Round 2 - Adjustable cam sprockets for B202, B212 - $300 USD
Posted: Tue May 24, 2016 3:03 pm
Hi everyone,
Price is $300 USD shipped within the 48, or $285 USD + actual shipping for the crowd who lives outside the US. No payment is required until the parts are ready to ship. I expect to have parts ready in 3-4 weeks, so the end of June.
Based on the interest in Luke's thread for another round of adjustable cam sprockets I'm making another batch.
These will fit B202, B212, and early '90-'93 B234. These allow you to time custom cams, mess with overlap, and to compensate for a cylinder head that has been cut thin enough to throw off the factory cam timing.
At this time I am planning to make 12 sets.
They will be identical to the original batch, and will include the modification I had to make later to make sure the chain links do not touch the aluminum hubs.
The indexed adjustment goes from -10 to +10 camshaft degrees from nominal. (For reference, one tooth on the sprocket is ~9.5 camshaft degrees).
These are made from 6061-T6 aluminum for the hubs, steel sprockets with hardened tooth faces, grade 10.9 metric fasteners, and a hardened steel dowel pin that clocks the hub to the notch in the end of the cam.
I have had a set of these in my car for ~10k miles now with no issues.
What you get:
-A pair of complete sprockets, with fasteners
-An aligning pin to lock in your desired timing during adjustment
-A few extra fasteners
-An extra dowel pin
-My gratitude
The list so far is (11/12):
-Luke
-Tsmall
-Jon1 (2 sets)
-gmreider
-Neil_G
-Crazyswede
-iceman_ca
-vintagesaabs
-tirediron
-Nate
Please let me know if you'd like me to add you to the list.
