4B12 Lancer GTS 2009

THE COMPLETE PARTS LIST FOR PIECING TOGETHER A TURBO KIT
All in all should cost in between $2000 and $2500, depending on how good you are at locating deals. This is by no means a definite list, just the easiest way to do it. The first list is only REQUIRED parts to get boosted, second list is RECOMMENDED to stay safely boosted and the third list is parts just for fun that complement the turbo build.

Required:

--OEM RA or Evo X Turbo/exhaust manifold/02 housing/downpipe/inlet elbow/wastegate (remember they either all have to be RA or all Evo. Can't mix and match)

--Recirculating BOV, aftermarket or OEM (has to be recirculating, can't release to atmosphere)

--BOV return hose

--Intercooler, cheapest is OEM but can go aftermarket

--Intercooler piping, UICP can be OEM, LICP will have to be custom or modified to fit if you have the stock intake manifold.

--Intake, OEM intake tube with an after market air filter is cheapest, but any Evo X or RA intake will work. If you go OEM, remember MAF housing

--OEM 3 Bar MAP sensor (replaces stock 1 bar sensor on the intake manifold). Aftermarket is a pain to work with for tuning, but it will work.

--OEM Evo X or RA injectors

--Wideband (Innovate LC-1 is a good and cheap option, AEM makes another good one)

--Spark plugs, have to be one step colder than stock. NGK and Denso make good ones, heat range 7 recommended--Boost gauge and A/F gauge, any aftermarket will work

--TD04 or TD05 oil/water fittings kit (depending on which turbo you have)

--8an weld on bung (Ralliart turbo) or 10 an weld on bung (Evo turbo), this is for the oil return line to the oil pan

--Either Evo X ROM or AEM F/IC 8 with custom NA ROM (need the F/IC if you don't use the Evo ROM because the stock ROM doesn't scale beyond 100% load)

--All necessary gaskets, bolts, nuts, the little things that are too many to list but should be obvious as you install


Recommended:

--Transmission cooler (especially for CVT) Mishimoto has a great one, but any aftermarket is fine. Most will required custom brackets, but that's super easy to do.

--Engine oil cooler. Again Mishimoto get my vote, but any works.

--Evo X or RA Fuel Pump.

--Evo X IAT2 sensor. This is a second temperature sensor that the base Lancers don't have. Makes tuning a bit easier. Otherwise your ECU will read a constant 25 degrees Celsius, which obviously isn't the case.

--Manual boost controller. Cheapest and easiest method of controlling boost and wastegate flutter (can use to increase boost). You can also use an electronic boost controller or install the Evo X or RA wastegate solenoid.

--(For CVT only) Kinugawa .3 bar wastegate actuator. This will start you off around 4.4 pounds of boost if you're nervous about boost pressure, can increase with a MBC after you're comfortable

--Evo X GSR ECU. This eliminates the exhaust camshaft sensor DTC (P0365) that you will have if you kept your stock ECU. The VIN will need to be reprogrammed by your local Mitsubishi dealer. This is required for any Lancer who's year is 2011+, as Mitsubishi added ECU security to prevent non factory ROM flashing


Really not required, but makes life easier and/or makes you go faster:

--Thicker head gasket. This is the easiest way of lowering your static compression ratio, allowing you to run more boost.

--Forged pistons. I went over in a previous post what will work, so I won't beat a dead horse. Can run more boost with these, lowers SCR

--Evo X camshafts. You'll make more power, and tuning will be easier.

--Instead of using OEM gaskets, use metal-graphite gaskets. This is a great way to expel heat, making more power

--Bigger brakes. How the hell else are you going to stop after you get all that power?

--Transmission temperature sensor and gauge.
