Those famous Nürburgring Porsche racing heroes have unveiled a Manthey Porsche 997 GT3 4.4-litre upgrade engine conversion for GT3 models.
With increases of up to 80Nm and 95hp available versus stock-engined Porsche 997 GT3s, Manthey’s 530 engine kit includes a redesigned crankshaft. It’s the most powerful engine upgrade package offered by the Nürburgring 24-hour winners.

“Serious engine construction involves craftsmanship far in advance of simple engine map reprogramming,” explains Olaf Manthey. “It is important for a 24-Hour winner to say that engine design and development is done in-house, with no external knowhow. Using Manthey designed and race proven parts is the only way I can hold my head up high, saying “our team did that.” Those driving with one of our engines in the back of their GT3 know that Manthey power is a very special feeling.”
Manthey offers smaller upgrades, adding up to 35hp to early GT3s. The full range of Manthey products can be seen on the Porsche Racing website.
