The engine in my beloved 90 accord finally went (almost 300,000 miles), and instead of buying a new car, I've decided just to swap it. I was just going to put another stock engine in it, but my boyfriend suggested doing an h22 swap... I don't really know a lot about stuff like that.. like, about how much more would an h22 cost compared to stock.. how would it handle on gas (i got about 29 mpg) ... any info would be appreciated
