Do the 1st gen SiR b16a and the 2nd gen SiR b16a cranks have the same specs? Are they interchangeable?
Thanks

 

Yes, in fact all b-series cranks are interchangable in the block. I know its awesome isn't it.

I think you need to study a Little bit more at Honda University

ALl B16A crank are interchangeable

B16B is unique

b18a/b-b20b/z are interchangeable

yes but you can put a b18a/b crank in a b18c block but not a b16a

Well yeah i see what you mean, i just meant the bore spacing, journal width and diameters are all the same so the crank itself will work, but yes of course stuffing a 89mm b20/LS crank in a b16a would require some short rods or some radical compression height pistons.
