Re: S3 Au falcon xr8 220KW engine in EF XR8
Yeah mate, go with the dizzy otherwise you're up for the whole swap. The fuel pump sounds perfect as long as your return line can cope. Fit a fuel pressure guage to the schrader valve and check at idle. Once it's running get a full throttle dyno tune to verify your mixture is OK as you're now running an engine with different pumping characteristics and injector size to what the EF computer thinks you've got.
If you end up not using the AU PS pump let me know. I may be interested as mine got burnt out.
