Motor Building Questions???

[20035mazdaspeed]

I am thinking about building my motor but just wanna know what all is recommended during a build? (obviously rods and pistons). But should i stay at stock bore or go to 20 over? And what bearings and things to replace? I wanna do it right and complete the first time instead of do it twice...Thanks in advance.

New water pump, oil pump, timing belt and tensioner, main, thrust and rod bearings, full gasket set. Oil squirters are reccomended.

As long as the cylinder walls aren't scored, you can use stock bore pistons. Overbore pistons can be used if you want to increase displacement a little bit or if the walls are damaged.
