We get many calls for upgrades on this model, as a guide to assist you we have created this list to save your time, guarantee your money is invested correctly and most of all give you maximum value!.

SUMMARY
Typically this car in Australia is “Mitsubishis detuned EVO engine”, it was, is the last of the real EVO’s and dramatically different to all before it.
There are some great features of this car, 4wd, turbo, 6 speed auto and most of all, a sensible budget with some well planned upgrades and it turns a great car into a great super car beater!

ECU
(All Australian and Japanese models)
Can be converted and fully tuned, using EcuteK Software for almost any improvement, and allows solid results with correct settings and allows good improvement.
If the car has been run on the wrong fuel (jap models are tuned for 100 Ron) then the ECU will have detuned it more and a retune on 98 will make more power, more reliably.
Dont under estimate the incredible improvement with a good ECU retune.
more info here on an EcuteK Factory ECU upgrade for the Mitsubishi Lancer RalliArt

ENGINE WEAKNESS’s
Bottom end and mid range performance can be dramatically improved with ECU tune. The engine is dramatically detuned by Mitsubishi and also power limited due to emisions requirements when delivered by the factory.
Poor boost control with the factory standard settings can be annoying.
Boost maps, can be improved.
Complete new engine compared to previous EVO;s. Has no timing belt, (is a chain)
(Engine has VVT cams like EVO 9 model)
Car should be run on 98 Ron Fuel unless a custom (ecuteK) map is done.
The factory turbo is reliable, but if over boosted with boost controllers etc will result in wasted power and an indirect effect on poor ignition.
Turbo, air intake, and such all are different to EVO.

ENGINE SENSORS
On this model the aif flow meter sensor is very reliable
Depending on model, Jap spec or Oz the twin rear exhaust O2 sensors if located incorectly related to modified exhaust can cause problems, if old can also dull the cruise performance of the car and increase fuel use.
Crank, cam  and Knock sensors are reliable, but with age can fail.

INTERCEPTOR ECU OPTION
Not worth considering as the intercptors simply do not have enough options to tune and modify the latest technoplogy control inputs.
ZERO VALUE

NEW (replacement) ECU
Factory ECU retune is best value unless a really serious engine rebuild is chosen.
See notes above

INTERCOOLER
Factory fitted unit is “OK”, dont fit a replacement FRONT mount unless you have a HUGE budget and a BIG engine upgrade
Only fit a new FMIC after a MRT XC power kit.

INJECTORS
Bigger injectors empty your wallet and add no power unless part of a E85 fuel retune or major engine rebuild.
Save your $$ for suspension and get some GOOD improvements.
OEM Injectors are big enough unless you do a major engine rebuild.

FUEL PUMP
More than adequate up to 60kw at the wheels after that a 500 hp pump can be retofitted

EXHAUST
(Some traps for people here, unless carefully chosen.)
Turbo engine pipes with collector to fit wastegate will help marginally, but costly to fit and will add some throttle response.
High flow ceramic or better, a metal cat in the downpipe is best.
A factory Flex joint back exhaust (with a newer larger diameter flex joint) is best value, with correctly located O2 sensor.
Get this wrong and the car will suffer CEL lights, and cause poor fuel economy.
The rear muffler adds no value in just replacing it and should be completed as a part of a whole “flex back” exhaust kit..

AIR INTAKE
Other than a intake noise no power here.
A replacement panel filter in the std airbox will save on future servicing but give no power improvement.

ENGINE ANCILLIARIES
Items such as aftermarket plug leads, high capacity discharge ignition systems etc all will ad very marginal if any improvement.
A GFB alloy crank pully is available and will result in snapp/ier throttle response.

TURBO
If you have the budget a (bigger) turbo upgrade will add (peak) power, but be careful the OEM turbo is best only changed as part of a kit (like the MRT XC kit package) and is best kept in place unless you have the right other parts to match a new turbo upgrade
As the limit becomes close to the engine needing other supporting parts such as larger injectors and results in a peaky power outputand will give no value unless you plan carefully.
(meaning if you fit a bigger turbo you can use its benefits but be careful as the extra boost will need to be tuned carefully )
If you want big grunt and big torque then ok, this is an option here, then you need to plan a engine rebuild or be wary of the resulting load on the engine.

ENGINE INTERNAL
Like above if you have a solid budget, then a rebuild will give some great and huge benefits, the engine is a very very good package and flows great HP and is very tough. A rebuild will cost over $7k and then you need to choose carefully there are many options, but only if you REALLY want to.
Conrods will fail over a certain boost threshold so choose wisely, Aftermarket head like Cosworth will add value if you have big turbo and manjor mods.

OTHER OPTIONS
Is the car serviced correctly? Because often a service by a workshop who really knows Mitsubishi’s will be your best choice for first place for power and reliability.

IE:

  • Upper engine cleaner and in tank fuel additive. (when was this last done, as often the Jap import cars have huge carbon build up).
  • Good quality low friction engine oil such as Mobil 5 w 30 will give around 5 kw and better fuel economy over a non synthetic oil.
  • Fuel system service, MRT offer this and often get good results, cleans the EGR “gunk” out of the intake and combustion area.
    Also injectors as well as inlet manf and exhaust as well as fuel pump, lines and sensors.
  • Synthetic gearbox, transfer case and diff oil, again like engine oil this adds up in benefits.
  • Timing belt, fuel filter are again areas that should be checked and renewed.

SUSPENSION
Check out the performance / suspension section for REAL gains and benefits.
If I owned this car, I would invest some of my budget in the MRT XB kit and then brakes and suspension as this is guaranteed BEST VALUE!

PRIORITY LIST

  1. Check service history.
  2. Check the O2 sensor
  3. Check brakes
  4. ECU upgrade and re tune to suit local fuel (as all EVO V11’s are tuned for 100 ron fuel).
  5. New brake pads and discs if needed
  6. Front and rear sway bars.
  7. Complete (quality) exhaust.
  8. Front and rear sway bar links
