I never used the balance shaft belt...what i do is get a H23 tensioner an belt an throw the h22 tensioner away an leave the balance shaft off you will build more oil presure ,more power an easy revs, an relibility on the h23 tensioner....just my 0.02 cents...note it will have some vibrations...but if your using poloy/eneregy suspension mounts then you might not even tell it because your car vibrates already
