The cvh sump is nasty, The newest one you find will be 23 years old and will have spent its life in the worst posable enviorment.

Only do one if you need the shape to go over a steering rack / crossmember and your on a budged.

The Blacktop sump is better depending on the shape you need.

The turbo manifold is much he same as above. Power costs money but the more you can make the less it costs. The focus mani' with a td04 flange will be more durable than a cheap stainless one but not as pretty and if you can weld you would knock one up for £20.

Unless you have spent some money on the engine then the td04 on the focus mani will take you to the limit of a budget Zetec turbo.
