Sup, guys and girls I am completely new to Nissan motors and just happen to have bought my sister in law a 01 Nissan Sentra SE for $1500. The only catch is the engine overheated on the person who had it before and may either have a blown headgasket,cracked head, and possibly damaged piston rings. My initial idea was to just go buy an engine for it and throw the old one away keeping only the sensors and stuff that can be used later. As of this weekend I have gone crazy looking for a motor to no avail but I have been asking for a 00-01 engine.I did a compression test in hopes to maybe just changing head gasket will get the car going,cylinder #4 had 60psi, #3 had 0psi and thats pretty much were I said forget about even changing the head gasket. I also found one spark plug with water on it when I took it out (the one in cylinder #3).

Will an older sr20de(I believe is the engine I need) work ?
Anyone know some where in florida where they have these motors?
How much should I expect to pay? so far I've gotten prices from 500-800
Do you guys think I should still try changing the head gasket even though I got one cylinder marking 0 psi (obviously I will be taking the head to a machine shop to be straightened out)?

I have one last place that said they have the motor for 550 I may be buying it and installing this weekend coming up.
