ENGINE SWAP! A4 TDI engine, VTN turbo ?\'s
i am swapping an A4 TDI (ALH) engine into a VW Vanagon to replace its wasserboxer lump.
it is a NEW engine, never used, and it has a MECHANICAL injection pump installed in place of the standard electronic pump
i need to figure out how to make this thing run, and work.
i dont have the origional ECU, nor do i need it because of the mechanical pump, so i am under the understanding that all i need to do to make this engine run is supply it with FUEL, and the starter with power.
also, how would i control boost with the variable-vain turbo?can i use a standard boost controller?
also, how do i SHUT IT OFF? i noticed there is a vacuum solenoid, and what looks similar to a throttle flap on the intake manifold...does this shut, choking the engine for air, thus shutting it off?
i was planning on hooking up a fuel pump relay to the ignition, and to this vacuum throttle thing, so whith ignition ON, the pump is running, the throttle is open, and all i have to do is crank the engine over and it will run...hopefully (glow plugs will be on a seperate relay, with a momentary pushbutton switch)
all or most of the sensors seem to be installed on the car.
do any of them give off a tach signal? (not TOO important, but nice)
also, is that the vacuum pump that is on the end of the cam?
sorry for all the questions, but this seems like THE place to be for TDI help
thanks!
