I have a blown Head Gasket on my 1989 SR-5. I noticed that it is cheaper to get a low mile replacement out of Japan, then to rebuild. Only hitch is the replacements are only 1.5L instead of 1.6L. Is there much of a performace loss that is worth rebuilding or not. I have 130,000 on current motor.

u can always rebuild the jdm motor and bore it out but dont no how much that cost getting mine done for nothing
