Motor Modification Seat 1.4I 2001 (60CV 5V)

Good to everyone, I am Javier.
I just inherited a Seat Cordoba 6K of 2001 with a 1.4i 60 hp and for what I read it seems that it carries 5 valves alone, telling that this same engine marks 100 hp in another version ... My question is, will it be possible to add the remaining valves and the differences of 100cv to turn it into that model? Where could I read of this modification? thank you

Hi Jabier, I don't know what you mean with "5 valves" ... will be 5 speeds ... This 8 -valve and 60 hp engine shares the same block as the 100 hp, but not the same pistons, nor the cylinder head (16 valves) or electronics (switchboard or equ) with which, I do not intend to discourage you, simply tell you that there is no "tunning" that is worth the engine. legal) or buy the 100 hp directly, I already say, add valves to a cylinder head ... You should look for more information and you will see what I tell you. Greetings!!
