Re: Civic HX engine rebuild for MPG and Durability
Whether you're doing stock or upgraded setups:
1. make sure everythings clean enough to eat out of when you put it back together.
2. quadruple check every measurement.
3. torque everything exactly.
3a. chase all the threads with a tap or die. make sure they don't have oil, anti-sieze, lock-tite, or anything else on them unless the factory manual says so. torque=frction x tension. friction down = tension up at the same torque and thta's how you strip threads and break bolts.
3b. Don't go an extra 5 ftlb to be sure, a friend of mine tore up his rod bearings because he put an extra couple ftlb on the rod bolts. it was just enough they didn't stretch right and ate 2 with visible wear on the other 4 after 400 miles.
as for upgrading stuff: the easiest thing to do for no extra charge is when you get the head and/or block milled to get a nice straight surface for the head gasket, have them take off a little extra to bump the compression. compression=power+mpg.
