Hiya. Galant 2.0L SEI SOHC Auto 1994, New Zealand new.
Our 2nd car for around town running.
Fuel:
Says to run on 91 RON Octane unleaded in manual. But that was in the days when our 96 had lead in it and only 91 was unleaded at the time. Would I benefit from 96 Octane Unleaded, or is it wasted? The fuel in New Zealand is crap anyways. I heard that the higher the octane the more snot your car has. ie stick a little racing fuel in her.
Catalytic Converter
In New Zealand we have no law to say we cannot rip out catalytic converters. Would the car benefit from ripping it out? I did it to my Legnum and it seemed ok. The muffler shop told me that only one vehicle they know of ran like crap without one and it was a Ford F350 (???) big US truck) or something.
It's no pimped out racing car for sure, but I'd like to get the most out of her.

i would try to run good fuel...pulling out the catalytic converter is only going to make it loud...maybe add a couple of horsepower personally i wouldn't do it but its up to you

The Legnum is dead quiet even with cat removed. They have a stupid big muffler at the rear instead of a resonator. The Galant is the same. I figure a cat is the equivalent to jamming a sock up ones exhaust.

no a cat has catalystic converters in there i.e it will burn up excess gass (and dirty exaust) so the final product is much cleaner. hey its all up to you sure youll get a lilttle power but at the cost of polluting more

Found out that NZ new cars don't have catalytic converters. So not an issue. Presumed it would cos my Legnum did (Jap import). :-)
Found out that even though the manual says 91 RON Unleaded only, Mitsubishi say 96 RON is better. I put 96 in it and some injector cleaner, and now it idles at 1000rpm. I will wait until nest tank of gas before getting the idle adjusted for 96.
BTW, how is idle adjustment done on these cars? Carbs are easy enough - never done anything on an EFI.
