For the flange to the exhaust manifold -- looks like bolts are 3.25" and 2.75" on center, the over all flange is about 4.5" by 3.75", and the hole is roughly 3" by 2.5".

Anyone able to confirm I'm close? Turbonetics has specs online, but the damn .pdf won't open right and the flange dimensions run off the page.

Bueller? Anyone?

Alex - don't you have the dimensions saved on your computer on an image file?

AutoCAD!!! So useful...

Sorry to Hi-jack this thread, but, since we are on the subject of flanges. I'd like to find a special flange that I have seen before.
The flange is basically a T3 flange, with a split entry, with more material around the perimeter of it to also have the 4 mounting holes of a T4.

Here is a pic of it:

all markings in blue = the corresponding T3 Dimensions and all red = T4

Side note:
I know everyone is going to say just get a T4 flange, but this is for a special project (not M30) and some T3 turbines could be used and some T4 turbines could be used. and since I am unsure of which turbo I want without actually "feeling" it, I want to have the ability to just bolt on or bolt off with ease.
Sooo,

Where Can I find this thing???

Guess I should have been a little less precise and googled t3 too!
