Just got my 2010 WRX back 3 weeks ago after being rebuilt from suffering catastrophic engine failure, turbo seal went, lost oil, wifey drove almost 100km WITH NO OIL lol anyway planned on some work anyway so here we are now. Forged pistons installed, vf52, 3 inch dp, upgraded fuel pump, aos and Cobb AP. Running a stage 2 ots map with a couple minor tweaks to handle the slight difference from vf52. Works great, love the new pull but I'd like a little more. Definitely have a pro tune in the future but I want to finish collecting parts first as my ots map runs fine at its current state. I'll be upgrading my injectors (not sure of size yet maybe 850cc), Cobb intake with air box and probably a better intercooler when I pick one that's not too expensive but can handle slightly higher boost safely. When this car gets protuned I'm done modding until I go get an sti so my fellow subby enthusiasts who surely know more than I about building ejs, what else would you do? Sorry for the long post!
