i got a honda crx and i swap a b16a engine and when im shifting theres a big jerk is it ok?and i want to know does k20a engine matching for crx 1991 model

when you talk about the this hard jerk does that mean that when you shift that you are at red line??? or are you dropping the clutch? i really cant understand what it is doing. to answer the other question yes they do make swap kits to put in a k20a and from the research that i have done it is a really good swap and it will make your car really fast but that is just on theroy dont acually have one
