Seeing as the Scion TC has been discontinued for some time now, compatible turbo kits are becoming increasingly harder to find—expect to pay somewhere between $1,000 and $3000, if you’re able to find one.
We recommend checking secondhand-seller sites like eBay for turbo kits compatible with the 2011 Scion TC—most of the kits you’ll find there cost between $1,000 and $2,000.
If you have the cash to spend, however, you might opt for the 2011 Scion TC turbo kit produced by Vivid Racing, which is priced at a whopping $6,000.
