Re: S3 Au falcon xr8 220KW engine in EF XR8

Get the AU3 MAF as well so it matches the 24lb injectors. Fuel pump upgrade also worthwhile considering as the EF motor is only 165kW. You may be able to use the old EF pump, but new bigger pumps are cheap and burnt pistons aren't... I'm not sure if the EF runs EGR (EB-ED do, AU doesn't). If it does you will need to get a spacer to suit the 70mm TB on the AU motor. Once it's running I'd get a good dyno tune to make sure fuel pressure gives correct A/F at wide open throttle. If it doesn't then an adjustable regulator is also needed. The good news is that none of these parts are expensive.

I also have a 220kW Tickford in my workshop waiting for the right car. Bought it from a burnt wreck for $750. Check under the rocker covers, there are some nice shaft mount roller rockers unique to the 220kW engines.

Good luck
