so im an idiot convinced my brother to buy this car thinking hey worst case scenario it needs a head right? well he bought the car non running and half torn down so we get the old head off. Warped beond repair so we order up a used head at the cost of 200 bucks and another 400.00 in parts put into the top end of engine Gaskets,belts,hoses,missing bolts,water pump well get it all back together finaly go to start it nooooooo compression lower end shot

so im looking for 1 of 2 things a complete engine or maybe a engine that has bad head but good lower end

my brother is married to this car now so any reasonable help would be more than apreciated
the car is a 96 eclipse 5 speed
