Toro Rosso's Franz Tost says he'll wait to see how the Honda engine performs in testing before he worries about engine penalties in 2018.
Formula 1's power unit restrictions will tighten even further next year, with drivers allowed just three engines for the entire season.
Honda's agonizing struggles with reliability during its partnership with McLaren will likely fuel anxiety in the Toro Rosso camp, but team boss Franz Tost says there is no sense in building up the worries for now.
"First of all we must see next year's engine tested, and then we can think about possible penalties," he told Motorsport.com. "But it's far too early now.
"The reason we requested to work together with Honda is that we are convinced that the company has a lot of potential, it's a worldwide known car manufacturer with a fantastic motorsport history.
"And we at Toro Rosso are proud to work together with such an exclusive partner.
"Now it's time to come up with activities and hopefully bring the complete operation from Toro Rosso's side as well as Honda's side to success."
Tost admits the Faenza-based outfit will benefit from augmented R&D resources thanks to its Honda deal. But the Austrian manager insists the team will proceed with caution.
"A budget is one story, building up an infrastructure is another story," he says.
"All this takes time, and of course if we need to do something urgently on the R&D side we will push for this within our resources.
"However, we are bringing in some new people, because we have to do it.
We had a completely different plan for 2018, we wanted to use the complete rear end from Red Bull Racing, or Red Bull Technology, which is not the case anymore because we have a different engine, and we have to bring in people to bring this project to a successful end. But this is a normal process."
