This is my 1st BMW. First German car in fact but I'm loving it. I picked up a 2008 X5 4.8i Sport that is monaco blue. I'm a big time modifier so I'm getting the bug already. I upgraded the HID bulbs and angel eyes bulbs and looking at an are kit next and having the black plastic body panels painted as well as a more aggressive hood.
The only issue I have would be the lack of aftermarket following the X5 has and on the forums every time someone talks about any kind of power adder people only tell them to trade it in on either a i50 or an M. I mean I had a WRX that I modded to out perform stock and most modified STi. I get starting with a better base is always the best way to go but come on. I can't imagine a 360hp motor being a bad place to start.
In any case I have a few questions I was hoping to get answered.
- How much Wheel HP will the trans hold before letting go?
- How much HP will the motor hold before it goes boom?
- Can the ECU be custom tuned or are there only built maps for it?
- Has anyone else done any custom turbo setups on the 4.8i?
I normally do "Dash before Flash" but with this car I think I'm going to tackle the looks of it first and then focus on the motor but I know at some point I'm going to want a power adder and after researching what is out there and the price it's most likely going to be a custom turbo setup. Nothing too big but something that can run with the X5M would be nice. But then again this is all on the idea that the ECU can be custom tuned.
