find a good welder and/or a good machine shop.

Also, when turboing the B20A5 you should really re-route the power steering line, as it would sit right on top of the manifold. It tends to overhead, and burst into flames.

I get $500 for manifold and downpipe combo. Manfold is all 1/4" thickness. 2.5" downpipe. Stainless manifold and 3" downpipe is more.

FYI: You don't want to use stainless for the manifold head flange or turbo flange. Stainless expands and contracts alot more than mild steel and you could have problems with your header/turbo bolts/nuts comming loose alot.

don't want to be a post whore or anything but um can u use mild steel flanges at the head and turbo, with stainless tubes in between? I don't think its possible to weld those up but i'm no pro so that's why i'm askin.

Yes its possible, you need to be careful what filler rod you use.
