Custom 2.5 Liter Engine Rebuild
Power with Flexibility

S14 cams in cambox

Since I first aquired my 1988 M3, I felt that I might one day convert the engine to a 2.5 liter "Evo III style" unit. That day came sooner than I expected when I spun my #3 rod bearing at Laguna Seca in November of 1999.

Below are items of interest from my 2.5 liter S14 rebuild:


• My custom 2.5 L S14 specifications
• DSR Dyno Results
• Cyl. Block Sonic Test (tech articles)
• Pauter connecting rods
- Includes bearing clearance and rod bolt stretch
• BMW Motorsport Gp-A Exhaust Header
• Some seriously abused S14 rod bearings...
• Burnt S14 exhaust valve
• Evo III Intake Trumpets
• Improved ignition coil mount
• Adjustable muffler clamps
• Stiffer transmission mounts
• EVO lower airbox w/ Evo III intake trumpet
• Hoisting the engine in
• Modified intake plenum
• Cyl. head oil restrictor
