In principle, providing they are both post-86 cars, yes. The engine block is the same, but I imagine the plumbing for the Turbo and issues like wiring may cause you some thought. Likewise, you will need to think about uprating the brakes in particular (though this is pretty simple - the vented front discs and solid rear discs from a Turbo bolt straight on to replace what I'm assuming is a disc/drum set up on the Symbol). Others will know considerably more than me, I imagine.
