I'm looking into this for my BRZ. Alaska's highest octane is 90, but minimum required is 91.
I'm told to look into the Honda high compression motors to see what people have used there. I messaged Snow Performance to get a better idea of what to do. Water/meth has been around since 1920's, so I'm not too concerned with what can happen to the engine. I just don't like pumping 90 octane in it all the time. |

Talking to aquamist about getting a kit. Several hundred bucks, just a couple hundred to install and tune. Not bad.

You'll make more power with nitrous, but meth is a lot easier to come by...
Plus way cheaper I'm personally thinking of throwing a meth kit on the car. Keep in mind you'll need a tune to take advantage of using meth |

I want to know if somebody has tested a meth kit on our cars yet. Being as we have a very high compression ratio, I think we might benefit from meth injection to keep detonation down.

I have the wires to the ecu down so its not rocket science as far as which wires to tap, using positap its clean too, no need for extension harnesses, and a plug n play location for tank etc in our car if you use the same tank as me. the venting of the tank i did a custom job on but its not hard. You do drill holes to mount the pump but its easy drilling. If you run a vortech, they recently supplied me with a dimpled cast pipe that's plenty thick to tap for a jet. I been busy on test an install stuff, I need to tune next and last for power.
Now, I can't comment at all on its value in a NA application, but as its new to me, it comes pretty well recommended from more than a few of the tuners I trust for FI. |

I think for a high compression NA application like our 4ugse, a small port injection system using a sophisticated monitoring and injection system would make water/meth injection beneficial. It's like "helper octane" when you need it; and cleaner too! But most importantly, it's the cleaning action that injection creates that makes me a fan of water/meth injection systems. I have one installed on my MR2 turbo and my butt-dyno agrees with the horsepower increase. It's also great to know that my internals are getting steam cleaned. Injection is a must to have installed on any forced induction system. But the reason why I ask about a water/meth injection kit is that the only clean gas around my parts is 91 v-power. The fa20 requires 93 to run optimally. I hate choking the motor with 91 so I am looking for an alternative way to increase octane points effectively and easily.

Reviving an old thread. Has anyone actually hooked up a meth injection or meth/water injection system on an FA20 yet?
Beginning the research phase now in contemplation of adding this in conjunction with a Phantom ESC versus simply running E85. |
