i was wondering can a ls acura crank go into a b16a civic and would it be more of a stroke and what all what would i have to do to replace the crank

 

No.

Unless of course you get custom length rods, which would cost more then your entire engine.

 

why would you put an LS crank into a B16 anyway? The ONLY thing that makes a B16 put out any power is it's high redline. Put in a crank with a longer stroke and you'll drop that redline. It's already called the Torqueless Wonder for good reason. It would be the Gutless Wonder with a longer stroke.

 

he is looking for more displacement via longer stroke, if you want a 1.8 liter motor just buy a used GSR bottom or build properly an lsvtec.

the deck height of the b16 and b18's are different.

 

9mm, to be exact.
