I would go to Flynmiata and get the tb adapter, the coil pack bracket and the cable bracket, the rest is not really needed. Its just like a reqular engine install, just different block. Also get a new waterpump and timing belt. Timing is a breeze, no sweat.
The few things that you will need that delayed my install are:
the o-ring that goes on the water outlet pipe off of the 1.6, Buy one from a Mazda dealer, the local parts store do not have the correct size. You then reinstall it on the 1.8 Block.
The exahust is different. I was told that the cadalitic converter was the same, THEY ARE NOT. YOu'll need the exahust from head to tip, IMHO.
Because the engine is longer you'll have to (at least I did) "modify" the passenger side fan to make it fit aroung the intake tube that goes in front of the engine.
K&N filter, stock air box may work.
I'll ask Monkey when he gets in if I left any thing out.
The swap is NOT hard.
