The long pole in the tent that I’ve been waiting on to get started reinstalling my motor has been getting my Autospeed downpipes ceramic coated by Swaintech.

While they were being sent out for the coating I decided to send along the turbo inlet pipes that run along the length of the exhaust manifold to give them the coating as well.

I decided to go with the Swaintech coating based upon the advertised thickness which was a good amount thicker than the other coatings that I could find information about.
Another turbocharger option is now residing in my basement. I came across a classified ad for a number of 2.7T parts that included this pair of low mileage BorgWarner RS4 K04’s. With only a little over 10,000 miles on them I could not pass up the opportunity to put some K04’s back onto my S4, or alternatively to use them as the starting point for an upgrade to a RS6 based hybrid.
For the time being I am sticking with BorgWarner K03’s to gather some additional performance data and to try and continue the Nefmoto Stage 1 Tuning thread , but my hope is to swap in the K04’s by summertime and get some numbers on them with my existing additional hardware.
