Nissan 370Z NISMO v3.8 1.57x ATS – A Deep Dive into the Ultimate Tuning Package

If you’re hunting for a sports car that blends classic Japanese engineering with modern performance upgrades, the Nissan 370Z NISMO v3.8 1.57x ATS package is worth a close look. This article breaks down what the kit offers, how it changes the driving experience, and why it’s becoming a favorite among enthusiasts who crave track‑ready precision without sacrificing daily usability.
What Makes the Nissan 370Z NISMO v3.8 1.57x ATS Special?
The original Nissan 370Z already boasts a 3.7‑liter V6 that delivers 332 hp and 270 lb‑ft of torque. NISMO’s v3.8 upgrade pushes the displacement to 3.8 L, while the 1.57x ATS (Advanced Turbo System) adds a turbocharger calibrated for a 57 % boost over stock output. The result is a power surge that can exceed 500 hp and 450 lb‑ft of torque, turning the 370Z into a true performance beast.
Key highlights include:
- Engine displacement bump – 3.8 L forged pistons and a reinforced crankshaft.
- 1.57x ATS turbo – a twin‑scroll turbo with a custom wastegate for rapid spool.
- Reinforced internals – forged connecting rods and upgraded head studs.
- ECU remap – a stand‑alone tune that optimizes fuel, ignition, and boost curves.
All of these components are engineered to work together seamlessly, delivering a linear power curve that feels both exhilarating and manageable.
Installation Overview: From Stock to NISMO‑Ready
1. Engine Prep
- Remove the stock intake, exhaust manifold, and turbo (if present).
- Install the 3.8 L short‑block, ensuring proper torque on all main caps.
2. Turbo Integration
- Mount the 1.57x ATS onto the custom‑fabricated exhaust manifold.
- Connect the intercooler piping, making sure the coolant lines are insulated to prevent heat soak.
3. Supporting Systems
- Upgrade the fuel pump and injectors to handle the increased flow.
- Fit a high‑capacity oil cooler to protect the engine under sustained high‑load conditions.
4. Tuning & Calibration
- Load the NISMO ECU map via the OBD‑II port.
- Perform a dyno run to fine‑tune boost pressure and ignition timing for your specific driving style.
The entire process typically takes 12–16 hours for a professional shop, but the performance gains are undeniable.
Performance Gains: Numbers That Speak
| Metric | Stock 370Z | Nissan 370Z NISMO v3.8 1.57x ATS |
|---|---|---|
| Horsepower | 332 hp | 508 hp |
| Torque | 270 lb‑ft | 452 lb‑ft |
| 0‑60 mph | 5.2 s | 3.6 s |
| Quarter‑mile | 13.8 s | 11.9 s |
| Top Speed | 155 mph | 180 mph (limited by gearing) |
The 0‑60 mph time drops by nearly 1.6 seconds, making the car feel instantly more aggressive off the line. On the track, the extra torque translates to quicker corner exits, while the turbo’s low‑lag design keeps the power delivery smooth.
Driving Experience: Street vs. Track
Street Driving
On city streets, the Nissan 370Z NISMO v3.8 1.57x ATS remains surprisingly tractable. The ECU’s adaptive maps provide a comfortable idle and smooth acceleration for daily commutes. The upgraded brakes and suspension—often paired with the kit—ensure confidence when braking from higher speeds.
Track Days
When you hit the circuit, the turbo’s rapid spool (thanks to the 1.57x ATS) means you’re never waiting for power. The car’s balance improves due to the added weight over the front axle, but the NISMO‑tuned suspension compensates with stiffer springs and adjustable dampers. Drivers report a more linear throttle response, allowing them to modulate power through corners without sudden surges.
Maintenance Tips for Longevity
- Regular Oil Changes – Use a high‑performance synthetic oil (15W‑50) and change every 3,000 mi.
- Coolant Checks – The turbo generates extra heat; keep the coolant level topped up and replace it every 12 months.
- Turbo Inspection – Look for oil leaks around the wastegate and intercooler connections.
- ECU Updates – NISMO releases periodic map refinements; keep the software current for optimal performance.
Following these guidelines will keep the Nissan 370Z NISMO v3.8 1.57x ATS running at peak efficiency for years.
Is the Nissan 370Z NISMO v3.8 1.57x ATS Right for You?
Consider the following when deciding if this upgrade fits your needs:
- Budget – The full kit, including installation, typically ranges from $12,000 to $15,000.
- Intended Use – Ideal for drivers who split time between daily driving and occasional track sessions.
