hi mate, the bellhousing bolt pattern is the same as all (i believe) ford bellhousing bolt patterns are the same, so any box would bolt to the zetec it just depends on the flywheel/clutch.

I looked into the options and i found that the only real option was to use a custom flywheel from TTV racing(http://www.ttvracing.com/), which will accept a cosworth clutch and starter motor. The type 9 box wont take that much power and i dont spose the ratios would be right for a turbo car, although u could buy a flywheel from burton power which is suitable for a pinto clutch and type 9 box. I havent ordered mine yet - next on the list.

Technically you could use the standard zetec flywheel with the T5 box but u have to find a suitable starter motor as the bell housing puts the starter in a different position which wont engage the teeth in the zetec flywheel. you can't use the cosworth flywheel as it is a different bolt pattern on the crank. I think that you will pay more for a zetec clutch which will be up to big power as opposed to the more common cosworth clutch, so shelling out for the custom flywheel (£188) is probably cost effective in the long run

The sumps are £470 from burton power, i got mine second hand and i can't remember how much i paid for it - 300 i think but it has had the oil return welded into it as well and it also has the optional extra windage tray. They dont come up very often second hand though, i was looking for a long time.

I noticed that burton have started to sell a cheaper stell sump though so that might be worth a look?

Hope that helps
