Hi new here

Hi,have got a skoda octavia vrs(02plate).Engine nackered apparently some drift wheel at the bottom of belts has sheared.Been told i now need new engine as less cost and hassle.Old engine has AUQ code.Have heard about a seat leon cupra 225bhp and wondered if this would fit straight in on existing gearbox and engine mounts?Would be gratefull for any other sugestions.Need to try and locate engine asap and have it fitted for sunday 7th feb at latest.
