Here is my water/methanol injector kit.

First of all, I call it injector kit, not injection system. I hate people calling everything "system", thinking it will make it fancier.....

The 4runner is now at 25,6000 miles.
I removed the cruiser control unit and use it's mounting bracket.
Cruiser control may be your best friend, then in that case you may find other place to mount the pump...

I ran URD 7th kit trough this way also, very easy and lots of space.
Just remember put some RTV or something alike after.
and having fun wiring..

How did it all work out? Did you pick up much performance from the kit????

This post is pretty old, so not sure if the OP will get back to you.

I also run a very similar injection kit. It's only beneficial for boosted engines with high PSI. The power is gained from lower intake temperatures and suppressed detonation, which allows the engine to advance timing safely for more power. I have the 2.1" pulley on my supercharger which tops out at 11 PSI, so the water/meth allows me to redline my 4Runner safely. Water/meth doesn't "add power" in the same way putting on a set of headers or a supercharger will, it just allows the engine to reach its maximum potential after tuning it.

An aftermarket tuning system like an Aquamist or AEM FI/C is recommended to make sure you're not running too rich. Water/meth can cause combustion quench, which I'm still tuning out right now where the engine bucks due to being too rich. I have one more spot to work on.

OK cool, thanks for the reply. How are you tuning it? Laptop?

Yeah laptop via the AEM FI/C 6. Check my build thread if you want to know how I have it tuned.
