Zetec information and development

[Cobra289]

Hi,
We have bough the Zetec Black-Top and now we are in the process of match all the other components.

The gearbox [MT75] is perfect it fits with 5 main bolts [not only 4 like some one say] but we have here a left hand drive gearbox.

The start motor from a Sierra fits against the gearbox, but some rework is required to the aluminum sump, nothing special because it is not part of the oil containment, just a reinforcing for the traversal boxes.
We don't need to remove the alu oil pan to do it.

The inlet manifold is very restrictive, the TB has flap with a thick plate at the rear side, and it is very small.

So we have decided to make one our self.
First we have done some 3D design to see how all the components will fit.
We will use all the Zetec components, like the injectors [200 cc @ 3Bar] the fuel rail, the IAC, etc.
The injectors have 4 jets so we are not allow to rotate them, to maintain the good fuel distribution.
Also the injectors should be as close as possible to the inlet valves [spray on the valves] for that reason the injector location is critical and at the top of the inlet manifold flange.

So here are some pictures for information. Some of them are 3D drawings that shows the space and the development.
