F4R874 re built engine

Discussion in 'Car Parts For Sale' started by Chris79, Jun 15, 2026 at 9:01 PM.

  1. Please see description below. I built this engine for my R26 track car with the intention of getting it back out on track after 3 years off the road but realistically, I prefer my c63 amg purely due to comfort. Will be putting my car back to standard to sell, so this is available.
    Engine has not been timed up yet but the guts of it is done. Will be done before sale upon receipt of sale agreement. I have many pictures of the build but please see attached for reference.
    Thanks, Chris
