Research the crank pulley change. You'll find that it shortens your engine life due to increase wear on the bearings.

Regardless of what you do. The crank must me rebalanced. Otherwise your nolonger driving 100,000+ engine. Do what you want just don't complain when you start having engine problems.....

i believe the cranks are internally balanced shouldnt have a prob with it other than the possibility of less oil but thats easily fixed with a high volume oil pump but i wouldnt worry much UR makes excellent pullys so crank away Rafavtec
