i just picked up a new turbo, and the flange is a little bigger than the standard Ford flange. is this whats considered the Mercedes 5 bolt flange?

The mercedes turbines are not 5 bolts. they have a square 4 bolts outlet with an odd shaped turbine integrating a piston type wastegate.

the t3 stage 1 0.48 a/r turbines with a slightly larger 5 holes flange come from the late saab 900 i think. The last year or so they were using T3's. That was to correct the dump hole cracking problem. They seem to have succeeded. I have never seen such turbine crack.

your link is dead. actually, the whole BMC site seems to be down....

 

link works for me...

the pic they have in their description is a 5-bolt flange that looks just like my Ford flange. my 2 snails side by side look like they have the same DP flange, but the hybrid is definately bigger...

where would i find this flange?

 

Yeah the link works now. Sorry.

Yes, it appears that they are calling this 5 bolts flange the mercedes flange!!!! :1
i don'T understand....
AFAIK, no mercedes vehicle is using that 5 bolts pattern turbine. I though it was only on ford 2.3L, Saabs, renault, peugeot and volvos...
