5-port. I got a used ebmodded 5port and put in my buggy. I have been trying to tame it down for some time, but will only go so low. If you get the chance get the 5 port the low end is stump pulling.not that the 7 is a slouch either. I am running 2 of them one turbo other non turbo. but the 5 is more bottom end. your above combo should work good.
