I recommend getting an upgraded radiator and address the cooling system before u get problems u don’t want. These cruzes are notorious for having cooling system issues. Imagine it with all these extra accessories and upgrades. Good to see ur getting ready to address these issues.

[@cmattdabrat]

I hear that. The main issue with the 1.8 is just the plastic hose that goes from the thermostat to the throttle body, which I've eliminated. Aside from that, only issue I've had was just not paying attention to the fact the fan was touching the down pipe, so it wasn't able to run. The stock radiator has been working really well.

[@nicholasgarulle1947]

Cooling issues have nothing to do with the radiator. It’s the thermostat housing that creates all kinds of issues. Deleting cats and running a larger inter cooler and wrapping the manifold I bet the engine is probably running cooler overall to begin with

[@Slo_300c]

Can’t wait to see it on the dyno ! Great video

[@cmattdabrat]

Thank you! Wont be long.

[@L3XURIOUS]

if you want stealth, i think you should make the exhaust quieter aswell

[@cmattdabrat]

Forgot to add that, but have a 3" FlowMaster FX muffler that'll be going on to help tame it some.

[@L3XURIOUS]

@@cmattdabrat hopefully some of the rasp will be gone

[@1234567890CAB]

You should definitely should wrap the manifold, not just for engine bay temps but also because it directs more heat into the turbo and heat is energy. Possibly also look into getting the manifold ceramic coated inside and out too.

[@cmattdabrat]

Great point.

[@johnsnow1355]

I dunno I had a turbo manifold crack in half on me the minute I wrapped it when unwrapped it was just fine. The wrap trapped in so much heat it was glowing red and actually almost started the wrap on fire. Turbo make so much more heat then na engines.

[@BabyroqueTV]

I have the injection intake , and whatever temp is out side weather, the air temp going in is only 2-3 temps up, compare to other intakes close to the engine gives more than 14-up temps higher than temp outside

[@cmattdabrat]

Nice! I've seen those and they look like a good setup. I believe those actually have the air filter in the wheel well right? Which I've thought about gettin the filter into the wheel well. My only concern is we get heavy flooding in our area more often than I'm comfortable with. Lost a car years ago to a cold air setup that just sucked up water on a rainy day.

[@BabyroqueTV]

@@cmattdabrat yes , since it’s two piece , you can remove one and have the filter safe when it rains, that’s how I found out how my air temps changed. It’s worth it 👌🏻

[@Vuhjayjay68]

Love the videos

[@cmattdabrat]

Thank you!

[@johnsnow1355]

Hood vents will be dumb if u want the car to stay cooler under the hood have the radiator fan on a timer so it runs for a few minutes to keep air flowing when the motor is off. Upgrade the battery there is tons of room in the battery tray for a big lithium battery that will run the fan for hours with ignition off.

[@Davsoto120]

There are some intake pipes that let you feed the intake Into that hole, then combines with the fog light vent, it’ll give you decent cold air

[@cmattdabrat]

You're right about that. I have the stock intake piping which actually runs from the front of the car to that opening. I might just install that as well to get cool air from the upper front of the grill towards the filter.

[@johnsnow1355]

​@@cmattdabratwhatever u do always have the air filter Intake higher then the bumper impact beam or in a Texas flood your going to hydrolock it.

[@dakotajones8010]

heat extractors work wonders on my 14 mustang gt on cold mornings when shes hot u can see the hot air coming out of the extractors

[@cmattdabrat]

Cool. Will definitely look into it.

[@8SecSleeper]

I'm hoping the WOT box you bought supports pulling timing while activated. I hacked the firmware on my saab to do all that without an external device and when I didn't pull timing it got knock, instead of nuking my timing tables in two step range. I just modified my firmware further to pull timing while 2 step or NLS was activated.

[@cmattdabrat]

It doesn't support pulling timing. Just an ignition cut. What we'll have to do is pull timing in the area where the two step and no lift shift is activated. We'll see what it likes in those low load areas. Just pull a little at a time to build / hold boost.

