OK, back to the turbo work for a minute.
(Actually, a couple days of porting/finishing work on the Turbine housing)
Here's a couple pics that I posted above, but didn't really describe well:
After sandblasting the Turbine housing,
I prepped it with wax & grease remover(paint prep),
and then used the 2000° protection primer & paint and baked it in my gas grill(as per the instructions).
Here's how it turned out:
Having barely touched the WG port, or the exhaust chambers yet,
there was some tinkering with different tools to see what would work best for it.
The final decision was to buy a 6", canister type porting bit for the die grinder and go to town.
(I opted out of the reamer bit pictured a few posts ago for the WG port)
I'll try to cover this process the best I can here.
The flange is indeed a T3 flange.
However, as you can see, it's not "up to par" for performance.
Tracing the inside of the gasket, you see the amount that must go:
So, I got my grinder, porting bit, and a bowl to catch the metal dust,
and I began to port it out:
I found that working in one area, using constant movement, and allowing THE TOOL to do the work, is best.
So, I began on the side with the 9 cast into it(9cm housing)
After I got it close, I experimented with a sanding drum in my Dremel tool:
(Came out really nice, and I made the decision to use this method for the finishing)
Then I moved on to the other side of the flange,
and began cutting gradually out to the outer traced line.
(The angle you cut at, at this point is irrelevant. the idea is to get out to the edge and match the port.
then afterwards, the finishing, smoothing can be done)
After smoothing in the edge and sanding with the Dremel,
it looks something like this:
With the gasket:
WG port lighted:
I'll have to update the WG port work, but that came out well too.
What I did there was used the same 6" bit, and kept checking the port with this 18mm socket that measures 25.88mm(about 1.02")
I'll get the details of that work up here soon.
Thanks again for checking in.
Best wishes everyone!
