I have a mechanic that normally works on performance cars but when I did the downpipe exhaust and a revo tune at 10 k the clutch started slipping and he agreed to do a spec clutch.Since then I’ve been able to do my own maintenance. But I’m now at 62 k and still love the car so I’m going with the $400 ECS kit that he says is a full day. My question is should I do the alternator and water pump and is there anything else that I should replace.?
