The 25-year-old Ulsterman was pressed to the limit by Italy's Max Biaggi. Just half a second split them as they flashed over the finishing line.
He was fourth in the opening race while Eugene Laverty struggled with a 15th place, followed by a retirement.
In the second race Rea was involved in a last corner crash after making contact with Leon Haslam.
However the Ballyclare man managed to stay upright to win ahead of Max Biaggi and Tom Sykes.
"It's nice to win and, in that second race, everybody wanted to win so bad," said Rea.
"It was a crazy race and I made it hard work because I dropped off the group again in the middle stage and then, when I caught the group, I made a big mistake and ran wide at the last corner.
"I was quite happy with the fourth in race one as well - the guys gave me a great bike and Chris [Pike - crew chief] and his team were on it all weekend. It's nice to come here and get a good result because it's never happened in the past with Superbike," he added.
Eugene Laverty was 15th in race one and crashed in race two.
In the opening race Rea on a Honda was fourth after qualifying fifth.
Rea now moves up to third place in the Championship standings, 20.5 points adrift of leader Biaggi, putting him back in contention for the World title. After five rounds Rea has jumped two places to third. He has now won two races this season.
