Nissan RB26 70mm V-Band 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 bottomend, 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 7675 and we will be testing up to the 8685 soon.
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 their special 3.2L combo that they offer.
We designed this so 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.
