Getting the correct grade of tuning upgrades for your planned usage of the car is vital. Stage 3 motor sport mods just don't work well on the road hard to control in slow traffic.

Best mods for your 2 Series

  1. Brake Upgrades - Enhancing your stopping power ought to be near the top of your Mods list.
  2. Flowing and porting the engine head - for larger gains, you will get better flow and make a more efficient engine if you do this to support your other mods.
  3. Forced induction upgrades - forced induction is the most significant way to increase air supply, ensuring you are able to combust more fuel and make better power figures. It is one of the most challenging modifications it does provide the largest gains.
  4. Lighter flywheels - a reduced weight flywheel will improve the engines rev changes. In some cases flywheel lightening is not not a great upgrade for all 2 Series engines.
  5. Tunes - A tune/remap provides the most power compared to your outlay, aftermarket ECU upgrades, and piggyback ECUs are all alternatives.
  6. 2 Series Suspension - Replacing worn bushings and shocks dramatically improves 2 Series handling Adjustable coilovers and better bushings are what is needed here.
  7. Fast road cams are significant power adders, but we recommend they be fitted by someone who knows what they are doing and it can sometimes be hard to find one but you might find a local firm to regrind a stock camshaft for you.
  8. Intake Mods and Exhaust - NB: on their own these mods won't ADD HP for most setups, but they enable you to enhance power after other upgrades by lessening the restriction.

2 Series Tuning Stages

Typical stage 1 mods often include: Panel air filter, Alloy wheels, Engine Tunes/Remapping, Lighter flywheel, Suspension upgrade (drop 30mm - 37 mm.), Sports exhaust.

Typical stage 2 mods often include: Fast road cam, Ported and polished head, Power/Sport clutch, fuel pump upgrades, high flow fuel injector.

Typical stage 3 mods often include: Competition cam, Engine balancing, Adding or upgrading forced induction (turbo/supercharger), Sports gearbox, Internal engine upgrades (pistons/head/valves).

You really need to keep as much low end torque as you can and aim to get a wide power band across the rev range rather than a narrow top end power spike.

The aim of our advice is to give a brief overview of modifying modifications and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your modified car project, the best tuning upgrades and all aspects of modding cars.

2 Series Handling/Suspension upgrades

Improving the handling for DIY mechanics first priority in your 2 Series tuning project.

Setting a small amount of negative camber on the fronts and a few degrees of toe in to improve stability or toe out for better cornering, will substantially improve your 2 Series in handling and cornering.

We suggest that you fit sports suspension and lower the car by 30mm - 37 mm. Larger drops require arch work - especially on models already equipped with uprated suspension.

Adjustable Coilovers enable you to lower or raise the car and this allows you to fine tune your cars handling.

Is there anything I should keep in mind while deciding on suspension upgrades for my 2 Series?

Upgrading your Bushes

Enhancements to the bushings: Things you need to know

It is possible to connect the 2 Series's suspension components to the chassis of the 2 Series using poly bushes, which are drop in replacements for the original rubber mounts. The rubber ones usually start to fail with time and need replacing anyway so why not upgrade.

By replacing new OEM rubber bushings, you may greatly improve your vehicle's performance.

It's probable that the ride may be a touch rougher because of the stronger polyurethane bushes but they'll last longer and maintain tighter handling.

They may also quicken the stress of other suspension parts due to the increased vibration and play.

A new set of polyeyurothane bushings may be able to lessen the excessive play that comes with rubber bushes.

Top end power should be your overall aim with a nice fat wide peak torque band.

Enjoy your 2 Series to the limit with our hot performance tuning advice - do the right mods in the right order.

To be completely frank and honest, on the more modest engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Fast road cams offer one of the biggest power gains for your money as far as a solitary modified upgrades goes on a NA (naturally aspirated) engine.

It improves the intake and exhaust flow and increases the power if done right. Ideally you'd add other mods and finish up with a reflashed ECU. We'd also caution you not to go with a motor sports profile cam as this upsets the engines idling and general town driving characteristics.

Don't forget to pay attention to the fuelling when you are increasing the power - it makes the car more thirsty.

Using high octane petrol is another option if you find you are suffering from pinking or premature ignition on your BMW project after fitting other performance kits. To get sufficient fuel you may need to increase the injectors on your engine.

If you are increasing your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

2 Series Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT FIND IMPROVEMENTS WITH INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become limited.

Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for 2 Series engines you should settle for a high performance panel air filter preferably made from cotton.

Sports exhausts generally help improve air flow from the engine but do not go too big or you might just stuff your flow rate and make things worse. So generally speaking, keep to a size of 1.5 to 2.5 inches for best results.

Getting a professionally flowed (ported and polished) head with larger valves can fully release the engines power.

When you heavily modify your 2 Series you will discover that the standard clutch starts to suffer so get an uprated clutch. The best mods we recommend for your 2 Series are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Turbo engines are just pleading to be Upgraded. You will see impressive power gains on most modern turbo engined cars including diesels making a tune/remap one of the most cost effective and impressive modifications for your money.

Despite the large cost involved adding forced induction to a NA (naturally aspirated) engine will give large power gains. Superchargers are often easier to add than a turbo. It is difficult to map fuelling with a turbo as the boost comes on exponentially with rpm.

The nice correlating boost and rpm characteristics of the supercharger make them simpler to map. To cope with forced induction you will usually need to decrease the engines compression ratio .

The benefits of alloys include a lower unsprung weight and more efficient brake cooling. If you are serious about performance then you will need to carefully choose your tires - ideally with a soft compound tire. The downside to large rims on your 2 Series is that you're altering your final drive ratio so this will have a negative effect on acceleration and performance.

Due to this fact aim to keep the overall rolling diameter of the wheel your OEM settings. In all cases we do not recommend going bigger than 18 inches. (And ditch the Runflats!)
