Hi, I've been searching and have came across way to many different answers so I'm resorting to posting this to try and figure it out.

I have a 2002 LS1 out of an F-Body that I'm swapping into my 350Z so my knowledge on this engine isn't all that just yet.

I want to purchase the ATI super damper for my motor (the one without the A/C pulley) but was curious on what belt I need for it because people seem to be always running into the issue of getting the wrong belt.
Any thing I need to know for the install? I know to silicone the little groove to keep it from leaking but aside from that, what am I missing that I might need to do?

Thank you in advance!

I'm running a stock length belt on my ATI pulley, are you getting a stock size of under drive version ? Are you talking about silicone for the key way?

What year 350Z is this LS going in?

If the diameter is the same then it uses the stock belt.
If it's a new build and you need to start from scratch.....
Belt width should be the same as stock... If you're not sure about the length needed I have always used a piece of string or thin rope. Did a quick search and found a site that does a pretty good job of explaining it. How to Determine Serpentine Belt Size

Cool, I will look into that thank you!

Cool good to know! Yes, I watched a couple YouTube install videos and they all seem to silicone the little key way slot so it doesn't leak oil. It's a 2003 350z.

I didn't silicone mine, doesn't leak a drop. Make sure you follow their installation procedure, which includes measuring the crank and the ATI hub to 1/10,000 inch. They have an interference fit requirement for installation. The ATI pin kit is something else to consider. Use the correct installation method, i.e., not LS1howto.com!!!

Nice, I had a 88 300z in high school traded it in on my Camaro, still wish I would have kept it for a LS swap. Good luck with project.
