Hey guys, How did you get to the rear boost vaccum lines? There is no way I can get to them. ( I am using stock turbos from a jdm 1jz). Is there an alternate way to connect the boost controller to the BOV? Thanks!

 

Am I stuck doing it this way? Again how to get to the rear???

 

You're more on the right track with the diagram in your second post. The boost controller does not get connected to lines for the BOV. I know on my Supra, the line between the inlet on the turbo housing and wastegate actuator is the one that's tapped. I'm not exactly sure how it works with twins.

 

Thats what I thought... rats

 

bump for some info. how the hell do you get to the rear turbo waste gate line? my hands are way too fat to get back there.

 

I recently did this on my 1jzgte exactly how the diagram is. You have to remove the inlet on the rear turbo. It's 2 12mm or 10mm bolts. Use a ratcheting wrench if you have one. It was easier. You will have to remove the water line, bov vacuum line, and crankcase ventilation hose.

It wasn't hard removing. But putting back the inlet was hard because the gasket was kept falling off for me. It would be easier for you because you are LHD so you have more room over there.

You just have to look at what needs to move to access that area. I also blocked off the crankcase vent on both inlets and installed a catch can for both lines with a breather filter to prevent oil going into the turbos.

 

any way it can be done without removing the coolant line?

 

The coolant line is connected to a bracket that's in the way. It's only a clamp that needs to be removed at the top and it pulls out. Once your remove the inlet, you can remove the bracket. I even removed the stock bov so it's not in the way.

 

ok cool i think i can pull it off now. thanks for the info.

 

well i think my hands are too big or my tools suck because i cant get to any of those bolts.

 

You could do it without removing anything just get someone w small hands. I dont think you will find anyone to fess up to that though. lol

 

true. wonder if i can get to it from the bottom of the car. maybe on a lift.

 

LOL this is getting comical. Hire a 10 year old that is home for the summer

 

ahh my step brother to the rescue.
