I'm a new guy here and need your help changing the timing belt on a '93 DOHC.
Any advice is welcomed, but here are a few things I really need to know.

What else needs or should be changed when it's opened up? (seals, tensioner, etc)

Is there room to easily do the change? (What needs to come off? It looks tight to me)

Where do you guys buy parts? (Is OE Mazda worth it?)

Thanks. I'm looking forward to this board.

 

You should change the timing belt and the tensioner pulley. While you're at it check the powersteering and alternator belts Replace them if they look questionable,.

The OE timing belt is tha shiznit. You should have no problems with it.Mine was only like 30 bucks or so. I'm not sure how much the tensioner was though.

I changed a timing belt on a first gen before however it was back in highschool like 7 years ago. I don't remember exactly what needed to come off though I do recall that I took the front passenger tire off and pulled some of the plastic sheilding from inside the wheel well and that helped an awful lot.
