Does anyone know if the Turbo can be retrofitted into the current E90 330i without compromising the intergrity of both the engine and the vehicle as a whole

You can not be serious with this? Since it is your first post I will guess you have not discovered that reading threads is a good idea and using search works well too..... but
The turbo engine has not been released in a production model yet, it will not meet US emissions in current form, The entire engine is different than the current N52 in the E90 330i it is not that they strapped on some turbos and said yeeee hawwww. Could you buy the motor in a few years and put it in ...... sure. I suggest you do a little reading there is a lot of info here and you could have answered your own question. Sorry to be a PITA but you can answer a question and that is it or tell someone how to answer their own question and improve there ability to acquire the knowledge they desire, I always will choose the later. Best of luck

BMW didn't take a 3.0 inline-6 and just slap 2 turbos on it. It's a COMPLETLY different engine that been in development for 3 years. The heads are new, the intake, the fuel delivery..etc. Even the BLOCK !!

You are quite correct. When a company like BMW does something as serious as turbo-charging, they don't take it lightly. Reliability and efficiency are their main issues. Anyone can bolt on a custom manifold and turbo on an engine, but there is so much more to it when you are 'engineering' an entirely new motor from the ground up. I personally have never been an advocate of aftermarket turbos. My saying has always been, "If it didn't come from the factory with a turbo, don't put one on."

I think that would not be practical, since the turbo engine is a complete new system with different engine management, intercooling, and piping. Everything would have to be changed, so why not buy it from the factory with a warranty?

[stressdoc]

Not practical. Sell your 330 and buy a new 335 if you must.

"So, now we have the whole pic: 306HP N54 in 335i, 330HP N54 in 335si (with optional ZSG gearbox).

335si still not US confirmed.

Also not know yet: the N54 US version specs - could be slightly different to Euro specs. "

where is the post or press release stating there will be a 335si? I see all the 335i info, but nothing at all about the 335si. Is this just guesswork and speculation, or was something published on another reputable site about the 335si?

Only official word is on a 306Hp turbo engine, nothing about what the car will be callled ( but we know it will be 335i )

335si info is only from a board member ( GregA I think )

Seeing as its a completely new engine with different block, pistons, exhaust, fuel system, ECU, inteke ect ect ect id have to say NO

Here's some inside info:

Coupe's will be 335ci and 328ci. (Early summer) The 335ci will be the twin turbo motor with about 300hp. The 328ci will be NA with about 235hp.

In the fall (Septemberish) the sedans will get the new engines with the same designation of 335i and 328i. Base price of the 335i will go up about $1500 from the current 330i.

Would be awesome... how do you know?

Is this your guess / prediction for North America?

My local BMW dealer told me this info back in November...so no real inside info here...

I read with great amusement the Google translation of the
German press release. Perhaps if it were translated back into German and then back to English by Google, we might get something resembling Shakespeare.
Thanks for a great post though.

This following post sounds more like what's going to happen:

Oh no, lag! Yeah, that's a big problem in an Evo 8 with a 2 liter four pot (which is probably worth no more than 110-120 hp on its own, even at regular compression ratios) and a huge snail that doesn't reach peak boost until 3500 rpm. But this isn't a 2 liter four banger with a slow spooling turbine.

Let me make this VERY clear: EVERY SMALL DISPLACEMENT GASOLINE ENGINE - NATURALLY ASPIRATED OR OTHERWISE - IS GUTLESS BELOW 2000 RPM. The N52 engines in the E90 RIGHT NOW are not diesels or five liter V8s! If you press the throttle at 1000 or 1500 rpm, you're not going anywhere for at least a moment or two - even in first gear. My own M52TU powered car protests any hard throttle inputs below 2000-2500 rpm, and the power doesn't really begin to ramp up until the engine is past 2500 rpm. If you're worried about having no power below 2000-2500 rpm in a fairly small engine (because the turbos haven't spooled), you're a damned fool.

Now, if you're worried about throttle response (though I don't see how you can be talking about throttle response when you're driving a lousy, limp pedaled DBW equipped car in the first place) ABOVE 2000 rpm, then I don't see what the worry is. These turbines will be spooled and making nearly full boost as early as 1500 rpm and will maintain it well through the engine's rev range. I have enough personal experience with small, low inertia turbines to know that you won't even notice that they're there (outside of a faint whistling sound) if you keep the engine in the meat of the powerband. I mean, hell, 1500-5800 rpm - you'd have to be an idiot or the laziest man alive to let the engine fall below that.

If you're going below 1500 or 2000 rpm (except when cruising) on a regular basis and actually expect the engine to do something for you down there, you either need to learn how to drive or buy an American car with an enormous, over-sized pushrod V8. Period.

Look, I have a lot of seat time in 1.8T powered Audis and VWs, as well as various modern turbo Saabs...chipped, unchipped, modified, stock...and I'll be damned if I noticed a bit of lag in any of these cars (and my daily driver is a naturally aspirated I6, NON-DBW, solid mass lightweight flywheel equipped BMW!), so long as I kept the engine in or near the meat of the powerband and wasn't trying to do 5th gear pulls at 25 mph. These engines use single turbines which are even larger than those of the BMW N54. Looking at the technical specs of the N54 and applying a bit of engineering knowledge and personal experience to the equation, I really cannot foresee a situation where power lag will be any sort of issue with this engine.

This guy knows what he's talking about!
