I can't restamp it on cos i don't know what it is supposed to be
To cut a long story quite short, It is a 1800 zetec block with a stage 3 Escort RS turbo head ,stage 2 turbo, plus a few other mods to make it produce around 220 bhp.
I pulled the block out of a Xr2i 16v (on k plate i think) about 7 or 8 years ago and since then it has been in and out of a couple of cars.
I've never bothered about the engine number before cos i haven't needed to
I've tried a bit of wet and dry and carb cleaner to no avail, i think i'm gonna have to try harder
