Hi guys, i have mk3 Octavia from 2016 1,4tsi 150hp dsg7 motor CZDA. stage 2 could not hold stock turbo for long, it whistle like crazy.

So i decide to purchase brand new turbo from TTE.  First impression it looks amazing, wanted to install it, then i realize i got turbo

which i based on 1.4 golf  GTE.  They have Lambda on turbo hot side. my lambda is pre and post CAT.

 

I order bolt that wil fill the hole just like on downpipe without CAT.  one problem less.

Now turbo servo motor from GTE and my car, is also difference. does it have to be replaced or it can be adjusted like in VCDS?

 

also my turbo and GTE turbo difrent tech.  GTE have diesel like turbo that is ready from 1300rpm is called  Variable-geometry turbocharger or VGT.

 

our is  EWG  . Electric westgate actuator.   any help appreciated.  and i hope it will come some input before i start puting turbo on.  Tuning will come within week.

 

Surely you should go back to TTE and ask can they supply the direct replacement. A extra port for a lamda sensor is one thing but the turbo actuation and boost control mechanism is another. It may not work properly with your ecu - that's a risk surely?
