even if you do them right , upgrade the pistons/rods/rob bolts they tend to be unreliable , like its hard to get 20k out of one built right. Most of the time its due to oil starvation , the b18b does not have oil squirters like vtec blocks. ever once in a while someone builds one right that will last 100k+ miles , but its rare.
