About Product
With our direct-fit fuel injector replacement, you can make sure that your Nissan 300ZX (Z32) VG30DETT engine runs at its best. This 370cc/min injector is made to OEM specs (16600-67U01) and has 4-hole nozzle technology that makes fuel atomization better. This gets rid of rough idle, cold start problems, and lean/rich codes (P0171/P0174). The Viton seal and ethanol-resistant structure keep leaks from happening and can handle modern E10-E15 fuel mixes. It comes with all the O-rings and cushions you need for quick installation. It's great for daily cars, weekend cruisers, and upgraded turbos with up to 370HP. This long-lasting, precisely made solution comes with a 12-month warranty and will bring your 300ZX's factory performance back to life.
Products Advantage
1. Precision Flow Matching for Best Performance
Our OEM-spec fuel injector (16600-67U01) gives you exactly 370cc/min at 3 bar pressure, which makes sure that your Nissan 300ZX VG30DETT engine gets the best fuel atomization. This precise calibration gets rid of lean/rich circumstances that might cause P0171/P0174 fault codes in older turbocharged engines. Our injectors have a steady flow rate across all RPM ranges, which is important for twin-turbo configurations where fuel starvation can cause detonation under boost. This is better than aftermarket options. This injector gives you the perfect air-fuel ratio for both daily driving and fast acceleration, whether you have a factory ECU or an aftermarket tune.
Important Benefits for Owners of the 300ZX:
Stops hesitation during WOT (wide-open throttle) on upgraded 300ZX turbos
Stops lean spikes when the boost pressure is higher (14+ psi)
Brings back the factory-level drivability in Z32 cars with a lot of miles on them.
2. Turbo-Ready Building for Engines That Have Been Changed
Our injector was made just for the needs of forced induction. It has a laser-welded stainless steel body and an armored solenoid coil that can handle fuel pressure of 75 psi or more for a long time. This is the best upgrade for owners of 300ZXs who are running:
Larger turbochargers (HKS GT2530, GT2871R)
Fuel pressure regulators that are not made by the manufacturer
E85 conversions (with the right tuning)
Cheap copies don't work well in high-heat turbo situations, but our injector's thermal-stable design stops coil burnout, which is a regular problem near the 300ZX's rear turbo bank. The EV1 connector lets you plug it in and play without having any adaptor harnesses.
Why This Is Important for Your 300ZX:
No more fuel leaks from fractured injector bodies, which is common in engines with more than 150,000 miles on them.
Handles abuse on track days without losing flow
3. Technology for Nozzles That Clean Themselves
The 4-hole laser-drilled nozzle has spray patterns that are tuned for pulsation and actively stop carbon buildup, which is a big problem for 300ZX twin-turbos that are utilized for short journeys. Each firing cycle has a micro-scrubbing impact that lowers:
Cold starts that don't work because to clogged injectors
Rough idle after parking for a long time
Unburned fuel might harm the catalytic converter (P0420 codes).
This is really useful for:
People who drive to work in the city and have to stop and go
Show/store 300ZXs that sit for weeks
Engines with a lot of miles (100,000+ miles)
4. Seals that don't break down in modern fuels
The upper and lower Viton seals are made to withstand E10-E15 gasoline mixtures, which solves two long-standing problems with the 300ZX:
Ethanol absorption causes injector seals to swell, which leads to fuel leaks.
Electrical terminals that have rusted because of fuel that has been contaminated with water
This is why our injector is the best choice for:
US owners who use regular pump gas
Brazilian and European 300ZXs that run on E20 to E25 are ready for the future when ethanol requirements are stricter.
5. Easy to install with plug and play
Our injector is made to be a direct replacement for the OE part and works with:
Stock 300ZX ECU (NA/Turbo from 1990 to 1996) Nismo upgrade routes from 270cc to 370cc
Aftermarket rails (Aeromotive, DeatschWerks)
To install, you only need:
A 10mm socket for rail bolts
Tool for disconnecting the fuel line
New O-rings are included.
Main application scenarios
Commuting every day with traffic that stops and goes
Our fuel injector is great for city 300ZX owners since it makes acceleration smooth and keeps the engine running smoothly when you're not driving. The 4-hole nozzle cleans itself, which stops carbon accumulation, a common problem while driving short distances.
The seals are also resistant to ethanol, so they can take modern E10-E15 fuel without breaking down. Say goodbye to harsh idling and hesitation when you start your car, especially in Z32 vehicles with more than 100,000 kilometers.
Driving with the family or on the weekend (focus on dependability)
Our injector gives 300ZX owners who use their car as a weekend cruiser OE-level reliability and a steady flow of fuel. The 370cc/min flow rate is set with great care to make sure that it works well on both highway trips and spirited excursions on backroads.
Our Viton-sealed injector won't leak or break early like cheap copies. This makes it perfect for maintained 90s JDM classics.
Fixing common fuel problems with the 300ZX
If your 300ZX with two turbos has:
Lean/rich codes P0171 and P0174
P0300 (random misfires)
There is a fuel smell at the injectors (leaking seals).
Our injector fixes the problem directly by bringing the air-fuel ratio (AFR) back to normal and getting rid of turbo lag caused by clogged nozzles. You don't have to reset the ECU; you can just plug it in and run.
Upgrades for performance and the turbo
For modified 300ZX turbos that are running:
Larger turbos (HKS GT2530, GT2871R)
ECUs from other companies (Haltech, AEM)
More boost pressure (14+ psi)
Our injector can handle 75+ psi and has a steady flow rate, so it won't cause lean situations when the boost is on. It's a must-have for builds with 400+ HP. The body is laser-welded, so there won't be any leaks, even when you're on the track or drifting.

Frequently Asked Questions
1. Is this an exact replacement for part #16600-67U01 from the original manufacturer?
+
-
Yes! This fuel injector is a perfect match for the OEM 16600-67U01, therefore it will fit perfectly in all 1990–1996 Nissan 300ZX 3.0L V6 Turbo (VG30DETT) vehicles.
2. Will this work on 300ZX versions that don't have a turbo?
+
-
Yes! It works with both NA and turbo 300ZX 3.0L V6 engines.
3. Does this injector work with E85 fuel?
+
-
No, it is just for gasoline/E10-E15 mixtures. We suggest our high-flow racing injectors for E85 compatibility (get in touch with us for more information).
4. How does this compare to OEM injectors from Denso or Hitachi?
+
-
Same flow rate (370cc/min), but with superior Viton seals that can handle ethanol better. There is no difference in performance between these and brand-new OEM injectors.
5. After installing, do I need to reset the ECU?
+
-
Not required, but suggested for best performance. To clean adaptive fuel trims, just unplug the batteries for 10 minutes.
