Jenson Button and Fernando Alonso could get an engine boost for McLaren's home British Grand Prix, with Honda now considering an upgrade as early as this weekend.
In the wake of the growing pace of the McLaren-Honda package, in Austria the team produced its most competitive showing since it renewed its partnership as Button raced near the front early on before finishing sixth.
Honda has been open that it has plenty of design ideas to bring on board this season, but it was holding fire on introducing them while it worked out how best tactically to spend its remaining engine development tokens.
But when asked by Motorsport.com about the impact the Austria performance would now have on its plans, Honda F1 chief Yusuke Hasegawa said: "I don't want to wait.
"So as soon as they are ready we will introduce them, even in Silverstone. But I haven't got the information yet so I need to check that we can do that.
"It could be next weekend! But actually every race I am expecting to introduce a new update."
Honda spent two of its engine development tokens on a new turbine at the Canadian Grand Prix, but its focus will be on improving its internal combustion engine.
It believes its energy recovery performance is good enough for now, which is why it must concentrate on bring out-and-out horsepower improvements.
"Yes, it will be the engine," he said
Hasegawa also pointed out that improvements were also necessary because Honda had had to make some compromises with the Montreal turbo changes.
"To create enough power, we spent a little of the engine power for the exhaust, and we sacrifice some engine power with the new turbine," he said.
"I think since we have introduced the new turbine [things have improved]. Canada and Azerbaijan are too competitive from a power point of view.
"We've come back to a normal circuit and I think that is the reason why we can prove that our update was working well, I think."
