hp should b same....sumore carbie can drag more...no speed cut o rev limit rite...
i've seen 4g91 wit single weber also damn powerful...

carburetor have higher FC
you must control very good to keep the FC low and HP are lower then the injection one! and also engine are more than 15 years since injection 4G91 EFI introduce on year 1990 (forgot liao)


but but but carb engine less headache every experience mechanic can tune it
but injection must used some computer to tune it!

y proton injection feel less power because of simen ECU not mitsubishi ECU

wow thats almost 20hp diff.go for injection lo then :)

 

[amad108..]

the big diff is on thier cams... if carb engine use injection cams sure got more power for carbie... i already see the diff between injection n carbie cams... n somemore the 4G91 carbie is hard to get fine tune coz the carb really complicated which got too many wire n air tube like electronic carb....

n bobo where got carb with ecu ma... hehe, but if i'm not mistaken merc190E is combination of carbie n injection where the engine got injector but only one....

if i'm not mistaken 4g91 carb also got ecu control... correct me if i'm wrong ler..

it is not really an ECU la.. but it is electronic control it's called Electro-Carburetor if I'm not mistaken.
