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
