I cannot find anyone to rebuild an engine in a 94 Nissan Sentra SER. The bad part about it is the engine has 79k miles on it. One cylinder has 40% compression. It has been sitting in my brothers garage for the last three years. I was going to buy it for my son. I have been online for the last few days looking at rebuilt and used engines. Its tempting to pick up one of the engines from Japan but I am not sure I want to go that route. I have found rebuilds from 1400 to 2200. Any of you ever buy an engine online?

There was kid i sorta new in HS who swapped out his 240sx engine with a more powerful one. I think SR20 to SR20DET (2.0 litre to 2.0 with turbo or something not entirely sure). He got the engine from japan, was used, probably 20-30k miles on it. I don't think he's had any troubles with it. I have lost contact with him but there are many people who do the same thing and have no troubles buying an engine from japan and getting it shipped.

I bought a crate engine from FordRacing.com was shipped, have had no problems with it. But it traveled far less distance than one you'd be getting.

ordering crate engines from Japan is the best route, you can get an awesome used motor with a warranty shipped all the way here for the price of rebulding that engine.

(edit: that bad cylinder is most likely just a stuck valve and can be fixed fairly cheap, escpecially with only 79K on the car. A quick ELD test would let you know where your losing compression.)
