Does any one know if the Mass Airflow Meter on an Aust 5.4l can be used on a US 4.6l???

I am not 100% sure what size MAF the BA 5.4L runs, I am guessing 90mm. I know the 2003 supercharged 4.6L runs a 90mm both should be Bosch units. The naturally aspirated 99/01 4.6L DOHC engines run a 76mm unit. Only last week I bought a New 90mm MAF and injectors off a 2003 Supercharged 4.6L off Ebay in the States for less than what a 90mm MAF goes for here. There seems to be plenty available over there. I'd stick with what the engine came with. It is easier to troubleshoot if the engine won't start.

I am not sure if you received my request before the server crashed, in case you didn't, would you be able to measure your supercharger crankshaft pulley and the supercharger pully. I need to know the standard ratio between the two. Thanks
