I'm Automotive Engineering student from Finland, and I'm developing four-cylinder BMW M10 2.0 '77 turbo engine as my engineering/diploma 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.

Engine specs and construction:
- Bore 90.0mm, stroke 80.0mm
- Valves 46mm intake, 38mm exhaust
- Cylinderhead BMW E12 2.0 '78
- Crank BMW Original forged steel, nitrided
- Camshaft Dr.Schrick 304 (Adv. duration 304 deg. lobe angle 108 deg. lift 10.7mm)
- 4x45mm Individual Throttle Bodies
- Suitable big turbocharger, Garrett GT3582R dual ball bearing unit looks very neat
- Intercooler core size 600x300x75mm
Engine management, sensors etc:
- GenBoard/VerThree V3.2, loaded with ~all I/O options
- 8 injectors (four small in ITBs, 4 big (~900cc) in the end of velocity stacks)?, GenBoard/Manual/PowerFlyback
- all 8 injectors connected to separate injector output channels, so sequence can be reconfigured from software ? (or some shared?)
- I was thinking to connect each of them to individual outputs. Not sure yet about the configuration. Full sequential adds complexity(CamTrigger), but would make life easier for GenBoard. My intention is that the first four, small ones, operate at low MAP/load/cruise, and big ones operate at under boost/WOT.
