Engine tuning in Portugal is crime for two reasons: Legally speaking and the price of certain things, like fuel.
If I buy a car today, 4 years from now, I have to go to a thing that we call IPO. In the IPO the cars have suspension tests, breaks tests, emission tests, verify the correct dimension of the tyres, etc
The test results depend on the car condition. If the car fails certain tests, the car has to go to the workshop, end return to IPO to see if the problems have been repaired. Two years later the same thing, another two years the same, an than every years the car has to go to IPO.
Now days for example if the police think that you have modified the car, they send you to an IPO B. In an IPO B, the car suffers more tests to see if he has more power, if the engine is the same when the car was booted, etc
Id putted the list to know if it was possible to do that sort of things (I know! Impossible is nothing), if it was possible to put a two litter engine in a small body of a Saxo.
Now about carbs
I like cars with carbs, because the have more torque at low RPM than an ordinary injection engine and in a carb engine, if you want it to have a little more power (a little hover boost

) we just have to rise a little bit of the throttle pedal, and than put the foot down again.
(please if I write a mistake, tell me!!!)
