- In this video I take you on a tour of how I turbocharged my buddies 2.2L S10 using the factory computer. The information given is for entertainment purposes, viewers assume all risk if they choose to try this.
You guys did a great job.
Thank you, and thanks for watching.
Very cool! Similar to how we do NA-T Subaru builds or how I did my $500 turbo car. All the same principles, of course. I'm good friends with Oliver and I actually helped him figure out a lot of the same stuff you did. I think we gave him a lot of the same tips and then he would come to me with ideas you used for clarification too, hahaha. The "Active Fuel Management" sticker absolutely slays me. The cavalier manifold was clever. Was trying to find an injector solution for Oliver and the only thing I could come up with was Kodiak injectors which should be a bit larger to make it easier to handle boost. Rather than go with a small block you could probably go Speeduino or similar and get a lot more control too. Good stuff!
Thank you, I'm glad you like it. The truck has been in this configuration for a few years now, and my buddy is getting ready for a change. The plan from the start was to put a V8 in it, turbocharging this engine was just for fun. I really enjoyed figuring it out and working through all the bugs and quirks. After injector problem after injector problem, I had had enough of those things, and I had all the other parts I used laying around. In the end it worked out pretty well. Yes for sure a standalone controller would make a big difference, its just not my call. Whos to say the small won't end up turbocharged in a similar setup. Once your addicted to boost its hard to go back.
I ran into the same wastegate problem with my Maxpeeding rods t3/t4 on my 3100v6 c1500. had to do some porting too! Check out sleeper sunfire, he has a built 2.2L making around 440whp!
Wow that's impressive. I believe with this setup at 10 psi, all stock internals, probably added somewhere in the 60-80 Hp range. I'll check it out. People like to hate on the 2.8, 3.1, 3.4 engine family. I'm a fan, great little engines. I've had a few 2.8s over the years and beat on them pretty good, and they just took it. Plus I love the firing order, 1 2 3 4 5 6.
@TheBackyardTech yes they have a lot of potential, but they don't have enough aftermarket support for people without welders lol
A friend of mine has a stick s10 like this one that had a budget 34/3500 setup in it with a cam and two China t3/t4s and put down 352whp/349wtq on 10psi. Truck now has a LZ4 SBE 3500 in it with a cam and upgraded turbos and put down 450whp/386wtq!
@@TheBackyardTech im in tx and the the dirt tracker around here run a class called mimi mod 4 banger cars the good cars are the fords and the chevy run a iron duke 4 and they give them ford a good race im not a ford guy but u need to learn about all u can and this is a cool setup
Thanks for giving the negatives on turboing a 2.2L. I have a 98' with the OBD11, so will not attempt turbo charging it, which is disappointing. I have had nearly every GM turbo vehicle from the first Gen Corvair to the Buicks and a couple of Mustangs including the game changing SVO. So instead of a turbo for my much loved S-10 I will acquire a new Colorado with the 2.7-T
You can turbo the OBD2 S10, it's been done. It just can't be done in the manner I did. With a unlocked Ecm or stand alone ECU and a proper Tune it will work. It's just down to how much you want to spend. The 2.7 Colorados are a nice truck, I wouldn't mind having one myself.
Thank you for the post. Im looking to turbo my 2.2 and there isnt really much help
I'm glad you enjoyed it. Hopefully it gave you some of the information you were looking for.
Picked up a 94 s10 with a 2.2 and 5 speed out of the local junkyard. Paid scrap price for it. Never even tried to start the 2.2. I tore the whole drivetrain out. Replaced it with a 5.3, 4l60e and a 8.5 posi rear end. Not going to be a racer just a fun driver. Swapped in some Cavalier bucket seats and a floor shift center console from a Jimmy.
Awesome. I'm doing a budget LS swap on a 95. 4.8 4L60 and a mini spool. Trying to see how cheap I can build it, within reason. Not just hack it together.
@TheBackyardTech had a 4.8 in my Silverado and it was a great motor. Will scoot a s10 along just fine. I've been running a mini spool in my 02 2.2 daily driver s10 for a couple years now. Makes getting around in the winter much better.
I'm doing it simply for the fact that it was the cheapest option to get both tires locked. They have there down sides, with low speed cornering chatter and tire wear. I've also seen them chip the corners on the spool, just from stress. But I'm not too concerned, if it all goes bad, I have a few ford 8.8s kicking around that I could swap in.
