Will Pedley Racing – Focus ST170 ITB conversion

Remember kids – if you have a cam cover powder coated – take the baffle plate out and check for debris before you fit it!!!!

This was what i found…

After a very thorough clean:

As it was 10pm by this point I called it a night 🙂

Hopefully tomorrow i’ll get the engine dressed and the cams timed in etc.


Well, a few pics from todays work:

Started out with timing the cams in – dialled them to standard positions first:

Then dialled them to specified peak lift figures:

After some tweaking and modifications – on went the throttle bodies:

Then the exhaust manifold and heatshield:

So tomorrow is only pumps, alternator and an auxiliary belt away 😀

Q: those trumpets look huge. Will they fit?
A: I have raised concerns regarding fitment and even tried ordering shorter trumpets – the supplier remains adament that they will fit.

As soon as we have the ECU and wiring loom (been on order 6 weeks now!) then i’ll do the appropriate installation mods and then the engine can be fitted – then we’ll see how it fits…

It is also going to run filter socks as well just to stop any nasties making their way in!

  1. Brill write up, fantastic even, so glad that this has been looked at before I venture down this road,

  2. Hi Jonathan,

    Glad you like it – I’ve merely borrowed the content from Will Pedley a means of showing the importance of Search Engine Optimisation – although it is my car!

    If you’re looking to do something like this I would say without hesitation to give him a shout http://www.willpedleyracing.co.uk 🙂

    From your e-mail (which isn’t shown to the masses) can I assume you have a Fiesta? I can only imagine how quick a smaller car would be with this engine :0)
