting it up, we're going to cover it up nicely on the inside, put the engine harness together. I will not cover the end and the harness with the loom. I'm going to bring in the sniper wiring at the same time, here we go, just like that. Although we are redoing our entire engine harness and it seems a little daunting, a sniper wiring is actually very easy, we just think we're building a complete car, we're going to put our harnesses together and one harness led to the other and we're just going to put that in. this video, so here we go, if you are doing a retrofit, you will have to remove the carburetor.

Be smart, let's connect the battery because you're going to have to disconnect the fuel lines, you might spill a little bit, make sure you catch it, catch it with a can or a rag, whatever you have to do, disconnect the vacuum lines. I have a vacuum advance that goes to the distributor and anything else, mark them because they may not go to the exact same place so you know. where did they go and if you're like me you can take off this steel crouch and go, focus more on installation than disassembly, got the sniper to screw it in, it's not rocket science, I have a few plugs on the side, we have our main harness that's coming and it's going to have some wires running into the cabin, they're all labeled positive ignition power and whatever else, we've got a relay and our fuse to turn the thing on on our blue wire, we'll also go into the cabin and then we'll come back.

This is for the fuel pump we're going to add a negative cable to it at the same time just because and then we have black and red that's going to go to the batteries we're going to put a dual position battery on it and then we're going to run our efi on its own so we're going to do that on the side post and then we will do the

start

er and everything on the top post. What you do is you remove the computer that's in this thing away from everything else, keeping in mind that the bases can't have too many bases, especially with an old car like this, we're going to ground the hood and we're going to connect to Earth. the engine all extra, just so there is no interference with anything going on here, this will not make up for a bad mechanical engine and one of those things is interference, the other plug on this side is for the O2 sensors that we Lo we'll take it back, we'll have the plug ready to put in the exhaust, which will appear very soon, we'll take it out and put in the temperature sensor plug, which is this little one here, and we'll put in our touch screen. into that and run it into the cabin through an eyelet and here we go, the engine wiring harness.

I broke it a little. I don't think it's a good idea. It was under a tape. There is a tape. I don't know. a lot, so I know this starts at the firewall and this isn't really what any of you are worried about, but I'm going to get it on track. I think this is the alternator regulator. Let's put all this so that no one sees it. then tie up holly's wiring so if you open the hood it will just be an engine let's clean up the valve covers a little bit hopefully yours won't look like that okay so the removal process we have a wire here with a single spade connector that is not long enough to reach the oil pressure sensor so this is the coolant, this longer one with a single spade connector is my oil pressure sensor that is in the back somewhere place, let's throw what we have there. these two that connect to the alternator regulator plug, so these are my field and armature windings.

We have a big purple one here that goes to the power switch. Imagine this would go to my dealer. These two black and red wires were positive, so they would go to the starting brake inverter. Pig, we have this covered wire here that I don't know where it went, it just went positive so I'm not sure where it goes. I'm going to put some new wires in, if the wires look good I'll probably put all new ends in and trace the wires back and then we'll put them in with the poly material, it's easy, we'll fix it, no, I won.

Don't film that and then we'll go back to the Holley, here we go and this is how you hook up a motor. I haven't fully turned on the loom yet just because you never know, but essentially I need an adapter for my pressure sensor. or my temperature sensor and everything connected well there, the air filter will cover a lot of it. We have our two wires run here that will go to our battery and I'll probably connect it to the headlight lomé fuse on the relay. for the fuel pumps in the fender in the back here the alternator relay will go right here and then in the back there cover it with a loom just those random current lighters I need a plug for the back of this we have the wires working in the cabin there's no grommet right there and we'll probably make a grommet on this side by passing our canvas for our digital board and I think it'll go in the glove box oh, you won't be able to see anything other than when you flip the glove box down, it'll sit just fine there.

I was looking at new valve covers. I don't know what to do with them and I think you already realized that. I think I'm going to sand them, paint them matte black, and then just shave the top so they're shiny. I'm going to leave these nice, elegant black letters here and here and then the chrome will stand out really well. Then maybe we need a brushed aluminum entrance. I don't know anyway, let's stop. There and the night ends, here we go, okay, then the magic happens in the exhaust, something huge, in this little sensor, the O2 sensor.

