The actual PR required is 53.0. Which means every upgrade apart from the last Engine and last Body. Altogether, probably around 140 GC to get there, but the Gold rewards from Project Impulse, getting it for free instead of 260 and series it unlocks mean it's not that much of a spend all things considered
