Turbo Inline Six Chevy Nova Walk-around and Drive
Vložit

- Startup, walk-around, and pulls in my 1965 Chevy ii. Over the course of 3 weekends I built a turbo kit and converted the car to Holley sniper EFI.
Bone stock internal 194ci inline six. Offenhauser 4 barrel intake, Langdon's split race exhaust manifolds, Holley Sniper EFI, Ebay turbo, 2 speed powerglide, 3.08 rear end gear. 10 psi boost - Auta a dopravní prostředky
This is so awesome! Finally someone builds a 194. Looking forward to some 0-60 speedo vids, and maybe some fly by videos. Keep up the great work cant wait for some more videos.
Yea there arent any other well documented turbo 194 videos on CZcams as far as I know. Its a fun little motor. I will film another video here pretty soon once I clean up the wiring harness. Car still has factory 3.08 gears but leaves much harder than before the turbo. I will definitely get some fly-by / exterior shots. Lots of turbo noises. Thanks for the support! stay tuned!
Build? It's a turbo slapped on a bone stock motor with an efi kit. Put some rods and pistons in it at the very least, then call it a build.
this is an on-going project. You asked for rods and pistons, I agree to those terms.....
My 65 has a 194ci in her as well, stock engine just got rebuilt and she’s getting 4 barrel swapped. Everyone rips the inlines out for V8’s, cool to see this🤙🏻
Nice! A 4 barrel carb and split exhaust headers wakes these engines up
Sweet outside the box build. Always loved the 63-65 Nova’s.
Thanks, it’s been fun to do something different. The shoebox novas are the best
I love how different this build is. This thing is awesome.
Thank you! I think one of the coolest parts of this car is that its not another cookie cutter LS or SBC. Just wanted to push the stock configuration a little more. Heck, most of these cars still have the inliner in them. Dare to do something different every now and again
@@HunterSkiff Couldn't agree more with it not being a cookie cutter car. Its probably pretty quick with boost.
this is actually insane. it sounds soooo good!
Thank you! just an ol 6 banger
Love this car and the set-up you run!
Thank you! it's a lot of fun to drive
One of the best sounding cars. Man that's sweet
Thanks man!
Nice!!! Hugs from Brazilian friends!
Thank you!
That racing cam sound beautiful 👌
Steve, that’s the stock camshaft!!!
99/100 nova vids with a strait half dozen ".. we gonna swappit for a v8.." "or we have a replace .." and there is where they loose me. Now I need to fit my 68 with a turbo.. that sound!! Calm but still... when you call, it will haul!
This setup performs so well even on a bone stock 194 engine. with a camshaft and some cylinder head work I cant imagine how much more fun it would be. Get a turbo on your 68' PRONTO!
Gotta love the inline six cylinder engine the fun and reliable engine is still affordable from 194 through 292 cubic inches
Fun, cheap, and dead reliable. Plus a lot of cars and trucks came with them so they’re practically free at this point. I would be quick to modify one before ditching it for a V8 or some other engine
Sounds like a truck. Amazing sound. 👏👏👏👏
Hahahaha sounds like a Cummins diesel I think. Clatter and all hahahahaha. Thank you
@@HunterSkiffvery nice work man! Congratulations from Brasil.
Now that you have a little more "get up and go" time for some serious "get down and stop"
Well done... Well done.
Lmao, luckily I did a 4 wheel disc conversion long ago...before I did the turbo... which took a lot of restraint. Stops like a champ. Thank you for the kind words
@@HunterSkiff So you added the "Whoa" before the "Go"? I shoulda done that to my 68 Chevelle, but I dont want to talk about it....(quiet sobs)
*bows head*
Sounds so good
thank you!
the 194 stock is perfect for boost! i can't wait to throw some at mine too
totally changes the driving experience. Next step, built 250ci!
@@HunterSkiff once I have the money to do so I’d love to fully build a 250 for boost
@@HunterSkiff 292!
I wish. Engine too tall to fit in a Chevy II
I have a 1977 chevy nova, with a straight 6 in it. I don't want to swap the engine for speed, but if all else fails I will have to. Any advice on how to get more speed or best options?
Well done I was thinking of the Holley on my stock 250 in my 1971 Nova. What intake did you use?
