I was wanting to get a bigger throttle body on my 2004 Grand Prix GTP. If someone would tell me whats best so i wouldnt have to get bigger injectors. Also If there is any other inexpensive mods i could get that isnt so hard on my transmission? Thanks

Welcome
you wont need a bigger TB or injecters ever prolly.
but read this: http://www.grandprixforums.net/safel...car-17482.html
ps where in MN you at?

could you tell me the best place to buy a TB at and how big. Im new to modding so if you could jus explain a lil bit more in dept. Thanks

your TB is already BIG and really you would only need to make it bigger by porting it if you become pretty heavily modded,
read that link and it will guide you step by step on things you need to do before doing mods and what mods to buy to make your car faster.

i read the link and im at intens racing .com and am looking at the pcm's and i was wondering if you could tell me what WOT ignition timing tables are? YOu dont have to answer this ? but if you had a stock 04 gtp like mine what would you do for up grades that arent too expensive?

headers, 205 shipped to your door
open cone filter, 40 bucks
PCM 50-100 depending on where you get yours, intense and 3800performance got them
plugs 104's 15 bucks
and a smaller pulley and because your car is newer the S?C is better than the 97-03 models so your pulley need to be bigger and I would get a 3.5 or 3.6 pulley
and get gauges too, like a aero force and boost gauge and oil gauge.
shift kit from intense, 50 bucks??? not to sure on that one.
all in all around 400-700 depending on what you buy and where you buy it

on the pcm, any details you can give me on that b/c it has thos options to pick like the timing tables ect.?
08-25-2010
and the pcm's on both sites are like 200 plus 175 if you want to keep your pcm
08-25-2010
i dont know about the tables and such, but if you buy a PCM from them, wait till you get it and send you old one back to them and you get like 50-75 bucks back or what ever
08-25-2010
alright last ? as far as the headers go, 205, thats the size right? and the shift kit, do you know wat its going to cost to install it?
08-25-2010
thanks for answering my ?s i apprciate
08-25-2010
hey if you swapped your stock torque converter for a heavy duty one would that help keep your tranny from going out from a smaller pulley
