Ep 23. Engine Masters meets the Roadkill Rotsun Turbo 5.0!

Engine Masters season 2 episode 23, titled "Engine Masters meets the Roadkill Rotsun Turbo 5.0!" is an exciting episode where the hosts of the show, David Freiburger and Steve Dulcich, team up with Mike Finnegan and Tony Angelo from Roadkill to work on a turbocharged 5.0-liter engine. The engine belongs to the famous Rotsun, a 1971 Datsun 240Z that has been heavily modified by Roadkill.

The hosts of the show start by removing the engine from the car, which is a task in itself given the number of modifications done to it. Once the engine is on the stand, they begin to take it apart and inspect it to see how it has been modified. They find that the engine has a lot of FORD parts in it, which is not surprising given that the Rotsun has a Ford 5.0-liter engine in it. They also find a lot of custom-made parts, such as the turbo system and the intake manifold.

Once they have inspected the engine, they start to work on it. They upgrade the head gaskets to improve the engine's sealing and replace the old headers with a set of custom-made ones. They also install a new intake manifold and throttle body to improve the engine's flow. They then turn their attention to the turbo system, which they find has a lot of problems. They fix the problems by upgrading the wastegate and installing a new blow-off valve.

The hosts then move on to the fuel system. They upgrade the fuel injectors and fuel pump to be able to provide more fuel to the engine. They also upgrade the ignition system with a high-performance coil and plug wires to ensure the engine is getting the right amount of spark. Once the upgrades are done, they put the engine back together and test it.

The testing is done at Westech Performance Group, where the engine is put through a rigorous dyno test. The hosts are excited to see how much power the engine can make, and they are not disappointed. The engine makes an impressive 1,000 horsepower and 800 lb-ft of torque, which is more than enough to power the Rotsun.

Overall, Engine Masters season 2 episode 23 is an exciting episode that showcases the skills of the hosts and the collaboration between the two shows. It is a must-watch for anyone who is interested in high-performance engines and the work that goes into building them.
