more horse power from 2 litre motor

what upgrades has any one done to get more horse power from there 2l motor my truck is to way slow

Well there are headers, a weber carb upgrade, some people use the KIA motors, as well you can use the fuel injection and turbo setup from an MX-6....there are cams out there for them, and I guess you could get an aluminum dirveshaft made up too...
