Mazda MX-5 NA / NB – 1UZ / 3UZ Engine Swap Kit V3 - Cybul

Mazda MX-5 NA/NB 1UZ / 3UZ V8 Engine Swap Kit V3

Do you want to install a Toyota 1UZ or 3UZ V8 engine in a Mazda MX-5 NA or NB? This Cybul Engine Swap Kit V3 provides a very complete mechanical basis for a V8 swap into the compact MX-5 chassis.

A 1UZ or 3UZ swap into an MX-5 normally requires a lot of custom work on the engine position, oil pan, subframe, engine mounts, and exhaust clearance. This V3 kit takes a large part of that work off your hands. The set includes, among other things, a modified oil system, heavy-duty engine mounts, a chromoly tubular front subframe, and specially developed exhaust manifolds for the Toyota UZ V8 engine.

The kit has been developed for serious street, drift, track day, and performance builds where a strong V8 base is desired. The modified subframe, the included engine mounts, and the modified oil system create a neat and sturdy basis for placing the Toyota V8 in the MX-5 NA/NB chassis.

This is not a fully plug-and-play complete package where the entire swap can be completed without additional parts. Components such as the engine, gearbox, clutch, driveshaft, cooling system, exhaust system after the manifolds, ECU, wiring harness, and tuning still need to be assembled to match the chosen setup. However, this kit saves a lot of mechanical custom work compared to a fully self-built project.

The Cybul V3 swap kit is therefore particularly interesting for builders who are looking for a strong and well-thought-out basis for a Toyota 1UZ or 3UZ V8 swap, but want to retain the freedom to assemble the rest of the drivetrain, electronics, and finishing as desired.
