Its funny because youll probably find more forums (Like on reddit) about guys tuning the CVT in the 2020 XT's and above, but when it comes to a WRX, dudes be like "Nope" lol. People have opted for the JB4 as far as what I have seen on the Outback XTs. IF you do, go for something like that, I would advise a "Light" tune; at least before someone blows their 2.4 up and we can clearly see the tolerances of the trans. Outback XT has a higher torque rating due to its 6 Spd Auto config. WRX supposedly runs an 8spd config in the SPT. Only the WRX has the SPT trans.

Can you make a second thread with all of your experience using the JB4 on the outback? How does it feel? Perform? Any abnormalities within these last two oil changes? Transmission still behave the same since first buying?

I logged all of my JB4 journey in the Outback forum thread But in summary, JB4 has done really well and zero transmission problems. Donít hook up the electric wastegate port for the JB4 because it caused my wastegate arm to seize, resulting in zero boost and P003A code. I was able to unjam it with a screwdriver but there was one person that wasnít able to unjam it and he needed a whole new turbo

Engine is absolutely solid! Beefier rods and direct injection means detonation/ringland problems in the EJs and bent rods in the FA20DITs are a thing of the past. 2.4L twin scroll turbo is a blast with instant torque augmented further with mods. Itís more than enough driving on public roads

Also Terry and Canon on the burgermotorsport forums are very responsive and helpful

The Outback XT is rated to tow 3500lbs so the transmission (now with OEM cooler) should be able to handle +60wtq
