Default need help/comfirmation

alright i've done some searching and havn't really found any definate answers. i am looking for someone to help ease my worries. i'm running an ej22 turbo short block with rs heads in my 2000 rs. the original rs engine the shortblock was installed on was out of a 2002 rs. i hav RC750cc injectors. there are some fitment issues, rails don't fit the tops very well, o-rings don't fit top or bottom very well, air assist rail is a pain in the butt. but everything is able to be dealt with for now. i'm bringing the car back to school with me for an engine overhaul class and it'll b apart again in no time. when its apart i would like to replace the intake manifold with a non air assist manifold so that the injectors fit better down in the injector bore.

this brings me to the obvious solution of a 99 manifold. now for confirmation, will my RC's fit the 99 manifold without machine work. i think they will from what i read.

another question. i know perrin has fuel rails for the wrx and sti, does anyone know if the wrx perrin rails will fit my RC's and the 99 manifold? if not then does anyone hav any recommendations as to a manifold, fuel rail combo that will be a better route.
i'm running an svx fpr with duel inlet so thats taken care of for the parallel, and if perrin fits (please) then that already has a nasty ss line parallel line setup. so any info would b great. thanks guys and gals.

perrin fuel rails will not fit the 99 manifold without fabrication. BUT fabrication is easy, a matter of making some plates (as my machinist friend is on my APS fuel rails)

nice, could you let me know wut exactly is needed for fabrication? i goto an auto school and hav a full machine shop at my disposal and could easily hav things made for rails. also wut injectors are u running? if yru running RC and you can confirm that aps rails will fit the tops of the RC's then i'm golden. how do you like the aps? are they similar to the perrin? i just wana get a good set of aftermarket rails that come with a stainless line parallel in and out setup already integrated. thanks for the response.

I don't think the RCs will work with the perrins or aps.. what is the diameter of the RC injector fuel inlet without an O ring. the WRX stock ones are "just" fit with a tiny o ring... i don't think it will work... but making the hole bigger should be no big deal for a machinist...

I am using WRX cut caps and STI pinks... (currently pinks) the plate that fixes the rail to the manifold is too short and the bolt holes are too far apart...

I don't want to respond to fuel rail questions because after seeing these rails in person i'm totally bious...
