Ever since we noticed it finally 12 months’s Tokyo Auto Salon, I’ve been ready for HKS to inform us extra in regards to the RB26 full piping equipment conversion they teased us with.
Again in January 2022, we weren’t solely proven the Superior Heritage RB that HKS is at present engaged on – extra on this in a second – however the kind of piping and air field setup that RB26 desires are made from. Suppose Nismo carbon inlet piping and carbon air field on steroids and also you get the concept.
Final 12 months, the package deal was within the first stage of growth; the design had been locked down and the primary 3D-printed prototype was proven to the world. Quick ahead 12 months to Tokyo Auto Salon 2023, and the printed white segments have magically was pre-preg carbon fiber items.
The result’s one thing fairly spectacular, particularly when introduced in its entirety, all plumbed collectively and out of a automotive. That is actually the one method to absolutely perceive the complexity of all of it.
For a way fairly this final resolution could also be, it is going to be difficult for HKS to interrupt it down into packages that make sense for as many customers as doable. For instance, there might find yourself being two variations of the air field, one with an air movement meter flange and one other with out.
Then there’s the turbo fitment. This equipment has been designed round HKS’s personal GT25-sized GTIII twin-turbo improve, which is by far the preferred and broadly used HKS setup amongst Skyline GT-R homeowners. When you run one thing completely different you’ll have clearance points.
The turbos are mounted onto the inventory forged iron exhaust manifolds and dump spent gasses into HKS outlet pipes.
This primary piping prototype has been designed to suit the BNR32 GT-R. BCNR33 and BNR34 functions would require a slight redesign, identical going for the air containers.
Then there’s maybe essentially the most thrilling a part of all this – HKS is rebuilding their Zero-R BNR32 full automotive, first seen 30 years in the past, to develop the brand new Superior Heritage engine setup. Discuss going full circle!
The iconic GT-R was proven off at Tokyo Auto Salon over the weekend in a largely stripped state, sporting a barely completely different model of the piping equipment.
it, this one could be extra observe/efficiency centered, or only a increased tier model. As you’ll be able to see, HKS have swapped silicone hoses and conventional steel clamps for AdelWiggins {hardware}.
The Superior Heritage engine itself is now within the testing and growth section, because the aim HKS have set for gasoline consumption isn’t precisely straightforward to realize. Simply to refresh your recollections, HKS is aiming to have this engine not solely develop 600hp and robust and flat mid-range torque, but additionally have the ability to return 20km/l (47mpg) gasoline consumption beneath regular driving situations. That’s the place all of the know-how HKS have thrown at it comes into play, beginning with the twin-chamber carbon/billet aluminum consumption plenum, a twin injector setup, twin V-CAM, digital wastegate management and electrical single throttle physique.
You may additionally discover that the vertically-mounted twin-turbo association we noticed in 2022 is not fitted to both show engine. If that turbine placement goes forward, it should require one other model of the carbon piping equipment to be designed and tailored.
It’s actually superb to see how a 30-plus-year-old engine continues to get a lot consideration. Skyline GT-R homeowners are crying out for brand new elements and lots of producers and tuners proceed to reply, making this essentially the most thrilling interval ever to change, excellent and modernize these automobiles.
