Ahh, you found my reference site. Only difference is he mounted hi turbo below the mani. I couldn't do that because my is so low ,bilstien shocks, ie springs, ie sways, 3" drop +/-.

It sits about 2" higher than in the pic.
With the stance, brakes, 15" Kosei wheels (14 lbs!) this thing looks anything but stock.
