Apr.1 (GMM) Ferrari will probably not fit a new engine to Felipe Massa's car for the Bahrain grand prix this weekend.



The Brazilian driver spun into retirement at Sepang just over a week ago, allowing him to use a fresh V8 at the next race without incurring a penalty.



But "at the moment, we will probably run Massa with the same engine he used in Malaysia, even though we could change it," technical director Aldo Costa revealed.



Costa did not go into more detail, but using the Malaysia-spec engine could be advantageous for two reasons.



Costa did say the Maranello based team still has "a close eye" on engine reliability, following the two race failures in Australia. Massa's Sepang-spec unit proved reliable both in Saturday practice, qualifying, and in the race until he spun, so it is basically a known quantity to the team.



Secondly, using the Malaysia unit as scheduled in Bahrain would clear the way for a fully tweaked engine specification to be debuted in Massa's car in Barcelona, where all teams are planning significant updates for their 2008 packages.



Test driver Marc Gene conducted a straight line test with the F2008 at Vairano last week.
