Turbo X5
 

Has anyone done any research on a turbo for a 3.0 X5? Here's a source I found with many different options...

will it be faster than a 4.4?

I'm sure it would be depending on what stage turbo you go with. At some point though an upgrade of internal engine parts would be required. Anyone here have a turbo X5??? If not, I may be the first!!! I'll research it.

You will need to upgrade a lot of engine parts as well, I think. It would be interesting to see how many more ponnies the turbo gets you :dunno:

wouldnt it be wiser to just buy a 4.4 and sell the 3.0?

4.4 is much faster than the 3.0.

How much is a turbo going to cost w/ installation?

But other things come into play such as 4.4 gets worse gas mileage unless you get the 04+.

But yeah my friend's 330ci was turbo'd and it was a beast. Imagine turboing the 3.0 on the x5.

Can you only turbo a 3.0...or can you turbo a 4.4 or even a 4.8?

And are turbo kits on the link reliable?....lots more research to do i geuss

I owned a 600hp 300zx years ago. Turbos are a very tough custom install if you want it done correctly. Lots of custom plumbing, waste gates, intercoolers, Blow-off Valves, bigger injectors,Boost controller etc.. Even when installed getting the right A/F and making the engine strong enough to hold the boost will cost mula $$$. You'd be better off getting a supercharger, they are more reliable and easier to set-up and upgrade. Just my 2 cents

thank you silver 5....you dont understand what i was on the phone about to do...charger it is....
B.T.W does anyone know if the ESS charger kit comes intercooled/ can you intercool it?

Ok I`m probably going to look really thick here but doesnt the X5 3 already have a turbo? Are you talking about an upgrade turbo here?

Just answered my own question, yes it does already have one.. here:http://www.realoem.com/bmw/showparts...40&hg=11&fg=50

Your 3.0D should already have a turbo, but Lambeau was talking about the 3.0i (petrol engine), which does NOT have a turbo.

what is this D?

Diesel. I was at Ramstein AFB this past January & I rented a Nissan "Trail" that was a diesel and this thing was actually somewhat quiet and had gobs of power! It sure didn't sound like one of these P.O.S. big diesel fords and dodges that pull up next to you at a stoplight and irritate the shit out of you!

Right, thanks for the info. I love the gentle whistle when you pull away (from the turbo), but you can only hear it if you have a window down.

The diesel engines are higher stroke, so with reasonable boost pressure from reasonable size turbos, torque gains are substantial. The petrol engines on the other hand have much lower stroke; so one would need to flow much more air, in the form of a large turbo since it's a reasonably larger displacement. Not only is the stock, high compression not suitabe for boost, a larger turbo would mean more lag.

Why not just find a wrecked M3 with the front-end in tact, and drop that engine in the X5? You would end up with more HP than a 4.4 (but not as much torque), but a much lighter vehicle... Personally, I would just get a 4.4 or a 4.8... That way, you still have a warranty?!?!

M3 engine doesn't have enough torque to pull the weight of the X5. It's power is also more concentrated higher in the rev band relative to the engines offered in the X.

It would def be more practical to get an X5 with a v8.

I wanted to get the 4.8 but I WILL NOT drive an automatic! Automatics SUCK! Why couldn't they have put the M3 man trans in the X with the 4.8? I'm sure it could handle the HP/torque.

M3 engine can't pull the X5 but the 3.0i can... ?

But I agree about the high revs - had an '04 M3 and was terrified to drive it a day outside of its warranty.. whereas the torque in the 4.4i is much more noticeable down low.. end result being an engine that doesn't really get pushed all that hard (much better in the long run I expect).

it's about the power + tq band.

That whistle is from the Blow Off Valve... Love that sound.

Stock engines don't typically have blow-off valves, they have wastegates. The whistle is the turbo.

There's an active member who has an ESS supercharger on his 4.6is. Pull up some of his old posts - he has some detailed information.

NOthing beats the sound of twin turbos spooling!! I miss my twin turbo set-up.:)

Did Sharka uninstall his turbo before he sold it? The main reason I want to go to the CT meet is to see your car. :)

heh...sounds cool,
actually he didnt get around to installing it, although he was about to, the intercooler was mounted in front, but im considering the ess charger this summer.

i actually seen someone take a ess charged 4.4 engine and place it in a m3, because they said it would leave more room to produce more power than the m5 would have.
