94 Toyota HELP Needed!

Hi!

In Nov 03, my engine "blew". IAfter months of searching for an
affordable engine, I finally found one last month (used). I recieved
it, and now things just aren't right...I am hoping someone can help
me!!!
Nothing seems to be lining up. The manifolds are not lining up, and
there is no Emmissions on the new one. The company I bought it from
demands that it is the correct engine. I have a 94 Toyota P/U DLX 4x4.
The engine I bought was from a 91 Toyota P/U 4x4...so everything
"should" fit! My question... I have numbers off both engines(7 digits
long), how do I find out exactly what engines they are, from these
numbers? Maybe my engine is the problem (I could have an engine that
really isn't a 22RE) Any help would be greatly appreciated! I have
been without my truck for too long!!!

Is there an engine numer tracking place? PLEASE HELP!!!

Thanks for your time!
Sincerely,
Julie
