at the moment ive got an nb miata with a little bit of work done to it. i like to drive it and all. but im wanting something with more room and luxury. so i put an ad up on craigslist trying to sale the miata. someone contacted me with a 1986 audi quattro 5000 cs wanting to trade. i like the look of the quattro and all but im trying to figure out what it would take to make it safely to 400 whp?
