I need to beef up my 95 V6 engine what can i do to do that?

Its all stock right now?

 

Try the link, that is where you will find most, if you dont like that, since you already asked about bolt on's i am assuming you are going for real engine mods now. get ported heads, intakes, and a cam for the most bang for the buck. or a quick fix is always nitrous, safe shot for that is 75 dry, or 75 with and 100 accasionally wet.
