ok Im gonna try to keep this somewhat short. i have 2 motors apart. building one. my b20 (not building) had a crank timing gear and an unorthodox racing 1 belt pulley. my b18 had the stock harmonic balancer. now im building the b18 and have it somewhat together and wondering which pulley set up to use. I understand the unorthodox pulley is way lighter which is good, but I understand that you gotta keep everything with the harmonic balancer. main question is it bad to use the lighter racing pulley over the stock harmonic balancer?

Back in the day when I was up to date on everything it would be a solid no to aftermarket pulleys. Now though I am of the opinion the rubber insert is more about the shock of the compressor engaging, so, IMO, if you don't have A/C I think it doesn't make any difference.

You will no doubt hear otherwise though. Personally, I am running stock with the p/s ribs cut off and then turned smooth on a lathe.

yea im not really sure. eventually i want to sleeve the b20. I just don't want something like that to jack up my motor. anyone else have opinion on it? also what are the 2 sensors on the passenger side of the head (under the vtech solenoid). for some reason I cant find mine and cant really look them up if i dont know what they are
