M20 Race Stroker Engine

Our "Stage 3" engine. The BimmerHeads "Race" M20 Stroker long block engine is for the those who are truly power hungry! This version of our M20 engine is great for those planning to build a high horsepower stroker or a turbocharged monster. Take things to the next level by adding our +1mm oversized Supertech valves or turbo upgrade to your Race engine build. Turbo upgrade includes heavy duty pistons and wrist pins along with an upgrade to the Power-Adder version of our Molnar H-Beam connecting rods. The standard compression ratio included for naturally aspirated engines is 10:1. The standard compression ratio included for turbocharged engines is 9:1.

All BimmerHeads M20 engines undergo in-house testing on our custom built engine run stand in order to break in the camshaft and engine components, check for engine oil leaks, and of course for quality control. We NEVER slap something together just to send it out the door.
