conversion was pretty simple.. cut off stock mounts on crossmember.. mock up motor and trans ... build mounts, i used volvo hockey puck style rubber mounts with stud going through it. Made a transmission mount.. used a s13 240sx sr20 radiator, found some hoses to work, got drivline made, mounted a 14 inch pulled slightly offset inside engine bay, you wont have issues with stock exhaust manifold hitting any type of steering box obvioulsy like i had to keep in mind. mod the s13/s13 sr20de harness to make it standalone type deal to wire up in datsun. I also did a baffle in my coupe fuel tank and made a new 5/16th feed line for fuel considering the original was 1/4 inch. I also ran a inline datsun 280z fuel pump. :)
