It seems  there was an engine developed from the "B" engine through 
another version  ("O" ?). It was the Rover T16 and did go to 2.0L with 
turbo....but would  it drop into an MGB?  Probably a little 
difficult.  It could put  out 200bhp and some went to 800bhp (owwww!)



OK, to add to my original response ("No"), the O series did derive from  
design studies on the old B series, but:
 
"By the autumn of 1972, the O-Series name was formally applied to the  B-OHC, 
and it marked the point in time when the final link with the original  engine 
was removed (..."the deletion of the "camshaft"/jackshaft so that the  whole 
B-Series tappet chest could be pared away"). The B-Series'  design had acted 
as a starting point, but no parts were shared -  and this is demonstrated by 
the cylinder block's light weight (due to the walls  being thinned), meaning 
that the strength of block could be braced in to the  exact tolerance required. 
This weight management would underpin the O-Series'  transformation into the 
M-Series during the 1980s."

The new engine did not even share bore, stroke, nor displacement with the  
old engine. So no parts or dimensions were carried over. It was a new  engine.
