JUST labor? well depending on the shop your looking around 80$USD/hour. and to replace a 3sgte in a turbo is book time of 14 hours. your going to be doing that plus adding a few things, having to replace the rear axles too, and new ecu and get the wires through the firewall, new fuel pump, mount new exhaust, your looking closer to 20. thats if you even have all the parts, including all the hiddon costs and things you dont think about.
Im at 1200 and still waiting on axles, but im getting wholesale rates through my work
if your deciding to buy turbo or a N/A and do a swap, buy a turbo. it will cost about as much to do a swap as if you just bought one in the first place. plus the cost of the N/A. If you already have an N/A or got a good deal on one, plan one spending close to 5k less you do your own labor
