Ever since we noticed it finally yr’s Tokyo Auto Salon, I’ve been ready for HKS to inform us extra concerning the RB26 full piping package 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 goals are product of. Assume Nismo carbon inlet piping and carbon air field on steroids and also you get the thought.
Final yr, the bundle was within the first stage of improvement; 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 automobile. That is actually the one technique to absolutely perceive the complexity of all of it.
For a way fairly this final answer could also be, will probably be difficult for HKS to interrupt it down into packages that make sense for as many customers as potential. For instance, there could find yourself being two variations of the air field, one with an air stream meter flange and one other with out.
Then there’s the turbo fitment. This package has been designed round HKS’s personal GT25-sized GTIII twin-turbo improve, which is by far the most well-liked and broadly used HKS setup amongst Skyline GT-R homeowners. For those who run one thing totally 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 purposes would require a slight redesign, similar going for the air packing containers.
Then there’s maybe essentially the most thrilling a part of all this – HKS is rebuilding their Zero-R BNR32 full automobile, first seen 30 years in the past, to develop the brand new Superior Heritage engine setup. Speak about 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 totally different model of the piping package.
Taking a look at it, this one is perhaps extra monitor/efficiency centered, or only a greater tier model. As you may see, HKS have swapped silicone hoses and conventional steel clamps for AdelWiggins {hardware}.
The Superior Heritage engine itself is now within the testing and improvement part, because the aim HKS have set for gas consumption isn’t precisely simple to attain. Simply to refresh your reminiscences, HKS is aiming to have this engine not solely develop 600hp and powerful and flat mid-range torque, but additionally be capable of return 20km/l (47mpg) gas consumption beneath regular driving circumstances. 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 would require one other model of the carbon piping package 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 spanking new elements and plenty of producers and tuners proceed to reply, making this essentially the most thrilling interval ever to switch, excellent and modernize these vehicles.
