Ford Duratec 30 Tuning

"All you need to know about tuning the Ford Duratec 30 engine!"

In response to requests for additional information on customizing a Duratec 30 and, in particular, which turbo improvements work best, we've put together this page detailing our go-to modifications for this engine, as well as the most cost-effective ones.

Noble uses the Duratec 30 and by strapping on a couple of big turbos they can crank out around 450hp. I've seen even higher power figures if you are prepared to do more internal engine work.

The Ford Duratec 30 are popular engines and with carefully picked uprated enhancements like remapping, turbo kits and camshafts you will certainly enhance your driving opportunities.

Here we look at Duratec 30 tuning and provide tips on the premier modifications.

See our video which provides a complete introduction to Ford Tuning, it contains some tips on performance and handling modifications.

History of the Duratec 30 Engine

Introduced in 96, this V6 was used on most larger Ford models of the time, and were great engines, and have lots of potential for a project car. We have a general guide to Duratec engines, but in this article we will focus on the 3.0 Duratec 30.

A revision made in 2006 saw the introduction of variable valve timing. It was also branded Mazda AJ and Mondeo V6, but all are essentially the same engine block.

Best mods for your Duratec 30

1. Tunes - Duratec 30 engine tuning/remapping gives the most advantage in terms of your investment, aftermarket ECUs, and Tuning boxes are all alternatives.
2. Fast road Camshafts are are often the best upgrade for an engine, but ideally be installed by someone familiar with setting them up on your car and you might struggle to find one but there might be a local firm to regrind a stock camshaft .
3. Forced induction upgrades - forced induction is the most efficient approach to improve intake air supply, allowing you to combust more fuel and make more power. Typically one of the most challenging modifications it does provide the largest gains.
4. Flowing and porting the Head - Head work will get air flowing into the engine while removing turbulence or restrictions.
5. Air Intake and Performance Exhausts - Be aware on their own these mods won't ADD TORQUE for most setups, but they permit you to lift power after other upgrades by removing the restriction.
6. Flywheel lightening - a reduced weight flywheel will significantly improve the engines ability to rev freely. In some cases flywheel lightening is not recommended for all Duratec 30 engines.

Duratec Tuning Stages

Typical stage 1 mods often include: Panel air filters, Remaps/piggy back ECU, Sports exhaust manifold, Fast road camshaft, Drilled & smoothed airbox, Intake manifolds.

Typical stage 2 mods often include: fuel pump upgrades, Fast road cam, Sports catalyst & performance exhaust, high flow fuel injectors, Ported and polished head, induction kit.

Typical stage 3 mods often include: Competition cam, Crank and Piston upgrades to alter compression, Twin charging conversions, Adding or Upgrading forced induction (turbo/supercharger), Internal engine upgrades (head flowing porting/bigger valves), Engine balancing & blueprinting.

Camshaft Upgrades

We normally suggest performance camshafts as a main mod for petrol engines, and as a secondary mod for diesel engines to a remap. Performance camshafts can generally increase peak horsepower in most engines.

In terms of engine performance, camshaft changes may make a significant impact. Because the durations of the intake and exhaust valves are affected by the camshaft profile, substantial power improvements may be expected from these modifications.

Fast road camshafts usually increase the torque across the rev band, you may sacrifice a little low end bhp but your top end will improve.

Motorsport camshafts, increase the top end band but as a result the car will not idle smoothly and low end power nearly always suffers.

A Race camshaft is not great on the daily commute.

You should ideally optimize your power band to your cars usage so for a car used daily stick with a shorter duration Duratec 30 camshaft

Depending on the camshaft, some Duratec 30 engines react differently than others. You can't put a VVT cam in a non VVT engine, they are quite different but cam swaps within the duratec 30 engine range is common.

Because of manufacturing tolerances and quality variances, each engine and camshaft should be seen as unique. Check your engine on a rolling road to see whether this is the case and choose a cam duration to suit your needs, around 260-270 seems to work for most people in our experience.

The amount of torque you'll acquire is heavily influenced by factors such as the ecu map, fuel supply, fuel pump, and injectors.

On most engines, extending intake or exhaust valve durations and valve lift may improve performance, although this is not always the case.

Examine your alternatives, identify your alterations, and establish a power goal to help you avoid costly pitfalls.

