Jerome d'Ambrosio will not enjoy Virgin's full car upgrade in Turkey this weekend.
After a very disappointing start to the team's second championship campaign, team boss John Booth said the improvements for Istanbul are "significant".
"It represents a new direction for us and we're hopeful that it will help us start to turn the corner," he said.
Virgin has been working on the Turkey upgrade since before the 2011 season even began, but only the car raced by Timo Glock will feature all of the new parts.
"Jerome will not have the benefit of the full upgrade package until Spain but he will get a taste of some of the elements this weekend," said Booth.
