I own a 1990 Prelude SI with a ""good running"" B21A1 in it and the car has a lot of sentimental value so i can't give the car up. I'm torn between whether or not to rebuild the B21A1 which ive heard is a very dumpy engine or to swap an H22 into it which ive heard is very hard swap in my model of Prelude. :uhoh: Any suggestions on what to do would be extremely helpful
