Ok im trying to figure out if i take a bare B16 block, can I put a GSR crank in it? and if i did would i also have to us the GSR rods??? I plan on useing P73 or P30 OB pistons. would this set up be possiable im sure somone has tried it b 4 just nothing specific came up on the search.

 

this was just covered in the last week so.

You cannot use a b18c (Gsr) crank in a b16a motor because the b16a block is physically shorter than the b18c block. You can use a Gsr crank in a b16B block as it's the same as a b18c block. However you'd just end up with a b18c GSR block anyway. A B16b is just a de-stroked b18c. A b16a is an entirely different motor and block all together. The only crank you could swap into the b16a block is a 92-93 B17 GSR crank (1.7L) which would give you a little more stroke, you'd have to use the b17 rods as well.

 

does the b17 have a larger bore than the b16a? or is all the displacement made by the crank?

 

same bore, just slightly longer stroke.
