All you need is a 280zx turbo donor, or just the turbo, injectors, ecu, harness, exhaust manifold and oil pan. thats 180 hp stock, crank up the boost and you can get 200 whp pretty easy, add an intercooler and you can get about 250 whp. any more than that and you'll need to upsize injectors and deal with some sort of upgraded management, and likely head studs, and MLS gasket. Or you can get some dumpy v8 of your choice and a spool of welding wire and get to work.
