I will be turbocharging my M103 (with jayrash help and help and help) this summer hopefuly so... dont scare me guys !
I stand by a fact that mercedes may have overengineered this engine and we all know that. But it wasnt overengineered to be turbocharged and handle 400 hp.
I dont know what is the limt that the M103 can handle but for sure more the setup is clean and well done, less the engine will suffer
The thing isnt by growing the hp and torque numbers...we need the car to run so we can have fun.
Great job on the car man! i really like your exhaust manifold! ive been trying to find one like this since 1 year