Thank you! The intake manifold is an offenhauser 4BBL manifold. There are some other options out there too, Clifford and AussieSpeed to name a few. The latter being really performance orientated. Going to a 4 barrel carb/ EFI and split exhaust really woke up this 194ci. the potential on the 250 is much larger
Love this
Thank you! It's a fun little setup to drive
Was thinking of building almost the same setup for a 54 pickup. Are you running the base model Holley sniper? Does it tune itself okay as a blow through setup? Thanks
This is the base, non-super sniper model. and yes it'll self tune on the blow through. works really well too
How much boost do you have it set at? I just put a turbo on a stock 235 and I'm scared to go past 5lbs. But even at 5 it made a big difference and is more fun to drive
I’ve pushed this engine to 20psi. Keep in mind I don’t have an intercooler and compressor discharge temps were going to the moon in a hurry. I’ve dialed it back since, it seems happy at 15psi. The rods are strong enough, worst case you lift the head gasket. Keep timing reasonable and you won’t have an issue. 235 should have 6.75:1 compression, it’s super low. You definitely have room to grow. Like you said it’s crazy how much boost wakes these engines up, likely because of how poorly the cylinder head flows
I like the rumble
Thanks, it has a nice rumple at idle while it’s warming up. Still working on the tune. Stock camshaft
I'm from Brazil, here we get 1000 hp easily in this engine and the Chevy 250 s is the most modified motorbike in Brazil along with the VW with 4 cylinders
Forgive me if I missed it somewhere, what size turbo are you running on this motor? I’m looking to slap a turbo on my (somewhat) built 250. It’s got a comp cam, 30 over pistons, ported head, soon to have the lump kit done to it, hei, offenhauser 4 barrel manifold, and a Holley 390 four barrel
I don't have it written down in my notes but it's a no name GT35 clone, I want to say it was a low 50ish mm compressor, low 60ish mm turbine, with really tight exhaust A/R. It is decently sized for this 194, maybe a little snug on the exhaust side. At 3500rpm and 18psi boost, drive pressure was 28psi. Compressor outlet temps between 160-170*F. I would size up for your 250. You are already off to a great start, ported lump head with a custom cam is night and day. Heck, the offenhauser with Holley 390 is a nice upgrade as well. I've put the most miles on this car with Langdon split exhaust manifolds, offy manifold, and Holley 390. Don't be tempted to run a larger 500 or 600cfm carb, it will give up some drivability compared to the 390. Keep me in the loop as you move forward with your build! ~ Hunter
@@HunterSkiff good to know. To be totally honest, I don’t know a thing about turbos. My target horsepower goal is somewhere around 330 or so. I did the math based off of a CZcams video I saw, and apparently the one that I need is a borgwarner sx300e. Now I know that’s WAY too big of a turbo for my application, so I don’t know what I really did wrong or where to go from here. What ballpark should I shoot for in terms of size?
@@wallyworksonstuff343 S300s come in all sorts of different sizes, the S300 just denotes the frame. Even the smaller of the bunch S362sxe (62mm compressor) is way too large if you're only going to make 330ish HP. Ideally for daily driving you want a turbo thats in the meat of its efficiency during regular operation where you spend more of your time driving, and on the bleeding edge under max effort. Something like the Holset HX35 would be a better match for your setup
I got a 194 in my 1965 Acadian Canso (canadian nova) and I was thinking of doing this. If you have any more info on what you did please get back to me im super interested in the complete outcome and opinion
What kind of info are you looking for? The car is still running 18-19psi and weekly driven
I’m building the exact same car, hoping to do it the same way. Can I ask where you sourced your parts from and what turbo kit is that ? Please and thank you
That is sweet! the manifolds are from Tom Langdon and the intake is an offenhauser from summit. Holley EFI, amazon turbo, and I built the kit myself. Have fun with it!
Sweet build. Wondering on doing this to my fathers 67 c10 with the 250 3 speed manual.
Thanks, its been a fun build for sure. A turbo charged 250 with a 3 speed would be fun as heck to drive. Ive been trying to convince my buddy with a 292ci powered '70 C10 to do a setup like this, maybe one day we'll film it for the channel. As easy as it is to setup a turbo on one of these engines, I would highly recommend it
I'm definitely considering this. I've been wanting to do it because a ls swap is common but a turbo 250 with fuel injection is not. Those 292 can make some serious steam with a turbo and the holly sniper kit. Most think the kits to expensive I honestly think it pays for itself over a carburetor setup. Plus a bit better fuel economy. Yea it would be the only thing is it has a short gear in the reverend i think they are 3.07 gears toped out at 115 not sure what he was reving it to if I had to guess I'd say it made it to 9,000 a few times and one of those times it dropped a valve because it didnt upgrade springs and retainers and didnt wanna wait to spend the money on ratio roller rockers. The more and more I see videos like this gets me motivated to try and pull ole girl out and get started on it. Especially since my grandfather gave it to my dad and it was dads first truck.
