Haha yeah I know what you mean about the over taking. Just recently converted my 2.8 wagon to a 4.2 and man it's awesome love the power, still have to work something out for an air box and then get it tuned and it should be a blitz to over take.
We ran an eBay front mount intercooler and 3" ally piping, if you have the room for a front mount it's a good option if you don't do a laminova.
