That pic licks monkey balls. I cannot tell, but here are a few tips

1) if its a Duster its a 3.0L
2) Turbo buldge hood doesn't necesarily mean turbo engine in the newer ones, I have seen more than a few stock ES NA ones with it, and the V6's also have it.
3) Sundance RS, is you happen to come across one, is a turbo.
