TB Coolant Crossover/Bypass, Any Disadvantages? - ZR-1 Net Registry Forums

It appears that there are six threaded plugs we are talking about to eliminate ALL the hoses (including coolant bypass hose) all the way back to tank. Four on the plenum and two on injector housings. They all look like 1/8 inch pipe thread to me....is that correct? I assume you simply cut off the existing hose fitting and drill the remainder of the fitting out of the plenum tapping with 1/8 inch pipe tap.

Simply cap off the bypass hose at the tank as Ccmano says eliminating that TB bypass hose going from "T" on passenger side of engine to tank also.
