Improving the handling for people often first priority in your RAV4 tuning project.

We would go to a maximum drop of 35mm on most models. You risk ruining the stance and practicality of the car if you go lower than this.

Our aim in RAV4 engine tuning should be to increase peak power and Torque at the top end.

With our pointers your RAV4 can become an awesome performer and yet still reliable daily run around.

The best power gains come from larger engine sizes. The more you start with the bigger the return on investment so engine swaps are good value mods for small engined cars.

Can the RAV4 be tuned?

Yes and we are pleased to report that in most areas there is a growing number of aftermarket parts for this.

If you have a hybrid RAV4, modifications can be a bit more complex. It's crucial to ensure that any changes are compatible with the hybrid system and don’t interfere with its operation.

Can the RAV4 be remapped?

Most recent models can be easily mapped but early models will require an aftermarket ECU or piggyback ECU to change the mapping parameters.

This list of the stages and performance modifications are usually installed by our members, decide how far you want to push your car before you begin.

Getting the right uprated upgrade kits for your planned usage of the car is a time and money saver. Stage 3 competition upgrades just won't work well on the road difficult in stop start traffic.

Best Mods for your RAV4

  1. Engine Tunes - engine tuning/remapping provides the most power in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives on older RAV4's.
  2. Fast road cams are one of the most significant mechanical changes for pre VVT engines, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Suspension Upgrades - improving the handling of the RAV4 really improves your enjoyment of this well designed chassis.

RAV4 Tuning stages

Typical stage 1 mods often include:
Alloy wheels,Suspension upgrade (drop 30-40mm),Sports exhaust,Lighter flywheel,Panel air filter,Remap.

Typical stage 2 mods often include:
Fast road cam,Power clutch,Fuel injector & fuel pump upgrades,Ported and polished head,.

Typical stage 3 mods often include:
Competition cam,Adding or upgrading forced induction (turbo/supercharger),Internal engine upgrades (pistons/head/valves),Sports gearbox,Engine balancing.

Peak power is nice in motorsport but for a daily driven car you need a long torque band and perhaps extending the rev range.

The point of our tips is to give a little insight into the world of modding mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your tuning project, the best sport modifications and all aspects of modding cars.

RAV4 Suspension Mods

Personally I feel the weakest area on the Rav 4 is the suspension, and I would argue it has been setup for comfort over performance on most models over the years.

Whilst engine mods on the RAV 4 will not make huge power unless you invest heavily you can do much to improve cornering and handling with a relatively cheap upgrade.

Suspension Modifications & Upgrades for the RAV4

Suspension geometry dictates how a vehicle handles, and hence improving it is an excellent method to boost performance.

Lowering Springs

Reduce the height of your vehicle to enhance handling. There are various brands of lowering springs available, but we would strongly recommend you stick with a quality kit, and we prefer coilovers that are adjustable wherever they are available.

Suspension Kits for the Toyota RAV4

Investing in a suspension package is another cost-effective method of achieving a premium appearance and performance.

The following brands crop up regularly and it is fair to say you get more adjustability and control on the more expensive options, but for many a cheaper generic fit and drive kit will be sufficient.

  • BC Racing
  • H&R Sprince
  • Spax
  • Eibach Pro
  • V Maxx

Coilover Kits for the Toyota RAV4

Coilover systems often, use rubber top mounts on both the front and rear ends to offer a comfortable ride at any speed and allow you to adjust the ride height and spring characteristics.

They are intended to efficiently absorb heavy impacts, providing drivers with a very pleasant ride.
Therefore, if you're seeking for a comparable sensation, consider investing in one of the high-end coilover kits.

Shock Absorbers for the RAV4

As its name implies, shock absorbers are designed to absorb shocks and hence provide a more pleasant ride.

RAV4 Performance Camshafts

Understanding Camshaft Upgrades in the Context of VVT

In the realm of tuning, a fast road camshaft is often hailed as one of the most impactful single-part modifications for naturally aspirated (NASP) engines. However, with the advent of Variable Valve Timing (VVT) in newer Toyota RAV4 models, the dynamics of camshaft upgrades have evolved.

Performance Camshafts and VVT Systems

Performance camshafts are designed to enhance power, particularly at higher RPMs, and are generally more beneficial for gasoline engines and on engines without VVT.

