Does anyone have experience with chopping off the stock flange on a manifold and welding on a t3 flange? Can anyone estimate how much a shop would charge for this?

dean

make a ad plate would be better i would think

SpankedYA!

The HMT NE install went like that. I think Bermanators Turbo is in the street by now though.

if its cast a lot of shops wont bother with it. i had 2 t25 flanges made for 35$. where i live at no shop would fool with it. i found a guy that welds on cast and steel i got lucky and found him. if you do find someone make sure they know what there doing when they work with cast.

let us know how that turns out.

Thanks for the info, is welding a cast manifold just a lot harder for some reason?

djfob

a bit harder and not as pretty.....I'd just make an adaptor plate

racepak

YES. its harder. first you need to heat the manifold and weld the flange while the manifold is hot.

FooK

yeah welding cast is generally not something you want to do.

people do it all the time with the d16y7 exhaust mani. cut the cat off and weld a turbo flange and there ya go. hmt style with no adapter plate.
