If it helps, I've put 10-11k on mine in 5 months or so with no reliablity issues (std apart from wheels, full blend and toothies). It needs a lot of stuff done to it to bring it back up to a good standard (I have all the bits just not got round to sorting it). The thing to do is concentrate on making it a nice car to drive as opposed to chasing daft power figures and make it look stunning, get the fundamental bits right and build on it from there. You can always do stuff like swap suspension and wheels in 2-3 hours, get it running and legal and you'll suddenly have a huge new love for it!
