Ok right now I have a 1990 crx si with a zc motor. And I have the option to trade with someone and give them a few hundred for a 90 integra with a b18a1 with a gsr head and first off what's the power of both and then what would it be with a gsr head? The b18 has less than 500 miles on it and he has some headers and says its pushin about 220hp is this correct? Is it more? Or what the only problem is he says one of the head bolts stripped and is trying to say its gonna cost like 200 for him to fix. Will it run fine afterwards or should I just rethread it myself? Please let me know asap!
