Hi
Ive bought a 2 Ltr zetec to go into my s2 but hAve been offered a mk1 focus Rs duratec engine.
Is it and different to fit than a zetec ?
Mounts the same ?
Engine same size ?
Will my rst gearbox still fit ?
Manifold options compared to zetec ?
Any info appreciated guys

Basically need to l know if it's as straight forward as a zetec conversion is
Thanks
