Differences on ST170 Engine (Zetec Turbo)
Hi,
Im thinking of building a zetec turbo engine using karlos G's great guide, but for my application it will be a RWD sierra it is going in...
now this gives me a few small issues..
1. How do I identify the ST170 block out of the car..
2. I believe this engine is based upon the black top engine, and from reading up the sump from a CVH doesnt fit as the blacktops sump is a 2 piece unit - what solutions are available to this (all googling seems to find me silvertop questions)
3. What turbo is best for ~200 bhp?
Thanks
Nath

Hi mate, glad my guide is helpful!
What is the issue with the sump, why did you want to fit a CVH one?
Turbo for 200bhp I would use a MK1 Focus RS turbo and manifold, will be spot on as essentially it is just a black top Zetec like the ST170.

From the reading I have done online, the CVH sump (from a sierra not RST) will allow this, as they bolt straight up to the silvertop but the blacktop has a 2 piece sump..
Im only just getting my teeth into this part of the project - the car is not long ready for mapping on a sacrificial 2.0 Sierra DOHC (using Megasquirt) and a bit of fun this year - whilst I take my time to build this up to be dropped in towards the end of the year..
