How to modify and upgrade the Nissan CR10DE

"Comprehensive guide to tuning the Nissan CR10DE engine!"

Our friends at TorqueCars are regularly getting emails requesting info on how to improve the CR10DE from people wanting to know what are the things tuners recommend when it comes to CR10DE upgrades. So let us look into Nissan CR10DE tuning mods and outline the best mods that work on this great engine and point out some frequent tuning mistakes along the way.

We shall consider CR10DE tuning and show the best modifications. Nissan CR10DE are awesome to work on and with the optimum uprated upgrades like remaps, turbo kits and camshafts you will substantially increase your driving enjoyment.

Just because particular tuning parts are appear in lots of CR10DE projects it doesn't mean it is good, instead we will concentrate on the best tuning parts that will give your CR10DE the best value for money to power increase.

Without us subscribing to the popular mentality of 'if it's shiny and makes more noise it must be good' you seem to get in many tuning magazines and on car forums'.

CR10DE induction kits

Improving air intake on the CR10DE

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

So the fundamental goal to any performance tuning job to pull air into your CR10DE but this has a knock on effect with the air flow sensor.

You'll commonly see there's a restriction in the air flow sensor MAF/MAP on the CR10DE when a lot more air is being drawn into the engine.

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

Intake headers transmit the air during the suck phase from the filter and allow it to be drawn into the engine cylinders.

Design and rate of flow of the air Intake manifold can make a big effect on to fuel atomisation and engine efficiency on the CR10DE.

Many mass produced engine headers are begging for motorsport parts, although a few OEM provide reasonably well designed headers.

Increasing the CR10DE valve size, doing some port matching and head flowing will also improve performance, and as an added benefit will permit raising the performance increase on other tuning parts.

CR10DE performance cam tips.

Different CR10DE engines respond better to different cam durations than others.

The map and fuelling also will say much on the bhp gains you'll make.

A longer valve duration can alter the bhp 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.

Altering your CR10DE cam will make a dramatic difference to the engine power band. Choosing a higher performance cam profile raises the power band accordingly.

NB: Fast road cams normally boost the bhp and torque throughout the rpm band, you could sacrifice a little bottom end power but your high end rpm power will be better.

Race 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.

A Motorsport and race cam makes it harder when in heavy traffic.

You should ideally match your engines power to your usage of the car so for a car driven daily stick with a mild fast road CR10DE cam

Stage 1, 2 and 3 mods for the CR10DE

Stage 1 CR10DE parts:

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

Stage 2 CR10DE parts:

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

Stage 3 CR10DE parts:

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

Plan your options and then find your upgrades and set yourself a power target to avoid expensive mistakes.

ECU flashing allows a tuner to fully realize the full potential of all the upgrades you've done to your CR10DE.

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 the outcome will depend much on the upgrades you've done and the condition of your engine.

Turbo modifications on the CR10DE

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 CR10DE.

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

If your motor has forced induction tuning parts are relatively easy and you will discover turbocharged engines use more solid components.

However you'll find engines have weakspots

We recommend you find these limits and install higher quality crank and pistons to survive the power.

It's not unheard of mechanics spending a a stack of money on turbo charger upgrades on the CR10DE only to have the CR10DE literally blow up on it's first outing after it's used in anger.

Large turbo chargers will usually experience a bottom end lag, and low capacity turbo chargers spool up really quickly but do not have the top end torque gains.

We are pleased that the range of turbos is always moving on and we commonly find variable vane turbos, permitting the vane angle is altered according to speed to lower lag and increase top end performance.

Twin scroll turbos divert the exhaust gases into a couple of channels and direct these at differently angled 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 bhp and torque gains, although more complex to configure. We have this feature on twinchargers if you want to read more.

Tips about fuel supply on the CR10DE

You will need to ensure that the engine is not starved of fuel so will have to uprate the fuelling when you start going beyond 20% of a bhp hike. Experienced tuners recommend to be generous with your injector capacity.

As a rule of thumb add another 15% when buying an injector, helps cope with injector deterioration and gives some 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 CR10DE performance exhaust upgrades

We'd only recommend you look to boost your exhaust system with an upgraded one is if the current exhaust is actually creating a restriction in flow.

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 can usually air flow from the engine but avoid an exhaust that is too big or you could will reduce the flow rate. Stick to one and a half to two and half inches as a rule of thumb.

Usual exhaust restrictions can be located the filters installed, so adding a faster flowing race alternative will help avoid this restriction.

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

Faults issues and things to look out for on the CR10DE

Like most engines an CR10DE, 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 CR10DE, failure to do this will exacerbate engine wear, on a tuned CR10DE this is more important than ever and close attention should be paid to your maintenance schedule.
