[s-cars] Wastegate to Frequency Valve hose

[Sean Douglas]

I looked onto this too as you are right, that's one expensive piece of
rubber. The hose is moulded and runs directly over the turbo takes a
bend then down to the WGFV. The last bend is almost 180 degrees and is a
tight radius. This is where you might run into trouble with a straight
hose and it may kink.

I suppose you could arrange a straight hose without such a tight bend
radius, but it would not follow the original path.

This silicone hose is rated up to 350F and is sold in 10 ft min length;

For $27, its worth a shot.
