S1 Rebuild(s)

[Dave Adams]

some pics of the rebuild process,

the top trailing arm bracket is broke......

the diff is sloping back a little (looking up) so that will need sorting.......

As you can see there isn't a lot of bracing in an S1 chassis, that will be sorted.

Cheers Paul. ...

Here Steve. ...when you cut off  the injection plate off the plastic plenum your left with this......this bolts to the head between the manifold I have made.

[Steve Kerswell]

Ah right, I see it all now :-)  I recently Tig welded some bosses on a alloy manifold for injectors to screw into, but that looks an easy way of doing it, so I presume the throttle is in the big bit bolted to the new bit?

[Dave Adams]

Yup the big red plenum at ataches to the injector plate....the throttle body is at one end....

[Dave Adams]

The Marlin yours Steve? or a customers car?

[Steve Kerswell]

I want it Dave, but can't warrant the expense :-((  I think the term is "skint"

[Dave Adams]

Ah....skint.......all my life know it well...

[Dave Adams]

Turns out the focus 1.8 is even more different than the mondeo  1.8..... the mondeo has two coolant sensors. One for the temp gauge one for the ecu. The fans are ecu controlled.

On the focus it has only one temp sender....behind the alternator. And I don't have the plug from the sender on the loom I bought second hand.....so I don't know what wire it should be.

Anyone out there got an 1.8 mk 1 focus and tell me the wire colour?

[Dave Adams]

Yeah it's an issue...I am running the water pump as ford intended.....some idle wheels will be needed.
the engines can be one of three types...zetec sigma and duratec the sigma has the inlet to the front of the car the duratec is a more modern engine. I need some details from a 2001 car or thereabouts....

[Steve Kerswell]

Now you've shown me yours I can understand why I did this to a sprint engine, it is still running too :-) you can see it was a twin weber inlet and the four bosses I welded on. Do the inlets from the plenum need to be so long for a reason?

[James Doulton]

The general theory used to be that longer inlet tracts increase torque. Something to do with having a long column of air to push the last little bit in as the inlet valve closes. I'm not sure that I believe it because it must also be a larger column of air to get moving when the inlet valve opens. The lengths are too short for waves to reflect back while the valve is open, you'd need over a metre for that. All I can think is that the longer pipes helps to reduce the turbulence, increasing the flow past the valve.

[Paul Sheridan]

The 1800 water pumps from an Escort run the correct way, enabling the use of a short belt, and using the alternator as the adjuster.
