Ill be calling AEM tuesday but does anyone know why they have 3 different part numbers one for the vtec, non vtec ls, gs, rs and lastly for Type R... are the belts different? pulley size different?

thanks

 

Crank pulley is different on all of them. PS is the same on all of them, not sure about the alternator and the AC is smaller on the GSR then the LS (as I recall the LS AC pulley is larger then the Alternator and the GSR is smaller then the alt). The type R is smaller then the GSRs (as I checked the other day w/ my swap). Obviously slightly different belts are involved for each.

 

thanks just the info i was looking for
