BPU N/A you can go with a walbro but I think it is an over kill. Back in the day when I had my N/A with Intake, headers w/ full exhaust, Ignition, ported tb, ported manifolds, and 5th & 6th port inserts I did run 550cc secondaries with a stock pump and the car ran very nice. I dont think you need an upgraded pump but you might want to go to a little larger secondaries. You will also need a way to do some adjusts i used an Apexi AFC and a wide band.



I had a very stout running N/A. Till i turbo-ed and blew it
