Car Forum / Mitsubishi Cars / February 2007n/a JDM 4G63 vs US 4G63
Looking at a couple of JDM engine inporter sites, the normally aspirated JDM 4G63 (ECI-Multi) is rated at 170hp, while the US/Canadian 4G63 is rated at a mere 135hp. I could understand another 5-10 hp due to higher octane fuel and different emisisons standards, but to get 35hp would require most or all of bigger valves, more cam overlap and/or lift, higher compression, bigger injectors. The importers didn't have a clue. Anyone know what the specific differences are that give the additional 35hp?

Might be worth considering, though I'd have to use premium grade gas. My 93 Summit Wagon's 4G64 SOHC-16v is v-e-r-y- tired and burning a lot of oil. Its rated at 145hp, at 9.5 compression, and run regular gas quite happily. Could be worth swapping it out for a 160-170hp 4G63 DOHC. A few years ago I swapped the 4G63 SOHC 8v in my old Vista 4WD wagon with a 4G64 SOHC8v. The extra torque from the long stroke was nice, but it didn't rev usefully much past 5000. The 4G64 SOHC16v in my Summit wagon revs way better with lots of torque. Stewart DIBBS www.pixcl.com/lancerproject.htm |
