Anyone Done an E36 BMW LS Swap? Let's Share Tips!

Introduction

Are you thinking about doing an LS swap in your BMW E36? You’re not alone! The E36 chassis is a popular choice for enthusiasts looking to enhance their car’s performance, and swapping in a powerful LS engine can make a significant difference. This post aims to compile useful tips, resources, and personal experiences to help anyone who’s ready to take on this exciting project.

Why Choose an LS Swap?

  • Power Upgrade: LS engines offer a fantastic power-to-weight ratio and are known for their performance.
  • Parts Availability: The LS platform has a wide range of aftermarket parts available, making upgrades and repairs easier.
  • Engine Reliability: LS engines are praised for their durability and reliability, which is crucial for a project car.

Getting Started: What Do You Need?

Here’s a list of essential components and tools to consider before you dive into the swap:

  • Engine and Transmission: Choose the right LS engine and transmission combo that fits your power goals.
  • Swap Kit: Look for swap kits designed specifically for E36 BMWs. They typically include motor mounts, transmission mounts, and sometimes even wiring harnesses.
  • Fuel System: Upgrading the fuel system is crucial. You may need a new fuel pump and lines to handle the demand of the LS engine.
  • Cooling System: Ensure you have a suitable radiator and cooling fans to keep your engine temperatures in check.
  • Exhaust System: Custom exhaust headers will likely be required, along with a new exhaust system to fit your E36.

DIY or Professional Help?

Deciding whether to tackle the swap yourself or hire professionals depends on your skill level and available tools. If you’re experienced with automotive work and have access to a garage, doing it yourself can be a rewarding challenge. However, if you’re uncertain, seeking help from a professional can save a lot of headaches.

Documenting Your Swap

It’s always a great idea to document your swap process. Capture the work in progress with photos and notes – not only is it useful for future reference, but it also contributes to the community! Sharing your journey can inspire others looking to take on a similar project.

Let’s get swapping!

Great topic! For E36 swaps, the LS1 is a popular choice. It offers a good balance between power output and weight. Just make sure to consider the cost of a proper transmission and mounts.

I’ve heard that the LS3 is also a solid option if you want more horsepower! It might be slightly heavier, though.

Speaking of weight, does anyone know how the LS options compare with the stock E36 engine? I want to keep the handling intact.

LS3 is fantastic, but don’t forget about budget constraints. Sometimes, you can get a good deal on an LS1 and modify it.

For me, I opted for the LS2. It’s a good compromise between power and weight, and upgrades are available for those who want more speed later!

That’s really helpful, everyone! I think I’ll go with something less common but still affordable, maybe an LQ4? Has anyone used that?

The LQ4 can be a great choice! Just be sure to get a good tune and proper headers. It can make more torque than you think!

After considering power output and costs, I think I’ll stick with LS1 but swap in a different intake manifold for better performance. What do you guys think?

Sounds like a solid plan! The right intake can really wake up an LS1 without breaking the bank. Just remember, reliability matters too!

Why not just drop in a V10 instead? I mean, it would definitely stand out! Just kidding… but seriously, make sure your cooling system can handle that LS heat.

Haha! A V10 would be wild! But in all seriousness, what kind of cooling upgrades do you recommend for an LS swap?

I just finished my LS swap on an E36 last month! First, you’ll need a solid set of tools: a lift or jack stands, engine hoist, and basic hand tools. Start by stripping the bay down to the essentials. It really makes the swap easier!

That’s awesome! Did you have to make any major modifications to the engine bay? I’ve heard it can get tight with the LS engine.

Yes, you’ll definitely need to modify the engine mounts. I used solid mounts from a swap kit which helped a ton. Also, make sure to clear out the firewall for extra space. It’s a game-changer!

Sweet, I’ll look into that! What do you recommend for updating the cooling system? I’m worried about overheating issues.

Great question! I recommend using an LS-specific radiator. It’s much more efficient, and don’t forget a good set of fans to help with airflow. Trust me, it makes all the difference!

Thanks for the tip! How about the wiring? I’ve heard that’s a headache.

Wiring can be tricky but not impossible! Look for an adapter harness to make it easier. You’ll also need to repin the original BMW harness. It sounds tedious, but it’s manageable with patience!

Patience? What’s that? Haha! But seriously, adapters seem like a good idea to keep it clean.
