Could use like 100 to 150 more hp. Thinking about throwing in a aluminum 4v with long tubes, possibly ported heads, and calling it a day. My budget for a motor and extras is approximatly 5k that is why i quickly thought of the 4v. Anybody have any suggestions. My stock motor runs fine but its not worth it to do a headswap when I can get an 04 junkyard 2v for $1600-2000 complete with low miles. In fact I dont know why anyone does headswaps when a newer low milage motor is only a few $$$ bucks more. Enough of my ranting already. Any suggestions.
