Finally got this flywheel situation sorted! So ready to get her back on the road and have some fun!
Can’t wait to see this car ripping down the roads! Keep up the good work man!!!
What's the pn on those bolts? I just bought a set of arp flywheel bolts but it came with 7 bolts and i only need 6 lol they're the same size/ pitch as these lol
You have had a lot of rough luck with your build but I must say, your not one to give up. I'm impressed with your determination and drive . It's inspiring 💛👍
I appreciate it. I'm definitely driven to see what this engine is capable of seeing as most mod the 1.4 because it already is configured with a turbo from the factory.
@Matthew Chevalier the project is very innovative and will help many in the future with mods that need done with your application. Very valuable info in your vidros
Can’t wait to see the abundant fruits of your labor.
Thanks Nate! Me too.
All about the DIY and saving money!
Heck yeah!
Nice
Thanks!
You got this Matt. Woo! If I were on a quest to kill a dragon I want you on my team.
That's probably the best compliment ever!
Awsome idea Matt thanks for sharing hi from P.R. 🇵🇷🇵🇷
Glad you liked it!
Hey! Awesome I actually caught the video early today!
Awesome!
Video #3 of stating what I would do with the turbo. REAR MOUNT COLORADO BAAAABY
Hahaha, would love to see that!
GT35.
I always DIY. One time I hand polished my crank journals. Worked out just fine
Awesome! A lot can be DIY'd if you have more time than money... or don't want to wait for slow machine shop turnarounds.
With the 2.4 Ecotec I've put 320hp through the stock bolts (6 bolt) and with ARP bolts I've put 400+ hp through it many times and taken it apart, a lot, never noticed an issue. The LNF 2.0 turbocharged engine uses the same bolts, except there are 8 bolts instead of 6 bolts.
Looks like the first time around, the manual I had had the wrong torque specs. So they were over tightened.
can smelt those old ARP bolts mixed with SAE9000 into a calendrical bar, inside of a argon purged electro magnetic sphere... but machining it also requires heating in very hot within within a similar vacuum purged argon filled chamber. Remote CNC, that's why its $300 a bolt. "the initial manufacturing set up cost has not been found as profitable to public use" there are not any drill bits that can cut into that metal. primary use in large locomotive/agricultural engines, the crankshaft is ARP4000
I hear that. I'm not knocking their reasoning behind the price per bolt. As a small business owner, we don't screw with small custom orders (t-shirts) that require a lot of setup time. Just wanted to put it out there that I reached out, and here's what the price is. Nothing available in the Cruze / Sonic 1.8 / 1.4 size. So if you're looking to upgrade, you'll have to come up with a solution.
Buy some left handed drill bit they'll catch and run the broken stud out ...your welcome 🇺🇸 thanks for sharing
Have to give that whirl next time I need to pull a broken stud / bolt.
Man you are a champ you don’t let this thing knock you down lol mine almost got me a few times but I’m still going
I hear that! Don't get me wrong, every setback is a slight blow, but we're not going to let it hold us down!
You make the best content with the best attitide. Keep it up and thanks!
Thank you! I really appreciate it!
Gt35 I own a white Cruze eco 1.4 6 speed it’s dope to see someone document their build like this and im planing to do a big turbo setup as well. thanks for posting your Cruze content makes me feel like modifying my Cruze is possible
That's awesome! I'm glad it's inspiring you.
Gt35 awesome video !
Thanks!
Gt35 ftw and love the uniqueness of this build always look forward to these updates
Thank you!
Gt35. Great content. Excited to see the finished Engine.
Thank you! Looking forward to it.
Man o man I'm glad to see you didn't lost your nuts lol.
🤣 It's all fun and games until some loses their nutz.
GT35, I love your content bro
Thank you!
Since this crank was a auto transmission engine it looks like there is no pilot bushing to support the input shaft?
Oddly enough, I haven't seen a pilot bearing in either of the cranks. Don't think they came with them. Have even searched in the parts manual / diagrams. None to be found / seen.
I would have figured those were blind holes in the crankshaft. That’s a surprise
They're through holes. I had to be careful to not get too much shavings in the pan and not to start drilling through the rear main cap.
Gt35 for my cruze
I'm betting 1 shiny shilling the engine blows up
I hope we can get it to that point lol
I have got no idea why you went at tapping the flywheel as the threads would not match the cranks. Kinda disappointed in your thinking Matt. It was a he'll off a job drilling and extract the old bolt I can imagine , that would test your patience for sure buddy. Nice job and well done mate.
Thank you. I only tapped the one hole, just to hold it securely in place while I drilled out the crankshaft. I drilled the flywheel holes slightly larger afterwards. As I was editing the video, I thought I'm probably not explaining this very clearly, but we got the job done.

That snail would look really good on my blobeye wrx lol
lol! Love that era. Almost bought one when they came out. Just didn't have enough credit at that time.
Daam what a bummer! I would have been sooo sad lol.
@@jhanTheman lol, yeah, definitely didn't leave the dealer feeling stoked.
Gt35 ftw
Great video man, how's everything with your wife or girlfriend with the liver issues?
Thanks for asking. She has her good days and bad days. Still not completely out of the woods but she's getting there.
Lmao I literally can’t wait I wanna hear all the turbo noises that thing is gonna make, also interested in how well the stock 1.4l will like the BIG TURBO. As always great video Matt!
(Gt35)
Thank you! Sooo ready to play with the car on the road some more.
The 1.4 is slow no matter what u do 😂
@@johnsnow1355 I was wrong it’s 1.8
G35!!
