VASIMR plasma drive in GURPS...

300 km/s exhaust, if I'm doing my math right, won't even get you up to 10 mps per tank. So you need lots of reaction mass, though it might be substantially better than the Spaceships stats for the ion drive.

Achieving high thrust is going to demand you take the power level up a lot. At the 1.5 kg/kw, assuming that's power of the exhaust jet, it looks like it would take a single engine system almost 8 days to go through a tank of fuel. At the 30km/s exhaust. High impulse mode is much worse.
