2006 WRX TR

Default MZWRX's 2006 WRX TR

This is my 2006 Subaru Impreza WRX TR. I have owned this car since July of 2010 and it is absolutely my baby but I've never really felt like it deserved a thread in this section until now. I've learned a lot over the last (almost) 7 years and I feel like its time to share some of that knowledge.

The quick version is that its significantly modified WRX with an autocross focus done by a mechanical engineer with an attention to detail. Its now got a freshly built 9.7:1 compression motor and a Blouch 18g-xt. The car peaked at 350whp and 356wtq (on separate pulls) with a 7500 redline on its best runs, but the knock free(ish) map/pull made 333/353 on the dyno. It balls pretty hard from 4000 - 7000 and scoots along at 20 psi of boost, which for autocross is exactly what I wanted. I'll post the whole build list below for anyone who actually wants to read it.

I have years and GB's full of pictures but I'll spare you all the history lesson and just share some of my favorite pictures from the last year or so, Enjoy!

Dyno Day:

Final Dyno Plot, look at the green values, those are the numbers for the map we settled on

And finally an Autocross Slide

And for those who care a mod list, after putting it all in I realize this is no where near complete.

Thanks Subie22. I just finished the build and tune about a week ago. I'm hoping to make it through all summer with the transmission but we'll see.