While traditional camshaft upgrades can increase top-end power, the integration of VVT in modern RAV4 engines adds a layer of complexity. VVT systems dynamically adjust valve timing, already optimizing engine performance across various RPM ranges.

On Pre VVT engines a fast road camshaft proves to be one of the best NASP power modifications you can do with a single part fitted to your engine.

Cam Profile and Engine Power The cam profile plays a crucial role in engine power output. Modifications to the cam can lead to significant power improvements, as they alter the intake and exhaust durations.

However, with VVT engines like those in newer RAV4s, the benefits of aftermarket camshafts are not as straightforward. VVT systems already adjust these durations for optimal performance.

Fast road camshafts typically enhance performance over the entire rev range, but this might come at the cost of some bottom-end power while improving the top-end.

Conversely, race camshafts focus on high-end power, often resulting in a rough idle and reduced low-end performance – not ideal for everyday driving.

For a daily-driven vehicle, it's important to align horsepower modifications with your typical driving needs. In a vehicle like the RAV4, a motorsport cam is likely to be less enjoyable in heavy traffic, as aggressive cam profiles can lead to lumpy idles and stalling issues in stop-and-go conditions.

This is particularly relevant for VVT-equipped engines, where altering the cam profile may disrupt the finely tuned balance achieved by the VVT system.

Each engine responds differently to camshaft installations, influenced by factors like head design and airflow characteristics. In VVT-equipped RAV4 engines, these responses can be more complex due to the existing optimization provided by the VVT system.

Enhancements to the RAV4's airflow

The intake and exhaust flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car hard to drive in traffic.

Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty.

Using higher octane petrol is another option if you find you are suffering from detonation or premature ignition on your Toyota project after fitting other upgrades.

Uprated injectors will enable you to supply sufficient fuel to the engine. If have increased your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

RAV4 Intake and Exhaust Tuning.

Breathing mods or modifications to your vehicle's air intake system, are often the first step in enhancing engine performance.

For your Toyota RAV4, these modifications are crucial, especially after extensive tuning, to ensure that the engine can take in as much air as needed without any restrictions.

Understanding Induction Kits While we generally do not recommend induction kits for lightly modified vehicles, they can be beneficial in certain scenarios.

If you've extensively tuned your car and the standard air intake has become a bottleneck, an induction kit might be the solution.

These kits are particularly effective on turbocharged engines and larger engines, provided they are equipped with a suitable cold air feed or air box.

Recommended Air Filter Upgrades For most RAV4 engines, replacing the factory air filter with a high-quality sports panel air filter, preferably made from cotton, is a wise choice.

Brands like Jetex and Green Powerflow offer budget-friendly induction kits that can significantly improve air flow while maintaining affordability.

The Role of Air Intake Manifolds The air intake manifold plays a pivotal role in engine performance. It transports air from the air filter to the engine cylinders during the intake phase.

Upgrading this component can lead to better air flow, ensuring that your engine breathes more efficiently.

Benefits of Air Intake System Upgrades Upgrading the air intake system of your RAV4 is essential for several reasons:

  • Increased Air Intake: An enhanced air intake system allows your vehicle to 'gulp' more air compared to the stock setup.
  • Efficient Fuel Mixing: With improved airflow, your RAV4's engine can mix fuel and air more efficiently, leading to better combustion.
  • Boosted Power and Torque: As a result of the more effective combustion process, you can expect an increase in both power and torque outputs.

Final Thoughts on RAV4 Air Intake Upgrades When considering upgrades to your RAV4's air intake system, it's important to match these modifications with your vehicle's level of tuning.

An induction kit, like those from Jetex or Green Powerflow, can be a great addition for heavily modified engines.

However, for less extensive modifications, a high-quality sports air filter can provide a noticeable improvement in air flow and engine performance.

Upgrading the air intake system is a foundational step in car tuning, setting the stage for further performance enhancements.

With the right modifications, your RAV4 can achieve greater efficiency, power, and overall driving satisfaction.

RAV4 Performance Panel Filters

Another method of increasing airflow to the engine is to use performance air filters. These components have been particularly engineered to be less obstructive. As a result, they allow for more airflow.

Improving Intakes Further

On the RAV4, doing large valve conversions, porting, and head flowing will also improve bhp, and as an extra advantage, will let you to enhance the bhp increase from other modifications.

