- Advertisement -NMAA News – Tuner spesialis performa mobil asal Jepang, HKS menjual racikan mesin legendaris Mitsubishi berkode 4G63 untuk memenuhi keinginan para car enthusiast dan modifikator mencari mesin donor. Bagian jantung pacu short block ini biasanya menjadi part standar Mitsubishi Lancer Evo IX. Tetapi, sudah mendapat oprekan di bagian stroke dan bore mesin oleh para teknisi HKS dari awalnya 2,0 L (1997.4cc) menjadi 2,3 L (2204.7cc). Perlu diketahui, lantaran short block 4G63 HKS tidak termasuk dengan bagian head, saat memesan konsumen hanya mendapat block berbahan billet, forged piston, billet crankshaft, dan H Beam Connecting Rod. Soal harga, satu set mesin short block Mitsubishi 4G63 2.3L dijual seharga $12.000 atau setara RP 179 jutaan dalam kurs rupiah.
FYI none of the evo engines can be used on a 1g (90-94) DSM due to the lack previsions for front/rear motor mounts that all EVO's have. In short, other than that there isnt much difference between a 2g dsm besides the slightly higher compression ratio and the fact that they dont have crankwalk problems. As you said they have a bigger turbo, and also bigger injectors. The final drive ratio is different in the trannys, 1st gear also has a closer ratio to 2nd gear (ie your first gear will go to like 35-37mph)... But with the lower final drive ratio you also need the rear diff gears and you get a much lower top speed.
Reciprocating internal combustion engineThe Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn. A UK-market Evo known as the FQ400 had a 400 bhp (298 kW; 406 PS) version of the Sirius, making it the most powerful car ever sold by Mitsubishi. It is found in various models including the 1988-92 Mitsubishi Galant VR-4, the U.S. market 1990-1999 Mitsubishi Eclipse, and the Mitsubishi Lancer Evolution I-IX. A SOHC carbureted eight-valve version (engine code G63B) was also available in Mitsubishi's pickup trucks (L200, Strada, Mighty Max, Dodge Ram 50) from the eighties until the mid-nineties. Mitsubishi ceased any further development and production of Sirius engine after 2012 model year, and its Chinese joint-venture, Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., is now the only one producing 4G69 engines.
