Tuning Feature: Nissan BR06DET Modified

"Comprehensive guide to performance parts and tuning the Nissan BR06DET engine!"

We often are getting emails asking about the greatest BR06DET mods that work. So let us look into Nissan BR06DET tuning mods and outline the best mods that work on this great engine and point out some problems along the way.

This pages aim is review and look at BR06DET tuning and report on the premier modifications for your car. Nissan BR06DET are popular tuning projects and with the ultimate parts like remapping, turbo kits and camshafts you will increase the drivers fun of your car.

When talking about the optimum parts for your BR06DET engine, we are going to concentrate on the ones that give the best value for money.

Significant power increases can be made on engines, and the BR06DET is no exception, by means of cam upgrades. Altering the cam profile alters the intake and exhaust durations on the engine and can dramatically change the bhp and power output.

NB: Fast road cams normally boost the bhp across the rev range, you may sacrifice a little bottom end bhp but high end rpm power will improve.

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

In a typical daily driver one, ideally, should ideally to optimize your bhp range to your cars usage.

I'd be amazed if you have found a BR06DET Race camshaft is a pleasure to live with when driving around busy urban areas.

Different BR06DET engines respond better to extreme cam durations check your engine on a rolling road.

The ECU mapping and injectors and fuel pump also will make differences on the torque gains you'll hit.

Altering valve durations can alter the torque 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.

BR06DET Tuning Stages

Stage 1 BR06DET modifications: Sports exhaust manifold, Panel air filters, Fast road camshaft, Intake headers, Drilled & smoothed airbox, Remaps/piggy back ECU.

Stage 2 BR06DET modifications: Ported and polished head, high flow fuel injectors, Fast road cam, induction kit, Sports catalyst & performance exhaust, fuel pump upgrades.

Stage 3 BR06DET modifications: Competition cam, Crank and Piston upgrades to alter compression, Twin charging conversions, Engine balancing & blueprinting, Internal engine upgrades (head flowing porting/bigger valves), Adding or Upgrading forced induction (turbo/supercharger).

ECU flashing allows a tuner to release the full potential of all the tuning mods you've done to your BR06DET.

It will usually give around 30% more power on turbocharged vehicles and you can expect to see around 15% on NASP engines, but your mileage often rely on the tuning mods you've fitted and the condition of your engine.

Forcing air into your BR06DET is vital to any car tuning task.

The intake plenum flow the air from the filter and allow it to be pulled into the engine and mixed with fuel.

Shape and rate of flow of the Intake headers can make a substantial change to fuel atomisation on the BR06DET.

On popular production engines plenum chambers are improved through aftermarket parts, although a few manufacturers provide decently flowing plenum chambers.

Fitting big valve kits, doing a bit of 3 or 5 angle valve jobs and porting and head flowing will also raise bhp, and importantly will afford you an improved bhp increase on other upgrades.

Turbo upgrades for the BR06DET

NASP 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 BR06DET

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

When an engine has a turbocharger modifications are more reliable and turbocharged engines use many forged and stronger components.

However every engines have weakspots

See where you'll find these limitations and upgrade to higher quality components to handle the power.

We see many drivers spending a fortune on turbo upgrades on the BR06DET only to suffer the indignity of watching the BR06DET literally blow up just after it's finished.

Bigger capacity turbo units will usually suffer no power at low rpm, and small turbo units spool up really quickly but do not have the high rpm engines power gains.

Thanks to new tech the market of turbo units is always evolving and we commonly find variable vane turbo units, where the vane profile is altered according to speed to lower lag and increase top end bhp.

Twin scroll turbo units divert the exhaust gases into two channels and feed these at differently profiled vanes in the turbocharger. They also increase the scavenging effect of the engine.

It is common that there is a limit in the air flow sensor AFM/MAP on the BR06DET when loads more air is being drawn into the engine.

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

Adding a supercharger or additional turbo will make large torque gains, although more challenging to configure. We have this article covering twinchargers if you want to read more.

Uprating BR06DET fuel injectors

You will need to ensure that the engine is not starved of fuel so should pay attention to the fuelling when you start exceeding 20% of a torque increase.It makes sense to be generous with your injector capacity.

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

Best BR06DET performance exhausts

Only look to boost your exhaust if your current exhaust is actually creating a restriction.

On most factory exhausts you should find that the flow rate is still fine even on modest power gains, but when you start pushing up the power levels you will need to get a better flowing exhaust.

Please dont run with the biggest exhaust you can buy this will slow the exhaust rate - the best exhausts for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Typically exhaust restrictions can be located in the catalyst installed, so adding a higher flowing high performance alternative will help avoid this restriction.

Problems and issues to look out for on the BR06DET

The BR06DET engines, if regularly serviced and maintained, are generally very reliable and have few issues. {But if neglected they can cost a small fortune|When neglected they get very expensive to run|They can however be quite expensive if neglected| }

Regular oil changes are vital on the BR06DET, particularly when the engine has been modified and is putting down more power than the manufacturer intended.