Newer engines are actually not badly designed, but early engines left much to be desired when it comes to airflow.


Toyota Rav 4 Exhaust Mods

Sports exhausts play a crucial role in balancing the flow of air through an engine, which is essential for optimal performance. They are designed to enhance the efficiency of exhaust gas expulsion, thereby improving the engine's breathing capability. This improvement in airflow can lead to noticeable gains in both power and torque.

The Importance of Choosing the Right Size However, it's vital to select the appropriate size for your sports exhaust. If the exhaust is too large, particularly over 2.5 inches in bore diameter on smaller sized engines, it can counterintuitively reduce the flow rate.

This decrease in flow rate can lead to a loss of power and torque, undermining the exhaust upgrade's intended benefits. The key is to find a balance that allows for efficient exhaust gas expulsion without compromising the flow dynamics.

Legalities of DPF and Catalyst Removal When upgrading exhaust systems, it's also important to consider the legal aspects, particularly concerning the Diesel Particulate Filter (DPF) and catalytic converter.

  • DPF Removal: The DPF is an essential component in diesel vehicles, designed to reduce emissions by capturing soot and particulate matter. Removing the DPF is illegal in many regions, as it directly contravenes emissions regulations. Vehicles without a DPF will fail emissions tests and can attract hefty fines and legal consequences.
  • Catalytic Converter Removal: Similarly, the catalytic converter is a critical component in reducing harmful exhaust emissions. Removing or tampering with the catalytic converter is illegal in many places due to environmental protection laws. Vehicles must maintain their catalytic converters to remain compliant with emissions standards.

Compliance and Performance

For those looking to upgrade their exhaust systems, it's essential to ensure that any modifications comply with local emissions regulations. While sports exhausts can significantly improve performance, they should be chosen and installed with an understanding of both the vehicle's needs and legal requirements. Upgrades should enhance the vehicle's performance without compromising its environmental compliance.

Clutch Upgrades

When tuning a Toyota RAV4, especially if you're increasing its power and torque, upgrading the clutch and flywheel can be a wise decision. These components are critical in handling the additional stress that comes with enhanced performance. A good "fast road" spec upgraded clutch will help to keep that power going where it should.

Never cut corners or assume a standard clutch to cope. Remaps offer significant power gains on all turbo charged cars. On NA (naturally aspirated) engines the benefits are doubtful.

The clutch connects the engine to the drivetrain. With increased power from engine tuning, the stock clutch might not be able to efficiently transfer this power without slipping. An upgraded clutch can handle higher torque, ensuring smooth and reliable power delivery.

Options include heavier-duty clutches or performance clutches designed for tuned vehicles. These clutches have better heat resistance and provide a more aggressive engagement, suitable for high-performance driving.

Flywheel Modifications

Improving Response with a Lightweight Flywheel: The flywheel's mass impacts how quickly the engine can change speeds. Replacing the standard flywheel with a lightweight version can significantly improve the engine's responsiveness.

A lighter flywheel reduces rotational inertia, allowing the engine to rev up and down faster, which is particularly beneficial in performance driving scenarios.

Considerations: It's important to note that while a lightweight flywheel offers quicker engine response, it might also lead to a less smooth idle and can affect low-speed drivability.

This is something to consider if the RAV4 is used as a daily driver.

However a tuned/remapped ECU on a NA (naturally aspirated) engine will help unleash the potential if you have done a lot of mods.

We've also come across some owners playing with twin charging conversions and making some impressively high power figures.

The most phenomenal power gains for NA (naturally aspirated) engines usually involve the addition of forced induction. Turbos are generally harder to add than a supercharger. It is difficult to map fuelling with a turbo as the boost comes on exponentially with engine speed.

It is easier to map a supercharger because the boost is proportional to engine speed on a linear curve. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

RAV4 Alloy Wheel Upgrades.

Alloy wheels will help the brake cooling and are usually less heavy than the steel ones.

We'd like to point out although they can look cool on the RAV4 big alloy wheels will actually decrease your performance. The larger you go the lower your acceleration will be - this to the change in your effective final drive ratio.

For this reason we would advise sticking to a maximum wheel size of 18 or 19 inches, although we know some of our members have gone larger than this with no problems with low profile tyres but this just doesn't seem right on the RAV4.
