HEYYY JOE! ------ Lots of guys on here looking for more power "on the cheap". Many of them end up spending big bucks on some big power parts, build a high horse toy for more than they entended to spend, and they go Fast! Seems to me, if there is a way to get long living / big power on the cheap, these guy ain't telling. Just my opinion.
Truth is, money = power. The more you are willing to spend, the faster you can go. If you do have the money and are willing to spend 5-10 grand or more on an engine, you are at the right forum site. And these guy know their stuff and can help you go Fast.
I am somewhat surprised there isn't more info on this sight for the budget minded guy. I mean, a guy that can spend 10 Thousand bucks or more on an engine Should go fast. Going fast for 1500-2500 bucks takes some ingenuity, and usually ends up being a big blue hand gernade that's fun as he!! Till it blows up.
I would advise you to use the search function near the top, and search search search, get your wallet out and hold on to your a$$ !!!!!!!!!!!
