I would say that such a drive would be limited to J4, because of how
it's made - each extra parsec of range requires not merely a bigger
drive and more fuel, but a drive of higher TL.

*However*, a drive intended to allow J5 at 300 DTons (and thus designed
and manufactured at TL14), but made a little over-size (20 DTons rather
than the required 18 DTons) would allow J4 if mounted in a 400 DTon hull.
