N54 Swap anybody?

[Erick]

Hell yes.

[chuckybob]

i love the part about no turbo lag, but its so ugly... i dont ever want to own a car where you always have to remove two things to get to something else

[Insanity]

I wouldn't say they've really maxed out the I6 at that displacement level, just that they aren't willing to build some super crazy revving engine due to their target market. Just one more problem with BMW trending towards a luxury brand.... blah.

[Jarvis]

Its no N50B32

No, N54B30. It's the same motor as the N52B30OL, except an all aluminum block instead of magnesium-aluminum, and obviously the addition of the turbos.

For about 1 year before the official release of the Z4 M-roaster and the news that it would have the S54, BMW said it would have an "N54"... weird.

[Mystikal]

Now the question is what is the M3 going to have? If the regular 3 series has about as much as the old M3 had power wise then they definally are going to step it up. They need to drop a V8 or something unique in 3 series line like the E30 M3 had with the 4cyl.

BMW confirmed years ago what the E92 M3 will be packing. Think M5 V10 with 2 holes chopped off. 4.0 V8, 8250+ redline.

Yes they have maxed it out. The S54 is a prime example of it.

[Mystikal]

For sure. Did you guys know the CSL S54 has the highest lb-ft per L of any other production NA motor?

You have no clue what you are talking about.

[Bavarian3]

They will be here in the US. Either 328 or 335 in the coming production models.... this is confirmed.

M-Roadster is out next month... and Coupe is coming in June.

M6 is going to be in a convert coming soon as well!

[Insanity]

Right, they've maxed it out, hence why there are absolutely no aftermarket parts for the engine, and they definitely race the engine in stock trim. You're off your rocker.

M coupe is supposed to be a 370hp s54... I dont see how you can get much more power out of a 3.2 liter (assuming they're keeping that displacement. I dont think that there much room to go much higher than 3.2 and still have a reliable engine. Maybe its 3.4 or so, but that is still some killer hp/L.

They should be able to make a reliable 325 - 350hp out of that setup from the factory. Kinda lame to cap it off at 300.

[Ryan Stewart]

suprizingly it looks really straight forward. its very simple which is perfect for the application. too bad we still dont know if its coming to the US

Likely, as the mule was first photographed in the US almost a year ago. I dont know where the pics are anymore but it was an E90 (heavily mocked) with a rigged up boost monitoring and control kit taking over half of the passenger seat and telemetry shit spread all around the back. They found it at a truck stop in a caravan and MFG plates.

Sounds badass!

Nah, the M roadster and coupe will have the 'plain-old' S54, 333hp. M roadster will be here next month, coupe in May or June.

This is the new Supra engine / Skyline engine,
This engine is the lates and greates in technology,


BMW has been working on this project since 1991( this particular engine probably since 2000 )

The head engine designer was given a challenge wich
was a engine with max efficiency at all loads and rpms

Single Vanos designed by Rolls Royce and BMW made it into the McLaren F1 motor then the Euro S50B30 286hp motor,
and then standard production engines,

Double vanos follows

Variable intake lenght in the 2,8 Z Coupes

Valvetronic in the small 4´s

I´m surten this is a variable boost engine running valvetronic and or double vanos. Thus optimum cyl filling at all loads and rpms,

BMW was going to run pheunamic valves but that meant 48volt electrics,
and that has not happened yet.

The engine components in this engine are destined for 200.000km´s minimum
and beyond.

I´d say the BMW Turbo domination has begun
