alright guys, so i believe my alternator is going bad on my jdm b18c and I bought another one from a guy in the classifieds forum. Well I'm not positive what alternator is on the motor since its in storage and I'm not currently looking at it but I know the type r usdm alternators are made by mitsubishi. The one I bought from this guy told me it was out of a type r but its made by denso. Will it work? I believe the pulleys are different sizes? The one I bought is stamped 12V on it, are the voltage ratings for the denso and mitsubishi alternators different?

 

jdm pullies are smaller then the usdm pullies. denso makes some oem items as well.

 

I know denso makes the oem alternators for the non itr motors. But if I use the usdm oem belt, could i get away with a usdm alternator then? I don't see why not? I just need to know the major differences between the denso alternator and the mitsubishi alternator

 

just use the USDM alternator with the USDM belt.

 

alright thanks
