next for turbe ex
i just got my car back from the shop!!.. to refresh you memory i got a '97 turbo ex (sohc vtec) d16y8.. Tubonetics wastegate, hks manifold, garret t3, turbo xs type h BOV, intercooler, .. and i was just wanting to know what you guys think the next upgrade should be??.. everybody i've talked to so far says fuel... and so i ask what about it??. .. fuel injectors?, fuel rail,?? teach me the ways of good fuel for my turbo car...!!!

You want to upgrade the fuel pump, definitely.
You also want to upgrade to higher flow rate fuel injectors. You can either get some RC 440 cc/min, or get used ones out of a turbo DSM for pretty cheap. To run the DSM injectors you'll need the injector harness and resistor box out of a non-OBD ('88-'91) 4-cylinder Honda.
From there you'll need a way to tune the thing. You can run an A'PEXi V-AFC with no sort of "hacks" by setting the fuel trim to around -35% across the board and then drive it to a dyno for tuning. That'll run like $300 plus tuning time.
Otherwise there is Hondata. An s100 w/ boost will run you $445. You will need to accquire an OBD-I ('92-'95) ECU preferably out of a VTEC car for Hondata to convert, and a harness to plug the OBD-I ECU into your OBD-II wiring.

The non-OBD Honda injectors have a much higher impedance (like 12 ohms I believe) than the newer ones which are like 3-4 ohms. The DSM injectors have similar impedance to the non-OBD Honda ones so you need a non-OBD Honda resistor box to match the resistance to the ECU.

Actually, it's the other way around. Saturated injectors are high-impedance, and you need the resistor pack to make up for the peak-and-hold injectors' low-impedance. An ECM that was meant to run saturated injectors will be looking for that 10-12ohm impedance.
