I'm Automotive Engineering student from Finland, and I'm developing four-cylinder BMW M10 2.0 '77 turbo engine as my engineering work.
Major principles in engine development are very good engine breathing and a sophisticated electronic engine management, and my goal is to get around 500hp from it.
Some information about engine construction:
- Bore 90.0mm, stroke 80.0mm
- Valves 46mm intake, 38mm exhaust
- Head BMW E12 2.0 '78
- Crank BMW Original forged steel, nitrided
- Camshaft Dr.Schrick 304
- 4x45mm Individual Throttle Bodies
- Turbo most likely Garrett GT3582R dual ball bearing
- Intercooler core size 600x300x75mm
Engine management, sensors etc:
- GenBoard/VerThree V3.2
- 8 injectors (four small in ITBs, 4 big (~900cc) in the end of velocity stacks), PowerFlyback
- WastedSpark ignition, Bosch 0 221 503 407
- Motorola MPXH6400 MAP-sensor (external, on firewall)
- WideBand O2
- BoostControl
