I have an 84 242tic. My turbo is on its last leg and need to rebuild or replace and Im not sure which Garret turbo I have the plate is missing. If anyone can help I would greatly appreciate it. We used Vadis to look it up and they list 14 different turbos for that year. The only way they can tell which one I have is by the eng # they say is on the timing cover sticker. But it is an 84 there was no way that was still there so anywho... HELP. Now before I get posts "Just get a t3t4hybrid or 15g" thats not in the budget right now. But thanks.
