LSs are slow from factory, but u can modify it to make it b what u want. Both 24V 3.0 V6 and 32V 3.9 V8 have a lot of potential.
About nobody selling upgrades. U dont need them to, unless u like to do things easy, u can get a civic anywhere for cheap and have billions of already made parts.
Sad is your V8 slower than my brother 2.4 sorry a$$ neon. Ur srt-8s get beaten every hangout night by small engine powered cars. Thats sad, me? I drive a car nobody has seen around here, rare, in fact I went into the Ford dealer yesterday and the very owner came out to see a stick shift lincoln after arguing for like 20 minutes no lincoln came with manual transmission, unlike urs that Ive seen them in all colors, with all type of ugly nonsense huge rims, boat kinda sounding exhausts. Whats more, Ima take pictures next time I go, and even post videos to show u how "sad" ur srt-8 is.
About all engines r the same, I meant u can modify any engine and make it a rocket.
