Big Zeus Build Thread

Ok, after a long period of contemplation, I have decided to go ahead and make a thread documenting my 2013 Cruze LT 1.4L. I will name it a build thread, but don't really consider it that. This is just something that I work on and improve as time and funds allow. I like to tinker and find different ways to do things as well as maximize performance. I do all the work in my enclosed garage and have a decent amount of tools. Most if not all of the modifications will be bolt on.

And the story begins:

When she was pretty new, she was full of swirl marks and scratches. This is after a professional paint correction that I did myself with the pictured Meguiars and harbor freight DA. Tons of work and it took days. I went panel by panel.


Next, got some new shoes (Continental Control Contact) These things are great, so much softer than the old Michelins

Shortly after, it was time to start fixing leaks. This was the first one, I fabbed up a piece of rubber tubing and put a heat shield on it. It has lasted almost 2 years now with no leaks.


Had a transmission fluid leak that was likely from an overfill, did a drain and fill X3 with AC Delco fluid.


Next was a rich condition, which I finally narrowed down to the cooler NGK plugs I installed, Don't go with the 8's... unless you like unburnt fuel

Next up is oil leak time, the oil cooler and pan were leaking. The dealer fixed the pan and for some reason painted it all with silver spray paint... I did the oil cooler a month or two on my own after. More to come in next post

Did some paint removal from the oil pan today, its a heck of a job... the dealership did this a few years ago. I used brake cleaner and scotch brite pads. This took almost a whole can... If anyone has an easier method I am listening! Quite a bit of elbow grease, but got most of the front done and bottom.

Paint removal? My oil pan is unpainted aluminum...
Yes, as it says in my post the dealership gave it this paint job last time they resealed it, or didn’t reseal it. 🧐 and yes a GM dealership.
Oops. I must not be able to read today.

That's malicious. Did you report them to GM?
Nah, got it all over the axles, frame rails, tranny as you can see... No clue as to why they thought it was a good idea.
I’m embarrassed to say how many cans of brake cleaner and elbow grease it took. But the deed is basically done!

For all the brake clean lovers

Ok, finished the oil pan cleaning! What a pain. Also reinstalled the heat shield in preparation for the new BNR heat shield cover that I am going to order soon as well as wrapped the rest of my coolant fix hose. A bit ugly, bit it works and is protected!

I have also now completely ditched the Forge wastegate actuator and sold it. It pulsated almost all the time, the ZZP/ebay knockoff one is just smoother. Now when I accelerate there is no pulsing. I also adapter the Forge atmospheric BPV to my ZZP V3 turbo. Missed the sound :cool:

Installed the BNR Heat Shield today, very good quality and a perfect fit! I would highly recommend it for the price and it also comes in other colors, although I chose natural.

Check out the pics here:

Does that thing go ober the existing heat shield?
either Or. You can choose!
I can't choose. I don't think it'll fit in my engine bay. But other people can. :LOL:
That turbo almost has to touch the hood, yeah? Side note, do you know where that GSP intake adapter came from that you shipped with the v3?
Got a new key fob today and moved the key over to it. The range is still an issue, or maybe it's user error... When I walk away and lock the car, it locks once, but when I click again it doesn't do anything immediately... to beep the horn and confirm lock. Maybe I don't need to do that?
When you press lock once it locks and a few seconds later turns on the alarm.

I actually just lock it with the door switch most of the time. I know that the earlier Cruzes have a different door lock location on the dash.
Interesting. So no need to double lock then?
In the never ending quest to search for less plastic parts I have uncovered this. I am going to compare it to the original tonight and give it a test fit.

Ok it didn’t fit. I may try to mess with it some more at a later time. This fit though! Although it was very tight.

Fairly certain it was an Ebay purchase though mine didnt have the "GM" packaging .. have you measured OD of both caps at the threas and compared the threads ? checked to make sure there wasnt just a knick or something holding it back ??
Yeah, even worked on them a bit with a dremel, no dice.
I am still around, still got the Cruze, no big updates to share really. Washed her up today and did a quick ceramic wax. Hit 60k miles.

I have one of those. Fits like a glove.
Care to share the link where you got yours? I had to go back to plastic… Never got one that would thread in sadly

Where did you have that done? I have a key fob, but cant get the old one open to switch the guts.
I did it myself, used a metal pry tool that is used for mobile phones to split the halves apart.
Can you post a picture of or a link for it?
Sure, this is it! Best Metal Spudger Tool for Pry Separation Screen Removal Open Cell Phone Repair | eBay

Use that dang thing for so many things. It’s pretty handy.
