you have an oxymoron in the thread title.. the words project and daily-driver are opposites like thundery scilence or awesome daewoo
seriously... if you want to build a turbocoupe.. do it, they are supercool.. just know that projects make very bad daily drivers (you cant drive them when they are appart) you will sink alot of money into somthing with low intrinsic resale value (ask me how i know.. pro touring 79 malibus dont sell real well) and you will take time (and money) away from your other projects.... unless you are jay leno ofcourse...