@TheBackyardTech it's just my beater with a heater. 2.2 doesn't have enough power to get out of its own way let alone break stuff. I did put a Yukon posi in the 8.5 rear in my 5.3 project though.
And a cost break down on it to please sir would b cool to ive know a guy that got a B2200 MAZDA TRUCK WITH A 4 CYC BUT IT CARB
This was a few years back so I'm not 100% on it. I can give you a general idea. 200 turbo, 200 intercooler, 500 afr guage, 100 fuel pressure regulator, 150 fuel pump, 60 potentiometer. 250 universal piping kit, 400 exhaust and mufflers, 100 in guages. 60 blow off valve. A few head gasket kits, head bolts and oil, filters and coolant. And bunch of stuff I had laying around, and I'm sure there is a bit I'm not thinking of. Keep in mind this is Canadian money, so our prices are usually higher than US prices. Hope this helps.
I never understood why GM didn't put the Quad four or the ECOTEC in their S trucks.
That's a good question. My best guesses would be, the quad 4 probably didn't make the low end torque that they wanted for a "truck". And, the ECOTEC came out in 2003, the S10/Blazers were discontinued in 2005, the Colorado was produced along side, coming out in 2004. Knowing that they already had the s10s replacement, probably wasn't cost effective to use the ECOTEC for a 2 year run. The Colorado released with the atlas platform of engine which GM had experience with from the Envoy and Trailblazers. So I guess that was the engine that ticked all their boxes.
Hey i know its a long shot but could you ell me how to wire ip the potentiometer and stuff like that and even make a sorta parts list im getting a 95 and wanna do this to it seems cools. The s10 im looking at has a rebuilt engine woth about 15k miles on it
The wiring diagram for the potentiometer is in the video. But the idea is that you put it in the place of the engine coolant sensor. As for a parts list, I put this truck together like 3 years ago, so I dont remember everything little thing. If you go back through the video I mention most of what I used.
Brooo , where’s your backyard exactly ? I’d love so have this set up on my s10
Canada lol. It's very fun. But unfortunately we haven't been very lucky with engines. Bad injector ruined the first, then got one that had no oil pressure and the oil was full of bearing material. The one that's in it now has started to burn oil in the #4 cylinder. So the truck is going to get a v8. But if there is enough interest, I might consider doing a build series in a similar fashion.
@@TheBackyardTech Yeeeeah I had an injector stick open and flood the cylinder. Luckily it happened when I keyed on and the starter didnt have enough oomph to bend a rod. Replaced it with some BWD injectors I had found that had like 4 more lb/hr or something like that - never could find them again years later after I joined forums for s10 builds. Not surprising being side feed injectors - upgrading to the 98+ intake with top feed is a pretty good move from what I hear.
I would say so. Just from the experience working with these injectors, I'm not really a fan. That's why I modified the intake to accept a standard style injector. Never had an issue since.
Does this work for better gas mileage. I know when a map kinda goes out it could take fuel or add
This will absolutely not help with fuel mileage. Its makes it substantially worse, and you have to run high octane fuel with the turbo. By adding more air with a turbo you have to add more fuel, essentially its acting as a larger engine. I guess in theory you could put the potentiometer in on a stock truck to try to lean out the mixture to save fuel, but I dont think it's worth the risk of cooking the engine.
just put a pair of additional fuel injector, control them with two voltage comparator trigger by MAP sensor voltage (two stages)
That would probably work. The thing with that is when the map sensor hits the the target voltages, secondary injectors turn on. You would just get "x" amount of fuel from the injectors, at those specific points. And from what I've read, voltage comparator only outputs a constant voltage, meaning injector would be full open and not pulsed. The way I did it, I just turn a knob and can adjust the amount of fuel on the fly, and the ecm still pulses the injector. I've seen a Similar setups using hobbs switches/pressure switches. It works and I've tried it, you just dont have the adjustability. And when the second injector kicks in you can feel it, and sometimes makes a drivability stumbles. I'm sure if someone wanted to spend the time to dial it in, it would probably get the job done. I found it simpler to use the stock computer and just trick it into doing what I want.
@@TheBackyardTech the ground of the additional injectors were connected in parallel with the stock injector (with a pair of resistor), so it will drive by the ECU pulse, I did it on my C22NE engine, it smooth transition and pull pretty hard when the 2nd injector turn on, 8 psi stock engine, remote mount HE221w. My next plan is install speeduino and use 2 bar map sensor to get more proper tuning.
