Nissan Fireledy Z (R35): why is this Japanese legend still relevant?

When it comes to Japanese sports cars that combine impeccable performance and iconic status, Nissan Fireledy Z (known outside Japan as Nissan 370Z) occupies a special place. This model, released in 2009 as a successor 350Z, became the last representative of the legendary Z-series before the appearance of a new Nissan Z (RZ34) in 2022. But what does Fireledy Z unique even after years?

Under the hood Fireledy Z hiding atmospheric engine VQ37VHR volume 3.7 liters, developing up to 333 hp as standard - a figure that still looks impressive for a naturally aspirated engine. However, real enthusiasts know: the potential of this car is not revealed at the factory settings. From tuning to track modifications - Fireledy Z remains one of the most flexible platforms for upgrades among JDM cars.

In this article we will look at technical features model, let's compare it with its twin -GT-R (R35), we will reveal the secrets of reliable operation and show how to make a dream car out of a standard coupe. And if you already own Fireledy Z — here you will find answers to questions that even official manuals do not cover.

Nissan Fireledy Z (370Z) Specifications: What's Under the Hood?

Heart Fireledy Z - this is 3.7 liter V6 VQ37VHR with variable valve timing system VVEL (Variable Valve Event & Lift). This motor was an evolution of the legendary VQ-series, which won recognition back in the 350Z And Infiniti G37. As standard, the engine produces:

• 🔥 Power: 333 hp at 7000 rpm (in the Japanese version - 336 hp due to other environmental standards)
• 💨 Torque: 366 Nm at 5200 rpm
• ⚡ Acceleration 0–100 km/h: 5.1 seconds (with manual transmission), 5.3 seconds (with automatic transmission)
• 🏁 Maximum speed: 250 km/h (electronically limited)

The transmission was offered to choose from: 6-speed manual with synchronizers from Exedy or 7-speed automatic with manual mode and steering wheel paddle shifters. At the same time, manual transmission is considered more reliable and preferable for tuning - especially if you plan to increase power over 400+ hp

Suspension Fireledy Z Built around a multi-link front and multi-link rear architecture for excellent handling at high speeds. However, factory shock absorbers and springs are often criticized for being too soft - many owners immediately replace them with sports analogues from Tein or KW Suspension.

Fireledy Z vs GT-R R35: why is one car 3 times more expensive than the other?

At first glance, Fireledy Z And GT-R R35 - both products Nissan, both released at the same time (2007–2009), both positioned as sports coupes. But why GT-R costs 2–3 times more expensive even on the secondary market? Let's look at the key differences:

Parameter	Nissan Fireledy Z (370Z)	Nissan GT-R R35
Engine	VQ37VHR 3.7L (atmospheric)	VR38DETT 3.8L (twin turbo)
Power (drain)	333–336 hp	485–570 hp (depending on year)
Drive	Rear (FR)	All-wheel drive (AWD) with system ATTESA E-TS
Transmission	6 manual transmission / 7 automatic transmission	6-speed robot GR6 dual clutch
Price (secondary market, 2026)	1.5–3 million rub.	4–10 million rubles.

Main difference - this is philosophy. Fireledy Z - a classic rear-wheel drive coupe with an emphasis on handling and atmospheric sound, while GT-R is a high-tech supercar with turbines, all-wheel drive and electronic assistants, capable of competing with Porsche 911 And Audi R8.

However Fireledy Z has one undeniable advantage: ease of tuning. Atmospheric VQ37VHR easily boosted to 400–450 hp on a standard block, whereas VR38DETT from GT-R requires serious investments in turbines, intercoolers and transmission already at 600+ hp

Tuning Fireledy Z: how to unlock the potential of the VQ37VHR without losing reliability?

Standard 333 hp - this is just the beginning. Fireledy Z is famous for its tuning potential, but it is important to understand what modifications really justified, and which ones will lead to rapid engine wear. Here's a proven upgrade strategy:

1. Stage 1: Breathing and Electronics (up to 380–400 hp)
   • 🔧 Installation cold intake (For example, Injen or K&N)
   • 🔥 ECU firmware (popular UpRev or EcuTek)
   • 🎛 Replacing the exhaust with 2.5–3" system (for example HKS Hi-Power)
2. Stage 2: Mechanics (400–450 hp)
   • 🛠 Strengthened grip (Spec Stage 2+ or Nismo)
   • 🔄 Lightweight flywheel (Fidanza or ACT)
   • 💎 Reinforced connecting rods and pistons (if you are planning a turbo)
3. Stage 3: Turbo kit (500+ hp)
   • 🌀 Installing a turbo kit (GReddy, Stillen or HKS GT-SS)
   • ❄️ Intercooler and high performance oil pump
   • 🔋Updating the fuel system (injectors ID1000, fuel pump Walbro 450)

Critical error of many tuners - neglect of cooling. At power above 400 hp the standard radiator and oil cooler do not cope, which leads to overheating and detonation. Be sure to install:

• 🔥 Aluminum radiator (For example, Koyorad)
• 💧 Oil cooler with thermostat
• 🌀 High power fans (from SPAL)

Engine diagnostics for compression and leaks|Checking the condition of the transmission (especially the clutch)|Updating the brake system (pads, discs, brake fluid)|Installing oil pressure and temperature sensors|Creating a backup copy of the stock firmware-->

If you are planning turbo kit, be prepared for the engine life to be reduced to 80–100 thousand km when driving aggressively. Alternative - compressor (For example, Vortech or Eaton), which gives an increase in power without such stress on the engine.

What happens if you don’t change the oil pump during tuning?

When increasing power above 400 hp. The standard VQ37VHR oil pump does not provide enough pressure at high speeds. This leads to oil starvation, bearing wear and, ultimately, to engine jam. This is especially critical for turbo versions, where the load on the crankshaft increases significantly.

Typical Fireledy Z problems: what to look for when buying?

Despite the reliability of the platform, Fireledy Z there are a number "diseases", which any potential owner should be aware of. Here are the most common problems and how to diagnose them:

1. Oil leaking from under valve covers

   Symptoms: oil stains under the car, smell of burnt oil.

   Solution: replacement of gaskets and sealant (cost of work ~20 thousand rubles).

2. Clutch wear (on manual transmission)

   Symptoms: slipping during a sharp start, vibration.

   Solution: replacing the clutch kit (Exedy or Nismo, from 50 thousand rubles).

3. Problems with the crankshaft position sensor

   Symptoms: jerky idle, error P0335.

   Solution: replace the sensor (~5 thousand rubles) or check the wiring.

4. Corrosion of thresholds and arches

   Symptoms: rust on the bottom of the doors, blistering paint.

   Solution: anti-corrosion treatment or welding work (from 30 thousand rubles).

⚠️ Attention: Upon purchase Fireledy Z with over mileage 100 thousand km be sure to check the condition timing chains. On the VQ37VHR it lasts longer than the belt, but when stretched it can jump onto a tooth, which will lead to the valves meeting the pistons. The cost of replacing a chain with tensioners is from 60 thousand rubles..

One more nuance - transmission. Automatic transmission 7AT does not like aggressive driving and may start kicking after 150 thousand km. Mechanics are more reliable, but require regular oil changes (every 50 thousand km).