Oh and your very welcome buddy I love seeing these old cars with their original engine that's been modernized and can make the same power as some of our newer engines and still be reliable and throw people off except the old school guys!
I also ment to ask what manifold you are running for the sniper kit and witch kit is it I'm still trying to debate what kit to go with later down the road. Gonna start on getting her going and pulled out the hole in the ground shes sunk into. Hope to have it at least driving by the end of December for the birthday since it's the 31 of December 🤣 probably wont happen but who knows haha
The intake manifold is an Offenhauser 4BBL, the exhaust manifolds are Stovebolt Langdon's split manifolds. The Holley sniper is the basic 4 barrel kit, not the one setup for boost
I have the original Chevy 194 with a Clifford 6=8 performance kit, cam and cylinder head from 12Bolt, Holley Sniper EFI system, can you do a detailed video of what you bought for your turbo set up, I’m thinking about putting turbo on mines, thanks great video
Thanks for the support! I will make a detailed video here in the future. In the meantime, its a T04E turbo with manual external wastegate, they can be had for 100-125$ all over the internet, a 1/8 NPT oil feed line and a hodgepodge of oil drain lines and fittings, spectre intake hat. I loosely followed Turbo Camaro's build sheet here www.turbocamaro.ca/p/build-sheet.html
Thanks so much bro, I’m going to start trying to compile some of this stuff, I’ll subscribe and check back or updated videos! Thanks
Out of curiosity, how much is the change in performance from the stock head/cam to the aftermarket cam and worked head. Also what head modifications does yours have? Lumps? Port? Big valves? etc
I spoke to Tom Lowe at 12Bolt directly and went with what he recommended for my stock original car I purchased in April 2019. He recommended a cylinder head that he works up with the lump port, a RV type cam he sells on his website, aftermarket gears. I bought the Clifford performance 6=8 kit (headers, intake manifold, carb) and that was installed first with a little improvement. The 12 Bolt stuff helped tremendously with power and overall driving.
I got an aluminum radiator, MSD ignition and distributor, Holley EFI complete kit with their gas tank, Ford 9 inch rear with 2.75 gears, 17 inch Torque Thrust 2’s and still running the original 2 speed power glide transmission. Car runs great, it’s not a race car but I can drive it anywhere no issues and it cruises and sounds great.
I’ve been meaning to do a video but it’s cold as hell in STL.
Oh and a single flow master with dual outlet. Tom at 12 Bolt is a great guy he will get you taken care of.
Hey I just came across this, super cool! What's your MPG like?
thanks for the support! before the turbo charger it would get 10-12mpg around town and it's about the same with the turbo charger. less with E85
Sweet ride man
I need help sourcing parts for my 250 inline six in my 76 C10 I want to stay carbureted but cannot find much on the 4.1L
if you are looking at a 4 barrel setup there are manifolds from Aussie Speed, Offenhauser, Clifford, to name a few
ur 76 has the cast together intake and head....a 74 or older head is required to 4bbl swap
I have a 65 with the 230 as well. It looks like it helps on the lower end RPMs for acceleration. What turbo is that?
The turbo has helped at every RPM. The midrange and top are especially strong. The turbo is a t04e. They’re commonly used for 4 cylinder cars and are everywhere. They’re integrally wastegated and I’d say for anything under 12 psi or so they’re okay for this setup. Anything past that and drive pressure starts climbing quickly
@@HunterSkiff Well it certainly looks interesting but is outside of my expertise. I do recall a Camaro on the Power Tour a few years back that ran the only six registered and it was turbo on a 250 and had impressive MPGs!
