If you can dream it, Motorsport Enterprises Racing has the expertise to build it. If you are thinking about racing the Street Touring Unlimited Class, we design all our motor swaps with the driver in mind. One of the fastest ways to change your street ride into a true “super car” is to swap engines. MER’s background in Mazda performance makes us the perfect shop to drop an LS1 into your Miata. When you start this you need someone that has done this before to get you on the right track, MER has experience to save you a lot of experimentation. We have done it before from LS3 V8’s in a Miata, LFX V6 engine in an RX8, LS1 V8 engine in an RX7.
You name it, we have already built it!

After we tackle the technical challenge of fitting the motor we have the electronics expertise to make it reliable and street-able. We can fit an ECU to match the new engine and wire it into the existing harness or build you an entirely new wiring harness if you are going full race.

As part of any motor swap, we also suggest having our suspension tuning experts make the necessary adjustments to the suspension to compensate for the new weight bias or additional weight. After all, you are going to need good handling to harness all of that horsepower.

Call today to discuss the possibilities!

We work on all things fast but we cut our teeth on high-performance Mazdas. With years of experience, we’ll get every ounce of performance out of your Mazda. We have the ability to perform compression test on rotary engines, handy for Formula Mazda cars. Compression numbers can be separately seen for all rotor faces. The device also corrects for the Mazda specified cranking rpms of around 250. Before you buy a rotary, we highly suggest getting it tested.

• Compression testing – $100
• Full rotary inspection with pre purchase inspection – $150.

Suspension tuning is an art, when you experience a car with the suspension tuned by MER you will wonder why you did not get this done sooner! MER does not rely on a fancy alignment machine, we do everything old school but our setups are hard to beat.

• $150 for an alignment (most cars)
• $395 for setups which includes corner balancing and cross weight (most cars)
