Hi everyone, I've recently purchased a 1999 legacy gtb rev A, ej208, and am thinking of building a water/methanol kit for it. From what I've read the w/m injection can help keep your cylinders and pistons clean and also cools everything down A LOT. With this temperature reduction, apparently there's a gain of horse power as well. They also are supposed to prevent pre- detonation/knocking, while running on poop gas. The spray nozzle would be put into the throttle body elbow. Does anyone here have any knowledge of w/a injection on a stock EJ208 and the effects it has? Are these kits still useful on our lovely boxer engines? Hopefully (if others think its a good idea) I can install it and then others can install one because of this thread!
