accumulators were installed on the oil cooled side of the turbos. the idea is to fill the accum. while running, then after shut off, the accum. empties the cold oil past the hot turbo. this was not part of the turbo plus package. i forget exactly what was in the turbo+ kit. the box was a little bigger than a radio box and had a harness and some other stuff, i think a new brain, too. been a looong time. hopefully, dick in falls church will see this and jump in. he knows far better than i do. good luck, chuck.
