Datsun Spirit & Jenvey Dynamics collaboration manifold setup for Datsun L28 engine. 2 years in the making with countless hours of R&D and testing. This setup is to go with our Stage-4 or Stage-5 engines with big intake ports for a serious power, a motorcycle like super fast rev response, and Formula car type wicked sound. Works for Natural Aspirated as well as Turbo.
The base kit is for manifold and NPT allen plugs only. The DSI kit comes with the base kit plus the DSI Big port manifold gasket (which is a perfect match to the manifold), and correct Japanese OEM style bolts and hardware.