Easy to get your feet wet with fuel injection it’s the Holley setup. If you can answer multiple choice questions, you can build a base tune file. There’s a CZcams channel something like Turbo6Camaro, maybe this is the guy from power tour, I got a lot of inspiration for this build from him. I can say with certainty my fuel milage has gone way down because I can’t keep my foot out of it hahahaha
Had any problems running with stock internals? I want to boost my 292 and have gotten mixed answers
Literally none at all and I’ve had this turbo with the wastegate hose pinched way into over speed with 21psi in the manifold. Drive pressure was probably obscene too but it survived none the less. These engines don’t move air well as you know so they respond really well to forced induction. It doesn’t take much positive manifold pressure for these engines to wake up. This engine still has the stock ring gap and I’d assume you’d crack a piston long before you’d compress a rod. Having a very conservative timing curve really helped to keep cylinder pressure in check. Also keeping max rpms low helps. I don’t think this engine has ever seen more than 3600rpm because of the gearing. These engines are stronger than people give them credit for. The Holley has a lot of protections for keeping the AFR in check as well which helps. Buddy has a 292 in C10 that’s going to get twins in the semi near future so be on the lookout for that.
@@HunterSkiff awesome that is basically what I was thinking these motors are bullet proof. I just bought a 68 c20 with 4.10 gear ratio I wanna switch to 3.73. Then I'm gonna do something similar to your build except I'll be rebuilding the head then doing an offy intake with a holley 2 barrel and a 200 dollar turbo. You should definitley post a video of the tt c10
Hey are you still building this thing? I have a i6 70 that I am considering slapping a turbo on so im looking for feed back.
yes I still have the car with hopes of putting a lump port head and camshaft in this year, time permitting!
I just bought a 67 nova II with a 194. I wanted to see how the holley efi is working out for you? Trying to see if its better than the Fitech. i heard they have problems on the inline 6.
congrats on the new chevy ii. No issues with the holley sniper EFI thus far. System was super easy to configure and get up and running.
@@HunterSkiff Awesome thanks for the response.
How long will the motor last very seriously thinking about doing mine
In stock trim I’m not sure of the number where these things fall apart. I imagine you’d kick the rods out in a hurry if you got over zealous with RPM. Barring high rpm, the next thing to go would probably be the stock head gasket. I have the tune pretty conservative down low to try and keep the unknown bottom end alive. Also, the car is geared pretty tall and seldom sees over 3700rpm. That being said the car lives at 15psi of boost on this turbo, weekly, and is still running strong. Hope this gives you an idea
I have a 1979 Impala I would like to replace my V8 350 with an inline 6 will this bolt right in or will I have to make some adjustments I have a turbo 350 transmission
Not sure about the intricacies with your particular swap but the inliner will bolt to your trans
ALIAS WIZARD don’t go from an 8 to a six. The only reason people can make these old motors go is money.
A 350 v8 in a 1979 Impala is most desirable. Straight 6's work best in compact cars.
Nice car. Nice choice on the efi.
How do you control ignition? Thank you! Gives me confidence to move forward on mine
Thank you! Currently have a factory style distributor with locked out timing. Not an ideal setup, but it works. I also have one of the MSD pro billet distributors which is plug and play with the holley but haven't installed it since the distributor shaft puts the cap much higher than the OEM unit and interferes with my AC compressor, which I'm not willing to part with in South Florida...hope this helps! What's your setup?
@@HunterSkiff thanks for the reply. Mopar 225 Slantsix. Holset hx35, 500cfm blowthru carb, inter cooled. In tank electric pump. Pressure sensing fuel pump regulator. Liking the idea of efi a lot. Just not sure how to address ignition. Maybe lockout plate? Msd has the BTSM ignition, but almost 600 bucks
Sounds like you got a pretty nice setup, HX35s love inline sixes lol. If you are handy with a stock distributor and it has provisions to slow the curve as well as limit total advance, you can certainly make the factory unit work. After running Holley's EFI system I would never mess with tuning a blowthru setup again. It is super easy to install and the ability to tune it live with a laptop is worth its weight in gold.
@@HunterSkiff excellent I am sold. I think I will sell the 2300 carb as is, and purchase the efi. Sounds like worlds apart.
I will use a lock out plate for now also. Distributor has pertronix
Hey ,funny, The Holly website says that their EF I will not support a power adder. that is strange. Yet it clearly works
Nice!!!!!
Thank you!
Where can I order the kit? Comes everything needed?