[@802Garage]

The joys of a little engine bay. All sounds like a good plan to me!

[@cmattdabrat]

Tell me about it! Everything was tight even before tossing a humongous turbo between the radiator and engine. lol

[@arashtorabi8852]

Hi Matthew keep a extra radiator hose in the trunk because it's too close to the headers

[@cmattdabrat]

Might just make the portions that are closest metal, but you got a good point.

[@jeffboyer8214]

Hi Get the fog light part and a 3 inch pipe with a bend up the the opening but do not attach it to the filter or intake pipe in case you run into deep water. Vents for the hood look for a 3.4 twin cam lumina from the 90s they had some Vents in the hoods you may find them in the u pull it yard. For items getting hot 🔥 you may need some heat reflecting tape or ls spark plug boots to cover your wires once the plastic tubing is fixed. As for the plastic push locks & plastic tubing you could go with aluminum tubing once you get all yout lengths correct & maybe able to pull it out as a unit if it's possible. I thought you wrapped the header when you installed it ? I must have missed something. Good progress for sure & dyno tuning is going to be a blast for you. 400 to 440 hp. @ 23 pounds of boost ( this is a lot of boost ) & tq should be 320 to 350 tq. As always just my thoughts & be safe team.

[@cmattdabrat]

I appreciate it Jeff! Thanks for all the tips and thoughts. Looking forward to seeing to final numbers.

[@remixfla954]

God bless you for holding on so long, know your wife is looking down on you happy as can be free of pain, guardian angel until you make your steps to heaven but live your life bro she would want you to be happy, so keep building cool shit! And definitely know she looks like the type to say starting dating she wouldn't want you alone, good luck bro and thanks for the rad videos.!

[@cmattdabrat]

I really appreciate that.

[@justingick9371]

If you don’t want to cut into the hood could put spacers where the hood mounts to the hinges to lift the rear of the hood kinda like a cowl hood.

[@garyhowe88]

No has the opposite effect to what you actually think it would.

[@cmattdabrat]

I don't mind cutting the hood. She's a little banged up from one of the last times I was pulling the engine. Left an easy up out and stormed that night, in which I came back to the shop and it was across the parking lot and banged it up a little... plus Shannon sat on the hood years ago lol. Hard to see on a white car, but...

[@sosemiteyam562]

@@cmattdabrat Oh my xD. Great start to that morning eh? Just rollin' with the punches, keep it up bro :D.

[@trustme7660]

I have the 1.4

[@cmattdabrat]

Sweet.

[@davesworld2132]

Hey what’s up. Hope all is well. Question. What are you running to evacuate crankcase pressure?

[@cmattdabrat]

Hey Dave. ATM, I just have a Motion Raceworks single port 12an catch can that vents to atmosphere. Has been working wonders. It's hooked up to the stock PCV from the cam cover. Even at idle you can see it going to work. I'll do a video on it in the future, but it catches all the blow by. Comes out pretty clear and has been working really well. I took that idea from what the guys with the 1.6 VXR's overseas. Rather than routing it back in front of the turbo to burn it back off, which in time just ends up gunking up the entire intake system. I also did away with how the stock throttle body is setup, in which the PCV was setup to pull crankcase pressure from the PCV port behind the throttle body for emissions. I have a LSJ throttle I got from ZZP that does have the provisions for a the PCV, nor the coolant pass through because I don't really need that here in Houston. Rarely reaches freezing during the winter to justify it.

[@davesworld2132]

@@cmattdabrat wow that’s some crazy blow by! BTW I’m catching up on everything with your build. That’s why I keep asking questions if you’ve done a video I may not have seen it yet my apologies. But on the volume of boost you’re running did you have to open up your gaps on your piston rings?

[@cmattdabrat]

@@davesworld2132 I probably skipped over it just trying to get things buttoned up. I believe I installed it during the time I was working on the custom intake, and intercooler piping. Those were huge tasks vs a 5 minute install lol. But I'll post something on the subject soon to show how well it's been working. Yeah, the rings are gapped for all the boost, and nitros. It'll be interesting to see what it does once on the dyno. I know the ZZP Sonic is a similar setup and you can see the vapors coming out during a WOT pull.

