has anyone welded a 3" dp righ to the dischage flange on a t3/t04e? is that flange wide enough? might be a dumb question but just wondering before i order my discharge flange
im just not sure if that flange is too small, will i have to weld on a 2" or 2.5" pipe first then flare it out to 3" or is the flange wide enough to just wled on the 3" pipe?

Wont fit..
I used one of these 2.5-3" machined transitions from atpturbo.com:

I had to use allen bolts to secure the flange to the turbo though,
since there is 0 room for a wrench/socket after you weld the transition on.
Works perfect though, and looks great. (I have a 4bolt turbo).

 

so 2.5" will fit, then it flares out to 3" it looks like? i have a 4 bolt discharge too

 

Yep. But you pretty much have to use allen bolts to attach the flange to
the turbo. No big deal, since you can pick them up at the hardware store for cheap.

My setup is actually:
4bolt flange -> 2.5-3" transition -> v-band setup

 

i would probably just weld 4bolt flange-transition-3"dp
awesome, thank you very much sir

 

I didn't order that one, but I have a 2.5" transition to 3" on mine to. It's a 1.5" transition, I believe from Burns Stainless... Works GREAT for room for the bolts.

Allen headed bolts sound like a great idea, too... I think I might pick some up when I go to Lowe's!

 

i have a 3in welded to my 4bolt flange, was kind of a pain in the ***, using allen bolts, im gonna re-do it and go 2.5 flared to 3

 

Any ideas where to get the Five bolt flange with a 2.75" or bigger hole in it? I got the one from atp and the whole is tiny.. I had to spend all sorts of time porting the thing just to make it close to the turbo outlet. For example I have the transition from ATP.. the transistion fits inside the turbine of my sc61. And the flange they sell with the transition needs about an 1/8" cut off each side just to line up right.

 

Double121 modified his revhard downpipe, to 3" with a/c, he bought a welder and hacked away. The drop/turn is real sharp though in order to clear ac compressor.

I just have a 2.5 that flares to 3"

 

thank you for all the info and help, i never knew about those transitions

Mine is 3 inch welded right up to the flange. Some studs on the turbo will work. The pipe just has to be dented in a tad.

 

You could alway make or get one of these from cheapturbo.com,it's a 3" V-Band clamp welded onto a bolt-on flange....or buy mine,its brand new,ill sell it for half the price I paid for it from cheapturbo cause im not using it,I going with a 4-bolt garrett...$85 shipped
