Indeed, engine wise not much different with normal car but maybe by shorter mileage due to turbocharger (fully synth only though). The tediuos part for evo is to service their transmission system which can be quite costly compare to normal cars. 4 item of transmission care required as follows:

1. SST GB - SSTF (rm600++)
2. Centre Diff - LSD Oil (example price for 2 liter kazz approx. rm200 - can be used for rear Diff also)
3. Rear Diff - LSD Oil
4. ACD & AYC system for Centre and Rear Diff require AYC oil or SP III (normally less then rm100)

The parts only require close to rm1000 for evo X, some reputable workshop really overcharge the labor cost. need to choose wisely.

But this transmission service require for 20k km interval or shorter and it will be cheaper in cost if you opt for manual GB evo due to much2 cheaper normal gear oil.
