So i've recently came across a good deal on a j32a3 with a 6speed tranny and a j35a4 odyssey engine.

I know the j35a4 have longer rods, different pistons and i think i read the J32a3 have bigger intake valves than the j35a4 (1mm bigger)

Im looking for straight suggestions on what combination should i used to make a faster engine. (Civic project)

which cam shaft should i use
which pistons
which rods
which cams

any info will be appreciated
