Ford developed this engine as the
a true "world" engine. It's
been fitted to everything they make
probably. As a tunable engine it offers
lots of possibilities. For a start
it has an alloy block and head making
it very light for its size (which
of course makes it ideal for kit cars).
It's quite easy to get 200+BHP from
this engine without touching the engine
internals. The standard engine has
some good internal feature such as
pistons which are close in size and
shape to slipper pistons. The valves
too are big (by most standards) with
nive thin stems. So the engine will
take some moderate tuning quite well.
Add a pair of 45 DCOE carbs, throtte
bodies and a new engine management
system and you'll get a fairly potent
However, if you are looking for more
than 200BHP and to make that power
reliably you need to look fundamentally
at a number of items. Our top spec
Duratec runs up to 300BHP. To achieve
this we look at a number of key components:
We put a great deal of effort in
to improving the flow through the
head. Improvements here benefit every
other improvement in the engine. Or
to put it another way, all other modifications
will be restricted by the standard
head flow. We found an extra 17% inlet
flow and a huge 34% exhaust flow. Our aim was to get 300BHP or more. With this head we are able to achieve that.
as part of our cylinder head development
we are able to specify a matching
set of camshafts which match the flow
profile of the head.
having a fully balanced and lightened
crankshaft has a huge effect on the
balance and responsiveness of the
engine. We give the crankshaft the
full treatment on our CNC crankshaft

Rods and Pistons
Over about 230BHP you will exceed
the reliable limits of the existing
rods and pistons. These are replaced
with top spec items. We look carefully
at the specification of these items
to match the intended purpose so we're
not tied to one particular brand.
Where necessary we make minor modifications
to suit our needs. Again these items
are fully balanced with the crankshaft.
ECU and fuelling.
This depends on budget and application
. For instance for trackday purposes
and basic twin webber carb and basic
ECO setup will suffice. For top end
racing applications we provide a puuka
racing ECU such as a Motec 800 with
custom mapping. we also provide 4
and 8 injector fuel injection.
Each of these engines is bespoke
according application and budget.
We don't supply crated engines or
"box shift" and build components
from other vendors. When you talk
to us about an engine you will receive
all the attention deserving of a bespoke
service. The results are exactly as
we specify and ultimately measure
on our dyno. We don't make false promises
on power. Come down and see the power
YOUR engine makes on the dyno and
know that the engine in your car is
the best it could be.