[@davesworld2132]

@@cmattdabrat love it. By the way you’re so right. It’s so hard to choose what to show the public. Sometimes those little five minute projects we are proud of but the big stuff is what everyone wants to see!

[@cmattdabrat]

@@davesworld2132 A lot of truth to that. I'll do a video in the future showing the results of the setup. Posting a video of the install without results isn't very interesting to me anyway. Now to show, here's the catch can, and what it's actually doing for the car makes more sense.

[@mastercricket7626]

rad bro n for heat evacuation i made a cowl hood for my build but also u can do hood spacers like the honda guys do it does help n stays low key if u dont know what they mean when u see hood jacked at back lol ... keep on with it bro u doing it and the cruze is rad imo bro just takes time for perfection lol l8 bro stay rad n build on 💪 ✌

[@cmattdabrat]

Nice. It wouldn't be too hard to cut the hood, and extend it a little to make a cowl. Just weld in the standoff portion, and repaint the hood.

[@mastercricket7626]

@@cmattdabrat yeah not bad at all bro onlytook me cpl hours to get it to the shape i wanted with the cowel n now i just deciding if i wanna use it as a mold for fiberglass or carbon fiber or if i wanna wrap it were its aluminum lol decision decisions .... but yeah u got aluminum hood to right? so regardeless it already pretty light if so n u gor the skills for sure on the welding to make it look way rad bro ... n e ways peace n love bro stay rad and build on...

[@djinkentertainment]

you're stealth approach goes out the window as soon as you turn your car on and step on the gas pedal my man hahaha 😅

[@cmattdabrat]

Truth to that, but we'll see how the FlowMaster FX tames the sound down. No one really looks at the cruise and thinks, this thing is worth running. Just another 4 cylinder with an exhaust.

[@djinkentertainment]

@@cmattdabrat Haha well that's true, right up to the point the big wheel turbo spools up and they get gapped haha 😆

[@wiliboo6843]

Do this to my cruze 😩

[@cmattdabrat]

I may offer services in the future to do builds. ATM, it's all just for fun.

[@CalebGibbsAvenue]

Is there a reason you didn't go with a supercharger.

[@cmattdabrat]

I think superchargers are cool. It's nice having no boost and getting the fuel economy that comes with a turbo when cruising. Almost like having nitros when the turbo kicks in at higher RPMs.

[@QDArt-gj6lb]

The Cruze forums have a lot of diagrams and manuals

[@CalebGibbsAvenue]

Is there a reason you didn't just take it to the Dino the first build. I figure you don't want to spend more money on something that may not work out as Well. proving that it will actually take the boost first. My cuz blew his up but he never tooned it. I thinking timing was his first problem. So glad to see this bild come out good. Im thinking you get 250hp out of it. Focus ST where pushing 270- 285hp 2.0L tooned

[@cmattdabrat]

You nailed it. It'll cost $700 for the dyno tune and session. I want to make sure it'll live before hand. I know enough to tune it, but to get an expert that tunes for a living and to use a dyno as a tool to get the most power out of it safely is the end goal. It'll be fun to see what it does. Looking to push it to around 25-28 psi of boost.

[@2strokesimdone833]

Before you chop the hood up give some hinge spacers a shot to see if it's not too terrible to look at. Your engine bay is going to stay filthy with open vents on it. Not to mention if water gets on that wrap it's going to destroy it quick. Great content brother, one of my favorite automotive youtube channels. 👌

[@cmattdabrat]

Definitely considering all my options.

[@johnsnow1355]

If u break the seal between the hood and the wiper cowl all u will smell is oil and crankcase fumes from the breather getting sucked into the HVAC system because your intake is built into the wiper cowl for all the air u beath in the car. You don't have a vacuum on the breather it's just vented to atmosphere so I gautentee your gonna feel sick after awhile breathing your cam covers fumes inside the car.
