Not the first time that someone put Saab’s engine in BMW. We already had an example of installing Saab’s B206 engine in BMW M3, and here’s a new example of swapping SAAB B234 engine in BMW M3.
Project called AERO M3 Turbo was conducted by 011 Racing Team of tuners from Belgrade, Serbia. The car was started as a salvage project for a nearly destroyed engineless M3 chassis.
The idea was to use a SAAB engine, which is a very reliable choice and able to cope with bad fuel quality they have in Serbia, and to build a car that will be used on occasion, for track, etc.. In the meantime team leader Aleksandar decided to built an all-round car with no corner left untouched, so this project was started, and took 2 years to finish.
The result is the car shown here. Car was built by members of 011 Racing Team in Belgrade, Serbia, with lots of ideas, help, input and advices from Presho, guys at Maptun, Cannonball Forum, and lots of other people. Concept was created by Presho a.k.a. BOOST, built by 011 Racing Team: SAAB B234 2.3l, Trionic T5 engine management featuring automatic ion knock and boost control, individual Stage X tune by Fredrik from Maptun Performance. he decided to combine 3 different types: block and crank are from SAAB 9000 B234i (used, with some 150K miles on them), atmo version of the engine, Conrods and pistons are from SAAB 9000 B234R 2.3l Aero version, and Head is from a B235R Saab 9-5 Aero.
E36 M3 6-speed gearbox coupled to SAAB engine block and added a turbo Garrett GT35xxR hybrid @ 1.9bar, and furthermore: RC Engineering 1000cc injectors, Intercooler with CO2 spray, fuel CO2 cooler, Mocal water/oil heat exchanger, TIAL 44mm wastegate, Turbosmart 38mm Blow-off valve, Turbosmart adjustable fuel pressure regulator, 2xBosch Motorsport fuel pumps, ATL Fuel Cell, Wizard of Nos direct port nitrous system with progressive controller…
Rototest Results and Performance
Final results measured by Rototest: Wheel power – 472PS / 573Nm; Engine power ~550PS / 670Nm on 93 octane fuel. Power with 102 octane fuel: 650PS / 750Nm!
- 0-100 km/h: ~4.5s
- 100-200 km/h: 7s
- Max speed: over 320 km/h
Easy to tune to high power levels with minimal hardware upgrades, which are at least 3x cheaper then upgrading BMW engine to cope with same power, then ability to put out high power even with very bad fuel in Serbia…
