Let me educate the uncivilzed...

Because of the shortened deck height of the B16a motor you will have a not so pleasant rod/stroke ratio...taking that you are still planning to use the stock 1.6 rods. Just get a b18 block those things are almost for free these days. You can build one decent block for less than $1200.00 as long as the block is in good condition and just need to be honed cleaned and all that happy stuff.
