Get a jank-*** CDM turbo, boost that ---- to 1bar with a few heat cycles, then you'll be good with the real turbo. Or find a place that does ghetto extrude-honing for cheap.
FYI tack welding for the entire bead on a MIG is complete fail. If you beat is with so much as a wet paper bag it might crack. The basemetal doesn't get hot enough, and you have less penetration than an asian dick in a black -----. If your friend wants that psudo-TIG look, tell him to hold the trigger steady, but just move the stinger in spurts. Still not as good as a normal weld, but FAR better than a million tacks.

that caustic soda (NaOH) can be used to clean inside the manifold!? Anyone ever tried this?

dont use a brass brush use stainless.
1) brass will be eaten alive by the pipe
2) it wont last long
3) all that brass being worn is deposited on the steel
What happens is you waste alot of money for ensuring that if you ever get that spot hot enough to weld you'll have inclusions in the weld
It would have been stronger to braze it together with bronze filler rods.
i wouldn't invite any more corrosion into a manifold that it will see in service.
