ok, so a buddy of mine is looking to pick up a 1994 dx coupe for a bandit. Car is race ready stripped with roll cage and everything.We're looking to get the most power for the cheapest buck, with no after market parts. No VTEC and I'm looking for an si tranny The bore is the same as a d16a6 but the deck height is shorter, could I be able to throw p-29 pistons in there (88-89 teg) to up the compression?. just gotta use stock rods? Run a d16z6 head gasket for a compression boost? The d16a6(pm3) and d15b7(pm9) head specs match up, so do they perform the same? Would it just be better to throw a si/zc cam in there? Fuel Control : OBD-1 MPFI with a big mole, whats a big mole?
