Features & Product Details

When it comes to selecting the right intercooler with maximum cooling and minimum restriction, then check out this GrimmSpeed unit. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because when they’re compressed, the atoms in the air are forced closer together and as a result, move faster and have more energy. That energy manifests itself as heat. The more heat we can remove from the system, the denser the air becomes and that’s what helps eliminate pre-detonation, or ‘knock’, allowing for increased output from your system. Your OEM TMIC does just fine at stock boost under normal use, but as soon as you start putting some real heat into it with higher boost or harder use, it heat-soaks beyond recovery.

These units have been engineered to find that perfect balance with heat transfer and pressure drop. They began by laser scanning an OEM TMIC to plot the mounting points and space claim in CAD with pinpoint accuracy. At the same time, they designed a custom bar and plate core with overall dimensions, fin density and fin types that would provide the insane heat transfer area they require with minimal flow restriction. With core size nailed down, they got to work designing end tanks that offered smooth flow, perfect fitment and even distribution of the hot charge air through the core. Countless revisions were tested in flow simulation before they finally found exactly the characteristics that they wanted. From there, 3D printed prototypes were used to confirm fitment and we began work on manufacturing details in preparation for verification testing and production.

Each and every end tank is cast from the same CNC machined mold, ensuring not just dimensionally perfect castings with an amazing surface finish, but also excellent repeatability. They designed tabs to be laser cut and CNC bent from 5052 aluminum, selected for its ductile nature, to ensure that the bending and welding processes don’t compromise their integrity. And this will allow for stock TMIC bushings. These are also designed to work with your stock y-pipe. Of course if you don't have one they've also designed a cast aluminum y-pipe kit with a 4-piece 5-ply silicone couplers and t-bolt clamps for each connection.

04-05 Forester XT require a STI BOV and STI BOV recirculation hose.

WRX and Forester models will need OEM STI or GrimmSpeed Y-Pipe Kit

Replaced my OEM TMIC with Grimmspeed. Well built an looks good. Its moderately heavy and a pain to install since your semi leaned over. Fitment is tight. Item was well packaged an shipped quickly. Pleasure doing business with RSD again.

GrimmSpeed Top Mount Intercooler on 04 Forester XT 2 years ago
FXT
The unit it self is great. The only issue I had was the lack of info about the installation. Some people said that you can still use the OEM Y pipe, but if want to save time and pain, use a silicon after market Y pipe.

Very nice intercooler, such beauty, much wow. 2 years ago
Taylor W.
I replaced my 02 WRX intercooler with this guy and all went well. It came in a well packaged box that included all gaskets (3) and hardware for my bypass valve and back side y pipe fittings. Honestly, I had this installed in under an hour with another manufactures y pipe kit (I was a silicon based kit) and all fitment was good. I don't have a WRX chassis so I was a bit concerned about fitment with the hood scoop but all clears, just make sure the hardware from you scoop isn't long enough to poke the fins a bit as mine did, its much taller than the stock one. Performance is good, I need to check a couple more fittings for any boost leak issues but I did notice a slight drop in peak psi for boost. I attribute this to the much larger space for the air to cool. Noticeably more power in the pedal and sounds slightly more throaty now. All in all a great product.

QUESTIONS & ANSWERS

  • Q: Upgrades on a 2006 Subaru WRX  Jacob 4 months ago

    Would this be enough for a blouch tdo6-20gxt turbo. I will be getting new 1050 injectors, 255 pump, cosworth air intake, turbosmart bov, boost solenoid, and a grimmspeed exhaust. Is there anything else I need to prevent engine implosion?
    • 0 of 0 people found the following answer helpful

      A:  This would be a great TMIC for your setup. Although a 20G is approaching what most would call the safety limit with the stock block, a good tune, an air oil separator, upgraded oil pickup and baffle, aluminum radiator, and good maintenance are all great steps towards making your motor last.

      A:  We only recommend using GrimmSpeed's Y pipe kit as it has been confirmed to fit. https://www.rallysportdirect.com/part/intercooler-hose-kits/090096-grimmspeed-tmic-y-pipe-kit-black

  • Q: 2015 STi fitment  jmray0805298971 year ago

    Can anyone confirm fitment on a 2015+ STi WITHOUT the Grimmspeed coupler/silicone kit?
    • 0 of 0 people found the following answer helpful

      A:  You are going to need a y pipe for this intercooler. The Grimmspeed kit is one we recommend to use but it will work with other y pipe kits.

    Will changing this tmic require a tune for my 02 wrx.
    • 0 of 0 people found the following answer helpful

      A:  While you don't need to a re-tune to run the TMIC, to get the most power out of it a re-tune would be recommended. -Andy
