thinking about the construction of a turbo manifold for my CA18DET has been bouncing around my head, i want to go do a welding course and make the dam thing myself, i know how i would cut the pipe to make the collector, how the pipes would bend, everything.... i have made mock ups on the computer, even in 3d.
ok so i was BORED, really bored, last night, 2 rolls of toilet paper, one bounty roll and some masking tape later i made what you see here...
the rolls are ~1 5/8" ithink, about the port size of a CA18, now i can just rip it apart and measure the angles, make masks of the cut areas and get the measurements for the collector...
ok maybe not

i think i better go do the welding coure first.. but i will finish the cardboard manifold of course!
