i bought one for my motor but some people say you have to get it balanced and this and that...i just wanna know if anyone has one and they liked it or what your thoughts are on it...again its a JDM CTR cracnkshaft pulley that comes pre-balanced...help a brotha out

 

I'm guessing you mean the CTR N1 pulley?
It is an OEM part and it balanced as closely as OEM parts can get to perfect.
I have not had a problem with mine.

 

its been covered many many times, do a search. but anyway the theory is that it will cause more wear on your main bearings because it does not have the rubber damper inside the pulley. some swear by it, and some people blow their oil pumps after 10K miles. I bought one awhile ago, but after some reading decided it was not worth the risk for a slightly quicker rev and a HP or two.
