ok I have a b16a2 engine in my civic and it is quick i love it, but i would like to get some more torque and horsepower out of it. now i was reading about the ls vtec and the cr vtec, but i was also reading about stroker kits. now what i would like to know is what exactly does the stroker kit do? does it make the rods shorter with longer stroke on the crank shaft? i don't understand it can someone clear that up for me? also which would be better getting a stroker kit or doing a ls/cr vtec swap?
