New pistons, crankshaft, rods, balanced and blue printed engine. Thermo coatings(everywhere). New beefier radiator(2cm thicker than stock) new larger oil cooler and FMIC. PPK HD radiator fan and aux water radiator. Different turbo and DME sw to run on 98 to 102 octane pump fuel(available at most GErman gas stations). And the engine's oil system was totally reworked to work for the high G-forces w/using slicks or semi slicks. The oil pan was a custom piece bc they couldn't use the S55's oil pan bc the front sway bar interferes on the M235i compared to the F8x cars.
