Heads up on your cold air intake - I tried the same thing on a regular Duratec and had resonance issues serious enough to stall the engine. I had to make the stock airbox work since it included a resonance chamber.
Thanks for the heads up. One of the notes that came with the ECU is that the engine HAS to be tuned if there are any changes to the intake so I am expecting to take some time with that. I'm not all that stuck on the design was going more for a what fits atm although I don't think it's too far off from what the mk3 focus crowd is putting on their cars.
Spent some time getting the primary tubes welded and the welds ground down (a bit of vanity) but only after running out of mig wire at 8pm on a sunday. This is the first set of headers I've made and I'm pretty happy with how they've turned out. Hopefully they actually work too. Need to finish up the welds at the flange and add the turn down after the collector and an O2 bung. Then I'll spray it with some primer so it can be painted properly some other time when it's not >80% humidity (see most of the summer-current this year in the mid atlantic) and the car is running to cure the header paint.
