You have the Zetec SE (Sigma) which was launched with the Focus.
The MK2 has the same engine and was additionally available with VVT.
The same engine is still used now in FI guise, just rebranded as ‘Ecoboost’.
The Zetec E is the 1.8/2L and are Mondeo engines (the latter is also referred to aaa a ‘blacktop’.
The engine you have responds well to
cams. For the power you want I seem to remember this at at the top of the tune and think cams, tb’s and an exhaust.
Shawspeed are the timing exprerts for these engines.
