I hydrolocked my B7 with an AEM CAI. Put 2 holes in the block. h:

A fine mist of water is called water injection. It was used a LOT by the GN guys until they went to the alcohol injection. A lot of RX-7 and DSM guys still use water injection.

Anyhow, we'd really need to know more about the car before recommending a swap.

 

Water messed up my Ls and faged up a rod. So I took the car and did a crazy ass burnout they the rod hit my radiator, and they went though the hood. Nice Had to replace 3 things. Sucks
