Charlie said it well, focus on tune and fuel and you should be fine.


Seriously though, I've beaten the **** out of this stock long block for 2.5 years now and it's still going strong. I can't even fathom how much nitrous I've put through it. I have a refill station here at the house and I usually have to top the bottle off every other day or so in the summer. With a good tune you should do ok with the stock bottom end. Most of the time I run a 150rwhp shot and have played around with a 200rwhp shot on the street. At this point I'm really thinking of spraying a 2 stage 250 shot (at the crank) next year.
