Just a quick update. Working on tuning the car, or learning how. Idle dialed in, but working on getting the car to not run lean and have some drive ability. I have my boost gauge and wideband installed as well in a zzp style pillar. Got a blemished one pretty cheap.
What is that with the Mercedes emblem on it?

T04E....**** that's a **** ton of air for that car. LOL I'll have to watch your videos now, looks like you've got a cool solid little budget project here.

LOL, you may be right about that, but it'll make for some good fuel economy under 3k, and some power when I want to rug it.

Thus far I have about 600-700 in parts. HP Tuners has been the most expensive part of it all. Easy the same cost as all the mechanical parts. I have at least 1.5k miles on the eBay turbo as a glorified hair drier, so can't complain about the quality of the Chinese turbo.

Quick update. I'm finally to the point in tuning where I'm safely building boost! 9 lbs is when the waste gate kicks in. She doesn't like much timing at all, but I have it pulled back to keep things safe until I get fuel completely sorted out. Then I'll take it to my buddies shop, toss it on the dyno, fine tune the fuel and see how much timing she likes with that 10.5:1 CR.

I'll post some quick short videos soon as I'm giving you guys the "inside scoop"...

This is coming along really nicely. There have been many waiting for someone to do this succesfully. I think you may be the one.

When you install the gauges, if you are going to use the ZZP piller pods, be carefull with the removal of the factory one as the tether can give you issues. If you have not seen one yet, my tutorial on the installation of the pods has some decent pictures of them.

I also had a slightly bent post at the top of my pillar that gave me fits. Don't believe this was any fault of zzp. The whistle is nice... :cool::cool::cool::cool:

Thank you! Hahaha. This is true. Probably one of the reasons I've waited for a while to do it, but I figured, might as well go for it. That's the whole reason I got the 1.8 with the manual.

I am! I purchased a blemished one to save a little money. Thank you! I have actually read your write up and will be very helpful.

Thank you! I'll have a video up soon of installing the pillar gauges and the start of tuning.

Okay, so you guys are getting the inside scoop. I have my gauges installed, and started tuning. Just to get the hang of using HP Tuners I left the charge pipe off and kept the stock air box. Tuned the MAF sensor, everything has been going well. Added the charge pipe, and the MAF sensor is out of range. So I'll have to rethink my intake pipe situation. I could do a MAF delete, but I would prefer to have it because in Houston we go from freezing to a swampy 100+º's during summer. It's summer, so I'd like the MAF to do the work to keep the AFR / lambda spot on.

Because I'm still learning, in which I'm on HPTuners forum, I'm trying to figure out how to scale the MAF. I've gotten some replies, but for a noob it can be a little confusing. So switch the car over to running strictly off of the VE table.

The next thing I quickly ran into was I ran out of map sensor, so I got a 1.4 3 bar sensor and scaled my MAP. Tuning the VE table has been pretty straight forward. I have her pretty dialed in, and went ahead and put e85 in. She's running even stronger on e85.

Before I mention some of the issues I have been running into, I just want to note I have been slowly moving towards boost. Keeping the RPMS low, keeping an eye on my KR, and lambda. I've been logging my drivability as I would normally drive keeping things out of boost. Light throttle kinda stuff. Dailed in. Now were moving to boost. I've got the car into waste gate pressure. The highest it's logged has been 9 psi, but it generally kicks in around 7-8 lbs of boost. BTW, she pulls nice!

ISSUES...
1) What I have been running into, is more than likely an improper crankcase ventilation setup. Now that I'm getting into boost, I'm getting oil spray everywhere. The longer it stays in boost, the more oil shows up in my engine bay.

As you may have seen from the videos, I have a bung coming out the back of the intake, to an oil catch can, and back into the intake side of the turbo inlet. BIG MISTAKE. I'm getting oil shooting out of the catch can, and there is some oil in the entire system. So that'll require some cleaning out. I did give it a try with a baffle, used a piece of hose and a hose clamp to see if perhaps the camshaft has just been tossing oil into the bung. No success, and still having the same issue.

I've looked at how the 1.4 is setup, but unfortunately it doesn't do me a whole lot of good because the 1.4 intake is designed with an additional port to pull the crankcase pressure. Although the check valves seem to give me a little clue as to what I can try.

My question is, and after research without any real clue as to the best way to setup the crankcase vent for the 1.8, what ideas do you guys have to properly setup the crankcase vent on this NA motor? I'm stumped at this point. I'm going to ask on a turbo forum, but I'd figure you guys are pretty knowledgeable.


2) Plug selection. I ordered a set of colder range plugs, tried the gap initially at .30. Got a little spark plug blow out in boost, but this was after the intake side of things already had oil in it. Let's just say I fouled a couple set of plugs already.

I bought a set of 1.4 plugs, colder range, gap is .28. Once I get the oil catch can situated, what plugs would you recommend? A buddy of mine, mechanic by trade, said to give a set of plugs that doesn't have the tiny point, can't think of the proper name at the second.

I'm thinking the stock style 1.4 plugs should be fine? Any help or suggestions in this area would be great.


3) Once I scaled the VE table for the 3 bar MAP sensor, my timing tables are out of wack, and really only running on one column of the timing table. I scaled up the grams of air with no success. I'm still only getting data one row. I'll check with the HP Tuner guys, but I'd figure I'd ask here just in case because we are talking Cruze specific and this is uncharted or undocumented territory for the 1.8.

4) Lastly, I'm not really seeing any options for an upgraded coil? Looks like I may have to stick with the stock NKG setup. I'm going to reach out to ZZP, and see if they have any solutions, but we'll see.

Thanks for you time and feedback!

.Do you have a check valve installed?

Does the 1.8 have a coil pack like the 1.4?
I'm not sure if the coils are fired as a waste spark system (all coils), 2 coils at a time, or one coil at a time. A wiring diagram might shed a little light. Probably could do a ls7 coil setup. The harness might not be to hard to make.

I don't have a check valve installed. Does the check valve work close under boost or when under vacuum?

After doing a little research, I saw the LS7 setup. Looks pretty cool. Are the LS7 coils stock units that could be bought for a reasonable price? $500 is pretty pricey for the MSD style coil, but I guess that's the price you pay to get a better setup. This project is starting to quickly go from a budget build to $$$ lol.

The 1.8 has a four-plug unit like the 1.4T, but the spacing is a bit different as I recall (ie - they're not interchangeable).

On the 1.8, there is a separate wire from the ECM for each coil, so there's no need for wasted spark. That is, I assume the oomputer fires them all separately. But I know, some of the V6's used wasted spark - each coil (transformer) fired 2 cylinders simultaneously.

I've attached a schematic for the 1.8 ignition (2013).

Talk to @RoninDusette, I think he has done this.

Can you post some sort of diagram of what you did? Just recently Ronin asked about this. The tiny bit of info I found kind of eludes to the fact that it is very similar to the 1.4 in at least function, if not form.

As you may have seen from the videos, I have a bung coming out the back of the intake, to an oil catch can, and back into the intake side of the turbo inlet. BIG MISTAKE. I'm getting oil shooting out of the catch can, and there is some oil in the entire system. So that'll require some cleaning out. I did give it a try with a baffle, used a piece of hose and a hose clamp to see if perhaps the camshaft has just been tossing oil into the bung. No success, and still having the same issue.
I am pretty sure the catch can belongs in the PCV circuit

Thank you. That's very helpful. I'll dig into what it'll take to put some on in the near future.

Thank you! I'll post a diagram a little later tonight. After doing some research I think I might have a solution figured out. I'll be sure to reach out to see if he can guide me in the right direction.
