Always suprises me that people are still so keen to use them, their not massively reliable and 200hp is mega bucks where as a duratec at 200hp for example is probably bulletproof and I'd imagine would cost a lot less.

Personally best value for money is the Vauxhall xe engine, 200hp with just tb's and mild cams and the core engine is a few hundred quid IF you ever grenade it.
