hi, just bought this car, Its a 150bhp version.

wanted to know if anyone has had any experience with upgrading the performance of this car.

I'm not looking to change the turbo.

also it doesn't pull/move much, there's something wrong somewhere, is there something i could do to check it out? There is no smoke coming out from the back so i guess that's a good sign.

Any help appreciated.

Thank you

With original turbo u can get max. 190-195hp out of it. Morelikely
what u get out is about 185hp/420nm. With automatic transmission
i suggest u forget the torque.

Quattro + A6 + (maybe automatic trans?) = slow motion acceleration.

If you are ready to upgrade the injectors you are ready to upgrade the turbo.

240 hp. +500 Nm.

Remaping+nozzles+turbo brings you some powah, like TDIfreak said.
I'm doing that modification later on this year ... probably.
First you need to change the turbo imho.

I can recommend also the new exaust from turbo to the end.
Original is great for big backpressure...atleast on A4. :|

With original nozzles you can get out about 210hp with(!) bigger
turbo. I know.

Hi all the ones that i've seen done had problems with either the turbo or/and egr system....which provented them from having a good tune so make sure the car is in tip top condition first.

Biggest problem with these engines is that the camshafts wear out early and you're looking at a bloody expensive repair!

It's not "if" it happens but "when".....

I had one, but sold it early enough

anyone know which turbo is inside this engine?

Is there a direct replacement tubro i can drop in?

Twin timing belts never knew that.

Would centralaudivw do me a diagnostics and service? Looks like i might need to make the trip down to simon

Thanks

It´s a GT2052V.

Use a Turbo from the 180hp V6 TDI like AKE or BDH.
A GT22 from T4 151hp AXG will also fit. This is my next Turbo for my V6 too.

The GT22 from Axg has almost the same 52mm compressor like GT2052V. So if you use it you will have no compressor upgrade in comparison to the stock V6 turbo.
