Nissan 370Z - the latest representative of the legendary Z-series, which won the love of car enthusiasts thanks to its aggressive design, rear-wheel drive and atmospheric V6 VQ37VHR volume 3.7 l. But even the factory 332 hp. (in the Nismo version - 350 hp) seem insufficient to many. Tuning this sports car allows you not only to increase power, but also to improve handling, braking performance, and also give the car a unique appearance.

In this article we will look at all areas of tuning - from simple chip tuning and installation of an exhaust system to complex modernization of the suspension and turbocharger. You will find out which modifications provide the maximum increase in power, and which are just a visual effect. We will also look at unique tuning features of the 370Z related to its design (for example, an overheating problem when boosting the engine) and give recommendations on choosing spare parts for different budgets.

1. Chip tuning and ECU firmware: the first step to increasing power

The most affordable and fastest way to increase power Nissan 370Z - this is flashing of the electronic control unit (ECU). Standard firmware is focused on environmental compliance and reliability, but not on maximum performance. After chip tuning you can get +20–30 hp without mechanical modifications.

Popular firmware options:

  • 🔹 Stock modification — optimization of the factory firmware (restrictions on speed are removed, ignition timing is adjusted). Suitable for daily use.
  • 🔹 Sports firmware (for example, from UpRev or EcuTek) — aggressive settings for the track, but require modifications to the fuel system.
  • 🔹 Custom tuning on the dyno - ideal option if other modifications are planned (turbine, intake, etc.).

The cost of chip tuning varies from 15,000 to 50,000 RUR depending on the complexity. However, it is important to remember: after the firmware, fuel consumption may increase (by 1–2 l/100 km), and will also require higher quality oil (for example, Motul 300V or Liqui Moly Leichtlauf).

⚠️ Attention: After chip tuning, be sure to check the operation catalysts And oxygen sensors. On some firmware they may give an error P0420 (low catalyst efficiency). The solution is to install decoys or remove the catalysts (but this is illegal for street use).

2. Intake and exhaust: how to improve engine breathing

Standard intake system 370Z has significant limitations, especially at high speeds. Replacing the air filter with nulevik (for example, from K&N or Injen) gives an increase +5–10 hp, but the main effect is improved throttle response. For serious tuning you will need:

  • 🔧 Cold intake (For example, Stillen or AAM Competition) - reduces the air temperature by 10–15°C, which increases the charge density.
  • 🔧 Large diameter throttle valve (65–70 mm instead of standard 60 mm).
  • 🔧 Intake manifold with polished channels (for example, from Tomei or JWT).

The exhaust system is no less important. Standard exhaust 370Z the engine chokes a lot, especially after 4000 rpm. Optimal options:

Exhaust typePower gainCost (₽)Features
Catalyst downpipe+10–15 hp30 000–50 000Improves sound but preserves catalysts
Catalyst-free downpipe+15–20 hp25 000–40 000Requires lambda probe decoys
Direct-flow muffler (for example, Borla or GReddy)+5–10 hp40 000–80 000Loud sound, possible problems with the traffic police
Full 4-2-1 exhaust (e.g. Tomei Expreme)+20–25 hp100 000–150 000Maximum performance, requires ECU tuning
⚠️ Attention: When installing a catalytic-free downpipe, be sure to turn off second lambda probe (bank 2, sensor 2) or install a blende. Otherwise, the ECU will constantly adjust the fuel mixture, which will lead to loss of power.
💡

If you are planning a turbocharger, immediately install an exhaust with a pipe diameter of at least 3" (76 mm). This will save money on future improvements.

3. Turbocharger: how to get 500+ hp. without engine replacement

Atmospheric VQ37VHR has great potential for boost, but for a serious increase in power (over 400 hp) will be required turbocharger or compressor. The most popular solutions:

  • 🚀 Sets from Stillen or GReddy - include turbine, intercooler, fuel injectors and firmware. Power increases to 450–500 hp.
  • 🚀 Compressor Vortech or ProCharger - gives a more linear response, but is more difficult to install.
  • 🚀 Self-assembly based on a turbine Garrett GTX3582R — for experienced tuners, allows you to squeeze 550+ hp.

However, the turbocharger has serious disadvantages:

  • ⚠️ Overheating — standard cooling system 370Z not designed for such loads. You will need to install an additional radiator and oil cooler.
  • ⚠️ Reliability - with power over 500 hp the risk of destruction of the pistons or crankshaft increases significantly. It is recommended to install a forged piston group (for example, from JE Pistons).
  • ⚠️ Fuel consumption — on the turbo version it increases to 20–25 l/100 km in the urban cycle.

The cost of a complete turbo kit starts from 300 000 ₽, and taking into account modifications (fuel system, cooling, transmission) can exceed 1 000 000 ₽. If your budget is limited, consider supercharger - it is cheaper and easier to install, but gives a smaller increase (up to 400–420 hp).

