[Es2] RS2/ES2 intake & exhaust source/fabrication

[Matt twentyV]

I'm running a stock 200Q20V turbo intake boot/ hose.  With this you can't use the WGFV in the stock location as it interferes with the support upright.  I've used a very short length of pipe to move it below the boot.  Attaining full boost is very sensitive to this plumbing- a long hose caused me to lose boost.  It took me a while to figure this out- we temporarilly used a stiffer WG spring to restore full boost but that bugged me so I puzzled over it until eventually stumbling on this sensitivity.

The turbo outlet to intercooler (RS2) hose was sourced by 2Bennett, I'm not sure if it is a standard 200Q20V samco equivalent- it looks like it might be but YMMV.

Intercooler to intake (3B) is a custom metal pipe and the standard 200Q20V accordian hose.
