I have a 1997 LX
My valve cover has something along the lines of 'Multi Port Injection 2000' stapmed on it. It might not be exactly that but its close, I'll have to go look at it again.
Anyway, what is that? Is that Zetec, is it an option or is it just the stock 2.0?

It's a 2000 Split Port Induction. AKA 2.0 SPI.
No, It's not a Zetec, those are A DOHC, your's is a SOHC also know as a code name CVH.
