If it's like my engine then, you couldn't get a whole lot out of it. My engine still pulls really hard and never gives my problems, but 1-2nd and 2nd-3rd syncros are jacked and the main seal is broken so it leaks oil. It would cost more to fix those couple of things than to buy a new engine(it's a D16a6). I mean, it still runs really well but I am sure no one would buy it.
I am going to buy a junky 4g sedan and put it in there, and use it for trails and having fun after it rains
