these sites are good from what i can tell ps think the 1.8 is alot easier than 2.0 cause you won't need to change much. as far as i can see you need mounts due to oil filter you can buy them from retro ford website, need to plug holes in block and skim and either decomp plate or skim pistons, i'd look into that abit more though before making a choice of what to do ie how thicker plate or how much skimed??
