Garrett Medium Frame Gtx Turbos

[ARTZ]

Has an AVO HD actuator, i would of thought it would be sufficient..

Trent is a magician and if there is a problem i reckon he will find it but , is it wrong to say that there is every possibilty that this is just the nature of the turbo as AVO have said..

[Tangles]

you can see in the second photo the actuator is rated for 12psi.

with my GT3076R 'highflow' (45v4 Nissan ported comp.housing, garret chra, avo .73ar 6-bolt skyline exh.housing) I originally had a 12-14psi adjustabel HKS actuator.

Wasnt happy with how it came onto boost and spooled up to 1.1bar, sold the hks actuator and installed a 18psi garrett actuator, seemed to make a slightly better difference in how the turbo performs overall. The 18psi garrett actuators sell on ebay for $120 delivered. Buy/sell and feel the difference.

Definately a thought. They are gonna sting me for labour though.

what fuel pump you using?

Its one of the things you should be doing yourself, it is a 10minute job to uninstall the current actuator and bolt up a larger 'heavy duty' garrett actuator.

If I can do it in a quarter of an hour, being 200cm tall with no knees and fast-fading hips, with hands on the large-side, you can shit it in easy.

f**k mate ill put a WG on for u

Wont it mess with my boost. Currently I'm assuming the actuator bails at 12psi then my gizzmo holds the rest. Wont either my gizzmo be useless, or I boost higher than my tune if I swap actuators?

[ARTZ]

shouldnt make much difference will just make life easier for your gizmo id imagine...

Fuel pump dude? you have changed it havent you

[Tangles]

I use a Greddy Profec-b spec-ii in conjunction with the 18psi Garrett actuator.

The EBC will allow you to modify the 'Gain' settings etc to bring on the boost as best as possible.

Yup wallbro 550 nvm about.my above question. If I get an 18psi HD actuator. I Gota make sure I'm not tuned to 17 or sumthing. Wichita I think I am. Changing the actuator will mess.with that.

But your running at least 18psi right? If someones running less and they put an 18psi.actuator ones the gizzmo release the actuator will still cause boost to gain.

No, I dont believe it would be an issue in regards to the tune. Setup the EBC you have for 17psi with the max setting of 18psi.

ie I have the 18psi actuator, my EBC is set to 1.1bar and 1.2bar low/high settings, which is equal to 16psi low 17.5psi high.... I dont have an issue

(however in saying that at my last track day I broke ringlands on piston#5; oil "somehow" got onto the AFM, half a lap of WideOpenThrottle later and rings let go)

You can purchase different psi-rated actuators, I believe 12-14psi, 14-16psi, 18psi, 20psi, etc

here is a 16.7psi actuator - http://www.ebay.com.au/itm/Actuator-16-7psi-/300550937648?pt=AU_Car_Parts_Accessories&hash=item45fa3b5c30

Yeh I thinks it's safer to go slightly under my tune. 16.7 paid seems good.

The car is going to avo Monday for the day to adjust cam gears and see of the actuator.is causing issues. Then into Trent on Tuesday lol

Also that's just a generic actuator. I'm specificalygoing Garrett HD.

Just hold ya horses. Wait till Tues night.

Then worry about "where to" with regards to changing parts, more labour etc. Patience for now, there is no obvious reason to spend any more money on parts at this point.

Ill rephrase. "I would go a proper garret actuator instead of something generic" if needed.

[ShiftyTys]

Well its being dropped off tonight after I pick it up from avo. Donations would be appreciated.

[ido09s]

I would always have the tune checked after doing an actuator change/boost controller reconfiguration. The actuator may allow the turbo to make more/less boost in certain areas of the map therefore messing with the tune.

Yeh definately. That's a given. Left it there tonight. Appears to be in good hands. Seems pretty cluey!

Here's hoping it comes back a monster!

Perhaps a definitive answer on AVO's business ethics while were at it. We can see if they really were just too lazy to do better for the customer.

Avo have been very good to me. I just want fresh eyes on the chart. Trent did comment that the boost curve looked kind lazy lol. Anyway. We'll see.

[wolverine]

I am looking forward to seeing this set up working at its potential.
