The standard 150BHP
made these engines pretty potent in
their day. As such the found their
way in any number of kit car formats
for use in rally, track day and sprint
racing. Our top-spec XE engine delivers
285 BHP and fantastic torque characteristics.
If you are serious about competeing
with this engine you should seriously
consider speaking to us.
Our measurements show a 14.9 % increase
in flow (inlet) and 21.5% increase
in exhaust flow. In standard form,
this engine gives 150BHP. We also
provide standard and big valve versions
for this head.
out our CNCHeads website for this
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. This helps us
make the most of the available flow
through the head and improves peak
flow and torque across the rev range.
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.
further details of how we specify
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 ECUsuch as a Motec 800 with
custom mapping. We also provide 4
and 8 injector fuel injection. We
also provide dry sump systems for
serious racing applications.
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.
