I wasn't able to turn up much in a search. Surely, people have modified their crossovers to accept a T3 flanged turbo? Just curious to see what's been done, and what methodology was involved. My understanding is you'd need to use a 304 or 316 stainless flange, and something like an Inconel 625 rod. Any other tips from those who have BTDT? Plan is to tack it up on my engine first.

We used a rod for stainless (forget which one) when we welded a new pipe on.

We cut the pipe from the after the 90°bend coming up from the engine. then because we don't have the steering rack where we just had a pipe going straight up and another 90° into the turbo. was all stainless.

Thanks for the info. My recent progress with the turbo setup has me revisiting this situation.

I found this 304 SS weld flange, which would adapt the T3 hotside to 2.5" piping:

That would allow 2.5" piping to come down the vertical portion of the crossover. At that point, I'd need to adapt back to the crossover, which is somewhere between 2" and 2.25". I figure I could use this:

Anyone see any possible hiccups with that plan?

Another thought:

Start with a normal flange like this: http://www.ebay.com/itm/CXRacing-304...-/251890714730

Then, use this to get to 2.25":

At that point, just use 2.25" 304 SS tubing to mate to the crossover vertical section, such as this:

Would this be a smarter approach than Post #3? It would involve welding mild to stainless, and then stainless to inconel.

Also - I've read references to slotting the holes in the original flange to accomodate T3. Is that completely out of the question here?
