The episode of Jay Leno's Garage focuses on several restoration projects. The host, Jay Leno, discusses an aerial project where he replaced the original General Motors Ecotec four-cylinder engine with a custom motor built by a friend. This new engine uses two Hayabusa motorcycle heads on a bespoke crankcase and is connected to a Sadiv French six-speed transmission. The aim
1. The text discusses a project to restore a classic car, specifically a Saab Aerial item, with a focus on improving its performance and durability.
2. The original engine was a General Motors Ecotec four-cylinder engine with an estimated 200 horsepower.
3. The engine was replaced with a custom-built motor using two Hayabusa motorcycle heads and a bespoke crankcase. This new engine produced 488 horsepower on the dyno.
4. The transmission used in the project was a Sadiv French six-speed, which was significantly lighter than the original transmission in the car.
5. The chassis of the car was strengthened to accommodate the increased power of the new engine.
6. The project also involved modifying the car's doors and windows to reduce noise and vibrations, aiming for a near-silent driving experience.
7. The car's interior was rebuilt using new materials and components, including a larger radiator, chassis braces, and engine mounts.
8. The project also involved restoring a Corvette with a 327 fuel injection engine, using Molly Pistons and roller lifters.
9. The text also discusses the restoration of a Stanley Steam Car, a complex project involving a multi-year effort and the creation of new parts from plans and existing components.
10. The text mentions the use of a brand new boiler for the steam car's engine, indicating the level of detail and precision required for this project.
11. The project included the replacement of the car's throttle, which was found to be broken and causing water to leak into the engine.
12. The car's steering system was also updated, with the throttle control wheel being replaced with a smaller steering wheel.
13. The text discusses the restoration of a motorcycle that was involved in an accident, with the project focusing on repairing and replacing damaged parts rather than fixing the accident damage.
14. The motorcycle's original chrome forks were replaced with new ones due to the risk of hydrogen embrittlement, a process that weakens metal during the chroming process.
15. The project involved replacing the motorcycle's springs, bearings, and leaf spring, with new components being used for the rear wheel due to its heavier weight.
