First of all, Hi, I'm new here.
I also have to admit that I don't actually have an ST170, well not all of it.
This will sound strange, but I never liked the hatchback Focus, or any other hatchback for that matter ( no offence ). And although I have a lovely Ghia saloon, it only had a 1.6 engine.
Sorry, to cut a long story short, I stuck in a ST170 engine and hopefully will get the rest of the car finished in a couple of months, ( being optimistic).
Well anyway, I'm going to run a standalone ECU on it, and hopefully supercharge it.
I'm curious about the non return fuel rail, Does anyone have any info on it. I dont think I will be able to program the ECU for it so I will probably have to fit one with a return.
