Twins for an rb26 are stuck in 10yr old technology and always will be! For the simple fact no aftermarket suppliers care about them anymore as the engine isnt being produced anymore and never will be.
All of their r&d is being thrown at cars like the r35, evoX (for now), new wrx and of corse universal singles as that will always be their biggest market due to the fact they can be made to fit everything.
But my Gtr will always be twin turbo even knowing the turbos are old tech and getting older every year, but I also have plans to try and bring them closer to this new technology and if it works should be a great kit, if not......well at least I tried something different
