I just did this swap yesterday and did all the work myself including the welding etc. This writeup made it much easier, thanks for the info. I didn't have a machine shop do any of the work on the manifold though. I welded up the peanut coolant port then ground it down close to the machined surface then filed it down by hand until I felt it was good then sanded it with a piece of sand paper wrapped around a piece of square tubing.

As for the IACV I just filled it with JB weld. Still needs a tune but seems quicker already.

tried to do some searching on this, i cannot for the life of me find out whether or not i'm required to do the splicing/soldering on the wires, or if there is a different way to go about it?
also where can i find me some 8th gen 310 injectors?
i was looking into the PRL manifold gasket, so that i didn't have to do any machine work, and they offer the RDX injectors with pigtails (i assume to match ours for plug and play so no wire work??) for $220, good price?

i haven't done it yet due to some finance issues (moved into a new place, and had overtime cut at work, so i'm a little strapped at the moment)... keep us posted 323 and let us know how it goes!!
