lightweight crank pully
This may be somewhere else in the forums, but i couldnt find it anywhere.... so.... the question is, would installing a light weight crank pully do any good for a stock tc with header and exhaust upgrades or would it just be a waste of money in terms of improvement?
One more thing, its not about a crank pully but the grounding kit, could someone tell me a little bit more about it and its benifits?
I would appreciate this greatly

with a good search you can find the answers to your question.
as far as the crank pulley goes, there are people that say it is ok, and people that say it isnt. I am from the school of thought that it is bad for the motor. Mainly because I had a crank bearing problem without even having one of these pulleys. It puts more stress on the crank and has a harmonic resonance that will cause problems. I would not recommend the lightweight crank pulley to anyone.
I say its not worth it to risk your motor, but your choice, and this is just my opinion.
As for the grounding kits, ive not done a lot of research, but some people swear by them and others swear AT them

My friend has a 2006 subaru 2.5i and the motor started knocking and then just went up in smoke. He found out that it had something to do with the agency crank pulley he installed. So if u are unsure about how safe it is, it is better not to do it.

You do not want compromise the longevity of your engine. While we have an internal balancer, the torsional damper eliminates the resonance. With out it you are subject to potential damage to the bottom end. To each is own, and a lot of people swear by pulleys, but I would not compromise my engine. Just add a light weight flywheel and you will feel almost the same gains with out compromising anything.

I would greatly appreciate it if you told me the vital steps please. Not trying to sound smart i would like to know. I read the dIY on the lightweight ZPi pulley which is the same thing because of the Oem sizing.

ITs very easy there is a tensior bolt inbetween all the pulleys you put a 19mm socket on it and pull forward this realease the tension on the belt and you swap out the pulleys then realese the bolt to put tension back on the pulley's, two man job one pulling the bolt one putting the pulley on, def. use a airgun to put the pulley bolt back in and thats all there is to it

keep your stock pulley. dont waste your money on a a/m light weight crank pulley... it will catch up to you in the long run.
as far as a grounding kit, it wont help you for anything. are you running a massive system? if so i would hope you, or whoever installed in knew how to ground it right

So 2azfeboost?now im starting to think you are just trying to sound smart becuz u still didnt tell me how i did it wrong. Yes I had a friend to pull the tensioner bolt. Thanks Svicks. It was very easy and i think i am probably the only one on this forum that did it with only wrenches. When i screwed it back in , i added a touch of loctite blue. and there you go. I rechecked and thePulley is still on and does not move side to side. So please tell me how i Totally messed up.
