Some really good info in this thread guys. I agree alot depends on how you want it to act best thing to do is find people with similar setups you are interested in and drive them around. A GREAT TUNE IS KEY. If you really dont want to dump alot of money into the car dont buy afr heads im sure they are great but totally unnecessary IMO. About upgrading the rest of the drivetrain thats on you but if you wait just dont drive it hard from a stop and you should be fine. Also gears is a MUST if you get a big cam. Good luck on you quest and let me know if you have any other specific questions.
