ByKolles Racing will switch to Nissan power for the 2017 World Endurance Championship, utilising the same engine that NISMO developed for its short-lived LMP1 hybrid.
The privately-run German outfit has agreed a deal with Nissan to supply the 3.0 litre, V6 power plant for its CLM P1/01 prototype.
ByKolles previously ran with a 2.4 litre, V6 engine manufactured by British company AER.
Team manager Boris Bermes said that the new package would bring improved reliability to the CLM in 2017.
"Engine supply from NISMO is of huge significance to our team," he said.
"After having to deal with many setbacks in the past due to engine reliability issues, for the 2017 season we are expecting a significant improvement in terms of both reliability as well as performance."
ByKolles Racing finished second in the three-car LMP1 privateer class last season, with the CLM's best result being sixth place overall at the 6 Hours of Spa-Francorchamps.
Bermes confirmed that the twin-turbo NISMO engine – originally developed for the front-wheel drive Nissan GT-R LM NISMO – will deliver its power to the rear axle, through a gearbox system supplied by Xtrac.
The naturally aspirated CLM P1/01 will also feature a heavily revised aerodynamic package in a bid to pull the car closer to the hybrid LMP1 field.
"We are relentlessly working on numerous additional improvements to our car," said Bermes.
"As a result of the changes in regulations for 2017, we will be able to make big improvements to both the front and the rear, particularly in aerodynamics."
"In addition to that, our design engineers have achieved a reduction in weight and have introduced comprehensive updates to mechanical components."
ByKolles Racing intends to open up the CLM P1/01 chassis to customer teams in 2018, although orders won't necessarily be tied to the Nissan engine.
The decision to sell the car to customers comes after BR Engineering and Ginetta announced respective LMP1 privateer programmes for the 2018 WEC season.
