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

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.
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.
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.
