Turbo Project

The wire and plug that hooks into the flex fuel sensor were delivered today. It is a perfect match. I was under the impression that it had the metal ends that fit in the J3 plug of my wire harness but it does not. Luckily, that sonic forum provides that information so I will order the rest of the parts/tools that I will need. Unfortunately, I had to order 25 so if you need some, let me know! Only cost $14. Total cost is still pretty low.

Nice build. What kind of power numbers are you hoping for?

I have been thinking about this a lot lately. Still no clue where it will end up.

I bought black exhaust wrap to keep temperatures under the hood low. The first piece I tried was the down pipe. I also used a black sealer spray paint. Not bad for a Chevy Spark.

I hooked the flex fuel sensor into the fuel line. I still need to put on hose clamps and wire the sensor. It's located just before the fuel rail.

I finished wiring the sensor to the computer and enabled the flex fuel sensor in the computer via hp tuners. I will still have to tune the vehicle but there is a baseline that will change based on ethanol content. I ordered a badge for the hatch.

 

The ZZP midpipe I have been waiting for is finally back in stock so I ordered that as well. Should be here by early January.

I finally was able to get the exhaust manifold to bolt on to the turbo. My uncle helped weld on the bolt threads and I'm really happy with how it worked out. I still have to move the radiator and hose a bit but I was able to fit the turbo in with the downpipe on for a test fit. The downpipe looks like it will work perfect with the midpipe I ordered and the rest of the exhaust. I will be wrapping the exhaust manifold for heat reduction and start working on the oil lines next.

I heat wrapped the exhaust manifold. I'm still new to exhaust wraps but I think it looks better than the stock heatshield(not that it would fit) and is probably more effective. I plan on getting a turbo blanket as well in the near future.

I was planning on moving the radiator more which I may still do but I'm thinking I will buy a reasonably priced radiator fan that is slimmer than the stock fan. I'm not worried about temps as much as gaining space.

Thanks to someone on this forum, I got a 3 day subscription for GM service manuals from AC Delco. I looked at both the Spark and the Cruze (both have the e78 ecu). Also, the turbo I am using is from a 2016 Cruze and has the plugs and wires.

 

I believe I am now ready to wire the bypass valve and solenoid. The green wire on the turbo bypass valve goes to pin 32 on the J2 plug on the back of the ecu. The brown and yellow wire on the bypass solenoid goes to pin 63 on plug

J2. The other two wires should go to a power source.

 

Once wired and enabled, the bypass valve and solenoid should be controlled by the stock ecu based on the settings I set using HP tuners.

 

It appears all relevant  tables for the turbo are accessible in the spark ecu through hp tuners. It is just a matter of enabling them.

My zzp midpipe arrived, my oilfeed and fittings arrived, my oil return and fitting for the oil pan arrived, my radiator fan also arrived. 

 

I started test fitting my midpipe exhaust and it looks great. I will have to cut a bit to fit and maybe even weld but all of the parts are here and it is easily remedied. I also finally have a welder so I have more flexibility. 

 

I installed my aftermarket radiator fan for more space and tested it using HP tuners. Here is a video showing how powerful the fan is on each setting and how much HP tuners can do.

I had to shorten the ZZP mid pipe that I bought which was designed for the chevy cruze 1.4 turbo. I picked up a two bolt flange, cut the pipe to fit and welded on the new flange. I used a cheap wire feed welder with flux core wire. This is actually my first real weld since high school. I did a few test lines for wire speed beforehand. It's definitely not pretty but it works and the pipe fits great. I just have to get bolts, gaskets and work on finishing hangers and the exhaust is done.

Beyond excited to see the end result. I came across this while wondering how to tune my 2013's ECU. I have always thought about trying my hand at a turbo now that I'm past warranty... and after driving my new (to me)mini cooper s, the spark takes patience to drive. I am curious since the 13-15 sparks are just about the exact cars, would they all be e78 ECUs? Its hard to find definitive evidence of that. I have been very interested in some more modest upgrades lately.

 

Good luck! Keep us posted!

Thanks! I believe they have the same ECU but I will triple check. The computer is used by a wide range of chevy models and years. Hp tuners also has a vehicle list to check what they cover. I'll let you know here shortly.

 

Edit: after looking it looks like yours may have an e83. It looks like 14 was the first year of the e78 for the spark. I'll look into this more and see what your options are.

 

I've seen some comments on the hp tuners bulletin board mentioning e83. I posted a thread asking about 2013 spark compatibility. I'll let you know if I hear back.
