The unabridged exhaust flange handbook?
 

I was curious what you all knew about the different exhaust flanges available. So far I know the following list of the garret standards.

T2
T25
T28
T3
T4

The are also the Mitsubishi turbos which I believe are different.

What about IHI? They made some for the ford probe, and a couple other turbo 4 cylinders in the 90's. I guess there still around, RHB51, RHB52 ?

I wasn't sure which flanges were the same or at least compatible. I got to looking at it today, and it was amazing just how many types are out there. You'd think they'd stop reinventing the wheel and just stick to one. Anyone come up with a list, and maybe known sources of adapters? Drawings would be good but that's probably asking too much. :giggle:

There are flange drawings on the Garrett web site for their turbos.

I thought the t25 and t28 flange is one and the same?

a few more...

T25/T28 are the same, T20 is a small small flange with a circle opening instead of rectangle. I think the link Sixshooter just posted up has about all the different types.

Yes weirtech has pretty much everything. Its where I got my flanges and would do business with again any day:)

It all kind of came up when I realized I really had to turbo my car so I can test this new intake manifold. :giggle:

The mitsubishi turbos are td04/td05/td06. There are a handful of variations and hybrids from those ranks, and the newer td05s that are coming the evo X series of vehicles have vehicle specific outlet flanges.
