Stick standard plugs back in as the motorcraft ones are what works best in the zetecs, and the induction kit is probably loosing you power due to the heat soak, so I would use standard air box and a good panel filter.
Thought about throttle bodies? Only problem is anything that you do to it that is going to get good, noticeable gains out of it will require aftermarket management, shich is all going to be way out of budget.
Why not strip the interior out, make it as light as possible, put some ST170 brakes on the front and put some decent suspension on it, as that will make a massive difference to how quick the car is without touching the engine at all.
Throttle Bodies was on my list but the way i see it theres 3 different stages, 1 is put just a upgraded throttle body with the standard inlet manifold, 2 is do as mentioned above and stick the whole inlet from a st170, or 3 is stick some bike carbs/throttle bodies on it or weber aphla kit, but as you pointed out with management system be well out my budget.
I have found a JDM Turbo kit some has bought with all the fittings for a zetec, its new and never fitted, £600, but sinces it made to work with the standard engine im guessing its low pressure turbo. Also that would increase my insurance.
So what im thinking is decent set of FastRoad/Race cams, piper or kent, ST170 inlet manifold, fuel pressure regulator to help with that bit of lag at lower revs, and get it remapped and set up on rolling road.
Thought on that idea?
Thanks for input
