ive got a mk4 van 1.8 deisel want to put a blacktop 2 litre zetec in it,just wondered how big a job it is or a puma engine ..........

 

your best bet with this type of conversion is a complete donor car, you may have to mod the engine mounts a bit and probably the exhaust, and do some mods to make the engine loom fit with your current loom, but like everything, given enough thought and planning and it should be easy
