A wise engine choice

Hello
I'm aiming for a 180bhp escort mk2.
These days, lots of engine choices are available. Some of which i'm trying to decide between are :
Good Old Pinto +- 120bhp
Zetec +- 136bhp
Duratec +- ? dont know this one, so leave it as it iss
RS 2000 (Escort mk5) - 150bhp
What would be your choice and why ?
I'm struggling between the Pinto and the Zetec. Pinto is easy fitment, lots of parts, higher tuning costs. Zetec is (i guess) lower tuning costs, good fuel economy, higher conversion costs.
