Auto Torques – Mitsubishi Evo IX Project
Full write up of Dean’s Evo IX engine build and pictures coming very soon. Watch this space.
Dean bought his Evo IX 2 years ago completely stock and straight away he wanted to start modifying it for use on the quarter mile.
The first changes were a 255 fuel pump , De-cat pipe , HKS air filter and ECU remap to give the car a healthy 380-390 BHP. Soon after these upgrades, we focused on the looks of the car, a set of custom mud flaps at the front , front carbon splitter and vortex generator followed by wind deflectors and lowering springs.
Following the power increase, better brakes were required, so Dean opted for Performance Friction grooved 2 piece discs, PF pads and braided lines all round. Then it was time for wheels, so 18″ Rota Grid Drift were next to go on.
The car was now performing well but after using the car for 1/4 mile runs an HD Exedy twin plate was installed for that extra clamping force on launches . Next on the list was a forged engine, to be able to support more power, so this is where we specified and built the engine. The main components of choice were; Kelford 272 cams , ACL race bearings , ARP head bolts, Forged pistons and Auto Torque 800BHP Con-rods, Full ECU remap to bring the standard 80 series to 417 bhp .
But it didn’t stop here. Dean felt the need,(like most do) for a bit more, so went for an uprated AMS Intercooler, Gizzmo boost controller, Upgraded boost hoses, GTX3582R turbo and large K&N filter running speed density , HKS SSQV BOV, AMS fuel rail and 1000 cc RC injectors with a Sard fuel pressure regulator all with braided lines , hard wired the 255 in-tank pump and fitted a Bosch 44 pump with swirl pot and a C-O-P kit fitted with BPR8 spark plugs . Next on the list after this power increase, was to fail safe the transmission, time for a strengthened 5 speed box. We stripped all the gears out and super finished every internal part to increase part life, decreasing wear, run closer tolerances on all components. On order now is a Sparktech coil set up and a full 3 inch Nur Spec exhaust.
The car is now much more suited and capable for Dean’s 1/4 mile runs at Santa Pod
