About this engine

A genuine Mezger from a 997.2 GT3 with 28,500 kilometres, dry-sumped and titanium-rodded, spinning to 8,400 rpm. These are finite: Porsche stopped building them in 2011 and the racing bloodline goes straight back to the 911 GT1.

What you get

  • Genuine 997.2 GT3 Mezger
  • 28,500 km, dry sump, titanium rods
  • 8,400 rpm redline
  • Appreciating collector powertrain

Known fitment

  • Porsche 911 997 GT3
  • Porsche 911 996 GT3 with adaptation
  • Track and race applications

This list is not exhaustive. If your chassis is not here, ask — most swaps come down to mounts and sump clearance.
