FA20DIT pulls hard, but plan on a maintenance sprint at 60k
2018 Subaru WRX Premium 6MT · 84,000 mi · 5 years, daily-driven
Pros
- Stage 1 tune transformed the part-throttle response
- AWD made winter commuting trivial
- Resale held shockingly well
Cons
- Rev-hang is real on stock tune
- RTV oil-pan seepage at 62k — caught it before it starved a bearing
- Insurance costs more than the payment
Bought it certified pre-owned with 21k miles. The first three years were uneventful — synthetic oil every 5k, OEM filter, 93 octane only. At 62k I noticed weeping along the oil-pan seam; pulled it, cleaned the RTV with brake clean, re-sealed with ThreeBond 1217H per the WRX Problems Guide. No issues since. Stage 1 tune at COBB Pro Tuner network, kept the stock TMIC. Dyno verified 268 → 308 whp.
