I have a stock 4.6 in my 2000 gt, I dont have a lot to spend at the moment but would like to gain a little power, I am looking at underdrive pulleys,throttle intake,cold air intake,and the shaker system, but I am not sure what would be the best. Long term I know a twin turbo or supercharger would be ideal, but I was also wondering if I would be better off saving for a bigger enginge alltogether. what I really would like to know is what I should do to the car step by step, what to invest in first, and slowly build her up into a mean machine.

 

Dont worry about getting a bigger motor. You can make good power on the motor you have (they love boost). However, right now, best bang for you buck would be a full exhaust system from headers back. Longtubes, o/r x-pipe, and a good set of mufflers (recommend magnaflow, they give you some of the best power gains of many of the aftermarket mufflers). I would say you could gain upwards of 50hp or so from that. I may be being a little generous, but that would show higher gains then the bolt ons you listed.

 

Here is an affordable option that will provide 20-25 RWHP or the Steeda Power Pak Stage 1 14-17 RWHP or the real deal stage 3 which will get you upto 40 RWHP.

It all depends on your preference. Do you want to plug and play now or do you want to wait? Remember when adding all that power with a supercharger you are going to want to upgrade other aspects of the car to keep the wheels planted.

This kit above is a great option and you will definitely not be disappointed. Let me know if you have any questions? Just the CAI alone will give you an extra 7-10 HP.

PM if you have any questions or additional support.

Thanks
