RB30 Low-Mount Exhaust Manifold Heat Shield

Protect your RB30 setup from excessive exhaust manifold heat with the Rajab Racing RB30 Low-Mount Exhaust Manifold Heat Shield.

Designed specifically for our exhaust manifold, this heat shield sits lower and closer to the manifold, providing improved heat coverage around the intercooler piping and silicone couplers.

The increased shielding helps reduce heat exposure to the silicone piping, helping prevent excessive heat soak, deterioration and heat-related splitting — giving your setup improved reliability under demanding conditions.

RRD TB48 Throttle Body Adaptors

squaroe — Tue, 03 Jun 2025 16:05:22 +0000

Price is $120plus GST

TB48 Throttle Body Adaptors for Rajab Racing Intake – Manual & Auto Specific

We’re proud to introduce our newly developed TB48 throttle body adaptors, custom designed to bolt directly onto the Rajab Racing intake manifold, allowing for the use of OEM throttle bodies. Whether you’re running a manual or automatic TB48 setup, we’ve got you covered with two purpose-built adaptors, each tailored to fit your specific application.

Why these adaptors?

The Rajab Racing intake is a popular choice for high-performance TB48 builds, but fitting a factory throttle body typically requires custom fabrication or aftermarket alternatives. Our adaptors eliminate that hassle by allowing you to bolt the factory throttle body straight on, keeping things simple, reliable, and cost-effective.

Product Highlights:

Two Versions Available – One adaptor for the manual TB48 throttle body, and another for the automatic TB48 throttle body. No compromise fitment.

Direct Bolt-On Compatibility – Designed to work seamlessly with the Rajab Racing intake manifold. No cutting, welding, or modifications needed.

OEM Integration – Retain your factory throttle body and sensors while benefiting from the performance gains of the Rajab Racing intake.

Precision Machined – Built from high-quality materials with tight tolerances to ensure a leak-free, reliable seal under all conditions.

Whether you’re building a street car, race truck, or weekend warrior, these adaptors let you take advantage of the Rajab Racing intake without giving up the reliability and drivability of your OEM throttle system.

RRD RB30 Performance Rocker Cover

squaroe — Wed, 21 May 2025 03:42:42 +0000

Price $1100 plus GST

NEW RELEASE: RB30 Performance Rocker Cover – Designed for the Street and Built for the Track

We’re excited to launch our all-new Nissan RB30 Performance Rocker Cover, a product born from real-world experience and engineered to help solve the most common issues RB30 owners’ face — whether you’re working with a stock engine, a street-built setup, or a full-spec race build.

This rocker cover is more than just a good-looking addition under the bonnet. At its core is a purpose-built internal baffle system that controls oil splash and promotes proper oil return. By directing oil back toward the sump rather than into your catch can, it dramatically reduces the chance of overfilling and keeps your crankcase ventilation system functioning at its best — especially during excessive acceleration or sustained high-RPM driving.

Taking it a step further, we’ve added external oil return cavities that allow oil to bypass the head and return directly to the sump. This design feature helps prevent oil starvation — a well-known weak point in the RB platform — by keeping oil where it’s needed most, even under the most demanding conditions.

To handle the demands of high-boost and high-horsepower builds, the cover also comes equipped with dedicated crankcase pressure relief fittings. These allow for adequate ventilation, helping to reduce internal pressure, lower the risk of blow-by, and protect engine internals during aggressive driving or track use.

Every unit is precision-machined for a direct bolt-on fit to all RB30 heads, making it a perfect upgrade for both standard and high-performance applications. Built from quality materials and engineered with longevity in mind and completely made in Australia, this cover delivers durability and performance you can count on.

On top of the function, we’ve made sure it brings the form too.

The RB30 rocker cover is available in three standout finishes:

Gloss Black for a stealthy, clean look
Bright Red for a bold, motorsport-inspired appearance
Raw Aluminium for those who want to customize or show off a raw alloy finish
All fittings are -12 ORB
Oil filler cap is the same thread as factory Nissan

You also have the option to run it with or without the iconic Rajab Racing logo, giving you full control over your engine bay aesthetic.

This is not just another rocker cover — it’s a performance-driven upgrade that addresses oil control, crankcase ventilation, and reliability in one complete package.

Available now – limited first-run stock.
