After rewiewing that nitrous would not be good for my ZZ4 and the roller rockers dont seem needed then either. I have decided to lay off of performance mods untill i get out of college. At that time I will purchase a new daily driver and have my truck around for fun. At that time it seems to me to go all out and just bore and stroke the motor. I have no idea what would be needed for this at all or how much it should cost. If anyone could tell me all of the things that need to be done to bore and stroke an engine and also how much it would cost that would be greatly appreciated. Since this is going to happen in the future just forget about saving money and just say what your ideal for this situation would be. This way I can have a dream motor to look forward to someday.  

Run the zz4 untill the warrunty is off.  

I applaud your plan to first graduate.  Good for you.  Spend some spare time while in school to bone-up on various combos, etc. for your "dream motor."  There's no shortage of literature to learn from.

Don't get overly caught up in the "bore and stroke" mentality.  Typically, the only time you bore a motor is to clean up the cylinder walls from normal wear.  Stroking or destroking an engine is a method to increase or decrease engine size and its operating characteristics.  This practice has become very common; but, nonetheless it takes forethought and planning and is not always the best route to take (plus it often adds $$ to the project).

Best advice I can give someone in your situation is to establish a plan (what are your trying to accomplish/achieve?), develop a realistic budget and talk with people in the know.  Go visit a drag strip.  The cool thing about drag racing is that spectators can roam the pits.  Most racers will gladly spend time talking with a novice who has a genuine interest in learning.  Also, for a newcomer the best route is to often build the biggest motor you can afford.  Few things replace displacement - and those things that do often come with a hefty price tag.

Good luck.