4. Suspension and Brakes: How to Make the 370Z Handle

Standard suspension Nissan 370Z It’s quite tough, but its weak points appear on the track: roll in corners and insufficient information content. To improve controllability use:

  • 🔧 Short stroke springs (For example, Tein S-Tech or H&R Sport) - reduce the center of gravity by 20–30 mm.
  • 🔧 Shock absorbers with adjustable stiffness (For example, KW V3 or Ohlin’s Road & Track).
  • 🔧 Anti-roll bars (from Hotchkis or SPC) - reduce roll in turns.
  • 🔧 Polyurethane bushings instead of rubber ones, they improve suspension response.

The braking system is no less important. Standard brakes 370Z (front discs 355 mm, rear 332 mm) quickly overheat on the track. Optimal upgrades:

ModificationEffectCost (₽)
Perforated discs DBA 5000 or Brembo GTBetter cooling, less fading50 000–80 000
Brake pads Ferodo DS2500 or Hawk HT-10High operating temperature (up to 800°C)20 000–35 000
Brake hoses GoodridgeStiffer pedal, no swell8 000–12 000
6-piston caliper Brembo (before)Improved braking, less disc wear150 000–200 000
⚠️ Attention: When installing low-profile rubber (for example, 245/40 R19) be sure to check wheel alignment. Incorrect angles will cause uneven tire wear and poor handling.
💡

Optimal tires for the track Michelin Pilot Sport Cup 2 or Toyo R888R. On the street they wear out quickly, but provide maximum grip.

5. Exterior tuning: how to make the 370Z unique

Appearance Nissan 370Z already aggressive, but many owners want to stand out. Popular destinations:

  • 🎨 Aerokit - complete sets from Nismo, Veilside or Rocket Bunny give the car a racing look. However, some whales (e.g. Pandem) require widening of the wheel arches.
  • 🎨 Spoilers and wings — improve downforce at high speeds. Popular models from AMS or Volk Racing.
  • 🎨 LED optics - replacing standard headlights with Morimoto or Spec-D improves lighting and appearance.
  • 🎨 Vintage style — some owners install retro-style bumpers 240Z or 280Z.

Painting and wrapping are also popular. For example, matte or satin film (3M or Avery Dennison) costs from 80 000 ₽, but allows you to quickly change color. For exclusivity use:

  • 🔥 Two-tone paint (for example, black hood + body in Deep Blue Pearl).
  • 🔥 Carbon fiber - hood, roof or mirrors made of carbon fiber (for example, from Seibon).
  • 🔥 Vinyl stickers - stripes, lettering or graphics (for example, in the style Nismo).

When choosing wheels, pay attention to departure (ET) and width. Optimal parameters for 370Z:

  • Front: 19×9.5 ET22 with rubber 245/40 R19.
  • Rear: 19×10.5 ET25 with rubber 275/35 R19.

Popular disc brands: Enkei PF05, Volk TE37, Work Emotion CR Kiwami.

What happens if you install rims that are too wide?

Discs that are too wide (e.g. 11J front) can hit the fender liners when the steering wheel is turned completely or on uneven surfaces. This also increases the load on the wheel bearings and reduces their service life. It is optimal not to exceed the width 10.5J behind and 9.5J front.

6. Interior tuning: comfort and sport at the same time

Salon 370Z designed in a sporty style, but many owners want to make it more exclusive or functional. Popular improvements:

  • 🛋️ Sports seats — Recaro SRD, Bride Zeta III or Sparco Pro 2000 provide better lateral support.
  • 🛋️ Steering wheel - replacement with Nismo or Momo with perforated leather.
  • 🛋️ Backlight - LED strips under the dashboard or in the feet (for example, Oracle Lighting).
  • 🛋️ Soundproofing — reduces noise from the exhaust and wheels (materials StP or Accent).

To improve multimedia install:

  • 🎵 Head unit with Apple CarPlay And Android Auto (For example, Pioneer AVH-Z5200BT).
  • 🎵 Acoustics - component system Focal or Morel + subwoofer JL Audio.
  • 🎵 Rear view camera - useful due to poor visibility 370Z.
⚠️ Attention: When installing low seats (for example, Bride Low Max) visibility may be impaired since a standard seat 370Z and so it is located quite low. Be sure to try the seat on before purchasing!

7. Transmission tuning: clutch, differential and gearbox

Standard clutch 370Z withstands up to 400 hp, but when forcing it has to be changed. Optimal options:

  • 🔩 Spec Stage 2+ - withstands 450–500 hp, suitable for outdoor use.
  • 🔩 Spec Stage 3+ - for the track, but tough in everyday use.
  • 🔩 Ceramic clutch Clutch Masters - durable, but expensive.

