Okay guys! This is a loaded question I know. I just got my Z4 a couple months back and have been doing all the basic stuff to be sure that it's mechanically sound. I want to do something to mod it now. Give me some advice! What would you guys consider to be the best bang for the buck as a mod to increase horsepower? I was contemplating the air intake. Any thoughts??
 
Unless you're going to bolt on a super charger just give up now and save your cash. Probably not what you want to hear but it's unfortunately true. :thumbsup:
 
If it's power buy a z4m or Alpina as will be cheaper, but I would just make sure the suspension and bushes can be as good as possible to use the power you have.

Thanks for the honesty. I wasn't trying to make it a crazy fast machine. I just thought maybe an exhaust mod or air intake mod might get me an extra 15 hp or so.

Thanks for the advice
 
From the guys on here who know much more than me , the consensus is that 10-15 max is available on the M54 engine. Personally I find my 3.0 has more power than I have bottle.

I have a 2006 3.0si and it's already fairly spunky. I guess I'll just do some suspension work on it.
 
In that case it's an N5x , so have a word with Marlon, as I think he's had his tweeked and he's quite happy with it. Beware though he does like red :poke:
 
I have a remap , secondary cat delete , and a DLV back box mod ,trust me you can feel the difference . But what made the car feel notably faster is a sprint booster . The car feels like it has much more torque .
 
I had my last 3.0i remapped just made the throttle response a little crisper but obviously nothing like the gains of turbo or sc or a mapped turbo car but it worked for me👍
 
Secondary cat delete, remap and that's about it without spending thousands. But don't go expecting the same gains you'd get on a turbo engine!

Does anyone have the specific Sprint Booster part number they have had success with on a 2006 M Roadster?

It's called the sport button, does the same job! :wink: And it's free! Seriously I wouldn't waste you're money but, each to their own! It just sharpens the throttle, no quicker in reality.
 
The sprint booster adds to the sport button . That's when it has the most effect . No more power , just quicker access to it . You can use it without the sport button ,changing the throttle response gradually to highly responsive . On top of the sport button on its highest rating , it pulls you into your seat . If you floor the accelerator in sport mode without it on it feels nice as we all know . With the sprint booster on it has extra force in gearing up feeling far more responsive .
 
So all it does is change the pedal position for a given throttle position - not sure I see the point in that, less control and still the same power...
 
It remaps the throttle response so it's instant when set to its highest setting . So a more aggressive adjustable sport button that works on top of your existing one , if you have a sport button . I have an auto so the faster throttle changes the gearing , due to the revs red lining more quickly resulting in a gear change . Some super cars have sport mode then race mode . The Sprint Booster Is a form of race mode . You end up with a more adjustable quicker feeling car . You cant get your power down as quick by just flooring it without out one . Look at the reviews on YouTube . I was sceptical , now I'm not .
