This red Ultima GTR is 99% done. I've taken great care in building this GTR, but need to sell due to loss of job. Posting here first, before eBay.

The car has zero miles, stock rear wing, PS-II tires (stock sizes), Intrax dampers, AP brakes, and two DOT windshields. The LS7 was dyno-tuned and made 564 HP and 520 Lb/Ft with a BigStuff3 ECU.

The G50/52 transaxle was built by California Motorsports with a cable shift, Quaife diff, a 0-60 mph first gear, 100 mph second gear at 7K RPM. The engine has been started in the car and runs beautifully.

All that's remaining is to put in the windshield, light covers, and side windows, which are all included, some wiring, and charge the A/C. There are two SPA fire systems included. The car is also wired for video and computer.  Not sure I have the correct A/C compressor.

The only thing I can think of to build or buy is an air box for the filter.  I was planning on building one from aluminum sheet and covering it with gold insulation film.  The video cables contain a co-ax line and power.

Here's a picture of the rear AP brakes.  You can also see the cable shift on the side of the G50/52 through the chassis.

 

In these photos, you can see the panel behind the seat for the rear hoop.  It's been carpeted, insulated on the back, and is ready to attach, but not permanently fixed yet.  I was considering using RivNuts rather than rivets so as to have easier access later.  This might be a change you will want to make.  You can also see the location of the two fire bottles.  One is electric; the other cable.  The cable is mounted under the panel at the middle.  Electric button on the panel.  You can also see a bracket next to the fire bottles to hold the activation cable, wires, and A/C lines.  There is a gray conduit that runs through each luggage compartment for extra wires, or whatever you need to run from the front to the back.

 

On the left side, you can see some of the detail in mounting the heater lines.  Notice the rubber lined metal clip towards the front on the heater line.  These were used throughout the car for hoses and wires, rather than the standard fragile plastic clips.  The additional opening is for easy access to the heater valve, should it be required.  The center section is installed now.  The entire interior has been installed, but since removed to facilitate easy wiring of the panel.

 

Clear shot of the shifter location before installing cables.  The cables seen are for the e-brake.

 

 

Behind the custom passenger-side foot panel, I added six relays (Painless Performance).  Two are used for the transaxle pump and oil cooler fan.  The relays are fused between the battery and relay block.  The fuses feed the terminals and power is pulled from there to each relay.  The thin, black wires go to switches of your choice.  The thicker wires are the power supply to your device.

 

Here's a picture of the engine bay before the final engine fitment.  You can see the -12 line between fuel tanks here.

 

The fuel tanks were coated with "Herculiner" pick-up truck bed liner.

 

This is the concept and start of the panel.  Additional photos will show the more complete layout. 

 

This is the remote oil filter and below is the remote take-off from Canton.  The yellow wire is the new, heavy charge line from the alternator, which is now protected and neatly tucked away.  The oil lines are protected by wrapping with radiator hose, so as not to rub on themselves, the chassis, or any other lines/wires.

 

In this early build shot, you can see the top panel added to the chassis as a stiffener.  There's a lower panel, as well, which functions to hold a dome light (not supplied).  There is wiring installed for a dome light to be added.  The LS7 is in the background.

 

Jack's access panels added.  I mirrored the pattern to make both sides.  These are great and provide easy reach to adjust pedals and electrical.

 

Recent.  Just before engine start.

 

Oil cooler install.

 

Transaxle pump, filter, cooler.  There's a fitting for a sensor in the filter, if you would like to have trans temp or oil pressure.

 

The air horns are loud!  Notice the use of rubber-lined metal clips for all harness fasteners.
