Are there any diferences in the block and head(not talking about moving parts) of the DET and the n/a out of the sentra? I look at the Jspec engines and wonder because I will be rebuilding it with new parts anyhow, and if I can steal one out of a sentra why pay the price an shipping for a Jspec? Your help is appreciated.

 

another thought. It would still save alot of work to buy a front clip and have everything I need(clips,bolts,etc.) I would still like to have all winter to build the engine without having the front clip in the garage.
