These are the diagrams I have for the sequential turbo setup on my JDM EJ20TT

Was able to hook up most lines using these diagrams but still left with a few problems:

- what needs to be hooked up to the IC on the secondary turbo side here?


-Have no clue what goes here, it's where the air filter is connected to the secondary's BOV


-top of the manifold, same problem. Although the second line from the bottom right on the manifold (in the pic) might be it but that would mean I'm missing part of the line to connect the 2.


-the left hand side line that connects to the green (I think solenoid valve) directly beneath the manifold and next to the throttle body


All help is greatly appreciated as I'm in a dead end street right now with this.

on my car (2001 Lib b4)

The line from the secondary bypass valve (second photo) is hose number 22

Which goes up to one of the metal tubes that run across the firewall to the other side of the intercooler to a unknown device.



For the three hoses coming of the metal pipe to the IC one goes straight down to the (wastegateish looking thing). It looks like you might be missing that one. Also another one of them goes to the same device as the line from the bypass valve. I have some photos of these but im at work right now so i can't upload them anywhere. if you give me an email address i will send photos.

The ones on the throttle body look totally different to mine, i think my idle controller is right there. so i cant help with that much.

actually now that i look at those pictures you put up. Thats quite different to my setup so maybe my answers wont be a whole lot of help

looks similar to mine. what year is that one?

Mine should be a '96 model, at least that's what it says in the oil filler cap

ok mine is a 95. I'll go have a look.

the two lines go the the solenoid box correct. 3rd goes to a MAP sensor on mine.

that one goes to the map sensor also. mine has an extra line on there though.

on mine that dives down the back of the TB. can't chase it without pulling the whole lot apart.

thanks for the help Chris_Rogers

mine has an extra line on there though.

I've noticed that as wel on some of the TT engines I've seen pics of,must be different year or something.

no probs. I have one of these in a 88 wagon so I figured I could help.
