would this work on our cars?

i have heard of people doing this, i dont see why it wouldnt work on our cars if it works on wrx's, as we have the same fueling system.

Can't say for certain that all the early FPRs are the same style as the new ones, but all the ones I've seen look the same. That's a neat trick.

down side is i cant find a pic of where to put the lil dent.

I'm assuming in the center of the regulator in the first picture of http://forums.nasioc.com/forums/showthread.php?t=928666

Between the word denso and the part number.

so if mine doesnt have a dent there thats where the dent goes when the time comes?

That was a wrx regulator pictured. It's different looking than ours to a degree. I don't think you should just dive into it, maybe you should have a backup first in case something goes wrong.

I'm skeptical of modifying something so crucial to the health of your engine. If something goes wrong, it could lean out super bad and burn up your valves and or pistons. The ej22ts have the same pressure valves as NA, but if you want a higher pressure one, the JDM turbo engines from the 90s have ones rated about 7psi higher stock.

can that be found on e bay ?

You may be able to get a set of jdm rails with one.

And yeah, ebay has some

sweet. trien to do budget mods on the subie. getting stuff here and there. few more parts and i'll be done

Why not spend the money to just get a Walbro or decent fuel pump? If you're not having any fueling or lean conditions there's no reason to do this.

If you do this "mod" on the FPR you will also affect the fuel pressure when not in boost, and that can affect fuel economy and possibly other drivability issues. I personally wouldn't suggest doing this.

i have a dw 200 in now and just saw this and read how others did this on the wrx's and wondered it would work on our cars

I've seen this before too. Sounds like a bad idea. It's right up there with turbocharing an NA engine without doing anything to upgrade your injectors or change your engine management to handle the extra fuel and maps.

That pump should be providing more than enough fuel for you. Just because someone does a mod doesn't necessarily make it a "good" mod. So unless you are experiencing fueling issues, I'd just keep this little nugget of information in the back of your mind if you have an issue in the future.

i think the new pump works to good lol the car seems a bit more peppy

The FPR trick really makes no sense when I read the thread. They want to get more headroom from their injectors, so they take a hammer to the FPR and risk running higher pressure than the pump will handle, then they have to retune for the change. Vs backing off the boost a hair, or just getting a set of injectors to handle their target power.

FWIW my ej20g and ej25d FRP looks exactly like the WRX one with the dimple.
