The GReddy kit is a good street setup, but I'm not too sure about RAZO. The only time I ever went in there I got quoted some rediculously high prices and I also think they do their installs either in the parking lot or in the back alley. If you get a GReddy kit, the simplest way to get it ready to run 6-8lbs of boost daily is to ditch the GReddy box that's supposed to trick the ECM into not seeing boost, and replace it with either (fish tank)check valves, or a Missing Link aluminum check valve. The GReddy kit also comes with a 12:1 FMU, but no inline pump which means you'll need to add an inline pump if you want to turn up the boost, or else you'll lean out.

Just the addition of an inline pump and check valves will make you pretty much ready for 6-8lbs of boost, but you'll be running pretty rich with the FMU setup, so in order to tune it, you'd need some way to trim fuel under boost. Something like an AFC or SFC would be good.

Of course, if you're planning on running the DSM's, you would ditch the FMU entirely, and you wouldn't need check valves either. You would just need an AFC, and maybe a Walbro intank pump if you want(not totally necessary). In order to wire up the DSMs, you would need a resistor box out of an older Accord or a CRX(any Honda with peak-and-hold injectors), as well as the injector clips to match your DSMs. If you can't find, or don't want to buy a resistor box, you can wire 7-8 ohm resistors into the injectors harnesses. As for places to get DSM 450s, dsmtrader.com is a prime resource. For the resistor box, you can usually find them on eBay, or The Parts Trader.

As for tuning, it's hard to tune perfectly without getting it on a dyno. If you plan on running the AFC with the 450s, your base settings are going to be -40% across the board, which runs and idles fine, but you'll need to fine tune it on a dyno with a wideband O2 sensor to get the best power.
