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
Not sure what the point of using an st170 inlet manifold is, unless you will be swapping over looms/ecu etc to run the VVT, as that is the only difference. I don't think it has ever been done before as you would also need to change the inlet cam too as that is variable, which would mean changing over to an st170 head.
A fuel pressure regulator will do nothing on a car with fuel injection, it's all a big gimmick! If you do somehow manage to get more fuel into the engine, all it will do is make it run rich, thus lowering the performance anyway.
Cams sound like a good idea, while it's all apart you could stick some bigger valves in and get the ports opened up a bit!
