a gsr motor and head, does it have the same size timing belt as an lsvtec?

 

match the timing belt to the water pump, and NO b16 timing belt

 

it matches. wouldnt they all?

 

u wouldnt want to use a ls timing belt with a vtec water pump, they have a different number of teeth. So go with a gsr/typeR timing belt if u have a the vtec water pump or use a LS timing belt if u have a ls water pump. Going with the vtec ones is the more popular and safer bet

 

GSR belt for GSR/B16/type-R water pump.
LS timing belt for LS water pump.
