I cant decide wether i want to go with a B16 or a b18c in my 1991 integra. For the price of a B18c do you think i could upgrade the B16 and have better results "Faster" than just putting a b18c in. And another question, if you had the same everything "driver, car,etc" except one car had the b16 and one had the B18a, which one would win a race?
