RB25DE question

[wicksy]

Hey guys,

currently doing a DE+T conversion, I have found this black canister mounted under my inlet manifold to have one of the small inlet pipes busted off. Wondering am I right in assuming it’s a vaccum canister? Secondly is this needed?, I am wondering what people have done when they go to a forward facing plenum.

see photo attached of the part. Thanks in advance.

It is a vacuum canister. I removed mine for a de+t conversion. If I remember correctly vacuum came from the inlet plenum to this and then out again to the variable air intake butterfly valve solenoid. Another pipe goes from the solenoid to the butterfly actuator. I diverted the plenum take-off to my boost gauge instead. And I disconnected all the tubes from the solenoid. So this was redundant for me.
