Tuning Nissan Murano Z51: how to turn a crossover into a masterpiece without mistakes

Crossover Nissan Murano Z51 (2015–2023) is a stylish and comfortable car, but even it is not without potential for improvement. Owners are often faced with the desire to add power, improve handling, or stand out on the road. However, tuning this generation Murano has its own nuances: from the features 3.5 liter V6 VQ35DE to electronics with system NissanConnect, which can be capricious after interventions.

In this article we will look at proven tuning methods - from software to mechanical ones - that actually work on Z51, and also warn about common errors. For example, why installing a turbine on a VQ35DE without preparing the cylinder block reduces engine life by 2–3 times, or how incorrect selection of springs leads to failure of shock absorbers Kayaba already after 20 thousand km. Ready to turn your Murano into a unique car? Let's start with the most important thing - the engine.

Chip tuning and software improvements: what really gives?

The first thing most owners start with is ECU flashing. Stock firmware Nissan Murano Z51 limits power to 260 hp, but engine potential VQ35DE allows you to remove up to 300–320 hp without mechanical modifications. However, there are pitfalls here:

• 🔧 Original ECU from Hitachi blocks uncertified firmware - will require bypass through Bench Flash or installing an additional module (for example, Piggyback from Hondata).
• ⚡ Increase in power by 15–20% is achieved by optimizing ignition timing and fuel maps, but this increases the load on the transmission.
• ⚠️ Risk of overheating: after chip tuning, the oil temperature can rise to 110°C in the urban cycle, the installation of an additional radiator is required.

Among the proven solutions:

• 📌 ECUtek — allows you to fine-tune the firmware for a specific fuel (for example, for AI-98 or E85).
• 📌 Cobb Accessport — convenient for self-adjusting parameters, but requires regular updates.
• 📌 OpenECU - a budget option, but only works with a modified ECU.

⚠️ Attention: After flashing, be sure to reset the adaptations via Nissan Consult III or Launch X431. Otherwise, the ECU will “learn” using the old parameters, which will lead to jerks during acceleration.

Mechanical engine tuning: turbine, compressor or aspirated?

If chip tuning is not enough, owners Murano Z51 Mechanical modifications are being considered. The main thing here is not to overdo it: the engine VQ35DE It is not designed for extreme loads, and its service life is reduced after boost. Let's consider three main ways:

Revision type	Power gain	Cost (RUB)	Difficulty of installation	Risks
Turbokit (For example, GReddy)	+80–120 hp	450 000–700 000	High (requires welding)	Overheating, oil starvation, turbine output
Compressor (Vortech or Eaton)	+50–70 hp	350 000–500 000	Medium (needs new pulley)	Increased wear on the timing belt
Aspirated (boring, inlet, outlet)	+20–40 hp	150 000–300 000	Low	Minimum (if configured correctly)

The most balanced option is compressor. It provides an increase in power without putting critical loads on the engine, and its installation does not require intervention in the exhaust system. A turbo kit is justified only with an integrated approach: strengthening the cylinder block, replacing pistons with forged ones (for example, from JE Pistons) and modernization of the cooling system.

For atmospheric modifications we recommend:

• 🔥 Cold intake (Injen or K&N) - adds 5–8 hp and improves the sound.
• 🔥 Direct-flow release (For example, Borla or MagnaFlow) - adds 10–15 hp, but may cause an error P0420 (low catalyst efficiency).
• 🔥 Throttle valve increased diameter (for example, from Nissan 370Z) - improves responsiveness at high speeds.

What happens if you install a turbine without preparation?

Without strengthening the cylinder block and upgrading the lubrication system, the turbine on the VQ35DE will lead to “oil starvation” after 5–10 thousand km. Typical consequences: wear of the crankshaft liners, scuffing of the cylinders and major engine repairs costing 300+ thousand rubles.

Suspension tuning: how not to spoil comfort?

Nissan Murano Z51 initially set to soft, but many owners want to make it sportier. The main mistake is installing stiff springs or short-stroke shock absorbers, which turn the crossover into a “cart”. The best option is adjustable suspension or kits from trusted brands.

The best solutions for suspension tuning:

• 🚗 BC Racing BR - shock absorbers with adjustable stiffness allow you to lower the car to 30–50 mm without loss of comfort.
• 🚗 Tein Street Advance Z — a ready-made set of springs and shock absorbers, designed for everyday use.
• 🚗 H&R Sport Springs - reduce ground clearance by 25–35 mm, but require replacing the racks with more rigid ones.

⚠️ Attention: When installing springs with a stiffness greater than 6 kg/mm Be sure to check the condition of the rear beam silent blocks. On Murano Z51 they fail after 15–20 thousand km under increased loads.

To improve handling we also recommend:

• 🔧 Anti-roll bars from Hotchkis - reduce roll when cornering.
• 🔧 Polyurethane bushings instead of rubber ones, they increase the accuracy of steering reactions.
• 🔧 Reinforced levers from SPC - necessary when the clearance decreases by more than 40 mm.

Braking system: when standard brakes are not enough

Stock brakes Murano Z51 (front discs 320 mm, rear 302 mm) cope with everyday loads, but after chip tuning or installing a turbine they have to be upgraded. Main problems:

• 🔥 Overheating — during intensive braking, the temperature of the discs exceeds 500°C, which leads to deformation.
• 🔥 Lack of efficiency — standard calipers are not designed for increased weight (for example, when installing armor).

