Well broh, Alto goes to about 150 on the stock engine and I don't really race that much. I just want it to look nice. Besides, don't you think modifying the Engine and Exterior is two different things, I mean how are the connected with each other? Like a few other people too asked me if I have modified the engine or not..
To be honest, I don't really know what can be modified in its engine at the first place. There isn't much space under the bonnet to fit anything else.
