Hi, need some help, have an automatic 1999 mazda miata w/ a 2004 mazdaspeed turbo kit on it, but last friday my radiator blew up, not over heated, just the plastic blew off, wanted to replace it with an aluminum aftermarket, koyo, haste, or any one, but they are for manual trasmisions, automatic cars had the transmision oil cooler on the radiator, does some one know any aluminum radiator to fit on my car ? or any ideas ?
thanks !
