I've seen countless forums on this topic but none of them seem to be straight forward and are filled with a bunch of controversy. My question is for my b18c1 block, b16 head with type R crank, would it be best to have a GSR, ITR, or CTR pulley? i dont have ac or power steering so i would need to get that machined off and balanced. My reason for needing a new one is im fully rebuilding my engine and my pulley has a chip on it. Im hearing the after market light weight ones are no good, the CTR doesnt have a balancer so its not good, GSR and ITR are different so it depends on the situation. Im going to be boosting this engine and i want everything to be balanced as much as possible. Im not sure if i have a CTR or ITR crank or if theres a difference honestly. so my final question is for boosting my motor (trying to push 20lbs give or take and make 400hp also give or take) which pulley would be best and why? and what belt would i have to run

 

With all the parts and mods you are doing, I would actually go with the ATI super damper. It will give you all the things you want and added protection.

I agree with TomCat39. Get an ATI or Fluidyne crank pulley and be done with it. If harmonic vibrations are a concern for you, these two choices are far better than any of the OE parts that you have listed above.

 

You can go with ATI super damper and with this, you will get the things you wish along with added protection.
