OEM Crank Pulley
 

Im looking for an oem crank pulley thats in good condition, I purchased my 370z used and it already had a Stillen under drive pulley installed. So if anyone has one just laying around send me a pm with some pictures and maybe we can work something out!

I have a stock pulley somewhere laying I will find if you want it

I'm not an expert in these matters by any means, but don't people typically install an overdrive alternator pulley when installing an underdrive crank pulley? You might want to check that out if you are switching back to OEM.

NST pulleys come with 10% underdrive crank and 10% overdrive alternator pulley. It's done to maintain stock voltage.

Is NST the only one to do this? Do people commonly run an underdrive crank with OEM alternator pulley?

Sorry for the derail, OP. Last one I promise :tiphat:

Yeah ill definitely take it off you if you can find it, shoot me some pictures so I can see the condition and a price via private message!

Yeah I'm not either but by looking in the engine bay the only aftermarket pulley the previous owner installed seems to be the Stillen underdrive crank pulley, plus stillen doesnt make any overdrive pulleys that I'm aware of.

Sure I'll send you your the pic tonight gave me you email address. I'm sure I have it somewhere in my garage
