Slightly different Duratec build...

Hi All,

I was posting on here a while back since even though I have a totally different car from a Focus, it does run the fantastic 2.0L Duratec engine.

The car in question is a 2010 Caterham Seven, things are a little different being that it drives the rear wheels and then engine is turned 90 deg in the engine bay. The car came with the most basic Duratec setup, essentially a new 2.0L crate engine, switched out oil pan for lower profile and more baffling, and a big single throttle body intake (Caterham) and a Cosworth fuel rail.

Below is a picture of what the car looks like, I'll dig up some early pics of the engine bay before walking through the mods I have made since having it.

Catrams just look like fun. What are your plans? Rangers had the engine oriented like yours so I'm sure some people are sum what familiar.

Since then things have changed a couple of times.

First I bought the 2.3L Ford Racing head (bigger valves, CNC machined intake ports etc) and some Crane Stage 2 cams, also needed to upgrade to an unlocked ECU (from MBE) and get bigger injectors.

Those changes got me to the attached dyno charts:

Thats awesome & looks like a lot of fun, fun, fun. What kind of mods do you have in mind? What do you turn the motor at?

A few months later and some tinkering with different intake filter setups I switched to a really decent K&N filter and did a little more tuning.

The numbers improved..

Up until about a month ago my rev limit wast 7200 rpm, I have since upgraded the rod bolts and bearings and the new limit is 7750. In a few more posts you'll see where it is at..

You can just see the air filter that helped bump the power in this picture:
