    Matibay naman talaga engines ng Isuzu. Trooper 4JX1 lang ang panira

    Fuel economy, Isuzu. Pero yung Trooper ni s_quilicot nakaka 6-7 km/L lang daw. hehehe

    Power? Di na kailangan itanong. Hyundai iniwan ko yung Montero Sport GLS SE sa SCTEX.

    CVT, sa bagay mukhang mas matibay ang Hyundai. Wala pang Hyundai CRDi ang pumapalya diba?

    Hmmn I am now getting confused.

    Many of you guys make contrasts between CRDI engines vs ISUZU engines.

    But isn't ISUZU Alterra's engine a CRDI?

    Yup CRDI din ang isuzu 4jj1, problem is the turbo they use locally. non- variable geometry yung turbo. Kaya di competitive when it comes to performance. At talagang panira yung 4jx1 sa rep ng Isuzu.

    Yes, the 4JJ1 found on alterra and the d-max are CRDI engines.

    But Hyundai markets its diesel engines with the "CRDi" label, just like how toyota labels the D-4D, mitsu with the D-ID, and isuzu with i-Teq.

    no biggie, it's just semantics.

    regarding the topic... Isuzu's no longer the "authority on diesel engines".

    yes, they have tried and tested designs, but in terms of sophistication? Napag iwanan na talaga sila.

    None that I heard of bro. Even with the dirty diesel which we are currently 'enjoying' here.....

    For CRDI type engines, injector durability is everything.

    Modern engines can last well over 300,000 kilometers, if need be. But modern high-pressure injectors often fail long before that.

    While I put my faith in the durability and long-term use of Isuzu's old-school overhead valve 4JA1s and 4JB1s (have one close to 200,000 kms, and two others at around 170,000 kms plus), Isuzu's more modern engines use Denso technology for their common rail system. Even in Europe and Australia, Denso systems have a bad rep (guess who else uses Denso? D4D problems, anyone?), and the Bosch systems are considered king.

    Old Isuzus and Nissan Patrols with the Denso high pressure systems have numerous problems (and these are not just limited to the 4JX1. There are rumors about the Alterra now). Some Toyota Denso owners are on their third fuel pump. Hyundai? They use Bosch. One member here is still on the original injectors. Even after being "Ondoy'd". At 300,000 kilometers. Now that is impressive. I've only ever heard of one or two injector failures stories for Hyundais, and they were old Starexes with over 150k kms.

    Nowadays, it's no longer enough to cite the brand of the car... with boutique specialists like Bosch, Siemens and VM Motori (they make the Captiva diesel... pretty good diesel, that one) taking more and more responsibility for engine technology, you often have to ask what particular subcontractor/supplier built the engine and engine hardware.

    This thread needs an update. Nag improve na ang Isuzu engines, dba? The FC of their pick up is really impressive, going 30 km/ lit. Talo pa compact car diesels.

Better diesel engine, ISUZU or HYUNDAI?
