Hello friends!
Today well done turbo upgrade.

We bought the cartridges from Borg Warner and integrate them into the stock turbine, previously wasted on CNC machine compressor housing.
Balanced to 220000 rpm.
Completely sorted out all the details and all the new, actuators are slightly different , otherwise the turbine masterpiece, is no worse than FVD

 

if you can make a photo album with engine removal instruction , that would be great

 

I'll try to take a photo if I present when removing the motor

 

Turbine compressor✌️

 

Lets see how much hp this bad boys will produce on low boost

 

1,2bar( 17,5psi)- 730hp
1,3bar( 18,9psi)- 760hp
1,4bar( 20,4psi)- 800hp

 

Turbos are in

 

Looks like new

 

In progress...

 

we decided not to remove the engine , it is easier
