Rotary Engine Rebuilds

Rotary Engine Rebuilds are what we do best. Whether you want a stock rebuild or a full out peripheral port monster – we can do it. Over 20 years of experience and innovation had made Chips Motorsports the “go to” when you want a truly special motor. Regardless if it’s a 12A, 13B, 20B or 26B our attention to detail and precision methods ensure your rebuild is ready to go day one – no break-in required!

Everything starts out with a “Basic” rebuild and goes from there. But there’s nothing “Basic” about our rebuilds. In addition to replacing wear and tear items, we meticulously remove each and every bracket, bolt and component – so we can media blast, clean and replate to OEM spec (or better!).

The options for rotors, housings, plates and modifications are virtually endless, so once you purchase a rebuild – spec’ing out everything needs to be done by contacting us direct. However, we want to showcase some of our options and innovations so you know what’s available and can make a educated decision about what’s right for you.

Rotary Engine Rebuild FAQs

Stock or Modified?

Deciding on what’s right for your rotary engine rebuild and vehicle needs to be step 1. Do you want a “restoration” maintaining all stock systems? Or do you want a ported monster for standing mile racing? Most likely, something in between – only you can decide – but we can get you there.

12A? 13B? Renesis? 20B? 26B?

We rebuild ALL Mazda Rotary Engines. 1st Gen 12A engines, 2nd Gen 13B T2 & N/A engines, 3rd Gen 13B-REW engines, RX-8 RENESIS engines and Cosmo 2 & 3 Rotor engines. If it’s got a spiny triangle dorito thingy – we’re into it. We also build with quality and longevity that will surpass factory Mazda engines.

To Port or Not to Port?

Porting is a common upgrade when rebuilding a motor. Since rebuilding a motor doesn’t happen frequently, the only time you can get porting done is while it’s apart. However, there are MANY rotary engine port options which provide drastically different results. You should familiarize yourself with them by reading: About Rotary Engine Porting.

What if I don't have a good core?

All our prices are based off customers supplying a good core with usable rotors, housings and irons. In the case of a “refresh” on a high mileage motor – things are generally reusable. However, a rebuild due to catastrophic failure usually requires new core components. If your build requires these, we will let you know and offer options for refreshing used parts or supplying new.

What are you putting in my motor?

We use brand new OEM Mazda seals, springs & o-rings. Period. End of story. We don’t have a “parts bin” where we pull used “acceptable condition” parts from other motors and use those on your motor. In the case of rotors, irons and housings – we will use your components if they are in good shape or can be reconditioned. Otherwise, we use new OEM Mazda components.

How about the warranty?

All our motors come with a 12-month warranty – and will cover any mistake or failure due to improper rebuild.

How do I get my motor to you?

First off, you’re gonna have to pull it and strip it. We ONLY need the short block. Then you need to secure it to a pallet and wrap it to protect it from the elements. From there, contact us and we can arrange for discounted shipping to us (and back to you once we’re done). You also have the option of dropping off your car for a swap, but again, contact us to setup an appointment.

I'm still not sure what I want.

Call us. E-mail us. Hit us up on Facebook. Shoot over a contact form on our website. We know these are big decisions and you will have questions / want advice. We’re here to help you figure it out.
