Просмотров 1634 часа назад
Based on my own blog: drjlt.com/article/tech/401/bmw-n74-vs-n74tu BMW’s N74 is the most technologically advanced V12 engine in a road car.

    Only two truths you said is w126 beating e23. And g70 beating w223. There is no doubt the w126 is a collectors sedan next to 60s 'holy grail' 600benz. However everything else you say is not accurate. The big 7 series beats all sclass generations. Some generations it's close. Some it's no debate. Biggest difference is w221 v f01. The f02 is much superior than the competitor w221. All these cars should be lwb

    I feel like the toyota and the vw engine should be both one tier higher and the mazda engines both one tier lower. In reviews it was often said that the mazda engines are good for cruising but not sporty at all and can feel stressed easily under pressure. As you also took into account in what cars these engines are used.. fhe mazda engines are all in boring suv's. The vw engine is in sportscoupes, cabriolets, porsche shooting brakes and other exciting cars.

    Even if the Nissan engine is a better tuner platform (not sure about the Alfa one cuz it's just not as widely used as the Nissan one for such a task), the Alfa Romeo engine sounds so much better that it's not even funny... VR38 doesn't have anything on the 690T when it comes to sound!!

    Interesting video, but many of the points are subjective / qualitative rather than objective / quantitative. To be transparent, I own a BMW with an S55 engine, so I have a bias. Is a 2JZ built from all aftermarket parts still a 2JZ? If you're changing many or all of the parts to aftermarket, it's not fair to compare it with a stock S58. The S58 block is aluminum, which is much lighter than cast iron, but you didn't give it credit for that. It's relatively easy to get 1000HP from an S58 with excellent reliability and drivability.

    Great video JLT 👍👍 how much do these go for in China? You can tell me in RmB and I can convert, I was just curious because for years in the US these have been very low/reasonably priced with many in the $4000-$10000 range. AMG cars are around $8000-$20000, which is considerably lower than original msrp. Would be cool for you to make sone videos talking about cars people like in China and differences like how coupes are more expensive used (same here but not to the same degree)

I have 2 questions. 1. where can i find that aluminium repair kit. google didn't help me 2. did your keyless go work with the incorrect door lock? auto unlock when you plache your hand on the door handle, and lock when you push the lock button on the door hendel (key in pocket )? I have a part car with Soft-Close and my daily have only keyless go (the programing is no problem)

      I found it in China. There must be someone selling these on eBay or Aliexpress, but I haven't looked. Interesting that you asked about KG: my KG was not working but started working after this fix. Apparently, there's a tiny short on the connector to the driver's door handle. Yes, KG works just fine. Just have to wait a second for the vacuum unlock.
