02 Housing
i know alot of guys here in NC that are using it and they've used everyone thats out there. buschur, ebay o2, megan, etc. and they said works is the best out there. very expensive but they say its the best and it also allows the stock heatshield to bolt up to it for a "stealthy"/stock like look. u can't even tell its in there. if u get the 10.5 hotside for the 03 stock turbo and add WORKS o2 you'll definately see a nice difference in your car. of course, a good tune to go with it. i'm guessing u'll see a 15-25whp difference with those 2 together depending on the tune and fuel being used.

i'd say 25whp for the 2 of them @ $700 is a good investment for performance. i'm assuming u already have a 3" tbe to go with them. if not, i'd definately invest in a tbe also and a megan 3" tbe only cost $545 shipped from zeus, which i have also. you'll see a very very nice improvement with those 3 mods together. do a TTM flash and you'll be good to go! good luck.

I have the Works TR-340 package, so this would hopefully improve power. Maybe thinking about upgrading the injecotors and fuel pump to up the boost to 21 psi after these mods.

Yes.
As mentioned, since you're doing the hotside, now would be the perfect opportunity to add the WORKS O2 housing as there really wouldn't be any additional labor now and you'd be doing virtually the same job twice if you add it in the future.
i've seen this part on 4 evos here in nc, combined with different mods. all have at least the 10.5 hotside, WORKS O2 housing and their DP and i'm very impressed the difference these 3 mods make. great products WORKS!
