Hi guys. Starting to tune my ute and seeing some large boost numbers 1.2 bar and similar. Probably a bit much for std rods.
So chasing a 0.5 bar or so that will fit my big 16g.

Cheers fellas

I'm looking for a tougher wastegate actuator.

And I should have a good 8psi actuator kicking around

Maybe swapsies?

Is it a 1.2 bar actuator?

[jack be nimble]

I think its either a 1.0 with a bit of surge or a 1.2
I dunno if you would want to swap. This one had bent canister and I unpicked it and straightened it and put it back together.
It doesnt leak tho. Just doesnt look perfect
My money is on a 1.2. I was using boost tester up to 1.0 and I didnt notice it move. (Didnt actually watch it tho)
Up to you.

I couldnt work out why the ebc was going into alarm all the time with the alarm at 1.0. Silly me, maybe I need the spoon

[ChrisVR4]

I'll check out what I have when get the chance.
Can you send a picture of it?
I'm not too worried if its a bit damaged

[jack be nimble]

Nup, something else is wrong.
I tested this one and it starts to move at 8psi.
Maybe the boost solonoid is poo

Sorry chris. Thanks for reply, but this one would be no better for you either.

your probably getting some mad creep jack probably got a sticky flapper. my old td04 would get up to 15 pound and keep on got actuator was fine sticky flapper kept the gate closed

[jack be nimble]

Flapper flapping free. The wg solonoid is definitely a performance mod. It is stuffed and wont open.
I have replaced it and will give it a try tomoz or delete it altogether. ..

[leadfoot]

we talking the stock solenoid cause it's meant to introduce a boost leak. to increase boost pressure it's supposed to be closed when no electricity is applied and open when there is

[jack be nimble]

I may need to clarify its operation.
It connects manifold pressure to the actuator?
There is no bleed to atmosphere option?
It is a on/off tap that is off during normal operation?
When power is applied via the ecu, boost pressure travels through the solonoid to the actuator?
It doesnt leak boost but may hold it back until the ecu requires it?

I will log the wg solonoid operation as I am not sure of the way it works

[leadfoot]

ok this is how it should be plumbed (if it's a stock 2 port)

 

takes turbo boost pressure from the j pipe

goes into a T piece one port of this T piece goes to the wastegate

the other goes to the factory solenoid

the remaining port of the solenoid is then plumbed back into the intake before the turbo

 

the wastegate should NEVER see vacuum it does not get connected to the manifold

 

should be something like this

[jack be nimble]

Is that a wrx?...

[leadfoot]

it's from a subaru yes but our lines should be run the same way this is exactly how mine is setup with the stock solenoid

[jack be nimble]

I gotta think about this.
Mine is nothing like that, but my wrx turbo has many of those bits.

Mine has manifold pressure into the solonoid, then the output of the solonoid goes to the wg.

Yours makes sense to tho

[leadfoot]

no wonder your getting weird boost levels.

 

gonna move this to tech

[jack be nimble]

So the way mine is, It supplies boost to the actuator but it should be bleeding boost off...
My turbo doesnt have the nipple at the output tho.

[jack be nimble]

Hey chris, I give you plans for my tougher set up..

[leadfoot]

you'll need to plumb on in somewhere before the throttle body prefeably before the intercooler too

 

some photos of hows yours is might help

[jack be nimble]

And subaru schmubaroo.

[jack be nimble]

Where is the tit on the hot side of a b16g setup?

Im sure that my cooler pipes doesnt have one at all

[leadfoot]

On a Mitsubishi stock setup it should be on the j pipe the first piece of piping the bolts to the turbo outlet.
