Injector Dynamics Fuel Injectors for Nissan

If you're chasing a fuel injector sizing guide for RB26, SR20DET, VQ or VR38, this is where to start. We fit and recommend Injector Dynamics injectors on Nissan builds across Sydney and at track days out at The Bend, from mild street SR20s to serious GT-R drag cars. Every set comes with full characterisation data, so your tuner isn't guessing at fuelling.

The ID1050x is the most common starting point on Nissan platforms. A set of six covers most single-turbo RB26, VQ35 or VQ37 builds on petrol, and a set of four suits the majority of SR20DET street and track cars. Step up to the ID1300x once E85 and bigger turbos push power levels higher, particularly on R35 GT-Rs where big power is the norm rather than the exception.

All ID injectors handle petrol, E85, E100 and methanol without issue, thanks to stainless internals built for corrosive fuels. That matters on Nissan platforms where E85 conversions are common practice, not a rare upgrade.

Why Injector Dynamics for Nissan

Nissan's turbo platforms are all fuel-hungry once you move past stock boost. The RB26's factory side-feed injectors run out of headroom fast, the SR20DET's factory injectors don't cope with E85 or a bigger turbo, and the R35's twin-turbo VR38DETT can push power high enough that even mid-size aftermarket injectors max out. Injector Dynamics ships every set with dynamic slope flow rates, dead time values across voltage and pressure, and flow matching data your tuner loads straight into the ECU. That means correct fuelling from the first start-up instead of trial-and-error tuning. We stock ID because we've seen the difference clean characterisation data makes on a dyno session, particularly on multi-cylinder engines like the RB26 and VR38 where injector-to-injector variance shows up as uneven cylinder trims.

Fitment & Installation

RB26 builds converting from side-feed to top-feed will need a compatible fuel rail; a set of ID1050x injectors pairs directly with a top-feed rail conversion. SR20DET owners face the same side-feed limitation on S13/S14 engines, so budget for a rail upgrade alongside your injectors. VQ35/VQ37 and VR38DETT engines are already top-feed from factory, so injector swaps are more straightforward, though larger injector bodies can need updated fuel rail O-rings or spacers depending on your rail. Always confirm injector length and O-ring size against your specific rail and intake manifold before ordering, especially on modified or hybrid engine combinations.

FAQ

Will ID injectors fit my RB26 without a rail conversion?
No. The RB26's factory side-feed rail doesn't accept top-feed injectors like the ID1050x. You'll need a top-feed rail conversion, such as the Radium Engineering RB26 rail, as part of the install.

What size injector do I need for an E85 SR20DET?
A set of four ID1050x injectors covers most E85 SR20DET builds at moderate boost. The ID1050x is rated at 1000cc/min (nominal), with actual flow varying by fuel pressure and fuel type, so your tuner will work from the ID-supplied flow data rather than the headline number. Once you're pushing more boost or a bigger turbo, step up to the ID1300x. Exact sizing depends on turbo, boost and target power, so check our injector sizing guide or contact us.

Are Injector Dynamics injectors compatible with Haltech, Link and MoTeC?
Yes. Characterisation data is provided in formats compatible with all major standalone and piggyback ECUs used on Nissan platforms, including Haltech, Link, MoTeC, EcuTek and UpRev.

Do you ship Australia-wide and what's the warranty?
Yes, we ship Australia-wide. Injector Dynamics products carry the manufacturer's standard warranty against defects; contact us for specifics on your order.
