fuel system q??

[deftonesfan7]

Howdy, wondering if you all can point me in a general direction. Im looking to move up in the power and I believe next is a new fuel system. Im looking to get about 350-400 out of my car. I need a pump, rails and injectors. Where can I find a place that sells all of this? Any sites or pointers would be greatly appreciated. Thanks.

BTW: I am at stage 2 right now, exhaust and EM is all I got. Im thinking of doing fuel and intake at the same time, then I just have to decide on a front mount or a top mount then just the powerhouse(turbo) left.

Thanks for all the help!!

There is no need for fuel rails at 350-400 hp. As for the fuel pump you can pick up about anywhere for about $90-100. As for injectors, you can spend 300-500 for some new one's or you can get your stockers modded for about $100.

The intake is not needed unless you really want it. I was also told that rails aren't needed either. Walbro 255 is perfect for anything you're trying to do. You can send your injectors into a company and they can bring them up to whatever size you need.

Pump $89

geez...great minds think alike

Yes they do tom! your stock intake will hold unitll about 300awhp, all you should need is a good drop in filter and maybe a silencer delete. If not I would look into a spt or cobb short ram intake.

so why no rails? i heard that the #3 silincer runs lean? but you think that just a pump and injectors would be good? what size injectors is ideal?

jdm sti fuel rails do not. Get them used for cheep. Plus your tuner should tell on if it really is neccessary. The majority does not experience problems because of fuel rails.

Well injectors kind of depend on what turbo you are going for. If you get your stockers modded, I have seen them around the 800cc area. That should be more than enough.

[wrxman420]

Just as newtothegame said it all depends on what turbo you go with. Witch Hunter told me they can mod 06+ top feed injectors up to 920cc.

[newtothegame]

Holy crap, that should suffice for just about anything anyone is looking for there. How much would it cost for that wrxman420?

[wrxman420]

The last time I checked it was $108 with shipping. Keep in mind 920cc is only for 06+ wrx top feeds (dark blue's), the light blue injectors (02-05) can get modded up to 820cc i believe.
