SB EVO 16G Porting and Install on the 2G
Growing very tired of the T-25 I purchased a EVO 16G from slowboyracing and the EVO O2 from Conicelli's Anyway, I had to break this up in several pages. So lets start with porting pictures and comparison. Install page here
Turbo Comparisons

T-25 on top with 2G O2 Housing. EVO 16G with EVO O2 Housing on the bottom. |
 |
Top is the EVO 16G inlet to turbine housing. Bottom is the T-25 Inlet. |

Top EVO 16G Compressor. Bottom T-25 |
Porting Pictures
 |
New Turbine housing. Note the step.
|
 |
The step is gone and ported out. I found using WD-40
while porting helps a lot.
|
 |
Same deal. That nice step.
|
 |
Ported.
|
 |
The EVO Housing bolts would not fit the RSR downpipe
due to the distance between the EVO housing studs.
|
 |
Rather than cut the flange I carved the holes larger
towards the flange ends equal distance.
|
 |
Finished.
|
 |
This way I can be sure the downpipe and EVO O2 Housing
holes are lined up.
|
 |
I made a template of the J-Pipe (came with 2G install
kit) and marked the compressor housing. I port matched pretty close.
|
 |
Here is the turbine housing ported. I enlarged the
wastegate hole and turbine outlet.
|
 |
O2 Housing Ported and gasket matched (EVO 3 gasket,
not 2G). The gasket for the EVO is made for this setup. I did put
a 2G gasket on and noticed it did not fit correctly.
|
 |
The 2G manifold unported. Yet another step the grind
away. The die grinder getting a workout.
|
 |
Finished. I ported it to match the 7CM EVO gasket.
|
 |
The runners. I opened them up just a touch. When
I switch to a 1G head, I will port them more.
|
 |
Finished.
