V4 Vacuum diagram's or advice please
 

Hello,
I'm after a little advice as to where the vacuum pipework from boost solenoid goes to turbo/wastegate etc. After many hours googling and searching on here I think I'm more confused than when I started.
I keep reading about a restrictor pill and T piece between turbo/wastegate but mine definately did not have this when i removed the pipework.
I took pictures of just about everything but must have missed this out :mad::mad::mad::mad::mad:

My car is a V4 1998 Type R.
Any help would be appreciated (there seems to be a lot of unanswered threads just like this when you search on here?).

You must have a 3 port solenoid then matey!

Have a look at this:

Thanks for that, I found that last night although it looks different to my setup. I couldn't find any pictures of a V4 set up anywhere.

Here's a picture I found before it was taken apart...(with added numbers lol)

Yip, that's a 3 port you have.

Pipe 1 - Turbo compressor housing
Pipe 2 - wastegate actuator
Pipe 3 - main intake pipe before turbo inlet
Pipe 4 - Not sure, I'll look at mine later!

The car should have a 2 port not a 3 port......Can't say Ive ever seen a 3 port with a port on the left....Strange.

That wouldn't be the only strange thing Jay, I'm 99% sure the blocked off pipe shown should be going to the recirc?

Attachment 69620

It probably does, the recirc needs a vacuum....

Number 4 also goes to the inlet, its the pipe for the map sensor from what I can see.

3 port is a popular upgrade for better boost control. Leave it in there.

Yes, but you just can't go fitting a 3 port and expect the ecu to control the boost in the same way....

Certainly, but that would lead you to think that the car might already have been modified to suit.

The pipe you have labelled no.4 isn't on my car. There's nothing teed between my map sensor and the other solenoid. Has someone installed a boost gauge from that point? Mine is a 2 port setup and looks to be the same bracket/hardware as yours apart from you having the 3 port now.

OEM setup for WRX-RA.........

Again yes, if running an aftermarket ecu which i dont think he is.....are you Kwik?

Ecu is standard, solenoid is as it was when I bought the car. JGM iirc said some v4 have 3 ports but it wouldn't surprise me if it was fitted as an after thought.
Te tee piece is going off to the boost gauge in the interior.
