The Cayman GT4 gets a turbo kit for its opposite-six engine

The 981c Porsche Cayman GT4 ships with a six-cylinder mill rated at 385 hp (287 kW) and 420 Nm (332 lb-ft). If this doesn’t impress you, consider asking HP Import for an upgrade.

Chip tuning seldom works well (or at all, for that matter) with naturally aspirated engines, so the tuner decided to try a different approach and fit it with a 5-6 psi turbo kit. The numbers are not that big by modern turbocharger standards, but they are apparently enough to boost the output to 450 hp (336 kW) and 475 Nm (350 lb-ft).

HP Import says it is not going to call it a day just yet. Instead, the team is currently looking into making the powertrain stable enough for 500+ hp (375+ kW).
