I have read in several places that the coolant ports on a Geo Storm throttle body are useless. I picked TB from a JY, cut out the butterfly plate shaft, ported it, made a butterfly plate by hand, welded the shaft back together and then drilled out the coolant lines. I then drilled at an angle into the TB behind the butterfly plate to match the setup on the SC1 TB. I installed vacuum line elbow connectors into the coolant line cavities and ran vacuum line from the elbows into the TB. I then cut the lines flush inside the the TB and connected the 2 vacuum lines the same way they were on the SC1 TB. Works like a charm.
