Nissan R33 RB25 S2 - R8 Coil Upgrade Kit

*MOUNTING ADAPTOR IS NOT SOLD INDIVIDUALLY, please do not ask*

Our R8 coil conversion kits are the most favored amongst high performance builds with a budget in mind. We offer no-fuss plug and play kit to suit R33 RB25 S2, photos on the slideshow above are exactly what you will be getting and installation manual (including ignition dwell time adjustment) is available on the tab above at your disposal. No BS, just pure performance and quality.

These coils are proven to support high boost application. We ran these coils to 36 psi (on Garrett GTX35R) and straight-off-the-box NGK BKR7E spark plugs (~0.95mm gap) with no ignition break down in-sight. Next time you choose an ignition coil upgrade kit, ignore the marketing ’horsepower rating’ as often advertised. Ask the seller whether their coils are genuine and what power/boost their kit has achieved at what plug gap!

Our kit has been used and recommended by road-going performance vehicles, circuit racers and drifters.

O Designed for forward facing plenum only, otherwise, modification to stock J-pipe is required to fit (message us for instructions)

! Does not fit OEM coil valley cover as the coils sits higher than OEM.

! Engine swaps are common - it is your responsibility to check your existing ignition wiring loom connectors and cross reference with the photos above!

! Check up tune on your vehicle is highly recommended after installation.

! Known un-supported ECUs: Megasquirt, Microtech and Adaptronic.

✔ Known supported ECUs: OEM Nissan, Haltech, Link, Motec, PowerFC, Nistune, Emtron and MaxxECU.

! We may combine two ignition coils into one box to save on international shipping (reduced volumetric weight)

✔ 100% Plug and Play. No wiring work required, simply install the supplied harness and mounting kit in.

✔ Supplied harness bypasses OEM igniter completely (RB20, RB25 S1, R32 RB26 and R33 RB26 applications).

✔ High temperature and chemical resistant Teflon F.E.P wiring as standard.

✔ Heavy gauge 2mm² wire for power and 1.5mm² wire for signals as standard.

✔ P.E.T wiring loom braided sleeve and connector boots as standard.

✔ Dual wall heat shrinking.

✔ Professionally crimped terminals.

✔ We only use, trust and supply the proven genuine Denso or NGK Audi R8 ignition coils with 1-year manufacturer’s warranty. NOT compatible with Bosch R8 coils due to different coil design.

✔ Top down assembly, CNC machined Billet aluminium 6061 mounting plate with all fasteners included.

✔ Provision to tuck wiring loom underneath the mounting plate for clean slate look.

✔ Coil packs can be removed individually from the mounting plate when installed.

✔ Correct indexing of the coil placement.

✔ Provides lateral support on the upper body of the coil pack (removes dynamic bending stresses on the fragile spark plug in comparison of when no mounting plate is used).

✔ Kit is proudly designed and made in Australia.

Shipping is available worldwide, trackable and insured.

Please note that we do not sell and recommend the use of counterfeit coil packs. Counterfeit products harm the automotive industry and are a hazard to your engine/safety. Be cautious when a seller uses words like “-style” or “-equivalent” to pass on cheap counterfeit products that will not perform.

We do not incorporate a wire loop in our harnesses for use with an inductive timing light as our experience proves it to be an unreliable source. To set ignition base timing, we recommend the use of coil on plug extension lead (such as DAT-Equipment TE010 or the like) to latch your inductive clamp onto for a much more reliable reading.

Please refer to the installation manual section for installation guide and the technical section for further information.

Please allow 5 working days to process your order.

We do not recommend running any cover plate on top of these coil packs. These coil packs have built in heat sinks on the main body which prolongs its’ longevity and performance by allowing some air flow. If you run a vented bonnet, you must run sufficient ducting underneath the bonnet vents to re-direct water away from the top of the engine.

PVC insulated wires require thicker insulating material for the same specification as Teflon insulated wire. Do not be fooled assuming a larger outside diameter wire means having a bigger wire cross section area.

You will need to set up ~2.8ms ignition dwell time at 14V to maximise the coil’s performance and use resistive type spark plugs (i.e. NGK BKR series).

Known supported ECUs: Stock Nissan, Haltech, Link, Motec, PowerFC, Nistune and MaxxECU.
Unsupported ECUs: Megasquirt, Microtech, Adaptronic
