PRP (Platinum Racing Products) 2JZ Parts: What They Make and Why Builders Use Them

Platinum Racing Products — known universally as PRP — is an Australian performance engineering company that has become one of the most trusted names in SR20, RB26, and 2JZ engine builds worldwide. Their parts turn up on the best-built cars at time attack events, drag strips, and dyno sessions from Australia to Japan to the United States. If you are building a serious JDM engine, you have almost certainly encountered PRP — and if you have not, this guide explains why you should.

Who Is PRP — Platinum Racing Products?

Platinum Racing Products was founded in Australia with a specific focus on Nissan RB-series, SR20, and Toyota JZ-series engines. While many performance brands offer generic parts that happen to fit various engines, PRP builds engine-specific, application-engineered components. Their coil kits, block braces, and ignition trigger systems are designed specifically for the platforms they serve — tested on high-boost builds and validated in the environments where those engines run hardest.

That specificity is why PRP has become a standard fitment on top-level builds despite being based in Australia. J-Spec Garage stocks PRP components with domestic US availability and a price match guarantee — no international shipping wait times on the items in our catalog.

PRP Ignition Coil Kits for the Nissan SR20

The SR20DET's factory ignition system is adequate at stock boost but becomes a limiting factor on modified engines running elevated cylinder pressures. PRP's IGN-35A coil kits replace the stock coils with individual coil-on-plug units that deliver higher spark energy for consistent ignition at high boost.

J-Spec stocks three SR20-specific PRP IGN-35A configurations — order the correct one for your specific SR20 cylinder head variant:

• PRP IGN-35A Coil Kit — Nissan SR20 GTi-R — for SR20 engines in GTi-R configuration
• PRP IGN-35A Coil Kit — Nissan SR20 Big Hole — for SR20 heads with the larger-diameter spark plug hole (most common S14/S15 SR20DET configuration)
• PRP IGN-35A Coil Kit — Nissan SR20 Small Hole — for SR20 heads with the smaller-diameter spark plug hole (early S13 configuration)

If you are unsure which variant your engine uses, check your spark plug bore diameter — or contact J-Spec before ordering and we can help confirm the correct fitment.

PRP Ignition Coil Kit for the Nissan RB20/RB25/RB26

PRP's RB-series coil kit uses R35 GT-R VR38 coils mounted in a custom bracket to upgrade ignition on the RB20, RB25, and RB26DETT. The R35 coils deliver significantly higher spark energy than the RB's factory coils — a meaningful upgrade on any RB build pushing boost above stock levels.

• PRP Ignition Coil Kit — Nissan RB20/RB25/RB26 (with R35 VR38 Coils)
• PRP OEM Coilpacks — Nissan GT-R R35 — the R35 OEM coils used in the bracket kit, available separately as a service item

PRP VR38 Coil Loom for Toyota 1JZ/2JZ

The 2JZ-GTE factory ignition coils face the same limitations as other OEM units under sustained high-boost use. PRP's coil loom kit adapts R35 GT-R VR38 coils to the Toyota 1JZ/2JZ platform — delivering the same high-output ignition upgrade that the RB kit provides, purpose-fitted for the JZ architecture.

• PRP VR38 Coil Loom — Toyota 1JZ/2JZ — the loom/harness kit for adapting R35 VR38 coils to the 1JZ or 2JZ cylinder head. Note: this is the coil loom and harness; R35 OEM coilpacks are sourced separately.

PRP RB Engine Block Braces and Main Cap Cradles

Beyond ignition, PRP makes structural reinforcement components for the RB-series block — a common upgrade on high-power RB25 and RB26 builds where main cap walk becomes a concern at sustained high boost.

• PRP Block Brace — Nissan RB26 2WD
• PRP Block Brace — Nissan RB25/RB26 AWD
• RB Integrated Main Cap Cradle — the full main cap cradle assembly for maximum RB block rigidity at high power levels

Additional PRP Components at J-Spec

J-Spec also stocks:

• PRP Integrated Iron Engine Block Brace — Nissan SR20
• PRP A/C Relocation Bracket Kit — Nissan RB20/RB25/RB26/RB30
• PRP Street Series Camshaft Ignition Timing Kit — RB20/RB25/RB26
• PRP Pro Series Camshaft Ignition Timing Kit — RB20/RB25/RB26
• PRP RB25 Engine Exhaust Heat Shield
• PRP V2 Billet Exhaust Side Solid Engine Mount — RB26

Frequently Asked Questions

Which SR20 PRP coil kit do I need?

The correct kit depends on your SR20 cylinder head's spark plug hole diameter. The Big Hole variant fits most S14 and S15 SR20DET engines — if you are not certain, confirm with your engine builder or contact J-Spec before ordering. Ordering the wrong variant means the coil body will not seal correctly in the plug tube.

Does the PRP RB coil kit work with my standalone ECU?

Yes. PRP's RB and 2JZ coil kits are compatible with all major standalone ECUs used on these platforms — Haltech, Link, AEM, ECUMaster, MoTeC, and others. The kits use R35 VR38-type coils that any standalone with coil-on-plug ignition outputs can drive directly.

Is PRP available in the US?

Yes. J-Spec Garage stocks PRP ignition, block brace, and engine management components with US-based availability. No international shipping wait times or import duties. Browse the PRP collection at J-Spec Garage.
