Any reason not to upgrade rods/pistons besides money concerns? I had a 2013 WRX as of a month ago before I totaled it and if your goal is a reliable DD, I would also recommend getting new clutch and flywheel. I had an Exedy Stage 1 that slipped after 19k miles, according to Exedy Performance division, resurfacing my old flywheel wasn't sufficient and I needed a new flywheel while upgrading to the Exedy Stage 1 clutch. I only chose this clutch because I dislike puck style clutches and i've had 2 different ones in my 670rwhp Mustang and could not stand them for drive-ability reasons. Unless you have the money to spend on a twin-disc.

Also, with the EBCS installation will need a tune, get a professional one, not canned. It'll cost you the usual $500 about, but is absolutely necessary.

Here are the mods I had on my 2013 WRX...

Perrin CAI
Perrin Turbo Inlet hose
Perrin Catted DP
Turbo XS C/B
Perrin Turbo Heat-shield
DEI Titanium exhaust wrap around the DP
DEI Reflect-a-Gold partially wrapped on the TMIC
Cobb AP V2
TurboSmart BPV
Grimmspeed EBCS
NGK Iridium Plugs (1-step colder)
Deatschwerks DW65c Fuel Pump

Tuned by Agile Auto. Made 308/339 @20.5lbs on 93.

Exedy Stage 1 Clutch Kit
Kartboy Short Throw Shifter

Radio is the European Model which is basically just a small LCD screen that lights up "Subaru" when you turn on the car and its easier to rear which song is playing. Still works with the factory BT and steering wheel mounts.
I have the A-Pillars and the Panel that covers the Radio in Alcantera which I did my myself and used 3M Super 77 Adhesive to make it stick, plus you need a bunch of clips and a heat gun to smooth any wrinkles out.

I am not going for big enough power to justify changing the internals, and from everyone I’ve spoken to it doesn’t make sense at my power levels and will likely make for less reliability, not more.

We also already have an ACT clutch and flywheel thankfully. Also picked up an IAG “street” AOS this week. We also got our vf52 back from the shop after being rebuilt this week.
