BMW went to a modular manufacturing process for their engine blocks in order to reduce costs. Part of this process included the standardization of the location of the timing gear to the rear. B-series engines include Inline 6,4, and I think 3 cylinders. In addition these blocks are all closed deck which enables them to be used for diesel-powered variants. BMW has a history of timing chain issues and IIRC the guinea pig for this layout was the 4-cylinder diesel N47. Some N26-N20 also have timing chain issues (extended 7/70 warranty for affected models).

In the past BMW had unique blocks for the various engine types (gas/diesel, I4,I6).

Looks like a solid performance engine but I don't like the rear cam chain and I don't like tearing apart a brand new engine. Still enjoyed the video laugh

He has a bunch of really good videos on his channel. I remember back when people were first starting to race Hondas he was the front runner in the import drag racing scene.

Interesting to say the least.

So what happens to the Supra now? These guys will slap the engine back together, reinstall and get it on the market at a discount? Sounds like a upcoming thread here on BITOG.

That's probably what they said of Audi's S4.

That is reason why I do not like it. But, it seems that this is far less problematic (if at all). Also, on some BMW forums I read that engine actually does not have to come out using tools specific for this generation of engines. How? Have no idea.
Also, BMW brought back regular water pump. But they just could not help themselves and had to put ECU run thermostat.
Also, looking at video I noticed oil filter housing to be completely new design. Gasket on those was an issue forever on BMW's. Cheap to do it, but annoying.

I think it will be going into one of their racecars.

They're claiming 335 hp.

335, but as it is always the case with BMW, numbers on wheels are much higher than they should be considering hp on crank. BMW has really efficient hp transfer to the wheels (that is argued). So either they undervalue hp on crank or drivetrain is really efficient.

335 HP stock and they want to get 1000 HP out of it. eek The main bearing design (with the windage tray adding support) looks kind of wimpy to support that level of power and remain reliable. Should be interesting to see how they do it.

It all depends on what the parameters of 'reliable' are. There have been turbocharged Hayabusa engines developing 1200 hp.

People get 900hp out of BMW N54 regularly and for the power, they work pretty well.

The version used in the M340i makes over 380 HP. This SUPRA version was purposely de-tuned (My N55 makes 335 hp). What I wonder is whether or not the coating on the cylinder walls can take the added load. This engine is NOT sleeved.

So much ignorance and fear of anything new. My n54 has 210,000 miles on it, original chains and turbos, and I'd be totally fine if the chains were on the back. I've had BMWs for 20 years, and had only one chain tensioner go weak on my 318is from 1991. The rest have been perfect for 250k+. I just drove to Detroit and back and loved the performance and relative efficiency, even running 5-40 Delo.

This engine looks like a simplified version of my n54 in some respects. The lack of driver engagement of modern BMWs is worthy of a lot of criticism, but not the engines.

Anything other than penalty boxes... I mean econoboxes... I mean boring appliances... er, frugal, reliable vehicles are automatically disregarded for being too expensive or referred to as “unreliable” with absolutely no real world experience. It is IMPOSSIBLE to drive a BMW 200k with no issues! wink
