Stock Boost Solenoid

[(OO Black 33 OO)]

Looking to place the stock solenoid back on my car as having problems with the ebc, 2 holes, 1 above the other, which vacuum line goes to which hole?

Thanks ahead for any help, maybe a pic if there are any on here....?

Top hose goes to the wastegate actuator and bottom hose goes to the T piece

Cheers, hopefully help the car run better

ummm, i could be wrong but i'm pretty sure that neither of the hoses on the stock solenoid actually went to the actuator. one went to the T piece and 1 went back to the inlet pipe between the AFM and the turbo.

I'll go take a look at mine and double check but I'm pretty sure one goes to the wastegate actuator...?

if it did, then when the solenoid stuffed up it would run unlimited boost. also it would be pointless having it connected with a T piece. you would just have a hose go straight to it. the T piece is there because you have the hose go from the cooler pipe to the actuator so that when the solenoid is closed you get 5psi. then when the solenoid opens it bleeds off some of the air between the cooler pipe and the actuator so that less pressure gets to the actuator.

i am 99.99% sure that the second hose goes to the intake pipe, because when i put on my boost controller i just removed the hose with the T piece in it and put a new hose in and i only disconnected the solenoid from the T piece and nowhere else (blocked the hose as well so it could let any dirt into the solenoid).

Yes you're right. I had a look under the bonnet of mine and it looks as though it goes into the BOV return pipe which I'm pretty sure goes back into the intake.

Aplologies to the OP
