We've just released our own idler pulley kit to replace the air pump on an FD which is necessary to keep proper contact on the water pump pulley. This piece is engineered like the rest of our products: direct fit, aesthetic design, and quality components.

Features:
-CNC'ed 6061 Bracket Anodized Black
-Stainless shoulder bolt and hardware
-OEM quality pulley designed for high RPM
-Belt available for stock pulleys (belts for other variations will be available soon)

We know that there are a lot of variation in turbo placement so we have a pdf available to test for fitment on your setup before purchasing.

Please check our site for more details and purchase: FD3S Idler Pulley Kit

 

Awesome! Hope you've spec'd a high quality bearing that can take the revs

 

This was one of the main design considerations. The pulley and bearing are an OEM piece designed to handle high RPM. Also, the pulley size on ours is larger than most in order to keep the speed of the bearing lower.

 

Good answer

Will be buying one even though I don't need it (yet)

 

Purchased. Should go nicely with your rails and trigger assembly.

 

Any chance of doing a group buy on these?
