The Lexus RX300’s 3.0L V6 1MZ-FE engine, known for its reliability and smooth power delivery, has found its way into a variety of vehicles beyond its original home. One such application, documented by UK-based Woodsport, is a unique engine swap into a Toyota MR2 Mk2. This Lexus Rx300 Modified project showcases the potential of this engine in a lightweight sports car platform.
The Woodsport Lexus RX300 MR2 Mk2 Build
Woodsport, renowned for their expertise in Toyota engine conversions, embarked on a project to create what they believe to be the UK’s first Lexus RX300-powered MR2 Mk2. The project involved extensive modifications, including a complete engine bay restoration and respray.
The original 3S-GE engine was removed, and the engine bay was meticulously prepared to accommodate the larger 1MZ-FE V6. The engine itself was not simply dropped in; it underwent a thorough overhaul and rebuild before being painted to show-car standards.
Furthermore, the MR2’s S54 gearbox was disassembled, fitted with a Limited Slip Differential (LSD), and enhanced with Woodsport’s signature 5th gear extension. This comprehensive approach ensured the drivetrain could handle the increased power and torque of the Lexus V6.
Performance Considerations: Torque Takes Center Stage
The 1MZ-FE VVTi engine in this lexus rx300 modified build produces approximately 210bhp and a substantial 222 lb-ft of torque, available from 4000 rpm. This torque figure surpasses even the stock 3S-GTE turbocharged engine found in other MR2 variants.
Woodsport highlighted the 1MZ-FE’s superior torque curve compared to various Toyota engines, demonstrating its potential for impressive acceleration and responsiveness. While horsepower figures are important, the abundant torque makes this a particularly compelling engine swap for the MR2. The low-end torque provides significant improvements in drivability.
Custom Fabrication: Intake and Exhaust Challenges
The project required significant custom fabrication, particularly for the intake and exhaust systems. The RX300’s stock manifolds proved incompatible with the MR2’s chassis, necessitating a creative solution. Woodsport utilized a rear bank Camry manifold on the front bank and a front bank RX300 manifold on the rear, demonstrating their ingenuity.
A custom dual intake pipe was also fabricated to optimize airflow to the engine. This intricate piece, a testament to Woodsport’s craftsmanship, addressed the unique challenges of fitting the 1MZ-FE’s intake system within the MR2’s engine bay.
From Concept to Reality: A Two-Week Transformation
Remarkably, Woodsport completed this complex engine swap in just two weeks. This rapid turnaround speaks to their experience and deep understanding of the vehicles involved. The project culminated in a successful first start-up, with the Lexus V6 roaring to life in its new home.
Conclusion: Lexus RX300 Modified – A Testament to Ingenuity
The Woodsport Lexus RX300 modified MR2 Mk2 stands as a unique example of automotive ingenuity. By transplanting the reliable and torque-rich 1MZ-FE V6 into the nimble MR2, they created a compelling blend of performance and practicality. This build not only showcases the versatility of the Lexus engine but also highlights the skill and dedication required for such ambitious engine swap projects. The custom fabrication work, especially the intake and exhaust solutions, further underscores the level of expertise involved. This lexus rx300 modified MR2 serves as inspiration for enthusiasts seeking alternative engine options for their vehicles.
