If you’re thinking about swapping the engine in your Mazda Miata with a GM LS1, you’re definitely not alone! This mod has gained a lot of traction in the car community, and for good reason. The LS1 is known for its impressive power and reliability, and pairing that with the lightweight Miata chassis can result in an exhilarating driving experience.
What You’ll Need
Before jumping into the swap, it’s essential to know what parts you’ll require:
LS1 Engine: Make sure it’s in good condition, ideally with low mileage.
Miata LS1 Swap Kit: These kits vary in complexity, ranging from basic muscle parts to complete kits that include motor mounts, oil pans, and more.
Transmission: The factory Miata transmission may not hold up to LS power, so consider a compatible transmission.
Cooling System: A larger radiator is important for handling the increased heat.
Wiring Harness: A standalone harness can simplify the integration of the LS1 in the Miata.
Performance Benefits
Swapping an LS1 into your Miata can transform the car’s performance:
Power-to-Weight Ratio: The weight of the Miata combined with the power of the LS1 results in a crazy power-to-weight ratio.
Aftermarket Support: There are plenty of aftermarket performance parts available for both the LS1 and Miatas, enhancing your build even further.

Have any of you completed this swap, or are you in the process? I’d love to hear your experiences, challenges faced, and which swap kits you recommend! Let’s share and help each other out in this awesome automotive journey.
The LS1 engine is a 5.7L V8 that delivers around 350 hp and 365 lb-ft of torque. Its lightweight design makes it ideal for a Miata swap. You’ll get a huge boost in power while keeping the car nimble!
Yes, the LS1 is approximately 100 lbs heavier than the Miata’s stock engine, but the power gain is unmatched! Plus, you can modify the LS1 for even more horsepower.
The only real challenge was aligning the engine mounts correctly. Other than that, it was straightforward with the kit’s instructions! Just make sure you have a good set of tools.
You’ll need a larger radiator, and modifying the cooling fans is crucial. There are aftermarket kits specifically for LS1 swaps that simplify this process.
I’ve been eyeing the LS1 swap kits for my Miata too! The most popular options seem to be the Flyin’ Miata and the V8 Roadster kits. Each has its pros and cons, so it’s good to check the reviews before deciding.