Now what this does unlike a carburetor is instead of just guessing how much fuel to throw into the engine. The O2 sensor determines how much oxygen is left and the computer can compensate for how much fuel enters the sensor. It's pretty critical where it goes, it has to be at least an inch, preferably one to 10 inches, behind the manifold where the four exhaust manifolds meet, so we have enough room, it's in a nice deep area, and the collectors stop right here so we can get pretty close to the flange without having to put a plug in our nice stainless steel if not.

I don't want to do the stainless steel and the kit comes unwelded with the clamps, we are still going to solder a plug on our header so I dropped it. You also need to have your O2 sensor as vertical as possible and what this means is that moisture comes out of your engine and if you have it at the bottom where it is easy to reach, the moisture settles on the sensor and your sensors will not last long, so let's drill the hole. Here we're going to weld on our bung to make sure we don't hit the floor, but we can make a little angle here, we've got enough to screw back into our exhaust, so here we go.

I mounted our fuel tank got some new belts and a new tank and we need to mount our pump now our pump needs to be below the surface of the fuel and as close to the truck as possible so I'm going to make this bracket here. that's going to be like this, I just give it a couple of bends, put it like this so it's at an angle here and then we'll attach some pieces here so we can take it off, it's necessary if we need to take the straps. off and then we'll mount our filters and our pump directly to this thing, so with the EFI there are a few things that you need, you need a higher pressure, so you need a fuel pump, it also needs to come back in our kit that we have. our fuel pump and our pre and post filter for nice clean fuel.

I opted to put a line on my sending unit for the return, but that gets really complicated if you're good with brazing and all that, you can try it. the problem is you have to run it through the hole and you also need the downpipe so the return goes to the bottom of the tank pointing down, you can't just empty it, you can't just drill a fitting in your tank and throw it away because it will aerate the fuel and you will have some problems that way. I also need to have the down tube at the bottom of the fuel to put the fuel back in.

You can't have it at an angle like this because it will start to spin the fuel and you'll also have problems that you really don't want, so the fuel pump is the blue wire that goes to the positive and comes in the wiring harness and then you just hit it. will give a good clean ground connection. Tie that up nicely with our wiring for our sending unit, we'll run it into the cab and run it under the floor and insulation keeping it out of the elements and Holley recommends running the wiring through the car. remove the cell plates and lift up the carpet a little, put the wiring in a very simple way, okay,The tank is painted, the transmissions are painted, but I'm waiting on a torque converter which should show up today.

I received the last of the cables they passed one more cable to go and the battery cable ends, but the paint took all yesterday to dry. A little dilemma here, who are you? Because you're going on your honeymoon, yeah, and I'm going to California, but I'm close to shooting it like all the embers are out. I just have to reposition the tank and program the sniper and we are ready to fight. The problem is there's also a snow storm outside, whether you've done this drone probably in the next hour you should be able to just lean here, give me your Timmy, yeah, he's happy, I'm happy, it's like a big presentation for me and about two or three weeks when I come back and it will be running and painted and I will be the happiest man in the world.

I think he'll be disappointed because I was gone all week, so it'll be okay. Well, the tank is all well painted and so are the straps to protect it. I just received this locked cell. insulating foam that's sticky on one side, you get it at the hardware store, they use the skin under truck hoods and stuff like that, so I just put a strip where it hits the bottom of the trunk like that for the back of the strap and then we get We don't have steel on steel, we don't have squeaks and we don't rest, so here we go, okay, we've got things under control a little better under the hood, here we have our coolant temperature sensor, there's just a couple of wires you need to connect, the pink one needs to go to an ignition source, but you need to be careful that the ignition source also has power while you start, there are many circuits that will lose power as you start and that As a result, we don't start, we have the coil on the lid here, it says right there.

The yellow TAC wires for the tachometer touch screen simply plug into the unit. I put it through this port right on this side here, but I'll probably go out to a port somewhere here and put it in the glove box for now we're just checking it from there, we're going to turn the key a couple of times to make sure that Our fuel pump is working, but we are going to transfer that fuel to a can. New tank New lines, but those lines were bought and paid for I think five years ago, so there's probably dust inside.

