Modern ones are 500ish $

Designed for boost but they have a controller so they should be able to work without it. Call tech. This one is for a carb or throttle body.

Or old school. 90$ on E Bay. I ran one back in the 80s for a bit.

Might get you by and better than a quench lilling .080 head gasket.

I used water injection on another car a number of years ago. Edelbrock actually had a system at that time. Worked really well with 50% distilled water and 50% methanol. I just seemed to run out at the most inconvenient times. If you used tap water the spray nozzel would end up getting hard water deposits and clog.
