sr20det battery alternator
 

does anyone know if i can use the ka24 on the sr20 or where could i find one??

u can use a ka24de, jus have to drill out the hole and swap pulleys

there is a part number on the back of the alternator. you can call up advanced or napa and they can look it up and get you a new one or a refurb if you are lookin to go that route. thats what i did
