need help with my 03 bonneville ssei
i just got my car like a month ago and it is the first supercharged car i have had so i am a total noob. i have installed a 3.25 pulley with a gatorback belt, intake, low temp plugs, or at least i was told they were. i will have to check what part number ther are but i know they are ngk'*, and i took off the cat and resignator and put in a 2.5 inch pipe in its place. i dont have emmissions in the county i am in so i can get away with that. One question on that. is that the same or as good as getting a hig flow cat? and i plan on getting a pcm from intense racing but i wanted to get eveything modded before i got a pcm. what else could i do to make it faster. i know that ne cams help but i really dont know anything about that like what kind to get or what they do actually to help. i think that they open the valves more to get more horse. well any help i could get would be greatly appreciated.

Other than that, congratulations on the car and the mods! Looks great.
First take that 3.25 off and put a 3.4 in it'* place. Get rockers for some more top end. If you want to run the 3.25, you'll probably need a cam and headers. Ofcourse an intercooler is the best way to start and then go from there. Main thing is to get a scan tool so you can keep an eye on what'* going on with your motor. All cars react differently. I had rockers, headers and still couldn't run a 3.25 on my GTP. I also had 5*KR with those mods and a 3.4. Now on my Bonnie I run the 3.4 with just the minimal mods and see about 2-3*KR max.......every car is different.
