Datsunworks KN20 DOHC cylinder head for Datsun 240Z!

Z Car Garage is excited to collaborate with Datsunworks to develop their KN20 DOHC cylinder head for the Nissan inline-6 L-Series engine. This is a Honda K-series derived cylinder head with superior flow rates and modern valvetrain components effectively transforming your SOHC L-series into a high-revving DOHC engine. We have installed the Datsunworks head into our client Gary's Datsun 240Z and it is currently in the tuning/testing stage. In conservative tune it made 350hp/248tq at the wheels. This video shows multiple dyno passes and street driving to give you an idea of how sounds and performs. Turn those speakers up and enjoy!
