Just sold my 94 v6 5.0 swap project. Picked up a high mile 04 with bad engine. I can pick up a 07 Crown engine for cheap. Low miles. Is this a bolt in swap? I figured in using the Mustang manifolds. Will everything else work?
Yes! Aside from a few nick knack nickel and dime crap, should bolt in fine. Swap all your covers onto the vic engine.
The 07 Vic engine is actually better then what was in the 04. Should have the better 8 thread heads on it.
Its a bit more involved. Besides all the engine necessity such as harness, computer, fuel supply, the Kmember and tranny will need to be swapped out as well.
Oh, wait. Did you mean modular windsor/remeo diffrences? If so, yea...no big deal. Both engines are uniform except petty stuff like valve covers, bolt sizes.....nothing you wont be able to figure out.
The injectors are different, a knock sensor (which you cant use), and cylinder head temp sensors that you just leave in and dont hook up. Swap over your stock injectors or else youll run rich.
Nothing from the 3.8l to a modular is going to interchange. 3.8l is more related to the old pushrod family.
Im a little confused, are you swapping a 4.6 into a 3.8 car or did you buy an 04 gt with a bad motor and 07 crown vic to swap the motor into the 04 gt?
Oh dang....its me thats confused. Go figure. I re-read the thread. He picked up an 04 gt with bad engine. The vic engine will swap into the 04 with minimal problems. All accessories will bolt onto the 07 vic 4.6l. If there are major differences, itll be cam covers and front cover. Dont sweat it. Youll figure it out
Yea I was confused too lol. To add onto what I said youll have to use the fuel rails, upper intake plenum, exhaust manifolds and throttle body from the mustang. Theyre all different from the mustang and another little tid bit, the 05+ vics use drive by wire. The cam covers should be the same as the pi mustang covers.
If your going from a windsor to a romeo or vise versa the only main differences is the valve covers will be different and that you will go from a 6 bolt flywheel to a 8 or vice versa if its a manual. Should be an easy swap. Just use the intake and fuel supply components from the mustang and your good to go.
Swap valve covers, Injector/fuel rail, Timing cover, oil pan, Oil filter adapter, throttle body, flex plate (if you are going with an auto) and water pump. Keep the Intake manifold. I did this on my '96 and this is what I needed to do. The new engine should be Romeo, if im not mistaken. I know my '07 crown vic engine was. The '04 should be Romeo also.
ended up using a said to be 2001 town car engine. swapped exhaust, found out the hard way that although the flywheels are same diameter and number of bolts the diameter of he holes for the converter were off. so flywheel had to be swapped in car. also found broken trans mount that no one stocks. had to order on line to get one less than 60 bucks. engine is in and bolted up but plenty to do. waiting for son to come back for another weekend to finish up.
