Let us review 2.8V6 24v tuning and point out the greatest upgrades.

When talking about the greatest parts for your 2.8V6 24v engine, we are going to concentrate on the upgrades that give the best value for money.

2.8V6 24v induction kits

Improving air intake on the 2.8V6 24v

You need fuel and air for an engine to work. If there is little supply of fuel then it will run lean, if there is little flow of air it runs rich sapping power . We'll pick up on fuelling later in this article but for now we shall look at air supply.

So Feeding more air into your 2.8V6 24v is the whole point to any performance tuning task.

You'll commonly see there is a limit in the air flow sensor AFM/MAF on the 2.8V6 24v when a lot more air is being pulled into the engine.

We see 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor was restricting bhp at a much lower level.

The intake plenum take the air from the intake filter and allow it to be pulled into the engine cylinders.

The size of bore and shape and rate of flow of the air Intake manifold can make a substantial effect on to fuel delivery on the 2.8V6 24v.

It's not uncommon that headers are ripe for performance upgrades, although some car makers provide well optimised headers.

Fitting big valve kits, doing some port work and head flowing will also boost bhp and torque, and importantly will give you a greater bhp and torque increase on other tuning parts.

2.8V6 24v performance cam tips.

Different 2.8V6 24v engines respond better to more or less aggressive camshaft durations check your engine on a rolling road.

The ecu map and injectors and fuel pump also have an effect on the power gains you'll hit.

Altering valve durations can alter the power band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations.

Significant air intake, and exhaust improvements on the 2.8V6 24v can be made from camshaft upgrades. Changing the camshaft profile alters the intake and exhaust durations on the engine and can dramatically change the bhp and power output.

NB: Fast road camshafts normally increase the bhp and torque through the rpm band, you may lose a little bottom end power but the high end rpm power will be lifted.

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

On a car used daily you need to optimize your power band to your usage of the car.

I'd be gobsmaked if you have found a 2.8V6 24v Motorsport and race camshaft is a pleasure to live with when driving in heavy traffic.

Stage 1, 2 and 3 mods for the 2.8V6 24v

Before we break the best tuning upgrades down into stages of tune, let's list the most effective tuning upgrades for you.

Tuning tips and articles Engine tuning Transmission tuning Care care Intake & exhaust mods Improve handling Forums
  1. Suspension Upgrades - always improve your cars handling
  2. Brake Upgrades - Even before adding power improve those brakes
  3. Intake - make sure the intake is not restricted, use filters and intake upgrades to improve this
  4. Exhaust - as with 3 ensure there is not restriction in the exhaust, cats are the usual bottleneck
  5. Tunes - remapping, piggyback ECU's and aftermarket ECU's can all make decent gains
  6. Fuelling - when you've increased power you'll need to match this with more fuel
  7. Turbo upgrades - Improving the intake with a large turbo and better flowing intercooler will be the biggest power gain you'll see (but one of the most complex).

This video guide to tuning cars is a great starting point to work from in your project.

Stage 1 2.8V6 24v parts:

Panel air filters, Sports exhaust manifold, Intake headers, Fast road camshaft, Drilled & smoothed airbox, Remaps/piggy back ECU.

Stage 2 2.8V6 24v parts:

induction kit, fuel pump upgrades, Ported and polished head, high flow fuel injectors, Fast road cam, Sports catalyst & performance exhaust.

Stage 3 2.8V6 24v parts:

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

Review your options and then buy your modifications and set yourself a power target to avoid wasting your time and money.

Remapping will help release the full potential of all the upgrades you've done to your 2.8V6 24v.

You will typically expect to see gains of approximately 20-30% more power on turbocharged vehicles and you can expect to see around 15% on NASP engines, but your mileage usually depend much on the upgrades you've done and the condition of your engine.

Turbo modifications on the 2.8V6 24v

To get a turbo working on a NASP engine there is a lot involved, from lowering compression ratio to improved fuel supply and mapping, so we have found a great guide to helpavoid the common pitfalls or end up with an unfinished project because you were not told what you were getting into by doing this on the 2.8V6 24v.

The more air you can get into an engine, the more fuel it can burn and uprating the induction with a turbocharger upgrade makes massive power gains.

If the engine is fitted with a turbo mods are going to net you a larger power gain and you will discover turbo engines already contain harder and stronger components.

However most engines will have power limits

It is important to find these restrictions and install stronger pistons, crank and engine components to survive the power.

There are many people spending a fortune on turbocharger upgrades on the 2.8V6 24v only to experience the car literally blow up soon after it's used on the roads.

Larger turbos commonly experience a bottom end lag, and small turbos spool up more quickly but won't have the top end torque gains.

Thanks to new tech the world of turbo units is always moving on and we are seeing variable vane turbo units, where the vane angle is altered according to speed to lower lag and increase top end torque.

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

Beefing up the air intake by adding a supercharger or additional turbo will help you achieve very large performance gains, although more complex to configure. We have this in depth look at twinchargers if you want to read more.

Tips about fuel supply on the 2.8V6 24v

When you raise the power you will need to pay attention to to the fuel delivery.

More power needs more fuel. It makes sense to be generous with your flow rate on the injectors.

As a rule of thumb add 15% capacity when specifying an injector, this takes into account injector deterioration and gives a little spare capacity should the engine need more fuel.

Don't forget that different fuel grades will usually require different settings, a high octane fuel will burn more efficiently than lower octane fuel for example. A car will trim fuel supply to keep within the ideal air fuel mix but at the extreme ends you may need to adjust your injector capacity, or the mapping or you'll get flat spots and potential lean or rich fuel issues..

Recommended 2.8V6 24v performance exhaust upgrades

The only time you should look to uprate your exhaust system with an upgraded one is if the existing exhaust is actually creating a flow problem.

On most factory exhausts you'll find the exhaust flow rate is fine even on modest power gains, but on a serious tuning project with a big boost in power you will certainly need to get a better flowing exhaust.

Sports exhausts increase the flow of air through the engine.

But if the exhaust pipe is too large, ie: it's over two and a half inches diameter, you will lose a great deal of your flow rate and end up lacking power and torque.

Usual exhaust restrictions are traced to the catalyst installed, so adding a faster flowing race alternative will help avoid this restriction.

Catalyst removal (NB:catalysts reduce harmful engine emissions) is illegal in most countries and regions.

Faults issues and things to look out for on the 2.8V6 24v

Like most engines an 2.8V6 24v, should have few issues if it gets properly serviced and looked after.

We cannot stress enough the need for oil changes with the correct grade of oil on the 2.8V6 24v, failure to do this will exacerbate engine wear, on a tuned 2.8V6 24v this is more important than ever and close attention should be paid to your maintenance schedule.
