I'm gonna do my TB soon, and I am gonna order the kit from ecstuning.com, Should I spend the extra money and get the kit with the light weight crank pulley? What kind of benefit will I get from this, anyone else running this?

 

Not a huge gain, just a slightly faster revving engine

 

So there would would it make less stress on things?

 

well, it will a little bit, but the stock one is just fine. you can replace it with the new light weight pulley if you want, but as stated on here in previous threads, there are better mods to be saving for with that money.

 

The crank pulley is also known as the harmonic balancer which is weighted a certain weight to keep the engine in balance. Changing that weight can slightly throw the engine off balance and reduce engine life.

 

Ok, Well then I'll be keeping the stock one.
