I am thinking about re-doing the rex I have parked outside my house. I drove it the other day and realized its so much more fun to drive than newer cars. Only thing is I don't want to put a lot of money into it because you can't get the money back. So I'm wondering whats the best route. The engine in there is so-so, but the tranny is shot. I am thinking of just pulling them both out and putting in another d16a6 and just swapping it myself -- I figure I can probably get a decent price on one. Or does it make more sense to rebuild what I already have? I'm thinking of a budget of about 1000, is that realistic?
