Evolution 1-8 Turbo info
Got some of this info from a http://forums.evolutionm.net/images/...mitsu_logo.gif brochure. Some of this may have been posted here before but here goes:
Evolution 1 Turbo = TDO5H–16G-7 Nozzle Area (cm2) = 7 Exhaust turbine = Inconel (steel alloy) Compressor = Aluminium, 60mm wide Evolution 2 Turbo = TDO5H–16G-7 Nozzle Area (cm2) = 7 Turbine = Inconel (steel alloy) Compressor = Aluminium, 60mm wide Evolution 3 Turbo = TD05H–16G6-7 Nozzle Area (cm2) = 7 Turbine = Inconel (steel alloy) Compressor = Aluminium, 68mm wide Evolution 4 Turbo = TD05HR-16G6-9T Nozzle Area (cm2) = 9 Turbine = Inconel (steel alloy) Compressor = Aluminium, 68mm wide Evolution 5 Turbo = TD05HR-16G6-10.5T (GSR) TD05HRA-16G6-10.5T (RS) Nozzle Area (cm2) = 10.5 Turbine = Inconel (steel alloy), Titanium alloy (RS) Compressor = Aluminium, 68mm wide Evolution 6 Turbo = TD05HR-16G6-10.5T (GSR) TD05HRA-16G6-10.5T (RS/rs2) Nozzle Area (cm2) = 10.5 Turbine = GSR - Inconel (steel alloy), Titanium alloy (RS/RS2) Compressor = Aluminium, 68mm wide Evolution 6 : Tommi Makinen Edition Turbo = TD05RA-15GK2-10.5T (GSR) TD05HRA-16G6-10.5T (RS/rs2) Nozzle Area (cm2) = 10.5 Turbine = Titanium alloy for both RS/RS2/GSR! Compressor = Aluminium, 65mm (gsr) - 68mm(rs) wide Evolution 7 Turbo = TD05HR-16G6-9.8T (GSR) TD05HRA-16G6-9.8T (RS/RS2) Nozzle Area (cm2) = 9.8 Turbine = GSR - Inconel (steel alloy), RS/Rs2=Titanium alloy Compressor = Aluminium, 68mm wide Evolution 7 GTA Turbo = TD05-15GK2-9.0T Nozzle Area (cm2) = 9.0 Turbine = Inconel (steel alloy) Compressor = Aluminium, 65mm wide Evolution 8 Turbo = TD05HR-16G6-9.8T (GSR / USDM E8) TD05HRA-16G6-9.8T (RS/RS2) Nozzle Area (cm2) = 9.8 Turbine = USDM EVO 8 & JDM GSR =Inconel (steel alloy), RS/Rs2=Titanium alloy. Compressor = Aluminium, 68mm wide Evolution MR aka "8.5" GSR = TD05HR-16G6-10.5T or TD05HRA-16G6-10.5T (Ti Alloy option) RS = 6MT:TD05HRA-16G6-10.5T or 5MT:TD05HRA-16G6-9.8T Nozzle Area (cm2) = 10.5 or 9.8(RS-5speed) Compressor = Aluminium, 68mm wide All Evo 4-8 Turbos are twin scroll designs meaning that the engines exhaust is divided into two channels (see first pic). As the engine exhausts in pulses.. its supposed to result in quicker spooling. From the Evo 4 onwards, the Turbo spins in the opposite direction, i.e. Anticlockwise (hence the R in the turbo name). The Titanium Alumnide alloy used in the RS/RS2 and some GSRS (factory option) has less inertia and thus spins up around 500 rpm sooner. These Titanium turbos can be indentified by the A in their name. |
