ok, some background... im working on designing out a twin turbo system for my clk55. i would like to have the intake pipe come straight up from the intercooler and into the intake manifold, however the throttle body is currently facing the rear of the car.

does anyone know if the intake manifold can be just turned around? i know this would affect some vacuum lines attached but those will be rerouted due to the turbo anyhow. looking at some pictures i think it is capable of just being turned around. i guess if no one knows for sure then the best way would be to just unbolt it and see if it will bolt up in the opposite direction.

is there any other issues other than just fitting the intake manifold in the opposite direction? will this affect engine operation? from everything i know about the engine, i think it will be ok. obviously the injectors will have to stay in their same cylinders, and as far as i know the flappers in the intake all operate at the same time.

now that i think about it, i think the egr line will need to be re routed but i will be using custom exhaust manifolds anyhow. anyways, some advice and brainpower are definitely welcome Click here to enlarge
