yeah it's a racecar, I figure each one of those holes should give me a tenth in the quarter...lol

I got to work on some turbo plumbing; I used a combination of 2-1/2” and 3” stainless tubing. I started with a pile of mandrel bends and started cutting.
The early 3 bar grilles have an extra support link that connects to the frame, this was the first obstacle to deal with. After some measuring, looking, measuring and a lot more looking I started cutting. I started off with the passenger side (IC to engine).









The passenger side (high pressure turbo to IC) proved to be much simpler. I turned the compressor housing and it ended up beinga straight shot…blind luck on that one





Also, bit of a course change…decided to go with compounds (HX30 over an HX35). I got to work mocking up the hot pipe. The area between the exhaust manifold and inner fenders looked gigantic when there was nothing there…needless to say, space disappeared real quick when I started hanging the turbos





more to come…
