Concept Z has them at the best price I found. I'm fairly certain the ATI Super Damper you want (OEM replacement and non-dry sump application) is #918584 (https://conceptzperformance.com/ati-...84_p_25524.php) **EDIT** this part is a 4% underdrive pulley and not the same size as the stock crank pulley.

Part #918565 and #918566 are for dry sump applications.
Here is a chart from ATI's website: ATI - Super DampersŪ for Nissan Engines

Or, you can contact MA-Motorsports. They are the ones who worked with ATI to have them built.

Just look into Conceptzperformance and yes they have 2 of them. One seems to be the one I am looking for since the other version says for dry sump only. Good price too. Thanks guys

But there are 2 types of each of those. A stock size and an undersize. I'm finding this out the hard way as it appears I ordered the undersized one by mistake.

I've recently come to find this out when I ordered the one I linked above. It is smaller than my stock pulley and I'm trying to return it. MA Motorsports posted in another thread (think one of their GB threads for it) that the part numbers on the ATI website have not been updated to reflect the stock size wet sump vs dry sump applications. MA has an internal part number for the stock size wet sump application pulley. I don't know if that is something that ATI stocks or MA has to get a group together before a batch is made. I have reached out to MA.

My ATI dampener is a little smaller then my oem dampener. The way I found out was when I installed my belt. The tensioner pulley was in a different location from where I marked it.

Ok so there isn't an ATI stock size wet sump application pulley? Just one pulley for wet sump applications, and it's a 4% underdrive pulley that is approx 3/8" smaller diameter than the stock pulley.

For dry sump applications, they have stock size and 15% underdrive options.

So what belt did you use? Stock size or slightly smaller?

I don't think my ATI is 3/8" smaller then my oem. I used my oem belt. When I bought mine off of the MAM group buy. There was only 2 options. Wet sump or dry sump.

Well, I just measured slightly over 5-5/8" diameter on my new ATI pulley and slightly over 6" on my stock pulley. I've reached out to MA, so we'll see what they have to say

Jon over at MA Motorsports said exactly what we seem to have concluded in this thread: there is no exactly stock size ATI pulley.

The ATI damper for wet sump application is a 4% underdrive pulley. He confirmed that the stock belt size should work. They reused the stock belt for Spooler's build with the ATI damper.
