Hey guys! So, you're thinking about giving your BMW E90 a fresh new look by doing a front end conversion to the E92 style? Awesome! This guide is for you. This kind of conversion is a fantastic way to update the aesthetics of your E90, giving it a more modern and aggressive appearance. It's a project that many BMW enthusiasts undertake, and while it requires some effort, the results are often stunning. We will dive deep into every aspect of this popular modification, providing you with all the essential information needed to make your E90 transformation a success. Let's get started!

Understanding the BMW E90 and E92

Before we jump into the E90 to E92 front conversion itself, it's crucial to understand the differences between the E90 and E92 models. The E90 refers to the four-door sedan version of the 3 Series, produced from 2005 to 2013, while the E92 is the two-door coupe model that ran alongside it. While both share the same platform and many mechanical components, their front ends are distinct. The E92 boasts a sleeker, more angular design, with different headlights, a front bumper, and fenders. These differences are what make the conversion possible and visually impactful. The E90 has a more rounded front end, and the E92 gives a much more aggressive and sporty look to the front end. Now that you have some background knowledge about this front-end conversion, you can continue to find the process easier.

The conversion involves replacing the front bumper, hood, fenders, headlights, and potentially the front core support. Because of the difference in the shape of the front end, this is not a direct bolt-on project. The main goal is to replace the parts of the E90 that differ from the E92 front end. This can be a challenging task for anyone not familiar with car repair. But with the right knowledge, this conversion is possible, and the results are pretty satisfying. Also, since you are changing many parts of the front end, you can consider this a good opportunity to update other things while you are at it, such as headlights and a new bumper. You also have the chance to add some aftermarket components.

Required Components for the E90 to E92 Conversion

Okay, so what exactly do you need to do this E90 to E92 front end conversion? The parts list might seem a little intimidating at first glance, but don't worry, we'll break it down. Here's a comprehensive list of the primary components you'll need:

• E92 Front Bumper: This is the most obvious and defining piece. Make sure you get the correct style for your E92 (e.g., pre-LCI or LCI, M-Sport, etc.) and it will match the look you want. Also, remember to get a bumper that fits your car, depending on the production year, they will fit differently.
• E92 Headlights: These are essential. The E90 and E92 headlights have completely different shapes and mounting points. Again, consider the style (pre-LCI or LCI) and if you want to upgrade to aftermarket headlights while you're at it, now is a great time!
• E92 Fenders: The fenders are also different between the two models. They curve differently to accommodate the E92 headlights and bumper. Don't forget to grab them!
• E92 Hood: The hood design is also different to accommodate the different headlights and front end.
• Front Core Support (Optional but recommended): The core support might need modifications or replacement. Some people have found ways to make the E90 core support work, but using the E92 core support often simplifies the process and ensures a cleaner fit. Also, you can change the core support based on your needs.
• Grilles: The E92 has different kidney grilles.
• Fasteners and Hardware: You'll need various bolts, screws, and clips. It's a good idea to have some spares on hand, as you might break some during the removal and installation.
• Wiring Adapters (Potentially): Depending on your headlights, you might need wiring adapters to make the headlights function correctly. These are very important to make sure the headlights will actually work. Make sure to consider the plugs to plug them in, or consider the aftermarket one if you want to upgrade your car with fancy lights.
• Underbody Panels and Wheel Well Liners: These might need to be modified or replaced to fit the new front end.

Where to Source Your Parts

You have several options when sourcing these parts. You can go with genuine BMW parts from a dealership. This will ensure the highest quality and perfect fitment, but it's also the most expensive option. Another option is to go to a salvage yard or a used parts marketplace, where you can find used OEM parts at a fraction of the cost. Always inspect used parts carefully for damage before purchasing. Lastly, you can get aftermarket parts, which can offer a balance between cost and appearance. Make sure to research the quality and fitment of any aftermarket parts before buying them.

Step-by-Step Guide to the E90 to E92 Front Conversion

Alright, let's get into the nitty-gritty of how to perform this E90 to E92 front-end conversion. This is a general guide, and the specific steps might vary slightly depending on the exact parts you have and the condition of your car. However, it should give you a good idea of the process. Always prioritize safety and take your time.

1. Preparation and Safety: Before starting any work on your car, disconnect the negative terminal of your battery to prevent electrical shorts. Gather all your tools and parts, and make sure you have a clean and well-lit workspace.
2. Remove the E90 Front Bumper: Start by removing the front bumper. This typically involves removing screws and clips from the top, bottom, and sides of the bumper, as well as disconnecting any wiring for fog lights or parking sensors.
3. Remove Headlights: Remove the headlights by unscrewing them from their mounting points and disconnecting the wiring harness. This is the opportunity to remove the old lights and prepare for the new ones.
4. Remove Fenders: Undo the bolts and screws that secure the fenders to the body and the inner fender wells. Be careful when removing the fenders, as they can be delicate and easily scratched. With the fenders removed, you will notice the differences between the E90 and E92 models.
5. Remove Hood: Open the hood and remove the bolts that secure it to the hinges. You might need an extra pair of hands to support the hood as you remove it. This also gives you the chance to see how different they are.
6. Modify or Replace Core Support (Optional): If you're replacing the core support, this is the time to do it. If you're modifying the E90 core support, you'll need to cut and/or drill to fit the E92 components. This is one of the more involved steps and requires careful measurement and cutting.
7. Install E92 Fenders: Mount the E92 fenders, making sure they align correctly with the body and the hood. Tighten the bolts and screws.
8. Install E92 Hood: Mount the E92 hood and align it with the fenders. Adjust the hinges to ensure a proper fit.
9. Install E92 Headlights: Install the E92 headlights and connect the wiring harness. If you're using wiring adapters, connect them now.
10. Install E92 Front Bumper: Install the E92 front bumper, making sure it aligns with the fenders, headlights, and any other components. Reconnect any wiring for fog lights or parking sensors.
11. Install Grilles: Install the kidney grilles.
12. Final Checks and Adjustments: After installing all the components, double-check all bolts and screws to make sure they are secure. Adjust any panels or components as needed to ensure a perfect fit.
13. Reconnection and Testing: Reconnect the negative terminal of the battery. Test all the lights and other electrical components to make sure they are working correctly.

Tips and Tricks for a Successful Conversion

• Plan Ahead: Before starting the conversion, research the process thoroughly and make sure you have all the necessary tools and parts.
• Take Your Time: Don't rush the process. Rushing can lead to mistakes and damage to your car.
• Label Everything: As you disassemble your E90, label all the bolts, screws, and clips to make it easier to reassemble everything.
• Take Pictures: Take pictures of each step of the process. This can be helpful if you run into any problems during reassembly.
• Get Help If Needed: Don't be afraid to ask for help from friends or online forums if you get stuck.
• Test Fit: Before painting your new components, test-fit everything to make sure it fits correctly. This can save you time and money.
• Body Shop: It's better to bring your car to a professional body shop if you have no experience with car modification.

Post-Conversion Considerations

Once you've completed the E90 to E92 front-end conversion, there are a few things to keep in mind. You might need to get your car aligned after the conversion, as the new components could affect the alignment. Also, you'll need to decide what to do with your old E90 front-end components. You could sell them, store them, or dispose of them. Finally, remember to maintain your car properly after the conversion, as with any modification.
