if you started with a D15B1 engine from the 88-91 Civic STD (4-speed) model which was only 70hp and converted from DPFI to MPFI and used the D16A6 camshaft, you might approach 33hp gain, but i doubt it would make it - would essentially be like starting with D15B2 (92hp), converting from DPFI to MPFI and adding D16A6 camshaft - would probably end up at around 98-100hp