ECU Mapping Improvements

ECU mapping allows a tuner to unlock the full potential of all the tuning mods you've fitted to your Duratec 30.

(Sometimes chip tuning the ECU is not an option, so an aftermarket ECU is the route to take, and most of these exceed the specs and performance of your factory ECU's but check it has knock protection and that you get it correctly setup.)

It will usually give around 30% more power on turbocharged vehicles and you can expect to see around 15% on NA (naturally aspirated) engines, but the end result usually vary depending on the tuning mods you've carried out and the condition of your engine.

Air Flow improvements

Tuning the Duratec 30 engine is all about getting more fuel and air into it.

headers enable gasoline to be introduced into a vehicle's engine cylinders after air has been removed from filters so a smooth short flow length optimises the intake duration.

It is possible to increase fuel mixing and power on the Duratec 30 by altering the Intake manifolds' design, especially on the budget non performance variants.

Only a few manufacturers provide well-optimized intake manifolds.

Adding a Duratec 30 big valve conversion, doing a bit of port work and head flowing will also boost bhp, and significantly will permit a better bhp increase on other parts.

Duratec Turbo upgrades

NA (naturally aspirated) engines need quite a lot of work when you add a turbo, so we have a separate guide to help you take into account the pros and cons of going this route on your Duratec 30

To maximise fuel efficiency, turbochargers increase the amount of air that enters the engine, allowing it to burn more gasoline at a higher rate.

Parts are more dependable and turbocharged engines use more solid components when they're in a vehicle.

Some engines are overspecified, while others are only equipped to handle the standard amount of power. Crank and piston quality must be upgraded to withstand the increased power.

When installing turbochargers on Duratec 30s, we see a lot of people invest a lot of money only to have the engine block throw a rod shortly after the installation is complete.

At low rpm, large turbos sometimes have no power at all, whereas tiny ones might spool up rapidly but lack the top-end torque.

Fortunately, we have variable vane turbos, which enable the vane angle to be adjusted based on speed to reduce latency and boost top-end horsepower and torque.

Twin scroll turbos divert the exhaust flow into two channels and push these at differently designed vanes in the turbo. They also boost the scavenging effect of the engine.

It is common that there's a restriction in the air flow sensor MAF/MAP on the Duratec 30 when considerably more air is being sucked into the engine.

Going up you'll find 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor limited performance at a much lower level.

Adding a supercharger or additional turbo will make large power gains, although harder to get working. We have this in depth look at twinchargers if you want to read more.

Duratec Fuelling Upgrades

You will need to ensure that the engine is not starved of fuel so need to pay attention to the fuelling when you start exceeding 20% of a power increase. Performance fuel pressure regulators can can provide a better throttle response.It makes sense to be generous with your injectors flow rate.

The accepted safe increase is to add 20% to the flow rate when specifying an injector, this allows for injector deterioration and affords a bit of spare capacity should the engine need more fuel.

We think this one is common sense, but you'll need to match your fuel injector to the type of fuel your car uses as well.

Performance Exhausts

If your exhaust is producing a flow restriction, you should consider upgrading it.

It is possible to get away with moderate power improvements with most factory exhausts, but once you start increasing the power you'll need a more efficient exhaust.

There is little doubt that sports exhausts will improve airflow through the engine, but be careful not to go overboard. As a general guideline, aim for a width of 1.5 to 2.5 inches.

If you're running a road-legal vehicle and you want to increase performance, you may do so by installing a sports catalyst, which is bigger and has a greater surface area than a standard catalyst. And because of its larger interior surface area and design, it will eliminate the constraint.

The alternative catless mod or catalyst removal should be regarded an off-road only modification, since removing a catalyst is prohibited in most areas and regions (and in others you can't even replace a functional catalyst).

Weak spots, Issues & problem areas on the Duratec 30

The Duratec 30 engines are generally reliable and solid as long as they are regularly serviced.

Carbon build up in the head, particularly around the valves which will reduce power, this is a larger issue on direct injection engines but should be looked out for on all engines. We have tips on carbon removal guide Avoid short journeys and use a good quality fuel.

Service time oil changes are highly recommended on the Duratec 30, especially when tuned and will help prolong the life of the engine.
