    STi TMIC on WRX with samco I/C hose

    Spent an hour installing STI TMIC on WRX today. I will post a picture tomorrow.

    If you want to install STI TMIC with missing y-pipe (and use your WRX Samco hose), you will encounter two problems.

    1. Brackets will not align (on driver's side)
    2. Samco IC hose is about 1" short.

    Solutions:

    1. You will have to cut the Samco IC hose to extend the Samco IC hose. Use 1 7/8" OD coupler from Advance auto part to extend the length. I P&P'd the pipe to smooth out the edges.



    2. Longer Throttle body hose
    Intercooler to TB hose is about 67mm ID (too short @ 2" in length). You can order a 2.75" ID turbo hose (3" in length) from here if you decide to correctly mount both brackets. http://www.stylinmotors.com/turbohose.html



    ps: picture shown above has color matching turbo to IC hose. I bought it for $38 shipped from sylinmotors.com

    Update: YOU must get a JDM V7 STi splitter and shrould. USDM STi splitter and shroud WILL NOT WORK.

    Update: USDM STi air splitter and shroud kit WILL NOT WORK on 02-03 WRX with STi hood scoop. You must get a JDM V7 air splitter kit.

    How did you get the driver side bolt to line up with the bracket?
    I had to bend the pass side bracket to line up with the IC but the driver side looks like it has to be shortened in order to line up.

    FYI -

    passanger's side bracket mod:

    this is for a different intercooler, but same idea...



    ...and you can buy STi cast aluminum inlets with silicone hose for about $70 on ebay...just be careful when you cut the hose is VERY VERY easy to end up cutting off too much...I ruined 4 before I got it right.

    I'm not sure there would be a noticable difference. They're both way better than stock. I have the metal Y myself.

    If you are looking into replacing your OEM TMIC with USDM STi TMIC, make sure to replace air splitter kit with JDM one from rallispec ($84).

    I've been driving my car with regular WRX splitter for several months now and noticed TMIC was getting noticeably hot... I placed an order for a correct air splitter kit from rallispec yesterday finally.

    Finally had a chance to install JDM STi air splitter today.

    WRX splitter:

    Installed:




    Directs air through two channels (much more effective in cooling lower section of TMIC).
