1.4 turbo?

14 posts in this topic

Hi I'm doing some research about turbocharging the spark and today I took some pictures of the 1.4 turbo ecotec in the 2017 cruze. I think it might just bolt on our engines next would be engine management I guess, I'm not an expert :)

The new cruze 1.4t has an integrated exhaust manifold like the spark

Bolting the turbo is just step one... that can easily be done with an adapter plate if it does not directly bolt on. You will need to figure out cooling lines, charge pipe, intake, intercooler, fueling, and tuning. But still sounds like a fun project.

The turbo on the le2 does not bolt on to a manifold. It may even bolt on straight to the lv7 head for all we know.

I believe the 1.4 block/heads are the same but the pistons and crank in the turbo are forged vs. cast in the NA engine. The higher compression cast pistons in the Spark would have a short lifespan if force fed. Without swapping out the cast parts for forged it would run but for how long under full boost until meltdown/breakage is anyone's guess. Would probably be much simpler finding a totaled cruze for cheap and doing a whole engine/computer swap into the Spark.

I'm trying to do what you are describing. I have a 2014 chevy spark and I'm working on putting a 2016 chevy cruze turbo on it. It's definitely not "bolt on" ready. I'm enjoying the project so far though. Hindsight, I would probably look for a universal turbo due to the flange shape and sizes. No major complaints yet though.

I know this is an old topic but my wife just got a Trax with the 1.4 Turbo and it seems (keep in mind I'm a computer guy not a mechanic), the engine mounts and everything are exactly the same in the 2018 Trax 1.4 Turbo as they are in my 2017 Spark 1.4.....seems like that would be a much easier swap.

My wife has a '17 Trax, and I ALSO work in IT... what a coincidence.

 

The reason the mounts are the same for the Trax is that it's built on the same chassis as the Spark (Sonic too). The Trax engine however is a different family, meaning you'd have to figure out all the myriad of things that are different vs. the Cruze motor which is roughly the same bottom end (exceptions noted in previous posts), so in theory should be able to accommodate either Cruze or Spark mounts as their positions on the block would be the same.

 

What I have found from my own light research is that the MAP sensor across the 1.4 in our cars appears to be able to read boost from the factory.. oil pan is different between cruze + spark... cruze is DI vs SFI on the spark, and the CR's are different. It's very likely that you COULD bolt on the cruze 1.4 turbo + all its associated lines to the spark 1.4, AND HPTuners now supports the spark so you CAN tune the PCM for it. Mostly I'm waiting on my warranty to expire so I can play

My warranty and extended warranty are long since over (103,156 miles on my 2017 as of this morning) , that's why I'm starting to look at this more.

27k to go and I'll be expired and looking as well

Has anyone followed up on this topic? I'm really interested in swapping a Sonic motor into my spark.
