Hi everyone, I'm new to this forum and have a question.

im currently in the planning stage of building a replica of the 05 WRC Ford Focus RS.

The project is starting out as a black 2003 Ford Focus 1.6 Zetec, but I want to do an engine conversion for the ST170 engine, reason being its really difficult to find an RS engine, not to mention the price of one. As well as looking like the real thing, I want it to perform somewhat similar too, so whats the absolute max you could squeeze out of an ST170 engine?

cheers.
