OK i searched and could find nothing.. i need to know where you could buy aftermarket performance internals for my 98 HX.. im looking for pistons, rods etc.. thanks for the help..

 

Any bottom end components from a 92-00 Civic 1.6L (D16Z6 or D16Y8...civic EX models) will work.

There are no mass-produced aftermarket head components however. I would upgrade to a D16Y8 or even a B-series if you have the cash, they have much more aftermarket support.
