Nissan 350z turbo kits are extremely diverse in both quality and cost. You can find some simple turbo kits for as little as $1,100. But it’s more common to see kits in the $4,000 to $8,000 range—and not at all unusual to come across a few that are worth over $10,000, the AAM EFR Twin Turbo Kit is a perfect example. It all just depends on the type of parts that you’re buying and the performance improvements that they provide.
