So in preparation for this new project of mine I've removed all of my rear mount turbo set up the only things left are the utec ecu which I will need and the fuel return system which is easier to leave than remove and will make no difference anyway.
as far as manifolds go I'm considering three options
1) make manifolds to mount straight to the heads like the obx/jenvey ones
2) make a manifold to fit to where the plenum does now like these
Yeah, the flanges would be CNC, but I figure I should be able to find the 40mm & 60mm stainless tube in pre-bent sections and straights and weld it up from that. Getting the 40mm tubes squared off to match the intake port shape is the bigger issue though.
The full piece:
I do have a 3D printer, but as the bed size is only 140x140, I think I will have to settle for a miniature of it for inspiration!
