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.




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

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.

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!

Any BMW can go 200k miles. It's just a matter of having the will and the $$. It's a question of durability. For example early electronic water pumps on the N54 would routinely fail just north of 50k miles. That's unacceptable to a Lexus owner who has 150k miles on his/her original water pump.

Well if you had the N20-N26 or N47 diesel you might have a different opinion about BMW and timing chains.

Yup.

I drove mine on a 2600 mile road trip and hammered the crap out of it. I drove through the smoky mountains, the blue ridge parkway, down mountain dirt roads, did tail of the dragon, and it didn't miss a beat. All while carrying plenty of gear for two people.

So would owners of the 3.5 V6 in many newer Fords.

KA- Ching!! and difficult to bodge behind the shop. The main reason I don't have a late model Ranger 4x4 is a rear cam drive 4.0L Take a good reliable little gas hog capable of 300K with little service and turn it into a grenade at 150K miles . A century of development going into push rod V engines. Then these OHC horror shows. What is the impetus to do this for Ford or BMW or any car maker?

Wait, so you didn't own a Ranger with the 4.0 SOHC V6 because basically two years of production might have had an issue with the timing chain which was solved after 2001?

My friend owned a 2001 which was one of the "problem" years and it went to 200k with zero issues before he sold it.

Toyota 2GR-FE had tensioner issues in first years too.

Sounds like the 5.7 HEMI water pumps. I'd still take replacing water pumps every 50k over a Lexus though.
 
As I've said many times before, if your idea of the pinnacle of automotive excellence is an anodyne travel pod that can go 300k miles with minimal maintenance, than a BMW is not for you. As for me, the enjoyment I've derived from the BMWs I've owned since 1983 vastly outweigh the additional expense of maintaining them.

These clowns just reduced the car to about 30k with problems once they put that back in.

Ah yes... long term reliability is at the top of my list in a custom built 1,000hp vehicle.

Or, maybe it takes 1,000hp with no major problems. You have no idea.
