Nice comparison, my basically stock D15b2 in my sedan came out of my 91 hatch. Hatch was wrecked... Dumbasses. Anyways, Exedy clutch and Lightened flywheel and i was walkin on a buddy'd 1.6 vtec ek hatck. Rotating mass has alot to do with it. I strongly love my sohc d15. Its such a strong motor, and i never second quess it. Im about to go MPFI y8 head vtec on it and gonna scoot a bit faster