The fuel injection kit is available at Holley’s website, it’s a pretty simple and straight forward install, you don’t need any special skills to get it up and running. Install took me maybe 2 hours with basic hand tools
Nice build. I'm currently building a 53 235 and I'm looking to upgrade to a setup like this.is that a 4barrel efi and how did you mount it?
the car has an offenhauser 4 barrel intake and then holley's 4bbl sniper fuel injection unit. I dont know of any 235 compatible 4 barrel intakes. That is not to say they dont exist, ive just never looked. I know there are 2 barrel intake manifolds for the 235, and Holley makes a 2 barrel fuel injection unit. Either/or would work I imagine.
Nice! Back in 1978 I built a 54 pick up with a 235 -6 It had an Offenhauser aluminum intake with twin carter YF-2100 one barrels. a Tri-Y split header and a BIG Duntov cam and flat top pistons. Swapped out the granny low 4 speed for a Saginaw close ratio 4 speed from a V-8 Monza GT and ditched the torque tube rear end for a newer pick up 12 bolt with 3:73 gears... It was really fun to drive. I would gap my best friends new 77 Trans am to 60 and be in 4th at 75 - 80 before before he went on by!
If your dad thinks these cars can’t be race cars, then he’s never seen Street Outlaws🤣
Is it backfiring or is that an exhaust leak?
It had a slight miss at idle. It was due to improper fueling when in open loop. Smooth as silk now
What size turbo?
Compressor:
Trim: 55
A/R: .5
Inducer: 50.5
Exducer: 76
Turbine:
Trim: 73
A/R: .63
Inducer: 65
That moment when you think that you’re in a Cummins truck but you realize it’s just your nova
I heard you are running 18 to 19 PSI. What is the ring gap?
Factory ring gap. I haven’t touched the inside of the engine...yet...
@@HunterSkiff Wow. Glad it's holding up.
Holding up for now. PCV looks like old faithful though lol. Cylinder temp is more critical to know than boost pressure if you’re concerned with closing the stock ring gap and killing a piston. Heat probes in the exhaust manifold would give good insight to when things are getting too warm
@@HunterSkiff That's a good way to tell.
What sniper kit is on it
this is an older, regular, base model sniper. Not the super sniper. It's the 4 injector model
We use a lot chevy straight six in brazil, 2000hp drag opala turbo
Love seeing the stuff from Brazil!!
You still pump the gas for an efi system?!
are you asking if you have to put gas into a electronic fuel injection setup?
What was the misfire from?
cold intake manifold. It goes away once the manifold warms up
Do you know where I can get the same kit you have because I got a nova too and iv been wanting to turbo it for a while ?
Which kit?
@@HunterSkiff for the turbo
I made the turbo kit myself. There is a turbo manifold from SPA but I think it only fits 66 or newer Novas. What year is your nova
@@HunterSkiff 63
yea unfortunately youre stuck making a kit on your own. There aren't any "kits" for the first generation novas, the shock towers get in the way. Wouldn't be hard with stock exhaust manifold, just make a "J" pipe and weld T3/T4 flange to it.
😍
Me Marie de tanta pinche buelta
6 cylinders are the best!!!
They're pretty cool aren't they
Yeah!!!!
How much for the build
The engine is bone stock to $900 for the Holley sniper EFI, turbo was $98. The turbo hat, piping, and boots were another $300 or so.
How has the Sniper been? Any issues?
David, an absolute dream. have no complaints. They have really made this system user friendly and easy to configure. let me know if you have any specific questions in the future!
@@HunterSkiff That's good to hear. I am planning a blow through 250 and wanted to use the Sniper but I'm getting a lot of mixed reviews.
@@davidwitcher5443 yea, absolutely no issues. the ability to plug in a laptop and fine tune the car on the fly saves soooo much time in tuning and refinement compared to working a blow through carb setup.
@@HunterSkiff You are running the standard Sniper? Not the super?
Correct it is the regular sniper model not the super. You can configure them the same
I’d love to get me an old truck with a 292 build it and turbo it
that would be a pretty sweet setup!
Is that a 65 sedan ?
yes it is!
Sounds like it has a skip at idle.
Yea good ear. The open loop idle settings I had at the time weren’t that dialed in. It’s fixed now though
@@HunterSkiff Cool. I didn't mean to insult it. I'm fascinated by power adders.
No offense taken. You have to balance idle AFR because of the fuel distribution through the I6 intake. The “best” scenario doesn’t actually occur at max vacuum
