I got the Acty purring like a kitten. I think it missed its 80Km maintenance before I bought it. So here is a list of what I replaced with part numbers: timing belt - Mitsuboshi HC2002 trans fluid: Motul 10w-40 water pump, idler pulley and tensioner - kit from ebay including timing belt oil/filter: 10w30 syn. (3 qts)/Micro T-61 thermostat: O’reilly 3758 alternator belt: Napa 3L280W antifreeze: 5l/5.3qts spark plugs: NGK BKR6E-11 front motor mount - ebay I couldn't have done it without this video: I added my lessons learned in the comments. My coolant reserve tank cracked where it had been exposed to the sun so I put a plastic bag in it. I hope it works and I hope this post helps!
