1992 Range Rover Classic
ECR 4.6 engine install
This Range Rover Classic has come to us from Tennessee with a 3.9 V8 that
has some major problems. The cure we have in store for this Rover will
not only fix the engine problems, but will give it more power and better
fuel economy. That cure is to install a new ECR 4.6.
Here you can see the new fully balanced ECR 4.6 installed in the engine
bay of the Classic. As you can see no modifications are required to install
our 4.6 and they run with the stock gearbox and radiator without issue.
The ECR 4.6 is pre-modified to be able to bolt into your Rover. We have
been doing 4.6 conversions since the 4.6 come out in the mid 1990's and
there is no down side. We have done so many 4.6 installs that we did not
fully document this one, but if you want to see the process of a 4.6 install
you can see it on many other pages of this web site.
The only modification we need to make is to install a new computer chip
into the EFI (Electronic Fuel Injection) computer. This lets the computer
know that it has a 4.6 under the hood and improves performance, efficiency
and still retains all the correct diagnostic codes and serviceability.
Most chips from UK suppliers eliminate your warning light diagnostic codes.
This means you can drive for years without knowing your engine is not running
correctly, or at top efficiency, and with gas prices on the rise, efficiency
is the key. The ECR chips retain all your stock functionality and also
increase performance. In the image above you can see that we have removed
the EFI ECU from the Rover and have installed the new computer chip (stock
chip shown to the right). Once everything is assembled we will put on some
test miles to make sure everything is correct and then get the Range Rover
ready to ship back to Tennessee.
Here you can see the Range Rover Classic completed and ready to head back
to Memphis, TN were the owner will enjoy the power from his new ECR 4.6.
Everything works and appears as stock on this Rover, but in driving it
you can feel a major difference. The motor now runs smooth and with lots
of grunt. If you have engine needs for your Rover, feel free to contact
ECR, we can install a 4.6 in any Rover V8 powered Rover, from Discovery
to Range Rover.
