Project Nissan Skyline R33 GT-R – Part 5: New Fuel System by Radium, DeatschWerks, and AEM!
Here’s a close up of our new Radium fuel rail, fuel pressure regulator and damper, as well as the optional Radium fuel pressure gauge. Anodized black components really dresses up the engine bay nicely, and will last the life of the car.
As mentioned earlier, for the month of July 2021, both Projects R33 GT-R and Supra are residing at the Kansas City Automotive Museum in Olathe, Kansas, for its “JDM Month”. If you’re in the area over the next few days, make sure to drop by to see some cool JDM vehicles the museum’s got on temporary display! They also have a “Cars an Coffee” morning every 1st and 3rd Saturday of each month.
With the black anodized Radium Engineering stuff in there, the engine bay is really starting to look like I had originally wanted. It looks a lot more updated an clean after the MKC installation.
Here’s one last look at how Project R33 GT-R’s engine bay is currently looking, with its new fuel system and black BW 8374 turbo. I’ve very happy thus far.

With the new fuel system, the car drives very smooth. From the get go there have been no fumey smells or leaks. When you turn the ignition key to “power on”, the noisy fuel pump sound I used to have with the NISMO unit is now super quiet with the twin AEM LP340 units. The previous issue I had before with flooding the cylinders upon a cold-start shut off, yeah that issue is gone as well. Everything is looking good and having a new fuel system in a 26-year-old car just adds that added comfort in the back of my mind.

(Editor’s note: We will have more installation pictures from underneath the car in the next installment. Unfortunately a time constraint for when the car was due at the museum eliminated that possibility for me.)

With the fuel system finished, MKC strapped the car back onto the dyno and–while our previous issue of not having enough fuel at that 350whp mark is gone–we’re now facing a minor issue with not having enough spring rate in our BW internal wastegate (12 PSI or so seems to be its limit).  We’re tackling that next with a Turbosmart replacement unit, so in our next installment we should hopefully be seeing some more entertaining horsepower numbers! But first, I have to wait until the month is over before I can steal the car back from the museum. Hey it’s my car, I wonder if I would get arrested? Stay tuned…for the installment, that is. No, I’m not breaking into the…OK moving on…
