Default difference in injectors?

From Non-H.O. to an H.O. injector swap. Is their a night and day difference? Who has done it?

I think there would be no difference at all between HO and non HO injectors. There is a night and day difference when swapping injectors from a neon into either HO or non HO.

See the thread below and search the forum for several threads about injector swapping.

Hope that helps

There is a difference between injectors from an Ho to non Ho cause the only thing that makes an Ho and Ho is the intake has bigger ports there for the engine needs more fuel to even out the air fuel ratio....
