Generally it's a good idea to upgrade. Stock injectors won't be able to put the extra fuel you are pumping to good use. If you do upgrade the injectors, you will need a retune, either DSMlink, or a piggyback system like SAFC.
 
My car came with an older APEXi afc, I just dont know how it works:confused:. I got the car off some guy who knew less about the car than I did, so he can't help me. I do plan on upgrading the unit asap, but I'm kinda limited on the funds. I would just like to get it streetable until then, without causing any damage.
 
i'd put the 255 walbro in including a rewiring kit, get an afpr. then after get some bigger injectors so you can really kick in more boost to it. i don't know what turbo you're currently running but i'd suggest get one if you can then it'll bring you a pretty decent amount of power to it. with your apexi afc you can do much to it for a streetable dsm...you might want to think about down pipe exhaust if you don't have one
 
For now, the pump, AFPR, and rewire (you can buy the rewire parts at Radio Shack for pretty cheap...wire, relay, fusible link, connectors) will get you started. You can run stock injectors with all of that.

Get a logger before you do much to this car. A common option is an old Palm off of eBay and an "interface" or cable to connect the palm to your diagnostic port. You can buy the interface or make your own. The logger will tell you if you're leaning out, knocking, can read diagnostic trouble codes, etc. That will come in handy when you start tuning or increasing boost past stock levels. You also need an aftermarket boost gauge if you don't already have one.

If you don't have an MBC/EBC, you can increase boost a bit on that FP/AFPR and get more out of the turbo. Is it an A/T or M/T? A/T has a 13g turbo (very small) while the M/T cars have 14bs which are the best of all the 1g/2g stock turbos. You can't get as much out of the 13g as the 14b, but you can get more out of either than stock. Make sure you have a logger before you start increasing boost.

Of course, before you increase boost, get the car in good shape. Boost leak test, compression test, change fluids if you haven't already, and check the turbo for excessive shaft play and oil leaks. If the PO had any maintenance records, check them out. Those sorts of thing.

After you get things working well, you can start tinkering with the AFC. The piggyback tuning guide will hopefully give you a basic idea of what you have to do and why. Since you have it, you could upgrade the injectors a bit and then push the boost even further. That will certainly educate you on the basics of tuning. As funds permit, you can certianly do better than an AFC, but by then, you'll know all about that.

Good luck and have fun!

What are you refering to when you say,"re-wire"? Are you talking about an install kit for the pump, or does it have to do with my afc?

I was talking about a fuel pump rewire. The stock wiring uses very small wiring. The rewire bypasses that wiring with larger gauge wire and uses the stock wiring as a signal for a relay. I don't know anything about rewiring a 1g, but on a 2g, the only signs in the engine bay will be another wire off the battery, but if you pull the 2g back seat, you'd see the relay next to the pump. I imagine it would be similarly hidden on a 1g. But if you look into rewiring a 1g, you'd probably then know what to look for.
