Hi, I'm not used to be posting in forums so if I do something wrong, I'm sorry and I'm open to any advise.

I have a 1994 1.3 Skoda Favorit 135 781 with Pierburg carb and catalytic converter. I would like to know what modifications I would need to do to boost my engine's power (increase the engine's HP). The only modification I have done to my car is that I got someone to put an AC to it and obviously we had to change the alternator to a bigger one. I've read some things that some people have done in other forums but I will be doing these changes myself (hopefully) so I would like to have the opinion of the experts

usually an AC system needs a bigger radiator too.

I have a 135 Felicia and they have 2 radiator types: big for AC and regular for a sauna interior

as for a power boost, what expectations do you have from a 1.3 l engine and what budget is available?

hi there my 1.6 with air con uses the 1.9 diesel rad and fan i would put a 1.3 mpi lump in it or 1.6mpi

I've read some things that some people have done in other forums.

so tell us about some things...
