MG with Nissan B-210 motor

[Joe7670@aol.com]

I am looking into buying an MGB.  I found one with a Nissan B-210 motor in it.  
Does anyone know what the good(or bad) word is regarding this conversion?
Do those motors bolt right onto the original transmission, or would the 
transmission also be nissan?

Any info. is greatly appreciated.

Thanks,

Joe
