Help with 4A-GZE

[Gremlin]

Howdy guys,

Got a little problem i'm hoping that you guys can help me solve.

I have the 175mm Cusco Pulley fitted and i need to do the ABV/VSV bypass which i've found and tried, but i think the guy whi had the engine before me tried and did something really wrong... I'm gonna have to use pictures to show what it looks like.


now these are the "blue" & "brown" VSV's off of which are the lines that i have to play with, correct??




This line is from the Blue VSV and goes into the ABV.



Hopefully this line is going into the throttle body as i'm told that it should be.


This picute is of the Brown VSV and i think that its going to the Fuel Pressure Regulator



now this is where it gets wierd... this line is off the brown VSV and is t_pieced into nothing (the end is blocked off) and it runs through into this next picture



which has me really confused as it has a power socket, but nothing plugged into it...

My engine has no cold start attachment as it wouldn't fit in the engine bay (AE-71).

Now when i first started looking around in there and trying to follow the diagram i had to do the ABV/VSV bypass, the hoses running off both blue and brown VSV's were intermixed... i put them the way they appear in the pictures by using the diagram for the bypass as a guide, but i want to make sure that they are going to the right places so that i can do the mod properly.

Sorry for the long and confusing post but i thought the best way to describe my problem would be to show it with pictures... hope you can help... if u need any further clarifications i would be happy to help!!

Regards,

John

Just re-did the post with all the files hosted at imageshack... thanks for the tip hen, couldn't remember the name of the site!

hey mate.
you should just remove the ABV all together and cover the hole with some plate and a gasket. this is what i have done with mine, its so much easier and you dont have to screw around with the vacumn lines.

Just a suggestion.

[mullett]

Yeah, I agree absolutely. I still had boost leak even with the ABV hosed off like you're trying to do, took 5 min to make up a little aluminium plate to cover the hole. Plus you free up some room in the engine bay, looks better...etc etc.

what you can do is run the ABV vac line directly to the inlet manifold and then run the line from the vsv to the manifold as well. i think thats how it is done.

when doing the vac line mod to block the abv, you take the blue one out of the equation, that is no longer used, cap it all up. the brown one though, one side goes to the inlet manifol, the other side goes to the fuel pressure reg. put a t-peice in between the vsv and the inlet manifold, out of that t-peice goes onto the abv where the blue vsv originally linked to it

thanks for the replies guys,

1 last question... what's the thing in the last picture?? Is it part of something that leads into the Intake Manifold? If it is, then I assume that I tee into that then??

Thanks for the help,

John

It's the A/C idle up controller. The line to the inlet manifold you're looking is smaller and comes straight up off the manifold (next to the inlet pipe).

[Gremlin]

I need some help finding the line from the intake manifold...

From my Brown VSV, 1 line goes to the FPR, the other one goes to the A/C idle up controller (thanks for that Ben!)... from there should it go to the intake manifold? Cause there are a couple of hoses coming from that leading elsewhere...

Also, the 3rd picture up the top, is that line going into the throttle body?? I know the picture is positively craptastic, but i'm hoping that someone might be able to ID it for me

Thanks Guys,

John

It's been a while since I looked at standard ZE plumbing, but I'm pretty sure the AC controller shouldn't go anywhere near a VSV. It should hook up to the pipe going down from the throttle body. (that's on an AW11 motor anyway)

I honestly can't remember what the rest of that stuff is supposed to do, sorry.

[wiso]

no man that line in 3rd pic is the intake manifold one observe



the ac idle up has 2 lines off it, one goes to before the throttle body, usually up in that 90 bend metal pipe bolted above the throttle body, and the other line goes down just below the throttle body, if you look in ont he opposite side of the piping to where the charger is you'll hopefully see a vac nipple the same size

pull the abv off and cover the hole with an alloy plate and gasket goo simple .

Check out the vacume diagrams on the above post. Helped me out heaps.

Cheers

Yeah, as wiso is saying the AC idle up comes pre and post throttle, but it has a much larger diameter hosing. Around 1/4" rather than the piddly little vac hoses which the other lines use.
