Whats up homies. just wanted to get a little info. I have a bare gsr block at home and a b16a sir1 in my hatch. i believe this motor cranks out 160hp and 111tq and has a ratio of 10.2. well wat i want to do is pull the pistons out of the b16 and put it in the gsr and slap the the b16 head on it and create the so called poor man type r. i know it more detailed swap than that..also wat is the difference in the two motors. sir2 cranks out 10 more horses, 2 more lbs of tq and .2 more compression sooo did honda achieve this with different pistons, diff ecu, intake mani or wat.
