I'll be taking delivery of a 2.5i soon which will be replacing my 2.0 carbed job, what manifold should i use to connect it to my standard e21 320/6 exhaust?
Cheers

you will need an E21 323i manifold, downpipes, middle box and the two back boxes!!

nothing wrong with the 320/6 exhaust manifolds, mine uses the 320/6 manifolds down pipes and center box.
just need to die grind the manifold out a bit to the 325i exhaust port size or youll have a 3mm step all round as you go from the head to the mani.

did you just weld up the hole that feeds exhaust gases to the carb then?

Do you mean the vent pipe that goes from the inlet manifold?

it goes from the airbox on top of the carb to the exhaust manifold.

Maybe cold start or some such shananigans? Roll on injection!!
