1997 Limited Edition Toyota Supra Twin Turbo
Owner: Stuart Hagen
New~! January 2008. I finally received the long awaited set of Hybrid GT28R non-ball bearing turbo's from BNR. The design and workmanship is superior. A lot of work went into these to provide a unique style and design. They are VSR balanced to 150,000rpm (24psi) and have the capability to achieve 30 psi with the right mods. There compressor map is very similar to a GT28RS. They will install totally OEM with only a few modifications like cutting the rubber couplers 3/8" and notching the heat shield a little for the oil inlet. They will be sequential if desired. More later when installed~!
(Working on the oil and water line kit right now.)
A custom manifold will soon be available, but not recommended unless additional mods are done. Since these turbo's have the possibility for 600whp fuel systems are required. If the goal is 500-525 whp, then fueling may not be needed and definitely not the manifold.
May 30, 2008 GT28 Twin Turbo Conversion is Here~! Now for sale.

*The Following are pics of my latest Low Budget Stereo Upgrade:
The theory of this install was to use the OEM amp to run the Subwoofer only. The new radio is a Nakamichi CD500 with a built in 50W amp per channel. This is a MP3 player. It has RCA outs, and has 10 different illumination themes. I have chosen *green/green* as being closed to OEM. We have used all integration harnesses purchased on Ebay for about $50 total for all 3. These are used to have the entire system plug and play, no wire cutting whatsoever. We also installed better door and rear speakers. We however kept the OEM subwoofer. This unit sounds extremely awesome. The windows and mirrors actually vibrate from all of the bass. The entire cost for this systems with radio and speakers is approx $700. I want to thank Steve Ishii for all of his help on the wiring diagrams, and Wes for his awesome job in the speaker fabrications.

Oil Cooler/Power Steering install
I finally got around re-configuring my Power Steering cooler (required after 3-Row install) so I could incorporate a 19-Row Oil cooler. So I came up with a "V"-Mount approach. I tested it today at a HPDE and my oil temps are now around 200-210 on a 78 degree day, 2 weeks ago I was getting real close to 230 degrees and decided it was time to install this thing.
