FG SERIES I & II
PRICE GUIDE: $13,000-$29,000
FOR the FG model, Ford finally went to the turbocharger unit that the XR6T should have had from the start. While the original used a large snail for lots of flow, that inevitably led to some lag. Not terrible, but not as snappy as some of the emerging small-capacity turbos that were starting to rule the world. But by fitting a smaller turbo unit to the FG, the lag was suddenly banished, since the turbo could spool up much faster. Outright power was now up to 270kw and torque was a monster 533Nm. The difference is obvious from the first drive, too.
The trade reckons the FG is the one, but you’ll need to swap the stock turbo pipe for an aftermarket one, as core shift in the casting process makes the standard pipe notoriously thin-walled in places. The fusion-welded tailshaft of the FG is also a worry and they have been known to twist. An old-school welded shaft from a BF is the replacement.
