as long as its a ford race team.....
with thease convershions, its all about how much you know about fords. eg what cluch to use when your using a 2.0 zetec, with a 1.8 flywheel (1.8 so ka starter works) and then mounting it to a ib5 gearbox.
when you cant swap parts you then need to make them. i had to make a lot of brackets to mount ka alternator and pas pump. there may have being ford parts todo it, but i cudnt work it out, so spent a weekend drawing the parts i needed in CAD and using a CNC mill.
as you want throtal bodies, you will have to find some that will fit. im using a 2.0 zetec and i have about 150mm from the inlet to the bulk head. then you need a vacume feed for your brake system, which with jenvey ect you wont be able to, as they are for non assised brake set ups.
what im saying is, companys charge £1500 labour to do thease not that its hard, just lots of hours.
