73 Duster here. I mounted mine further to the passenger side than Dizuster and have a smaller framed 78/75 T4 turbo than his S400. Flipped magnum manifolds, relocated alternator to driver side, and a remote oil filter to sneak the downpipe through. No cutting of anything. The junction off the passenger manifold to the turbo inlet merge probably isnt ideal, but it'll work for my goals. Microsquirt with LS throttle body/coils/sensors and a crank position sensor from SD Concepts on the board here.
