One of my friends is asking me how much he is looking to spend on a ls+turbo, that is fairly reliable and needs not to be crazy fast, and what is a good setup.

 

$600-$1500 for a complete ls swap depending where you get it
$800-$4000 for a complete turbo setup depending on whether you build it yourself or buy it complete from a company.

total $1400 - $5500.

when going FI, be prepared to empty your pockets
