in the process of putting a 200 tdi ( out of a disco ) in to a stage 1 , I got it in all the mounts for the engine and box are fitted just starting to connect all the pipe work and wiring, but I am a bit stuck on the turbo and need a bit of info , looking at the turbo there is the obvious exhaust pipe to the back of the engine one in line pointing to the front and one pointing to the ground and im not sure which goes to the inter cooler and which one goes to the air filter , also what would the pipes be made out of ?as I think I will have to try to find something to fit
thanks in advance
