Engine Builds
At JM Imports, we’re not simply assembling engines — we’re creating precision-engineered performance builds. Our team of highly skilled specialists brings together over 80 years of combined experience, ensuring every engine we produce meets the highest standards of quality, durability, and performance.
When it comes to serious power, our custom-built engines operate in a class of their own. From GTR powerplants to McLaren applications, each build is engineered for maximum output. We offer solutions capable of delivering 2000+ bhp, as well as more restrained yet still exceptional builds producing 1000+ bhp, tailored to the customer’s needs.
Every component — from pistons and internal hardware to turbochargers and supporting systems — is carefully specified, matched, and assembled to withstand extreme power demands without compromising reliability, drivability, or efficiency.
At JM Imports, we are committed to pushing the boundaries of automotive engineering, consistently delivering engines that are not only built to perform, but engineered to excel, endure, and outperform the competition.
If you’re considering an engine build, please get in touch by email and we’ll be happy to discuss the process, specifications, and requirements needed to achieve your performance goals.
