Turning up the wick to Cobra's Stage 3 Power Upgrade
kit and things are starting to get very serious. As
previously explained, whereas some aftermarket
tuners suggest that the quality of the 4.0-litre
engines internals are capable of withstanding much
higher than stock torque loads, we do not believe
that in the long term the connecting rods will
provide good service.
Call it overkill, however at Nizpro we are more
interested in ensuring our customers receive a
product that we have absolutely no reservations in
supplying. Granted, some engines may handle 450 plus
flywheel kilowatts, however the question remains for
how long. If an engine breaks, the damage will be
significant. The alternative is to provide
prevention rather than hoping for a cure once it is
too late.
This package is quieter and smoother than any other
BA/BF aftermarket forged piston engine on the
market.
Performance
Engine is now capable of 450 rear wheel kilowatts.
Pricing
Price: Stage 3 engine kit is $12919*
inc. GST - Drive in, drive away.
*Note: Freight charges will apply outside
Victoria. Kit pricing is under the
assumption that you already have Stage 2 Plus
modifications. If not, then add Stage 2 Plus pricing
into your total figure.
The performance of a Cobra Stage 3 kitted vehicle is
simply astonishing in that it offers normal
drivability. In fact you wouldn't know that it was
anything other than stock in the way it drove, until
of course you nail the accelerator. Furthermore, you
are able to maintain (depending on how one drives)
stock fuel consumption figures and impeccable
driving manners.
