Description

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
FXT 2 years ago
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.

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.

  • Q: 2015 STi fitment  jmray080529897 10 months ago

    Answer

    Can anyone confirm fitment on a 2015+ STi WITHOUT the Grimmspeed coupler/silicone kit?


    • 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.

    Answer

    Will changing this tmic require a tune for my 02 wrx.


    • 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

  • Q: Fitment for 2005 sti   mr_kris7787550 3 years ago

    Answer

    Thinking about getting this IC as and upgrade to my stock IC, wondering how the fitment would be wth regards to the stock hood scoop. Aka would it fit or would I need the grimmspeed spliter to run this IC? Also would be running a Borg Warner efr 6758 ar.65 would this be big enough to support this turbo?


    • A: This intercooler would be much more efficient using the Grimmspeed splitter. Also it would be a great match for a Borg 6758, anything bigger than that and you'll want to consider a front mount intercooler.
