5sfe performance mods Options

I have a piggy back ECU installed that makes my Celica "flexfuel". It runs way better on E85 than pump gas.

This mod is great because it increases performance and saves me a bunch of money on fuel. E85 ethanol pumps are going up everywhere, and if you have one near you, I would consider this upgrade a necessity.

E85 is 105 octane. Thats why it will increase performance, even on a 5sfe with no mods. The owners manual "recommends" 91 octane so you know that higher octane is going to increase performance. The easiest way to increase performance is to increase fuel quality, and this mod will save you money at the same time.

Believe what you want about the rubber components. If you want to continue to believe the oil companies that you they sell a better product, thats your decision. I was just trying to save some people from having to buy $5 gasoline. The corrosion myth is completely false though.

"Ethanol has a lower ignition temperature so the engine overall will run cooler increasing power. It also burns slower so instead of just burning out in one violent explosion forcing the piston down, it continues to burn the entire length of the piston stroke expanding gases more evenly and smoothly. So running E85 will give any engine more power over any pump gas. Also E85 is 105 octane. Gas comes in 85, 89 and 91 octane. The 105 octane of E85 will help to eliminate knocks and pings. All of these benefits will make an engine run smoother and quieter."

Also, I am obviously aware that the 5SFE motor does not have a lot of potential for increasing power or efficiency, especially because it has no VVT. If one were to try to maximize power, you could change the timing to 0 degrees and increase the compression ratio to 12:1.

12:1 huh? Hehehe... because it's THAT easy.
