The LS r/s ratio isn't really something to worry about. The LS r/s ratio is 1.54:1, and the GSR/ITR is only 1.58:1, not a very big difference. Ideal R/S ratio is 1.75:1, the b16a has a 1.74:1 r/s ratio, almost perfect. You can make your r/s ratio better by destroking the motor, but at the cost of lost displacement.
