Have totally done all the cosmetics to truck, now time for engine. The truck as had a fuel injected engine installed. engine runs great. I know it is not a race car but would like a little more power. I am running 33's with a 4banger so was thinking of going 31's and try to find lighter wheels. Have been trying to find engine parts and cant seem to find any sites with much for my truck. Any info would be great. Is there much I can do besides header and maybe air cleaner. Cant do much to internal engine live in Calif. and this place sucks, seems to be picky. New to 4x4 am used to mustangs and the typical bolt on parts. This looks to be more technical but am up for challenge. Will try to post pics of before and after and updates. Thanks for any help!