@@TheBackyardTech I doubt changing ECT with potentiometer will give you enough fuel require for the boost.
Nice. That's awesome man. This was just a mess around project where we were try to do it on the cheap. It works great, ended up running 10 psi, and had more than enough fuel to go further. But I'll keep that in mind if I ever do another. Thank you. Unfortunately the 2.2 engines are not the most robust and we killed a few, so we didn't want to push past the 10psi mark. The truck will be getting a V8 in the spring.
It does, and there was even more room to go. The 10k potentiometer would only bring the ECT down to about -5°C, if I were to do it again I would use a 20K potentiometer, or a different potentiometer, that would allow me to reach the bottom limit of -40°C that ECM allows. At 10 psi wide open in a hard pull, we were able to hold under 11 AFR. But I did have to run a better injector than the factory ones. Your idea would probably allow the factory injectors to survive, while the secondary ones took care of the boost.
I wanted to mount an AMR500 supercharger in place of my AC compressor on my 97 2.2l build, but traded it in before I got that far. Was nothing wrong with it; just ready for the first new truck I had ever bought, and already had a 2004 Colorado too. Traded the s10 in being worth less on resale. Would have been fun to keep but it was just time to move on. Had all of the basic bolt ons, a tune and a custom fabbed ram air. She ran pretty quick for being N/A and how slow it was to start out. czcams.com/video/tG4EaOHgB38/video.html
Cool man. Sometimes you have to let them go. I have a couple superchargers kicking around. At some point I'd like to mess around with them.
so dose the 2.2 deserve the amount of hate it gets ? should i avoid buying one ?
My honest opinion, is it's a ok engine in its stock form. If you are just gonna drive it, it's fairly reliable. They do have there known issues, like head gaskets and timing chain/tensioner failure, but both are quite easy to repair. For modifications there are much better options. Plus there is pretty much no aftermarket support for this engine.
Hey what brand/ model is the potentiometer
I'm not actually sure. My buddy bought it, I installed it. And it was like 2 years ago. He did some research and bought it from some website for audio equipment I believe. And I think he paid $65ish Canadian dollars for it. We tried the $20 Amazon ones and they were junk. That's about as much information I have about it.
@@TheBackyardTech well thanks 😊
How much did this cosf total
I'm not 100% on the cost exactly. My buddies truck so he paid for it. Its probably in the 1500 range, but we also had some bad luck with engines, so we had to buy a few head gasket kits and do a bunch of changes along the way. I think I remember him saying that all said and done it was under 3 grand. But if you built it the way it finished I would say 1500.
You say the steam pipe has a thick wall that keeps the heat inside. Doesn't cold air produce more HP ... Thurs the reason for a intercooler.🤷♂️.
You are correct that cold air is more dense, and will produce better HP. I used the steam pipe on the turbo hot side. The exhaust pressure and heat both help in driving the turbo. If you were to use regular exhaust pipe it would glow red from the heat, dumping heat into the engine bay and losing energy. The steam pipe being thick also supports the turbos weight.
Bro, you addressed this guy allllll wrong. This fella is one of the sharpest engineers I have seen on “you tube” so far.
IMO The “backyard” thing is for some giggles. Gm would gladly pay this guy well into 6 figures ALL DAY! For this level of aptitude, I’m dam impressed w this build .
You pretty much accused this dude of doing something fundamentally stupid………..not trying to diss on ya, just don’t wanna see a fellow s10 turbo enthusiast put anymore egg on their face 😉
@@indoorsolutions7154 Its all good, he had a question I was happy to answer it. But I appreciate your enthusiasm lol. I am actually a GM technician. I just like messing around in my garage in my spare time. I'm glad you liked what I came up with.
Would you be interested in building another intake manifold I'd gladly buy one I'm collecting all the parts as we speak
@@anthonygolembreski5566I'm going to have to decline, I think building one was enough for me. Ive got another project on the go, and I work full time. But, I found that the stock injectors work "Ok" at up to about 6 psi. Problem is boost is addictive and more is always better. We were greedy and leaned on them a bit too hard. If I were to do it again, I'd skip the FMU and just use a rising rate regulator. I think the FMU was putting too much stress on those little injectors. Some boost is always better than no boost.
