I know they work well for the guys with blown cobras that up the stock output. If it can be used for a focus ( and it should be ) it may supply enough fuel for a direct port hit. If you run a fuel safety switch ( I recomend it ) you will know if the stock pump falls short. The SVT pump is great, not sure if it works on the dura.
Speed is only a matter of money; how fast do you want to go?
