Hey man don't get me wrong i'm not hating on your project at all. i think its awesome that you're wanting to do something so out there! i'm just making sure you're aware of what you're getting into. all the cars i've listed can be had for around $1000 to $1500. and when you do a swap like you want to, you're going to have to go through everything anyway.
If you're dead set on the del sol then by all means do it! Just know there are better starting points for what you want to do. But if/when you do the del sol it will be awesome.
