Project Nissan Skyline R33 GT-R – Part 4: Borg Warner Turbo and Vibrant exhaust install
From the resonator there is another V-band clamp down the line, separating the mid section from the rear muffler. We got the universal exhaust hangers from Vibrant as well, and Ross welded them on.
Here’s a full view of the MKC-fabricated Vibrant exhaust system on Project R33 GT-R.
With dual tips, we’re back to more of an OE “plus” look on this GT-R. With nearly all GT-Rs running an aftermarket exhaust, and probably 99% of those running a large single-tip, this is one of my favorite differentiators from the rest of the pack. For some geeky reason I was giddy at the new look. And the sound, my friends, is simply glorious. I will have vids of the exhaust sounds soon.
In Part 3 we discussed using Thermo Tec’s Rogue Series exhaust wrapping. Here is the final result. After a drive, your children can momentarily touch the exhaust wrapping and not burn their hands. More importantly, the wraps will also prevent the exhaust’s heat from doing anything to the hood’s paint.
The new turbo and exhaust wrapping has started to transform the look underneath the hood. It looks significantly cleaner.
Unfortunately, even with our new turbo, the stock injectors and fuel pump are limiting the GT-R to around 340 wheel horsepower on the dyno. We’ll be addressing this next with an assortment of fuel components from Radium Engineering and DeatschWerks. Stay tuned!

  1. Nice! I have an almost identical setup on my 33 ie Fullrace and 8374 0.92 iwg.
    I was going to connect the turbo cooling outlet back to the original spot like you but instead welded an AN6 male onto the radiator top tank which is above the turbo outlet so it thermal syphons when engine cooling down after turning off. This cools down the turbo bearing housing rather than cooking it.
    This was how it worked with the original twins.
    Cannot post a picture here but happy to send you one.
