My project is a Fiesta 1.6 carb '90, and I've installed a 1.8 Zetec into it. There are also 2.0 cams, 2.0 throttle plate, ST170 exhaust manifold and Megasquirt and EDIS systems. As the Zetec 105hp intake isn't the best intake there is, I was looking for something better.

I was offered a brand new ST170 intake manifold with injectors, throttle plate and everything. And this brings some questions to me.

I know I have to fix cables and wires all over again, but how about everything else? Does it fit between the cylinder block and the chassis? Without interfering the heater hoses?

And it also seems to have some 'variable lenght' -function. How about that? Is it 'simply' vacuum operated and easy to get working or is there something more to do? And what if I just bolt it in, does it work at all?

Not as simple as it seems mate! The st170 inlet will foul the brake-linkage bar, (hence why my engine sits about 1" forward than before).

Also the inlet manifold variable runners are controlled by a cable which is operated by a small black box containing some sort of servo which is then controlled by the ST170 ECU and generic electronic module.

This only operates at 6k rpm when it makes the inlet runners go from long to short to increase top-end power, which is combined with the variable inlet cam-timing to make the engine flexible at both low and high rpm.

To be honest mate, the extra power this alone will give when compared to the amount of hassle it will take to get it all running on your 1.8 will probably not be worth it!
