BPV Flange for Custom FMIC Piping

[achulz]

Hey guys, ordered my TR1035 just now.

I was looking at the CXRacing piping kit (from the RPM Store) and I decided instead of fussing with the kit and buying a bunch of couplers to fit the the TR1035, I am just going to make my own piping.

I am purchasing a 2.5" 304 stainless steel piping 'kit', it comes with a bunch of silicon couplers, elbows, t-bolt clamps, and some sections of SS tubing (straight sections, elbows, 45s, etc.). I can weld SS but not aluminum, my welding machine is DC only, you need AC to TIG weld aluminum. Plus I don't have the special tri-mix gas for aluminum.

I figure SS won't conduct heat as well as aluminum, hence why a lot of piping kits are aluminum, but it won't be a significant difference. After all that's why I got a huge TR10 core, so I can finally increase the power coming from my CS turbo.

Anyway. I need a flange for the BPV. I've found a couple do-dads that convert the Mazda style flange to say a Greddy or HKS, but I just need the flange itself, or at least an idea of what diameter tube it should use coming off the piping. I can fab the flange myself. Any ideas?

Just get a piece of 1/4" thick SS plate and trace the BPV flange. Cut holes, tap holes, weld to pipe, done.

Or get any one of the already available weld-on flanges for your aftermarket BPV of choice...although I'm not sure if they are SS or Alum.

What about the pipe size coming off of the IC piping? I know it's not going to be 2.5" like the rest. And I can't just weld the flange directly to the piping.