It is also worth paying attention to differential. Standard Viscous LSD in 370Z does not always effectively block the wheels. Popular upgrades:

  • 🔧 Limited slip differential Nismo — improves grip when exiting corners.
  • 🔧 1.5-way or 2-way LSD (for example, from Cusco or OS Giken) - for drifting or track.

Gearbox 370Z (6-speed manual or 7-speed automatic) reliable, but with power over 500 hp recommended:

  • 🔧 Install reinforced synchronizers (for example, from OS Giken).
  • 🔧 Replace gearbox oil pump to productive (for example, MFactory).
  • 🔧 Use gear oil with a high viscosity index (for example, Red Line MT-90).

8. Maintenance after tuning: what you need to know

After any tuning Nissan 370Z requires more careful maintenance. Highlights:

  • 🛠️ Oil - change every 5,000–7,000 km (for turbo versions - Motul 300V 10W-40 or Liqui Moly Race Tech GT1).
  • 🛠️ Spark plugs - use on high-powered engines NGK Iridium IX or Denso Iridium Power with less clearance (0.7–0.8 mm).
  • 🛠️ Fuel - for power above 400 hp required gasoline AI-98 or 100+ (For example, Gazpromneft G-Drive 100).
  • 🛠️ Diagnostics - once every 3–6 months check ECU errors (for example, using Consult III+ or Tactrix OpenPort).

Pay special attention cooling system. On forced 370Z Overheating problems often occur. Recommendations:

  • 🔥 Install aluminum radiator (For example, Koyorad or Mishimoto).
  • 🔥 Add oil cooler (For example, Setrab).
  • 🔥 Replace thermostat to a “colder” one (opens at 71°C instead of standard 82°C).
  • 🔥 Use antifreeze with a high boiling point (for example, Motul Inugel Optimal).
💡

After installing the turbine or compressor, be sure to check air/fuel ratio (AFR) on the dyno. Optimal values: 11.5:1–12.5:1 at full load.

FAQ: Frequently asked questions about tuning the Nissan 370Z

🔧 How much does it cost to fully tune a 370Z up to 500 hp?

The cost depends on the selected components, but on average:

  • Turbo kit: 300 000–500 000 ₽.
  • Fuel system (injectors, pump, regulator): 100 000–150 000 ₽.
  • Reinforced transmission (clutch, differential): 150 000–250 000 ₽.
  • Firmware and setup: 50 000–100 000 ₽.
  • Cooling (radiator, intercooler): 80 000–120 000 ₽.

Total: from 700,000 to 1,200,000 RUR excluding work. If you add suspension, brakes and external tuning, the budget may exceed 2 000 000 ₽.

⚡ Is it possible to install a turbine on an automatic transmission?

Technically yes, but automatic 370Z (7-speed JK41) not designed for high torque. At power above 450 hp you will need:

  • Install reinforced torque converter.
  • Update clutches and steel discs in a box.
  • Use special gear oil (For example, Amsoil Signature Series).

The cost of upgrading a machine starts from 200 000 ₽. To be more reliable, it is better to consider manual transmission or swap to CD009 (from Nissan GT-R).

🎨 Which aerokit is better for the 370Z: Nismo or Rocket Bunny?

The choice depends on the goals:

  • Nismo - factory style, good aerodynamics, but expensive (from 200 000 ₽). Suitable for street and light track use.
  • Rocket Bunny V2 — aggressive look, wide arches (requires tires 295/30 R19 rear). Price: from 150 000 ₽. Suitable for drift and show cars.
  • Veilside Fortune - the gold standard for the track, but difficult to install and expensive (from 300 000 ₽).

If you care downforce, pay attention to the wings from AMS or Volk Racing - they give until 50 kg downforce at speed 160 km/h.

🔧 What mistakes are most often made when tuning a 370Z?

Typical mistakes:

  1. Ignoring cooling - when boosting to 450+ hp A standard radiator won't do the job.
  2. Savings on the fuel system — standard nozzles (370 cc) will not pull the turbine.
  3. Incorrect firmware — the use of “universal” firmware without a dyno leads to detonation.
  4. Setting the suspension too hard — on broken roads this worsens handling.
  5. Ignoring transmission - standard clutch and differential will quickly fail.

Recommendation: before starting tuning, make a clear plan and consult with specialists who have experience working specifically with VQ37VHR.

🚗 Is it possible to make a drift car out of a 370Z?

Yes, Nissan 370Z — an excellent base for drifting thanks to rear-wheel drive and a powerful engine. To do this you will need:

  • Install differential with full lock (For example, Cusco 2-way LSD).
  • Replace suspension to an adjustable one (for example, BC Racing ER).
  • Install hydraulic handbrake (For example, OS Giken).
  • Use wide rear
