I just bought a 2000 Ford Focus SE, and I was wondering what all modifications I could do to gain a little bit more performance?
It's running the 2.0 16v DOHC engine, which I know is normally a decently powerful engine, but it seems to have less power then my old 94 Nissan Sentra that had a 1.6 DOCH in it.
I was told by a friend who is a Ford Tech at a garage that the computers in Focus's are designed for less power because it gives better fuel economy. But I would rather have a bit more power and sacrifice some fuel mileage. So far, I've only given it a tune-up, New plugs (Bosch Plat 4's Supposedly the guy at the autostore said they will give a little bit more combustion which will raise performance ever so slightly. If anyone knows better plugs lemme know.) New wires, (Don't remember the name, but they were 8.5mm.), new fuel filter, and new oil and oil filter.
I haven't messed with the intake yet, because I know sometimes getting a better intake would increase performance. But I'm not sure what to look for, so any suggestions would be appreciated.
I was told about getting a "Cat-Back" exhaust and a header for it. I did some looking around and saw some catback systems for like $600… Which is a little bit more then I was expecting, but I might go that route if I get some performance out of it.
Other then that, I don't really know what else I could do. I was reading about chips that change the computer in it and boost performance but I couldn't find anything for under a grand which I was hoping I wouldn't have to pay that much. Lol.
In short if you don't want to read anything,
Suggestions on Air Intake/Filter,
Exhaust?
Is there better plugs then Bosch Plat 4s?
Any other minor things I can do for performance boost?
Possibly a "computer chip" thing?
If anyone has any suggestions, or links to sites that offer the parts you are suggesting, it would be greatly appreciated.
