Depends on how much you wanna spend really.
Get in touch with Pumabuild for something pushing over 200BHP.
But all that power is not really needed in such a small car, and the Puma 1.7 is very tunable (around the 200BHP mark), and that will be enough power to drive about in every day.
I'll be getting a 1.7 Puma lump in mine at the start of the year.
