AAN into Ur quattro, 400-450 Bhp Target

[DJones]

Its impressive how small these new turbos are yet still able to deliver such high output figures...

Looks good. The 2 maps on the one scale show just how big an improvement in surge and low down boost compared to the 71r. That combined with the smaller turbine will really help response and still do 400 to 450 hp at a push.

Looks bloody lovely keep us posted on the turbo swop and good luck, watching this build with intrest.......mark

big time.

In theory yes, we will have to see!

Yesterday wasn't a good day

First I couldn't drain the oil as the sump plug is rounded, (like this from before when I had to put it back in so I could get it mapped)

I have a new bung to put in and planned to change with this oil drop, but my previous methods of mole grips and hammer didnt work. Tried some plus gas and heat too.

In the end I sucked the oil out using my vacuum fluid extractor just so I could remove the turbo.

Turbo is off. I will post some comparison photos of the two turbos later on.

However, when moving and taking off the exhaust turbine on the new turbo I somehow managed to let the centre hosuing and compressor hosuing fall on the floor.

Careless! Can't believe I managed to do this!

As a result I think the tips of two exhaust turbine blades may be bent over slightly.

All I can say is at least it wasnt the fancy billet comp that may be damaged.

Unless I am imagining it? Inconel is pretty hard isn't it?












GT3071R turbine for comparison;




I also have a video:


*Phone wont upload to youtube, will do this evening*



what do you think?

All I can say is oh B*lleux!!!

What now, take it somewhere for them to check the balance and take a look??

any recommnedations of a Garett agent near Essex?

[Thuppu]

Ooh noo, that hurts! Those blades are defenitely bended. Hope you can get it sorted out som how.

[prj]

Turbine wheel is scrap, also the hit could have damaged the CHRA...
Yeah, pretty much send it back where it came from, and you might get away with 300-400$ for a new CHRA through the Garrett program.

[URquattroGus]

$909 for a new Centre section! The turbine wheel seems to be the same as nearly all other GT28 series as below;

53.9mm and 76 Trim

If I can get a turbine seperately then have it istalled and balanced there is some hope.

Anyone got any ideas who might be able to do this?

The center section is not 900$
Talk to ATP, they have a special program, and you might be covered for a 400$ core change.

Buying the turbine wheel separately, replacing it, balancing and checking the entire CHRA will cost more than that.

[diesel des]

Oh dear. You can't get a turbine wheel and shaft seperate as you found out. Any gt 28 r could be used as a donor using your compressor side. Or you could put your compressor side on your gt30 turbine side. Turbo dynamics again could help. It's an expensive drop. Basicly you need a new chra, minus the compressor wheel and housings. Could be as cheep to get another turbo minus the turbine housing. I would be interested in that compressor and housing if you do need a second turbo. Could help to pay for the drop. Talk to atp and td...

[Ross]

Gutted for you!! I was expecting to see an update saying "its fitted and ready for mapping!" Hope you can get it sorted - perhaps a bit of a sob story to ATP and they'll sort it out cheap for you?

[Thuppu]

It can be possible to remediate the blades, but it should be done by a turbo expert and needs re-balancing of the shaft.

[prj]

Look, there is the garrett repair program. You can get a brand new CHRA for 400 bucks if you bought it from ATP.
Just go for it.

[diesel des]

Yep try atp first and talk to td. I wouldn't risk running that turbine even it was straightened. If atp can supply a core for 400 then ask for your bits back. As I say I'm interested in the bits.

[Acidburn]

edited for accuracy

it should be done by a expert who re-balances shafts.

- sounds like a job for madwolf

sorry to see this happen, I was looking forward to seeing if the gtx's worked well on il5's.
