I was wondering if any of you know what the diameter of the j's racing intake (or the replicas) is because I know that for an all motor build 3" is a must. Another question is are all aem intakes 3"? What aem intake would I buy if I have a b20vtec in a 1996 ls, would I buy one for an ls since it has an ls/type-r mannifold?

This is just an educated guess, but I'd say get an intake for the Type R, since that's the closest 'stock' car to the engine you have in there now.
