Hi guys,

Does anyone know or have a diagram of the factory 3 port plumbing. We are removing a EVC from a customers GTR and need to know the correct plumbing for the factory 3 port. Thanks.

There is a service manual linked from this forum:http://nagtroc.org/forums/index.php?/topic/27203-esm-my-xmas-present-to-nagtroc-esm/

already been thru the factory FSM it does not help as it does not show which vacuum lines go where.... i did find this (prodrive 3 port which is also a pierburg)

but i tried it like this and also tried swapping the actuator and return and its still overboosting..... just want to be sure i dunno if this one T's to both actuators or what.....

What suction pipes are you using. Some of them delete the factory fitting on the suction pipe as the HKS EVC does not use it.

Can you tell me what shop you work for?

Are you using with internal or external wastegates?

this is back to internal gates..... had a greddy kit now alpha 9.... turned out to be the forge actuators sticking..... i dropped the motor again today and am sorting it out now

as for the blocked off fitting on the suction pipe thats irrelevant as its only used as a return for the "bled" boost that is a byproduct of any 3 port.... it can be vented to atmosphere from the solenoid just the same
