    I bought this cougar in Georgia in Feb 2003. This car specifically was to modify, drag race, and just have a fun rust free car in the summer(difficult to do in Michigan). Its been a fun ride. I have went through a couple of engines, trannies. About year ago I decided I wanted to hit some 11's in the 1/4. I started researching an upgraded head and cam for the 2.3T. Not lots of good, inexpensive options. Plus I need 450rwhp to move my 3450lb fat cat. I just didnt want to deal with a 450hp 2.3T. So I decided on 302 swap with turbo. Well that lasted about 6 months....after I had already purchased an engine for the swap. Because of the weight of my car, I would really load the turbo 302 down. Basically the stock block would fail me at 450hp or slightly more. Not really worth all the expense and work. So the project moved on to the 351w. The 351w swap above the 302 will cost addition $800. But with young children. I almost have more money then time. So I want to do it once.

    Im about 40% through a 351w turbo swap. I already have removed the factory 2.3T and C4. I have received my on3performance fox mustang 351 swap kit. http://www.on3performance.com/mustang351.html Not the best quality, but for $1500 shipped to my door....put me in coach....

    An early christmas gift to myself. I got it last Thursday. It was shipped to my office. ;-)

    I already have a Stingers PiMP I got this summer( http://www.stinger-performance.com/universalparts.html ). It look pretty dang neat.
    It looks like all that I have to modify in the wiring harness is 8 injectors vs 4. I have a couple other 2.3 injector harness. If anybody else has a better plan let me know.

    Couple of things I need to make the car run. Injectors, 3G alternator swap, Chucks motor mounts. I will be using a 351w Spyder intake with EFI elbow. It should just fit. Im not a cowl hood kinda guy. Things I will do after the car is running. Upgrade my 7.5" rear end and suspension. Bigger fuel pump. My Walbro 255 is 9 years old. Subframe connectors so I can continue to shut my doors.

    I'm hoping to have the car up and running by May 1st. We will see.

    Good luck with the swap! Your youtube video is one of the things that convinced me to finally do a 2.3T swap a few years ago.

    Hard to believe that was in August 2007. Back then I was still using the big VAM. It was a one trick cat if you know what im referring too. WOT was great...but nothing else was, It did make good power though. In 2009 i upgraded to the 2.3T MAF conversion....didnt have much luck. 2010 I update to SVOJohn speeddensity code for 2.3T. That was damn good. I also had Quarterhorse, BE software, and a LM1 wideband.

    Spring 2011 my second child was born. So I know I would be busy for the next 6 months. So I decide to do the V8 turbo swap.

    this is a cool project are you going to keep the stock pistons or get some forged pistons to handle the boost?

    Well not quite sure on that. The stock pistons are pretty good for boost. If you know what you are doing and keep the revs down. They seem to last well in to 600rwhp. I wont be looking for that any ways. My fuel system isnt getting the big upgrade this year. Just the big 340 Aeromotive pump. The really big fuel will have to wait until 2013. So my plan was to get a van 351 from a local yard. There are several.

    Then a friend of a friend has a fresh rebuild 95 block 351 with 9.2 hyper pistons, cleanup E7 heads. He ran the engine for 60 mins 2.5 years ago. Then removed it from the ranger he had been playing with. The engine has a performance products spyder style intake and the correct oil pan. Just not sure on the rods and crank.

    Im going to check that out next week or so.

    Thanks,
