Billet Porsche 993 Turbo Cylinder Head Unboxing, Review, and Factory Comparison: Part 1
.
We recently got shipped some Billet Porsche 993 Turbo Cylinder Heads from Pauter to install flame rings and wanted to do a little review and factory comparison for you guys :) In this first part we'll be covering everything from how these heads are packed for shipping to all the differences you'll expect to see compared to a factory 993 Turbo Cylinder Head including valve size, port size + exhaust port shape, cooling fin thickness + the impact that can have on thermal diffusivity, etc.!
Stay tuned for the next part where we do a deep dive into the metallurgy and discuss which alloys work best for Cylinder Heads and why 🔬🧑‍🔬
