Just got done porting my intake manifold on my 2017 Cruze 1.4 turbo. Thought it'd have those plastic restrictors in there but it actually didn't, Chevy might have gotten away from that, but I still went ahead and ported them about an 8th of an inch. Massive difference in acceleration and I have a 3inch custom cold air intake, catless exhaust, I definitely feel and hear the turbo spool alot steadier and stronger. Pulls alot harder. Thought it'd be alot harder than it actually was. Only hard part was porting each chamber exactly the same, took some time but it worked! Very happy with my gains

[@cmattdabrat]

That's awesome! Thanks for sharing. It's not often you actually get to hear about the results.

[@johnsnow1355]

I hope so unless my stock turbo car is broken is slower then a stock fiesta na ha ha

[@johnsnow1355]

The bottle brushes are genius anyone without kids never would of thought of them 😁

[@cmattdabrat]

This is true!

[@damagebrain1]

So glad I found your videos. I haven't found too many other people working on the 1.8l engines. I did my intake about 8 months ago and I had so much oil inside it. After I installed it I also did a catch can. I took my intake manifold off again about a month ago to look at it and it made such a difference. I had little to no oil in the intake. The catch can was another story.... almost 600mL of oil was in it.

[@cmattdabrat]

Hey! I had the same issue. Did you try adding a one way valve so you're not boosting the PCV system? That was my issue. I'll have to do a video on it.

[@PANTHEON71]

Now the rough surface disrupt the aero dynamics.. Now you've got all this turbulent slowing down air flow.... Molecular mayhem!

[@JoshVC]

Looking good! My throttle heater hose was also dead, must be a common issue...

[@cmattdabrat]

Thanks! They get pretty brittle. Mine has over 120k miles on it and it's a 2012. I'm just going to replace all the hoses I can so it'll be good for another 100k lol.

[@cmattdabrat]

How well do you think the stock manifold will perform with a little massaging?

[@SushiTVism]

Just to clarify, after you cleaned it, you sanded down the the openings right? Im still learning about these things

[@802Garage]

This whole step might be a little extra, but that doesn't mean we don't appreciate seeing it! Hahaha.

[@cmattdabrat]

All in the small details. A little massage here, little there. They add up lol!

[@DownwardFour]

Found a remanufactured cylinder head for the 1.8 on jegs performance, comes with springs and valves.

[@cmattdabrat]

Nice! What is wrong with the current head you have?

[@jay1185]

Hells yeah man! Interesting 1.6L intake mainfold... I never liked these "plastic" ones.

[@cmattdabrat]

I agree! The V8 Ls guys make some good power on them, if enough boost is thrown at them lol. We'll see how it does. An intake swap will be pretty easy. DBilas makes one but way too much when I could fabricate one. All in due time. I want to get the engine together, break it in, run some numbers, and see what we can improve to get it to serious power.

[@802Garage]

Plastic actually has some nice advantages. Doesn't heat soak, doesn't absorb heat from the head, holds boost just fine, lighter weight, and cheaper to replace. Despite personally loving the look and feel of aluminum more, it actually has few advantages.

[@dantekiller25]

To be honest here this engine entirely looks like a chevy version of the 93-95 gsxr model 1.8 b18c5 engine throttle body looks exactly same

[@cmattdabrat]

Definitely is! I'm sure they took a peak at one and uhh, cough... borrowed some design points.

[@zamounmohamed2494]

Hello, Since you are an experte in chevy sonic, i hope you will answer my question 🤲🤞 After an accident a part of my intake manifold was broken (chevy sonic 1.6 2013 ) It's the plastic smalle pipe on the left, so i wonder if it's secure to fix it with a glue or not. Thanks in advance.

[@cmattdabrat]

Hey! It should be okay. Just super glue it real well. Without seeing it, it's either a vacuum line, or part of the PCV. Best thing to do would be to get a used or a new one. You could also plastic weld it with a soldering iron, and some zip ties. Look up plastic welding.

[@zamounmohamed2494]

@@cmattdabrat Thanks a lot, the mechanic told me that it has something to do with the brake !!

[@timf1539]

Did you notice any improvement? Thinking about doing this to my 2.2 ecotec intake

[@cmattdabrat]

I never ran it. I ended up making a custom manifold.

[@ralphmenta249]

hey bro, if you dont reset where the variable vain plugs into the sensor exactly, it is gonna wreak HAVOC with the ECU. I deal mostly with VW/AUDI engines that have a variable runner intake and they are a NIGHTMARE if you dont delete the system while modifying your engine. The difference in butt dyno is negligible when removed. Those systems were installed for maximum output while staying within epa standards. Its not worth trying to keep it and integrate it into HP tuners. REMOVE IT I just noticed this vid is old. Hopefully you learned before fighting with the variable intake integration.

[@cmattdabrat]

Thanks for looking out! I'm ditching the VIM and have designed a custom intake. Still tweaking things, but will be on the engine soon. kzbin.info/www/bejne/gGnKindpl95gabM

[@Devo1987]

Send it to a engine repair shot and put it in hot soaker pressure washer

[@MichaelD429]

what about a bigger throttle body?

[@cmattdabrat]

I'm going to see what she can do with the mods I have already, and see if a throttle body makes much of a difference.

[@DownwardFour]

Do you have a Manual, if so how would an auto hold up in comparison?

[@cmattdabrat]

Mine is a manual. Transmissions are generally rated for torque. I'm not that familiar with the auto trans, but generally they can be machined for an additional clutch and steel to handle more power, but they all have their limited before you have to install something stronger and use a bell housing adapter. So far from what I've seen they've held up pretty well.

[@johnsnow1355]

​@@cmattdabratI am guessing u have the 5 speed. My car has the 6 speed. Maybe stronger?

[@cmattdabrat]

@@johnsnow1355 Hey John! It's the 6 speed.

[@anthonyjulson8840]

I'd also be careful with the transmission in your car. 2011 and 2012 weren't good years for the cruze transmission.

[@cmattdabrat]

Definitely. There's an upgraded case cover that came in later models that have larger bearings, and better oiling. I may sort that out with a trip to the scrap yard before it all goes back together.

[@anthonyjulson8840]

@@cmattdabrat the 11-12 transmission is almost impossible to find in good shape. I wish you good luck!!

@@anthonyjulson8840 Mines has been babied and in good shape. Worth building up.

[@MrJ-wrench]

😂😂😂😂 new EGR valve

[@cmattdabrat]

LOL, yeah, I realized I was calling it the wrong thing later.

[@DiamondNedFlanders]

Is this similar to the 1.4l?

[@cmattdabrat]

The 1.4 doesn't have the variable runners, and porting could greatly improve the performance because it has "tumbler" walks that could be ported out so it has a straight shot to the chamber.

[@DiamondNedFlanders]

Matthew Chevalier do you know of any video of someone doing that?

[@cmattdabrat]

@@DiamondNedFlanders I don't but if you search, you can find forums that have pictures. Wish I did, but maybe a future video in which I'd have to pull one from the wrecking yard.

[@anthonyjulson8840]

That wasn't an egr valve. The vvt on the 1.8 makes it so an egr valve is not needed.

[@cmattdabrat]

Might not be an EGR. There is an emissions system though that hooks up to the intake, and runs to the gas tank. I'm not a mechanic. In your opinion, what is that type of system called?

[@anthonyjulson8840]

@@cmattdabrat that's the evap purge valve. It helps keep the fumes from the gas tank under control.