Hmmm if u watch your channel playlist from start to finish your built engine videos show as being posted before these videos of the temp engine build.... Now I'm all confused if these videos are actually older then the videos of the fully built engine being built and installed.....
That's odd...
I am buying a 2012 chevy Cruze in the next week that needs a head gasket, I found a kit that he head studs and the gaskets, is there any bolts I need to order that are one time use
If you're just changing out the head gasket, the bolts are the only tty I can think of.
However, some other notable mentions that are tty is the balancer, piston rods, main cap bolts, belt idler, timing belt idler, camshaft gears. They do say to replace the front engine support bolts that bolt to the head and block, but I've yet to find any. The rest for the most part are reusable. So parts do need the threads cleaned and blue loctite.
I still cannot believe bolts that can handle a clutch drop cannot handle whatever torque it was making at over 7000RPM. Were you data logging and if so, how much boost when it let go?
Edit: Also what was the belt issue?
I'm surprised too because it's the same bolts in the 1.4 and don't think the guys at ZZP have twisted theirs out?
I was data logging. I actually was doing a 2nd gear pull, and logging only that pull to dial in the top end some more. It was making 13 psi and some change, but I also ran it out to 8.2k rpm and when it bounced off rev limiter, that's where I heard it let go.
Oh, on the belt. Just the dumbest oversight....ever. When I got a belt from Autozone, they gave me the correct belt, but the diagram they kept pulling up, was not the correct routing. It was ass backwards. So I thought the belt was too short, and kept try different length belts. Longs story short, had to look up a video on TH-cam and light bulb moment... now it's setup correct. 🤦🏽♂️
Why did you tap the flywheel for thread ?
To install larger ARP bolts because the stock bolts broke off.
@@cmattdabrat But the flywheel doesn't need thread ? Only the crankshaft.

Got any chatter from the flywheel?
With the clutch, pressure plate, and trans in, and the car in neutral. Definitely chatter. As soon as you press the clutch in, it goes away. All part of switching the a SMF, but not that big of an issue to me.
@@cmattdabrat mine also got one even with the balancing so close to true weight🤣
Gt35 lol i will need 1 more
Will get you half way there! lol
I wouldn't have done it any other way either 🤷
Thanks!
Great job with the "beater" engine 👍 you make really entertaining videos!
The more I think about this the worse it gets. So bolts in this instance provide 2 forces clamping and shear. The larger bolts may produce larger clamping force although if they are at the same torque specks then they may even produce less. The larger diameter should provide more shear force. However, since they are drilled by hand the shear could be on one or 2 bolts at a time instead of all 6 at once. Precision-drilled pins between the bolt holes would provide more shear force without enlarging the bolts. Video on how larger bolts doesn't mean the same clamping force. data starts in at about 4 minutes. th-cam.com/video/rGv_UXhNORE/w-d-xo.html
Thanks for sharing and you have a valid point. I'm not loosing sleep over it, nor should you. This is all just a fun project, and seeing what works, and what doesn't.
Having said that, what boggles my mind is the fact the stock bolts sheered. Many have ran the same bolts (they are also in the 1.6 A16LET, as well as the 1.4 LUV) without issues. When I installed the flywheel, I torqued them to 45, 120º, and 45º. Don't quote me on those degrees, and I'm wiring this up off the top of my head and refer to the 1.8 manual for everything.
So my question is, is it because of the flywheel being aluminum (softer metal)?
Based on that video, the smaller the bolt, the more clamping force due to less friction. Which makes sense. Sheer force I'd like to see. I understand where you're coming from with the precision drilling or lack there of. However, this video could still be useful for anyone that has, let's say one bolt that needs to be oversized due to a stripped thread. It's fairly common for something like that to happen and common practice to enlarge it to the next size, helicoil it, etc.
TBH, not sure how many people will read this, but I put about 50 hard miles on the car, many pulls, and same issue came up. So I will be pulling the trans, and crankshaft. Installing a stock crankshaft without modifications. I have a billet steel single mass flywheel on the way to put this issue to bed so we can get to breaking the next weak link.
If modding this platform was easy, everyone would be doing it. By documenting this experience it'll save a lot of people the setbacks, time and money.
I appreciate you looking out, and sharing your thoughts. It'll definitely help this project succeed, which I know we all want to see.
@@cmattdabrat Just figured it was worth mentioning for the possibility of others considering this and since it sounds like you plan on building another motor. I researched strengthing the connection between the crank and flywheel and was seeing recommendations for precision pinning. I definitely understand the fun project Half of what I do is let's see if it will work. Granted I have a small machine shop at my disposal.
"GT35"
😂😂Again not on right torque 😂😂 I hope it will work great and this little detail is killing me in every project 😂😂
lol, at least I'm honest about it.
@@cmattdabrat yes I know you that and it's a real life you are showing some time things not going well but I like your work and not giving up keep up good work
@@arashtorabi8852 I really appreciate it! Definitely going to see this through. Took me 6 years to put a V8 in the front of a classic vw beetle. This is a walk in the park by comparison, aside from SBC being so easy to put together and lots of support for them. Let's do this!
@@cmattdabrat ya I see that beetle nice job. Some people think the project must end in 3 months it's not possible with work and the family at home . I'm working on project for 6 months and it's 40 percent is complet it lots of effort and energy. I hope you can finish yours soon. Wish you the best 😉
I know i commented in the last video
But if i win that Sexy ass Gt35
I think it would go on my buell
Not the s10
Hell yeah!
Tap dat (single) Mass!!! (Flywheel)..... In all seriousness tho, all those shaving in the rear main seal....... Ughhhhh...
I'm sure it'll be fine. Just a junkyard engine lol.
