It is in Turkish but if we summarize the deal has done with Ukranians about tank engine .8 Ukranian engineers selected from UkrOboronProm and 3 or 4 Turkish enginners will be include to this group . They will begin to develop a new engine for Altay tank.They say they offer this engine to allies of Turkey and he gives Pakistan as an example.
They also offer 200 5TDMI1 engine which got changes to work with Fırtına's transmission for export version.He says there will be no restrict for this engine.
Also they offer 100 6TD engine for Altay's export version but I dont think its suitable for Altay with limited torque.
