It's not easy to compare two different types of engine to one another.
Against the prehistoric 4JA1? Not really a comparison... the 4JA1 lasts a long time... any damage from poor maintenance and fuel quality takes at least 150,000 kilometers to manifest.... the common-rail 2.5 D4D can show damage as early as 60,000 kms.
But against Isuzu high-pressure direct injection engines like the 4JX1, durability is similar. And that's what you should be comparing it to... as the old 4JA1 can't pass modern emissions requirements in developed markets, like the D4D can.
Hell, my 4JA1-powered Crosswinds barely pass our even more prehistoric local emissions requirements... which is why the ASBUs keep trying to flag them down.![]()
