i wanted to know how many miles an h23 prelude engine will last. It already has 152k and pulls really good. How much more do you think it will last? Its been really well taken care of and take good care of i t also. I just recently paid for school so i wont be able to get my swap anytime soon anyways ive looked into getting it rebuilt and i got some decent estimates, most around 1500 cash. The rebuild would be with stock internals and a little higher compression pistons if i want. Im thinking that i might want to boost when im done with school and working and ive heard that the h23 loves the boost. I was also thinking of the h22 swap but ive been told by several people who have had both non vtec and vtec doch's that they all recommend boosting non vtec motors, like the h23. they say that vtecs have too high compression and those are better for all motor. Is this true? What do you guys think? Any help is much appreciated
