i found this link on HMO for there d15b longblock. http://www.hmotorsonline.com/shop/sc2000se...page&item=30019 since i have a d16 in my 95 civic already, could i swap the transmission(5 speed), axels, ecu, fit on stock motor mounts, wiring harness, and other things and have it work perfectly. if not what would i need that i cant get from my D16? also, would i be able to swap out the d15b head with my d16 and get any performance increase. also, i plan on boosting a d series. does the d15b have a stronger bottom end than the d16?? thanks, -MIKE BTW: my d16 has over 180,000 thats why i am considering swapping it then boosting. Is the D15B OBD1 anyway??
