The puma engine will bolt to your gearbox, you just have to make an engine mount for the timing belt side, Id prefer to modify the rocam, having a sportka myself the engine has bags of potential, a one litre version was available in mexico with a supercharger put out over 90 brake. If you wanted 1.8 or 2.0 zetec you need pre 03 1.3ka gearbox and modify the slam panel a little
