You’re not just buying a box of parts - you’re buying an engine swap solution

With over 20 years of experience in mechanical and systems engineering, including the development of complex products for the aerospace industry, our team has the knowledge and expertise to produce engine swap solutions that always perform perfectly for you. 

All our kits are engineered to fit right the first time around so you can achieve a seamless engine swap. Our kits come with detailed instructions too, and our team is always there to provide you with the support you deserve.

We know how much you love working on your car, but we also understand how much you love to drive it.

You get the support to go with them.
