Project Nissan Skyline R33 GT-R – Part 4: Borg Warner Turbo and Vibrant exhaust install
Ross’s first order of business was installing the Full Race RB26 manifold to the cylinder head, and then the Borg Warner 8374 EFR turbo on top of it. The water-cooled turbo’s water is fed via the factory coolant system. MKC used a Turbosmart block-off plate for the integrated blow-off. Anyone who’s ever had a top-mount turbo installed knows just how exciting this first visual can be. I’ve been through several top-mount setups in various cars–trust me, it never gets old (unless you’re just boring, bro).
Next, Ross got to work on the 3-in downpipe using one of the Vibrant Performance “J” bends. He’s known around town for having very clean weld beads.
Vibrant Performance also sells these 3-ID flexible bellows, giving much easier fitment and maneuvering during exhaust fabrication.
Ross fabricated the Vibrant Performance bellow into the lower part of the downpipe with a Vibrant V-band clamp. Given the 3-in ID piping, I was pleasantly surprised to see how much room there was from the surrounding parts and chassis.
Right after the downpipe comes the 3-in Vibrant resonator. This helps quiet things down and keep droning to a minimum.
