it wont last long stock. thats why i was suggesting built internals. mustang engine may last past 300k miles with the posi charger or it may last a cupple weeks after you put it on.

My question about the air to water was is there another place to put it besides front mount. i haven't seen one put anywhere else thats why i stated a front mount air to water.
if you have a air to water and you want more hp, do you think CO2 spray or NOS would help the intercooler cool the air down or is that technique strictly for air to air
ryan that engine looks amazing. did you take the engine completely apart and sand everything down and then paint the outside or did you just paint it when it was together. plus how did you strip the clear coat and the ugly gray coat off the m90 or did you just paint on top of the coat.
