Just remembered this from back in my 300ZX days. I hope you’re sitting down.
I also hope you’re grateful because I remembered this completely randomly, it took a lot of hunting to find it and more again to locate the images and it’s goddam good.
Based on an unregisterable twin-turbo 2+2 auto, converted to run on LPG. Lives in QLD Australia.
And heaps more photos of the whole build on the Photobucket.
