You may be right. Actually, the pump and injectors both had e85 compatible in their descriptions. I have always been skeptical if there is actually a difference but I guess error on the safe side unless you know for sure or are willing to experiment. Again, I'm new so I'm learning as I go.

I'm new to this so additional research is recommended. However, in my mind it comes down to air fuel ratio and the capacity of your pump and injectors. The higher the percent of ethanol you run, the more fuel you need. I believe the stoichiometric afr of regular 87 is 14.7, for e85 I believe it is 9.7 depending on the actual percent of ethanol as it varies depending on the season. That number represents parts of air to one part fuel. If your pump and injectors can be increased and you can hit the afr you need you wouldn't need to change the pump or injectors. However, I'm also adding a turbo s

The pump is back in the tiny tank. Time to hook the tank back up to the car.

Possibly the first and only Walbro450 custom fitted Chevy Spark fuel pump set up. I decided to go minnow bucket style on the lower basket. MN custom touch.

The engine bay is a bit disassembled from the injector upgrade but you can see I kept the blue and black contrast under the hood. I plan to wrap the intake pipes, manifold and Down pipe in black titanium heat wrap.

Happy Friday! My injectors unexpectedly arrived today. I did as much research as I could to try and find a match. Good luck finding something that states it fits a chevy spark besides an exact replacement. I looked for an ev14 which describes the electrical plug and the size of the inlet at the top. I then looked at the length of the body. As for the upgrade, my stock injectors were set at 24lbs/hr these are rated at 80lbs. Stock injector is on the right. The 80lb injectors have been installed.

I ordered a walbro450 for $100. This is a 450 liter per hour fuel pump. Like my injectors it is a bit overkill. However, I now plan on running e85. I dropped the fuel tank and removed the fuel pump basket. I'm working on getting the walbro450 to fit. As you can see, the pump is a bit larger.

I tried decapping my injectors to no avail. I picked up some 80lbs injectors though. Will be going the e85 route. Any idea on an engine? Sloppy mechanics on YouTube and spptv show a lot of potential in junkyard ls motors

Full disclosure, I failed miserably at decapping the injectors. The main issue is the cap is recessed where the injectors in the video I posted have caps welded on the outside of the tip. The good news is my efforts to remove the injectors were not a total waste. For about the same price as stock injectors, $175, I was able to pick up 4 80lb 850cc injectors. This will allow me to run e85 and means more fuel and more octane for potentially more boost. All in all I'm happy with the direction the injectors upgrade went. They are flow matched and more than large enough.

I worked on getting to these fuel injectors a little bit each day. It took a lot of patience and progress was slow but I have the first of 4 injectors. You can see the four pin holes for fuel to spray out. I'm going to carefully grind along that tiny circle weld until the cap pops off and I should have one large hole for fuel. I'm going to do a bit more research before I start to grind

Fire Spark, I will be pressing my luck with stock pistons. I'm planning on running low boost and high octane with e30 or higher ethanol blends.

Slowly connecting the turbo and the exhaust manifold. I had to remove the waste gate and I will have to make a custom bracket for the wastegate. I will include more info on this in my lessons learned but in a scenario like this just go universal turbo andyou will avoid many of my issues. Still loving the project though!

I mentioned this in my hp tuners forum but I received my air fuel ratio gauge. I'm going to practice using the guage to tune my jeep using hp tuners and then move the guage over to the spark when it is ready to start. The obd II port allows you to plug into the car and hp tuners to see real time info on the guage and log data in hp tuners.

How cold are we talking?

The exhaust manifold is finally welded. I ended up making my own pieces to better fit the turbo. I'm hoping to have the turbo mounted in the car before the end of next week. The exhaust manifold and turbo connection still need some fine tuning but it's getting closer

I ordered a wide band guage from AEM. A wideband replaces the second O2 sensor or can just be placed in the exhaust and reads the air fuel ratio. This guage plugs right in to the obdII port and can log data in hptuners. This is crucial for me to adjust for the increase in air with my turbo and increase in fuel with the modified injectors. Here's a video explaining it a bit

Now, you need to remove the intakemanifold with ten bolts, three of the ten bolts are also securing the fuel rail. The fuel rail is under the top of the intake manifold like a surfer in the barrel of a wave. These diagrams are of the back of the engine and don't show all of the tubes and wires that make this slightly more challenging. I have 9 of the 10 bolts off so far.

To access the fuel injectors you need to remove the rear bracket from the intake manifold with three bolts and the two side brackets on the manifold. The side bracket near the throttle body (pictured) has three bolts and the one near the oil cap/dip stick has two bolts.

I will be decapping my injectors and sending the decapped injectors in to be flow tested.I will post the results for anyone interested. My injectors appear to have recessed caps so the process is a little more delicate and slightly less documented.

I came across this youtube channel and specific video on decapping fuel injectors. With my turbo set up, running e30 and having hp tuners, I think this is a great option. I'm going to look into it tonight. Here is the video.

My exhuast manifold is taking shape. I'm going to cut the bolt holes out and weld threads on the flange. The hot side of the turbo has a really weird flange so I'm forced to customize a bit. I still have a bit of cutting and grinding to do as well.

these modern airbag systems do tie in together. If a selt belt sensor is activated or an air bag sensor it can be bad news for the system as a whole for functioning. They replace or reset the piece that is the issue and the system should work again. Think full circuit. So did 3 airbags go off or was it just a sensor issue?

This is a bad picture of the matte black because the picture was taken while the clear coat was drying but I wanted to show off my door jam and interior color scheme. Some call it lazy, others call it art.

The flat black helped clean up under the hood and I like the cleaner more discrete look.
