Bmw Mods

[SpazHairlip]

Hello, I’m new to the boards, and know very little about BMW’s (I’m a 05 Mustang GT and C6 Corvette owner) but I also have a 94 318i. The reason I’m here asking questions is because my friend is going to buy a 5 series (I’m not sure which one, but it will be 4 door) and he asked me what mods he can do to the car (since he always watches me adding something to the Mustang).

If there are some BMW performance sites that you guys like, or just some products that you have tried, or tips about what sort of modifications can be made (intakes, cat-backs, chips or tunes, etc) that would be great. Also, with my cars, I need to use computer-tuning devices to ‘tune’ the engine (change timing, fuel curves, torque management, etc) that add performance gains. Are there similar products on the market that work for BMW?

Anyway, thanks for the advice and tips.

There is a fairly large aftermarket for BMW, The 5 series market is a bit more limited than the 3 series market, however you've still got turnermotorsport, Supersprint, Dinan, BMP Design, Remus, Dinan, Active Autowerke, and Bavarian Autosport who can provide the preformance gains you're looking at.

But dont only look for horsepower, many of the best upgrades for BMWs occour in suspension work

It all starts with a simple chip upgrade. $250 or so - adds 10 hp, 10lb-ft tq on average. sometimes less, rarely more.

in a 525, they'll be looking at 189hp - DEFINATE room for improvement. Although thats excellent power from a 2.5 liter, it feels slow in a large car.

In a 528, they'll be looking at the same hp, but more torque. still feels slow IMO.

theres the 530 with around 220hp from a 3.0l I6
theres the 540 with around 292hp from a 4.4l v8 with roughly 325lb-ft tq.

Let him keep that in mind when he looks for them. More mods are available for the I6 cars than the v8 ones.

However, almost all of them have headers, CAI, cams, software, etc (basic bolt-ons).
