Introduction

Does anyone here have experience with the BMW E90 LS swap kit? I’ve been considering this project for some time and wanted to gather insights, experiences, and recommendations. Swapping a Chevrolet LS engine into the BMW E90 seems like a great way to boost performance, but I’m curious about the specifics.

Why an LS Swap?

Swapping out the original BMW engine for an LS engine is a popular modification in the automotive community due to several reasons:

  • Power: LS engines are known for their high power output and tuning capabilities.
  • Weight Distribution: The LS engine offers a good weight distribution which can enhance handling.
  • Parts Availability: LS engine parts are readily available and more affordable than custom BMW parts.

What to consider before starting the swap

Before diving into the swap, keep these points in mind:

  • Budget: Make sure to account for the kit cost, engine purchase, and any additional modifications.
  • Legal Regulations: Check local laws regarding engine swaps to ensure compliance with emissions and safety standards.
  • Skill Level: Assess whether you’re taking this on as a DIY project or if you need a professional shop’s assistance.

Installation Steps Overview

While the process can vary, here’s a basic outline to give you an idea:

  1. Preparation: Gather all the necessary tools and parts.
  2. Engine Removal: Safely remove the stock BMW engine.
  3. Fit the LS Engine: Position the LS engine in place using the swap kit mounts.

I’ve done a lot of research on LS swaps and there are several great options, like the LS1 or LS3. The LS3 provides around 430 hp, making it a popular choice for performance enthusiasts.

I agree! The LS3 is fantastic, but don’t overlook the LS7 for even more power as it can push close to 500 hp! It’s perfect if your budget allows.

Deciding between LS engines really depends on your goals. For daily driving, an LS1 is usually more than enough, while the LS9 is a great choice for a track car — if you can handle the price tag!

What about the LS2? It’s often overlooked but provides solid performance at a better price point, making it a good middle ground for budget builds!

The key is balance! Assess your budget, and determine if you’re going for power or reliability. A well-tuned LS1 in an E90 can still be a beast without breaking the bank.

True! I’d add that drivetrain compatibility is important too. Some LS engines come with better aftermarket support for swaps.

I’m really keen on the E90 swap, but how hard is the installation? Is it mostly plug and play or will I need custom components?

It’s a bit of both! You’ll definitely need some custom mounts and wiring, so be prepared for that if you’re not super handy.

One thing I love about the LS engine family is that there’s a great community around these swaps. Tons of tutorials and forums to help with whichever route you choose!

Absolutely! And they’ve got that aftermarket support to help with everything from tuning to installation kits, which is crucial for a E90 swap.

Cost is a big factor for many of us. For high performance on a budget, the LS1 or LS6 are compelling choices—they offer solid power without being exorbitant on the used market.

You have a point! Just remember, to get the most out of those cheaper engines, you might need additional investment in parts or tuning.

It’s exciting to think about how many different builds you can create with an LS swap! The performance potential is enormous, especially in the lightweight E90 chassis.

15

It sure is! I’ve heard people joke that if you want an LS in everything, just start with the E90 and let your imagination run wild!

16

I’ve been looking into LS swap kits for my E90 too! The typical components include engine mounts, headers, and a custom oil pan. What else should I consider?

17

Great list! You might also need a transmission adapter, cooling system upgrades, and wiring harnesses specific for the LS engine.

It’s essential to have a good range of tools. A torque wrench, engine hoist, and a socket set are must-haves. Any recommendations on brand?

19

Absolutely! A standalone ECU or a factory wiring harness can really simplify the wiring process.

Don’t forget to factor in a new fuel system! The LS engine will require different fuel pump and lines to handle the power.
