Ive already searched this, but no solid answers. Most only talk about b16 vs type r or gsr.

Im gonna be doing an ls/vtec setup again here shortly and would like to know which timing belt gear to use. I have the gear already on the ls block right now, but im not sure if its the same as all the others. I also have my b16 motor with all the parts on it. So basically, im gonna use either of the two. So are they identical, and if not, which would i use?

 

i think they are diff. one has more teeth than the other

 

Yes they are all the same.

LS/GSR/ITR = 14211-PR3-003

 

Are the b16's the same as well? sorry this is OT, but can you use the b16 crank pulley for the LS? The only difference Ive seen was the weight.

 

cam gears are the same, crank pulley not the same but will interchange

 

Being that im gonna be using my B16 crank pull on an LS block, i should just be able to use alt, ps, ac belts for a 99-00 Si right? or would i need to buy gsr belts. i dont think it really matters to tell you the truth. Correct me if im wrong, but i think all will work.

 

other than the fact that they al share the same part number if you go to skunk2 or aem or something and get adj cam gears (which i would recommend) that also have one cam gear for all b series dohc motors except i thinkl the b20 in 90ish preludes 2.0 si
