Hey guys (and girls), I was a long time member a while ago until I sold my xr T just before I got married in 2012 but since have been building a TD Cortina of which until recently was planning on putting a little Windsor into. I have now decided to put in a turbo donk, but had a few questions regarding the 4litre block, I am intending on using an FG motor so I wanted to know (as I don't have the funds to buy the turbo motor at the moment due to other build components etc), if the all the blocks mounting positions are the same? Does it have a different sump? just anything that may differ from a standard/non turbo etc im sure you get the idea, ill be looking at buying/loaning a dud block primarily for mounting purposes and also the bits and pieces to mock up how the turbo motor would be when installed. Any help would be greatly appreciated. Leo
