Is an 8-bolt T3 downpipe flange a standard part? With a port for an internal wastegate?

This is my turbo.

well if you mean by standard.. common then no, most t3's are 5 bolt flanges. They have a flapper for the internal wastegate to usually.
Hope this helps

 

that's not standard but I've seen a 4 bolt flange for that on ebay

 

That helps, thanks.

Yes I was wondering if I could order a 2-port 8-bolt flange online or something so that I cold keep using my internal wastegate and allow it to breathe freely.

I have a 4-bolt flange. Is it a good idea to make an 8-bolt flange, or will the steel warp too much too easily? Do you guys think I could weld a pipe coming out of the block-off plate thats there (I wont be doing most of the welding, but will be learning how during the install from someone with a lot of experience and a good welder)?

Thanks again.
