RB 70mm 'Big Daddy' Exhaust Manifold

RB 70mm V-Band (Big Daddy)

Finally, we can show you one of our most complex designs.
Like our RB High Response manifold (Reverse Rotation) this design will fit RB20/25 and 26.
You can also use the same model to fit an RB30 bottom end, with its taller deck height.

We used a @garrettmotion G45-1450 and a G40-900 for the development of this manifold along with a @turbosmarthq 50mm wastegate.
If you want more flow you can simply cut and weld a 60mm wastegate/flange on.

You can also run @precisionturbo 6870 through to 8685

Big shout out to both @platinumracingproducts and @birrong_automotive for their assistance with the development. Birrong will also be testing one very soon on a special R34 GTR with the special 3.2L combo that they offer.

We designed this so that if you start with a build and it ends up a little crazy and the motor goes 3L-3.4L you can still use the same manifold.

This design also retains AC and Power steering with the HICAS pump, plus has heaps of space for easy oil and water lines and space for our thermal management option that will be later available.

Note:

• If you are going to run a Precision Turbocharger a modification is required to be made on the turbine housing

At ARTEC we have revolutionised the turbo manifold industry with our industry-leading SUS347 stainless steel investment cast manifolds.

All of our manifolds are engineered and designed from the ground up, CFD simulated and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance, resistance to heat pooling and cracking, plus a beautiful smooth exterior finish.

Designed and tested in Australia, backed with a lifetime warranty.
