What has to be done to the motor to be able to run water meth injection? Do you have to have forged internals? Headstuds?

 

Nothing special has to be done besides taping the uicp to install jets or nozzles.

 

so it wont damage anything?

 

No damage will occur if installed correctly and a properly designed system. Is the the low cast systems with check vales or homemade systems the can lead to problems. May people use water methanol as additional safety factor for poor quality fuel, additional intake air charge cooling and reduce carbon build up.
