I'm turboing my 2000 2.5RS and i'm kinda new to this so any help is good...I'm using a turbo from a Silva S15 my friend used it in his legacy and ran 12-14 pounds and put about 300 to the wheels but thats a different story he had a whole bunch of other stuff...but i need help finding a down-pipe and i was wondering what down-pipe i could use like a WRX OEM downpipe and where i could get one and a new wastegate so that i can set it from anywhere to 6-10psi...to go along with this i have Borla Headers from which i heard people who have turbo'd their RS's is fine...I'm using the Greddy Evo Exhaust right now hopefully it can still be used...I have the WRX intercooler which i heard is fine and a legacy oil pan with the oil lines already set...i'm also using a Stage 2 Clutchmasters clutch with fidonza flywheel figuring the stock clutch will go soon anyways....I need to know if WRX injectors will fit...as well as anyone have feedback on the Walbro 255lph fuel pump...the Apex'i Boost controller with HKS turbo timer...just wondering what you thought of this setup and any other tips...and i don't want a EJ20 swap i know its easier to work on but i've been in a Turbo 2.5RS and a worked WRX both quick but the torque in the RS-T was insane throw yourself back type of sh*t

you are going to need stronger internals to do any type of good boost on the stock ej25.

O ya i know that but for now i just wanna run like 6-8 cuz the internals aren't rated past 10....maybe later on get the short block of the EJ22t or EJ257 on there to run higher boost

It should be pretty easy for you to contact a current WRX owner about getting an OEM downpipe. I've never dealt with a turbo on an RS but you could contact these guys http://www.gruppe-s.com/Contact/about_us.htm and I'm sure they'll be able to get you everything you need.