Upgrade solutions:

Component	Recommended Brand	Notes
Front discs	Brembo or EBC (355 mm)	Requires adapters for calipers
Calipers	Brembo 4-pot or Wilwood	Compatible with original brake hoses
Pads	Ferodo DS2500 or Hawk HPS	Suitable for everyday use
Brake hoses	Goodridge or Hel	Eliminates pedal "wobbiness"

When installing larger diameter brakes, do not forget about wheel spacers - otherwise the discs will touch the spokes. Optimal offset (ET) for Murano Z51 after brake upgrade: ET35–ET40.

💡

After replacing brake discs and pads, be sure to carry out the procedure bedding-in: 10–15 smooth braking from a speed of 80–100 km/h to 30–40 km/h. This will remove micro-irregularities and increase the system resource.

External tuning: how not to go too far with style?

Nissan Murano Z51 already looks aggressive thanks to the signature grille "V-Motion", but many owners want to make it even more memorable. The main rule is maintain harmony: too massive body kits or poor painting can ruin the appearance.

Popular destinations:

• 🎨 Vinyl wrap - matte or glossy film (for example, 3M 1080) costs from 50,000 rub. and allows you to quickly change your image.
• 🎨 Body kits - front splitter from Stillen or rear diffuser from Nismo add sportiness.
• 🎨 Optics — LED headlights (Morimoto) or tinted rear lights (Lamin-X).
• 🎨 Wheels - disks 20–22" from Vossen or Rotiform with rubber 255/40 R20.

Beware of cheap Chinese body kits - they often do not fit well with the body and begin to “play” at higher speeds 120 km/h. It is better to choose original parts from Nismo or quality replicas from Duran.

⚠️ Attention: When installing disks with a diameter 22" Be sure to check the gap between the tire and the arch when turning the steering wheel completely. On Murano Z51 With the factory suspension, friction often occurs.

Interior tuning: comfort and technology

Salon Murano Z51 already equipped with leather trim and multimedia NissanConnect, but it can be made even more convenient and modern. Main directions:

• 🛋️ Multimedia — replacement of the standard system with Android Auto (For example, Pumpkin or Joying) with support Apple CarPlay.
• 🛋️ Backlight — LED strips under the dashboard or in the door cards (color RGB controlled via app).
• 🛋️ Steering wheel — installation of a sports steering wheel from Nismo or Momo heated.
• 🛋️ Sound — audio system upgrade: subwoofer JL Audio + amplifier Alpine.

When replacing multimedia, it is important to keep the standard functions working: cameras 360°, climate control and steering buttons. To do this, use adapters from Maestro RR or iDatalink.

💡

The most common mistake when tuning an interior is ignoring the weight of additional equipment. For example, installing a subwoofer in the trunk without a reinforced floor can result in vibrations at speeds above 100 km/h.

Typical tuning mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when finalizing Nissan Murano Z51. Here are the most common:

1. Ignoring ECU adaptations after chip tuning - leads to unstable engine operation.
2. Installing springs that are too stiff — destroys silent blocks and impairs handling on uneven roads.
3. Saving on brakes - cheap pads or discs can crack during the first intense braking.
4. Incorrect vinyl wrapping — bubbles and peeling appear after 1–2 months due to poor quality shrinkage.
5. Using universal firmware - instead of individual customization for a specific car.

To avoid problems, follow two rules:

1. Before any modifications, carry out diagnostics (for example, via Launch X431 or Nissan Consult).
2. Use certified parts from trusted brands (for example, Brembo, ECUtek, Tein).

What to do if the Check Engine light comes on after chip tuning?

First check the error code using a scanner. Most often this P0300 (misfire) or P0171 (lean mixture). Solution: Reset the ECU adaptations and check the fuel injectors. If the error remains, the firmware needs to be adjusted.

FAQ: Answers to frequently asked questions

Is it possible to install a turbo on a Murano Z51 without strengthening the engine?

Technically possible, but highly not recommended. Engine VQ35DE is not designed for increased pressure, and without strengthening the cylinder block, forged pistons and upgrading the lubrication system, the turbine will reduce the engine life to 30–50 thousand km.

Which chip tuning is better: via OBD or Bench Flash?

Bench Flash (flashing on the table) is more reliable, as it allows you to fully control the process and avoid recording errors. Chip tuning via OBD-II more convenient, but suitable only for minor modifications (for example, removing the speed limit).

What wheels can be installed on the Murano Z51 without modifications?

Maximum diameter without modifications - 20" with departure ET40 and width 8.5J. For 21–22" you will need to roll out the arches or install spacers. Example of compatible models: Vossen CV3 or Rotiform LAS-R.

Is it worth installing air suspension on the Murano Z51?

Air suspension (Air Lift or Bag Riders) is possible, but requires serious modifications: strengthening the mounting points, replacing the racks with specialized ones and setting up the control system. The cost of the kit starts from 250,000 rub., plus monthly maintenance (check for leaks, compressor replacement).

What is the service life of the VQ35DE engine after chip tuning?

With correct settings (without detonation and overheating), the service life is reduced by 10–15%. For example, if before tuning the engine was running 300 thousand km, then after - 250–270 thousand km. It is critical to use quality oil (Motul 5W-40 or Liqui Moly 5W-30) and monitor the cooling system.
