This is an 87-88 stage 3 turbo. There is a medium puck and a large puck. The medium puck goes on a stage 1 and 2 and the large puck comes on a stage 3 and 4. The port is taperd to the exhaust for more flow and the puck swing arm was increased by 1/4".

I thought this was rather nice, it is ported bigger than mine.
