depends what you're doing with the car mate. If it was track orientated then you could to loads to it. Road wise, maybe change all the rubbers on the ARB/wishbones/subframe. Clean up the bay. Wrap the manifold, get the inlets ported, remove the AC. etc. Loads of things, but depends what you're after. If the belts haven't been done, getting them done before putting it back in would be a good idea, maybe the water pump also.
