DIY: Stanceparts Air Cup Kit (91-05)

[Chris_Lum]

This video is a long detailed video meant to walk you through a step by step installation of the Stanceparts cup kit on a 91-05 Acura/Honda NSX. This is using Stanceparts cups with a 1.5Gal Viair tank/compressor combo. Modifications I've added to the factory setup are: Electronic Purge Valve and switched compressor and purge valve. This is for a 2 cup setup and front mounted tank, however it will work the same with the tank mounted in the trunk, you will just have to use longer wires and possibly thicker gauge wires due to the added length.

Parts Used in this video:
-Stanceparts cups (Sized for KW V3 Shaft)
-Viair 1.5Gal Tank/Compressor Combo

I wanted to say thank you for the post and info. Well put and after seeing this and your other thread, it deserves a shoutout. Even if it’s not for everyone, content like this definitely helps the community. I dig it and can see use for this in the future as my build comes along. Thanks again for sharing.

Thank you for your positive feedback. A cup kit if one of those setups that can be done in many different ways and this is my way of doing it, but I'm happy at the end of the day if people can even just use it as inspiration for their setup or as help to point them in the right direction or to even just let them know what all goes into it. I had a lot of help from friends and local NSX owners in putting this together and just want to help others in some way as well.
