Came upon a good deal on an old, discontinued, but unopened Edelbrock water/meth injection system called vara-jection. Seems it can spray based on RPM and Pressure, but I can't find much more about it except that the muscle cars used to use it, and it was discontinued because a bunch of motor home guys were putting it on, setting it to full spray all the time, rusting out hteir engines, and then suing edelbrock.

Anyone know anything more than me?

according to this it was designed for a districutor system, if I can't end up making it work on my planned turbo '92 miata I'll put it on my 92 turbo mr2, which has a dizzy

 

If I remember right the pumps that came with those barely put out more pressure than a windshield squirter pump. Post up some pics so we can take a look. There has to be something salvagable.

 

now that just makes me cry. well, I can always use it on my mr2t. I plan to pump that car's boost to 14psi, which is supposed to be safe on stock everything, a tad bit of water spray would help things stay safe at worst. I'll go devilsown for the miata build.
