OAK will use HPD power to return to the World Endurance Championship's LMP1 class for the final two rounds of the 2012 season at Fuji and Shanghai.
Jacques Nicolet's team started the season with a Judd-engined OAK Pescarolo LMP1 car, before focusing on its LMP2 Morgan-Nissans.
As well as revealing its return to LMP1 for the end of the 2012 campaign, OAK also announced at Silverstone on Friday that it would construct an LMP1 car for the next generation rules package in 2014.
"We are very keen to continue in the premier prototype class, which is why we intend to build an all-new LMP1 car in 2014 in accordance with the fresh regulations and in partnership with a constructor," said Nicolet. "I can therefore confirm that our design office is now working on the conception of our 2014 LMP1.
"In order to race at the top level of LMP1, we have looked for the best way to be competitive during this period of transition until 2014. So I am delighted to announce this agreement with HPD that commences at this year's final two WEC rounds."
Nicolet hopes that this year's Honda partnership can be extended into future seasons.
"2012 will be the first step of a collaboration we would like to initiate between OAK and HPD," he said. "We will do our best to confirm the option we have to run either one or two cars in 2013."
