    yea, i wasn't sure if people had already done this or what, but i was expecting more replies. So far so good though: No cel's, spools up alot faster, and there was a very noticable top end improvement. The turbo noise and stock BOV are more pronounced but thats to be expected, and i love it.
    I can't say that my EGT's really changed too much either: max before was 1425 at the top of 4th, and i was at 1400 at 5k before i had to slow down but i know it would have gotten hotter if i wound it out more.( This is 3" off of the head on #4: kinda rich i know...)
    I will say though that i'm not happy with the bracket i made. I need to make something a little more substantial because it doesnt sag or anything but it kinda moves back and forth. I think a GPMoto or Samco elbow might help with that some as well...

    Man I can't believe I paid $125 for an intake when that is all that is needed! Had to fabricate a bracket from some metal strip too and then zip tie the intake to the metal strip...

    On my fmic install, I was kinda pressed to do it. I had it at a friend's house for the install, by the time I was putting everything back together, it was too late to go find an intake @ a shop, and I had to get it running that night so my boy had a barely used K&N so I said wtf, why not

    i did this about 2 weeks ago. best free mod ever. well free for me since i took the cone filter off a friends old crashed car.
    it took about an hour to complete and there was no CEL. the turbo has signifigantly improved with the spool time and it is loud as hell.

    so overall it was a very good "free" mod

    What filter did you use?

    Can this be attached right at the turbo inlet pipe or do you have to use that curvy currogated piece?

    I used a K&N filter (p# RX-4990) because unlike most filters, the inlet is actually radiused. Any 3" conical filter should work though... to an extent.

    I guess you could join the short ram portion right to the inlet pipe (you'd still need a piece to join them though) but why? That just brings the filter closer to the engine so it can take hotter air. Another issue whould be the MAF and if it would reach. Regardless I wouldn't recommend it.

    May I ask whereyou bought it from and how much? Im looking online and so far $60 is the best price Ive seen. Anything cheaper? Im most likely going to buy an airbox off a friend and hack it up just so I dont have to hack up my only one and screw it up.

    I got it kind of spur of the moment at a local speed shop... 10 minutes and $75 later I walked out with a filter. Originally I was going to try to use an APC filter I got from Autozone but quickly returned after looking at/buying the K&N filter. You really get what you pay for. I'm not saying its the best, end all filter I'm just saying it works great for me.
