I have an SC61 with a turbonetics T3 manifold. Thing is, when the wastegate mounts right off the #1 runner it won't clear the hood on a 1g, so I will need to make an EWG adapter pipe to angle the EWG to clear the hood. I also have a 5 bolt turbine housing on my turbo like the picture below, so I will need a custom o2 housing (Unless someone here has a link to one that isn't an Ebay peice of junk, because I couldn't find one anywhere)
So, here are my options:
Option 1: Custom o2 housing with custom WG adapter. ( EWG mounted on manifold)
* Is it bad to block off the wastegate opening on the turbine housing with a solid plate as the base for the O2 housing? This is one of my main concerns...
Pros: already have all the main parts, flanges included.
Cons: not much room, kind of a complicated setup, one extra WG gasket to leak.
Option 2: Custom o2 housing with EWG off o2 housing similar to
this (post #5), and get an FP Race with T3 adapter plate (already have one)
Pros: Simpler design, would take up less room due to not having an adapter pipe for the EWG.
Cons: Don't have an FP Manifold, one more T3 turbo gasket to leak.
My turbine housing:
My manifold and turbo setup:
Pretty sure I will be dumping the WG to atmosphere also.
Also, has anyone here used one of these turbine housings? I have looked at ATP's site and it looks like they don't sell them anymore. This could be a third option, to have the wastegate and dumptube mounted right on the turbine housing, would take up the least room, the only problem would be finding the correct casting to fit my turbine wheel/CHRA.
Pro: least piping, most room
Con: not even sure if ATP makes a turbine housing the right size
Any pro's/con's I may be missing here?
