5psi, cheap as possable, here it goes...

Since aftermarket stuff is expensive, we're gonna go with some OEM stuff, which is a bit more work, but is cheaper...

WRX (or STI) exhaust the whole thing, manifold to muffler, with turbo
WRX (or STi) front crossmember and sway bar (to clear the exhaust) You can also just bend your stocker with a BFH, but this is not recommended.
Y-pipe, intercooler, BOV from WRX
Some sort of intake to the turbo

That's most of the major stuff, you'll also want some gauges to watch what's going on, (i'd recommend boost gauge, EGT, and wideband 02, but that's $$$). You'll also want something for fuel control, at 5lbs a RRFPR will do just fine. And a Manual Boost Controller to keep it at 5 lbs.

And all the various vacuum lines and whatnot you'll have to figure out on your own, as it's very hard to list them all.

 

hmm... would I have to get a TMIC? So basically, I can take all the turbo parts from a WRX and put them onto my 2.5?

 

What I want to do is take all the stock WRX turbo parts and put it onto my 2.5RS... is that possible and easy?

 

Possible...yes, Easy...not really.

99RS didn't come with a wideband 02 stock?

 

lol wut?

 

no clue, I might save up for the avo turbo kit. i think 250whp is worth it

 

I think its 265 CRANK HP so about 190-200 WHP.

 

sorry, that's what I meant.

 

avo kit? can I get it anywhere cheaper than $3500?

 

Swap it dude!!! Searching for answers here will yeald nothing!

 

Don't forget you need a smaller wastgate spring. And no stock car to my knowledge has ever came with a wideband 02. Definitely not a Subaru

 

Why go through all the trouble of wiring in 2.2 heads?!?! Just swap in an STi shortblock or rebuild your RS block with STi internals. That's what I did.

It takes a lot of work, and a lot of hidden costs that you'll run up on.

 

im fine with the power the AVO kit will produce with 6 psi... i didn't mention that this is my second car (senior in college) after owning a 140hp (if it's even that) integra from highschool. 260hp is cool with me... i'll be focusing more on the drivetrain/suspension but i just wanted to boost it w/o swapping or all those other costly/timey shinanigans. now someone find me an AVO kit for 1500 haha

 

Lots of cars come with stock widebands (Subarus included).

 

like what? (subaru)

 

STi, WRX. The front one is actually a "widband" the only problem is it isn't very accurate below about 11.0:1 from what I read.

 

Oh thats weird. My PLX sensor goes from 9.8 to 18. I think its a bosch too

 

Yeah the bosch sensors have a wider band.

 

yeah, you guys definitely got off topic...

 

:run:

Don't get the AVO kit, just save for a swap unless you really like tinkering. Especially on a daily driver

 

+1 Daily Driver needs a nice reliable WRX swap.
