Kris1212... you need to give a better response than two words. The B18B handles boost better when left stock compared to a h22. The h22 also costs much more and is a little bit harder to swap in. But if you have the money to get a h22 and build it up, then it should handle a good amount of boost. Some people swear by the B18B and others always go for the h22. I think it’s up to your budget.
