The Evolution of Our Nissan RB Intake Manifolds

If you’ve been following CPC from the start, you’ll know we didn’t just wake up one day and start making billet manifolds. Like most good things, it started in a small shed, with a welder, some scrap aluminium, and a bit of stubbornness.

Our very first proper product was the RB30 Street Intake Manifold. Nothing fancy,  just a tough, well-thought-out sheet metal manifold designed to actually fit into tight bays and do the job. It was made for street cars, built by hand, and tested on our own rides. That’s where CPC really began.

Stepping Things Up – The Billet Era

Fast forward a fair few years and we were elbow-deep in billet. Our RB26 Billet Intake Manifold was our first major leap into CNC territory, not just for looks (although let’s be honest, it looks bloody good), but for flow, strength, and repeatability.

This was the stage where Ariel started nerding out over injector angles, internal velocity stacks, and DBW compatibility. We wanted something that’d work on a big-power street car or even a weekend warrior with serious goals. And It hit the mark.

Built for Abuse – The RB Drag Setup

Then came the people chasing 7s and 8s. That’s when we knew we had to go all-in.

The RB26 Billet Drag Manifold is the final boss version. Massive runners, no compromises, full modularity, everything about it is designed for one thing: pushing as much air through that RB as humanly possible.

If you’re chasing big boost and even bigger numbers, this is the setup.

Why We Bother

We don’t just build stuff for the sake of it. Every version of this manifold, from the OG street setup to the billet drag monster, exists because we listened to the people actually using them. Every weld, cut, and CAD tweak came from real-world feedback and testing.

CPC started with a street manifold and a goal to make parts that work. We’re still doing exactly that, just with more tools, more data, and a lot more billet.
