Hey guys, We am considering building a 4x4 offroad racer based on the Daihatsu Feroza Platform. Our team would like to compete in the 4cylinder category. Would anybody know up to how much we can rebore the 1.6L Feroza to increase engine displacement? Could we go upto 2.4L?
Is there any machine shop catering to this kind of service? Is there a resident expert here in tsikot who knows the answer?

Secondly we would also like to install either a turbo charger or a supercharger. Since the stock Feroza is not designed for turbo charging?
How much is the maximum boost that can be considered safe? We would appreciate if you can recommend a shop specializing in turbocharging as well.

Thirdly our target is to increase the HP of the stock Feroza from 86HP to 150HP by doing both rebore and turbo charging. Is this a realistic target or a shot into the moon?

Maraming pong salamat sa mga experts ng tsikot.
