NewTurbo APS SR40/Garrett Problem

[Lukezen27]

Guys

I've just noticed that there's no actuator connection on the turbo...

WTF?

The actuator hose for in the internal wastgate has no where to go!!!

What do you mean? Your photos in your build thread, show the actuator with the boost line connection and the shaft to the WG flap.

Yeah the actuator has a boost line conncetor but not the turbo like my GReddy kit had

What do I now connect the other end of the actuator boost line too?

[Nepolian]

Tap a new one in the housing or run it from the intake minifold?

Hows the build going?

Should be alot better than the D-Series :p

I would have thought there would have already been one on the turbo

You just need a boost source. So it needs to plumb in to your intercooler piping so it can read what boost is going in to your motor. For example, mine is plumbed in to my piping just before the throttle body.

Not always as alot of set ups now run external wastegates.

Baller build luke! I reckon you can spare a few $ for a external gate :D

The dimple on the comp cover is where you'd tap the outlet!

Yeah so the best place to tap it is just before the TB Yeah?

[VTi_b0i]

i think mines tapped into the turbo side of my intercooler

These guys say


For the wastegate, you will want to use slightly larger diameter hose. For the wastegate you will need a vacuum source that is close to the turbocharger, some turbos even have a fitting on the compressor outlet for a barbed fitting for the vacuum source. It is important to keep vacuum lines for the wastegate as short as possible. If the lines are to long they can delay the speed at which the wastegate will operate, not a good thing when regulating boost. If you are using a boost controller to regulate the wastegate then these vacuum lines should also be kept short.

My last turbo has the fitting on the compressor

If thats the best place, on the turbo I can get my dad to weld it there

[Nepolian]

WOW! Just tap your comp cover since its off the car.

The lines for my GTR were about 2 metres long end to end and it regulated boost fine. But I know where the statements coming from :thumbsup:

[SLOWEGG]

Anywhere before TB you should be fine, I had mine just after the cooler on the piping.

Tapping or welding the bleed to the compressor cover of the turbocharger will work.
This a default position used by many kit manufacturers & even OEM.
Nothing wrong with it; but gives boost based on that which is present prior to passing through the intercooler.
That is, it is a remnant from pre intercooler turbo days…
But it’s not the best way.

IMO, the best method is to use MAP, or manifold absolute pressure.
This will give you boost pressure exactly matching your spring pressure.
(Regardless of pressure drop across your intercooler core)
So my 5 cents worth is to definatly tap off the intake manifold.
(Between the throttle & the head)
Down side is some boost controllers don’t like this (when vacuum is applied)
You’ll be fine as you’ve got an E-boost.
But if you were using something else that has an issue.
A small one way valve would be the quick fix.

Hope that helps
Cheers

+1 rep point to George for still being on the money though now off the tools, LOL.

Hey bro run the line off your acuator and tap into the closest part of your intercooler piping ie the "hot" side with a fitting and put your line on there... with a small hose clamp.

you can run a line to the throttle body but the longer the vac line the more prone to boost spike / creep / line failure and line failure being the biggest issue causing over boost and usually bang.

^^ as above if you hav ean E-boost then spike and creep are no problem but place the vac line carfully :)

Any chance you have a photo of this?

I think is the next best thing to tapping the TB its self