We want to get all that junk out before it hits the sniper. There are three ports that you can connect to later to feed it with fuel. go back here to the front for the three ends but the return has to come out of this regulator and that's your fuel pressure regulator definitely check these fittings and make sure they're tight don't take anything for granted. I'll show you guys. fuel pump setup, fuel supply has to be 3/8, that's a brake line on top. I have the return going down the other side now, that only has to be 5/16, but anyway I ran 3/8 all the fittings were 3/8, you have our fuel pump in the back, here the prefilter and the rear filter, all the wiring is well inserted, it follows a long route upwards and then enters the cabin right there, which will go under the carpet that we have. our return goes back to our sending unit, the ground for the tank can go to the ground from the pump and because they just share that ground anyway, the exhaust looks good, you're missing transmission, but that's on the way, so let's bleed that fuel tank. and see if it triggers at like 1:00 in the morning, nothing good happens after 7:00 p.m.

Italy okay, once we have our pink wire connected to a good ignition source that has power while you are booting up, you will enter the

first

screen that you will see, it is your main settings, we want to go to the assistants and we want to leave it. we know what type of unit we're using so that's the one we have that's the one we have the next cylinders um that's just sad that's for Commons that's for the muscle car engine displacement it's going to go with 1400 and now it better be let's let him know it's a 400, fortunately they give you this pen because it was a big toe syndrome, which is what I have, it becomes very difficult.

The auto target speed will work at 750, that's a good place to start. You can write, we have Street Strip, we will do it. There are no power add-ons, but you can add nitrous and this will also control things like electric fans. There is another plug that comes with the kit. We're not using it and we have a negative coil if you're using like the Holley Dual. sink, you can control the time on that, which is even more fun, we're not there yet, maybe in a short start it loads what it needs to do and we just need to cycle the key and we'll be done, okay?

You should hear the fuel pump turn on ah ah we have the fuel pump and fuel comes out we'll do this three times and then we'll connect the fuel line and then we'll cross our fingers to check our fluids one more time. Okay, nothing left to do but turn the key, hey, hooey, high five Kenny Kenny Kenny wake up Kenny Kenny, the GTO run, buddy, high five, high five, kitty, hey, I got your call and let him hear that. Oh, anyway, many. There are good things coming with this car, but major progress, here we go, so a little behind schedule, you know, hope this gets done before California, but who are you, yeah, yeah, back for the moon honey, gaining a couple of quid, yeah right.

What happens when you go to a resort? Anyway,

first

you turn on the key and a screen lights up. I get it so fancy that it has gauges and everything and then it's huge, yeah. Holly doesn't do cool things, turn it on, yeah, like that. I don't even like turning twice, it's working, yeah, a very good water pump, so I'm glad you were here to enjoy that because now I'm going to destroy it all again. Next up are the brakes before with this brake installation and then we get an interior. We've got a couple of finishing touches on our engine and we bumped it up a little bit, we've got the RAM here so let's go, but we'll include it in the final order with a couple of trim pieces that we're missing, we'll get the The dash should be on the order list and then this time we will build the... completely, so we have all new wood grain for the interior because that's not cool.

Put the lenses on. Put all that. There are a couple of light bulbs that are off. I have to check them out, we'll finish the wiring that's done right here, that's all done by the engine, make it nice, make it nice, but that's all we can do while it's in the paint shop, it's just arriving. together so fast now it's because you've been gone for two weeks oh like Von's been gone for two weeks here I'm working all these little things take so long oh it's coming together so fast and it's on the way yeah hey guys um just one quick note.

I just want to let you know that we have moved our merch to teespring. Their integrations with YouTube are a much better setup. We redid a lot of t-shirts. Now we have stickers because everyone. I've been asking for stickers. I'm not really a sticker guy, but they're actually our number one seller now, so we'll be creating some new designs, so check back often. Aaron handles most of this stuff, but I hid a few fancy ones. The shirts are out of the deal, so they're still somewhat clean. I think this is theirs and they wanted it back, but it's already dirty.

Thank you guys for your support, thank you for taking care of Kitty.
