Albin Georgssons BMW E21 323
The stock engine is a inline 6 cyl engine called M20B23, manufactured in 1979. It used distributor controlled vacuum/advance ignition and K-jetronic fuel injection. On this car, all the K-jetronic junk was burnt at the stakes and a Motronic intake, fuel rail, fuel injectors and trigger wheel+sensor was mounted.
- Trigger : Stock 60-2 wheel with sensor and wiring from 1988 Motronic BMW 520 (M20B20)
- Coolant temp sensor from Motronic engine
- Intake air temp sensor from web shop (MAT sensor, 14x1.5 mm thread, open air design)
- TPS from Farnell (small form factor, had to use adapter plate)
Interesting fact is that we started up the engine with basically the same config as MembersPage/MattiasSandgren/StefansBMWTurbo and the ignition timing was only off by a couple of degrees initially. Only req_fuel changes were made and it ran close to perfect with a little less vacuum due to what must be a slightly hotter cam than stock.
