Lets talk turbo....

Well, the 3 series now has the turbo engine in the form of the 335i (3.0l TT). Has anyone heard through the grapevine if the Z4 3.0si will be upgraded to this engine next year? This could be a cheaper and possibly more desirable option to the M roadster IMO. But because this engine easily can tread close to the M's toes i'm a bit worried they wont release it in the Z4. Possible they would add this engine to the Z4 only after the M roadster gets the new V8 m3 engine, which is atleast 2 years away, so that would be bad news... Anyone have any further information? This is all speculation on my part..

Gdamn the next few years for the Z4 can possibly have one amazing lineup - V8 M3 engine from the next M3 and the 335i turbo engine.

Why wouldn't they just add the 335i turbo engine to the roadster or coupe in like the next year? The engine is already out.

That twin turbo engine is gonna be a monster and can be modded easily I'm sure.

Is there already a z4 3.0si? I never heard of this car, is it a more powerful Z4?

Yea, well basicly: the original Z4 had the 2.5l and the 3.0l 235hp engine.

Then when BMW bumped its 3.0l engine power with the E90 series of 3 series cars, the new engine was still 3.0l but with a bit more power (265hp) and so was born the 3.0si nomenclature.

If a 3.0ltwin-turbo engine (n54) were to be put in the Z4, they'd probably have to name it 3.0siT lol, confusing!!

Well they've already dropped the 335i twin turbo engine into the 135i and word is there may be a 535i also, so why not the Z

They are going to do that, but still haven't officially dropped the engine into the 1-series yet. But I still think its a little different since there is no M-1 car for a 135i to step on. But a Z4 335 would really be right so close with the M-Roadster.

Actually someone on e90post stacked up his 335i coupe against an M Coupe which is decently lighter and the M-Coupe put 1 car length of distance and they were otherwise equal, so that engine in the Z4 chasis would be an even closer match up. So that worries me that BMW would play politics and not give us this awesome engine until something more powerful comes out of M division..

Ah, but chip both cars and see if the results change

That's the beauty of forced induction.

Well thats my point exactly, that BMW will be reluctant to put that engine into the z4, because chipped it should outrun an S54 M coupe, which would be a problem for BMW. Thats why I have a fear the N54 engine (turbod) will not see the Z4 until a V8 engine is put into the Z4 m roadster/coupe

REVIVE THIS THREAD!!!

A turbo'd engine in a Z4 would be absoultely awesome. Has anyone thought of retrofitting an n54 into a Z4?

True but there is a valid discussion here, even though it hasnt been discussed in almost 1.5 years. Since I cant afford an ///M, I am brainstorming ways to make my car perform like an ///M without the price tag. I am only 17, and the 335i engine seems like a goal that is worth saving for.

lol, dropping an engine from a 335i would be more expensive than just buying an M more than likely.

Probably but im hoping that I will be the first to do it if i can find one that has been totaled from the rear or something like that. I highly doubt that BMW will put the N54 in the current gen. of the Z. IMO, BMW will wait to put the n54 in the next gen. Z.

I like the cars to be all engine. Turbo's are fun but a car putting out over 100HP per Liter is engineering. Look at some of the 911 Careera's. Producing unbelievable power from a V-6.

Regular 911s are not putting out unblieveable power (flat 6 not v6), its the 911 turbo thats the 800 pound gorilla at around 450 ft lb of torque and 500 HP to boot. I understand about perferring a normally aspirated motor versus a turbo or supercharger, but 100Hp per liter on a 3.2 liter aint going to let your run with the BIG BOYS, its hurting big time on torque at around 262 ft lbs and high in the RPM range. look at the new nissan GTR 3.5 liter twin turbo 450 HP and 400 ft lb of torque at 1,800 rpms thats unbeliveable power from a 6 cylinder motor...

For the cost, and pioneering engineering that would be required, you're better off buying a supercharger kit that will bump you into M territory power if not higher.

I could have miss read but on the Porsche Website.

911 GT2 Produces 530HP
911 GT2 Produces 415HP

Both are 3.6L V6 and if not wrong are not turbo. At least GT2 is not.

The Turbo/GT2 are both turbo charged, the GT2 incorporates a larger turbo as well as other mods to produce more power. The GT3 is a pure NA race car.

You mean:

911 GT2 - 530HP
911 GT3 - 415HP

Both Porsche models are naturally asperated.

Also the above models are both of a Flat 6 design. Very different from a V6 or Straight 6.

I am not familiar with the flat six but either way it is some real peace of engineering. Extracting so much power out of a 3.6L. It would be awesome to have a M coupe CSL.

flat 6 is all they every used in a 911, and its turbo charging thats creating that type of power the non turbo puts out around 325 Hp, no slouch, but your garden variety corvette with leave it in its wake....
