Honestly I have no clue on the internal modifications. Most of the power would be made within the cylinder heads, i'm sure a lot of CNC work, valve springs, JWT C8 cams or better, 13:1 compression or so..., could be anything....lolHave they got any spares? I could fit that in mine I'm sure!
With ITB, what is usually done for Air Filtration?
Any idea on what they did for ECU, Custom IM, Valve Springs, Pistons, Crank, Connecting Rods, etc?
That ITB setup you are referring too is the VK56 engine that is in Chris Forsberg's Drift 350z and now installed into his Infiniti M56 Drift car as well.i wonder what an ITB setup costs for our trucks....i saw a setup on YT with a crazy looking tower filter over the whole intake mani/ITBs.
