2 ways....
1- get a few mates and get some strong ropes or lifting straps - thread the ropes under the engine and out the pther side (over the wings) - now every one lift - its very akward this way......but do'able
2 - remove everything from under the car then unbolt the engine....then jack the car up to fu.ck so that it clears the engine then slide the engine out from under the car on a skate or a trolley jack
other than that, your out of luck.
