Update: 08/31/09 Small Additions and spelling corrections, goal list, injectors, fuel pump.
This is my fantasy build. I am convinced that one day i will construct this car.
Rules: There are some aspects of the build that I am decided upon. They are marked with an asterisk *. So basically if you try and sway my mind you will be beating a dead horse. Discussion on these things is acceptable though. I am posting this because I want POSITIVE feedback and input; also I want to put what’s in my head down on paper. Comments hints, tips and more options are greatly appreciated. Price is not an object for the most part, I man I don’t want to spend 20k on a custom mink interior or something weird. This is a work in progress, the first few posts will be updated and dated constantly with new information.
Goals:
Goal 1: I want the car to be able to run a high 12 second ¼.
Goal 2: Decent MPG i am shooting for is 16/26 at the LEAST. I would like more and believe i can get 18/28.
Goal 3: I want to maintain the "originality" of the car. The engine base, S/C induction, transmission.
Note: I am not expecting people to answer all of the questions i have (their are allot). I pose them as a note for myself as well as looking for input. If you see something you like or dislike let me know!
Note2: When i mention ZZP i am only referring where i have seen the item. The only item i want from ZZP for sure are their stainless headers. I will eventually get around to placing "cheapest price" links to all of these items.

Exterior
*Color: Base color will be back, secondary colors will be red and yellow. I will have a custom paint job, the paint job will be designed after a paintball jersey I have. It will not be an exact match but the idea will be the same. I will post the picture of the jersey later.
-Body: SD hood, front air dam, wing. Does anyone know of an aftermarket rear bumper?
-Wheels: Elbrus 104 or Nascar Sonoma. Not sure on size, at what size does performance decrease? I always thought it was bigger than 17.
-Tires: Yokohama ADVAN S4 It.
-Exhaust tips: SLP GTX Stainless. I know there almost impossible to find but I will try, or try to find something similar.
-Headlights and taillights: Stock, maybe I will upgrade to HID’s or some brighter lights. Not sure yet, I don’t want the problems I hear about surrounding HID’s.
*Grille inserts: Stock.*Exterior lighting (Underglow etc): None.
*Door Trim: None.
-Overlays: I will have the yellow GTP badge, “Pontiac” on the rear bumper and Pontiac symbol on the front bumper. Door sill overlay.
-Tints: Not sure yet.
-MISC: Any other exterior things I am forgetting that can be upgraded in this category?
Interior
-Black base. Want a custom interior but trying to make price realistic.
*Floor mats: Black. GTP embroidered in Yellow for the front back and trunk.
-Custom seats: Black seats with yellow centers. Yellow piping and yellow grand prix block lettering. The ones at the link are not my final choice. I want to explore other options if I can find them.
-Noise reduction: Dynamat will be used throughout the vehicle.
-Steering wheel cover: Black and yellow. (unless I get a different wheel)
-Heated seats: If the custom ones do not offer this as an option I will have to install them.
-Plastics: I want to see if I can get the dash and the plastic around the shifter in carbon fiber. PFYC used to have both but now they have neither.
-Steering wheel: Looking into different steering wheels. I can hook up mods to the wheel.
-Steering wheel buttons: The upgraded brighter ones by ZZP. (if I keep the stock steering wheel.)
-Stereo: Just a new deck, no subs. Still looking into options.
-Gauge mount: A pillar gauge mount (3 gauges). Looking into mounting more gauges, not sure where I can.
-Gauges: AeroForce Scan gauge, Wide band O3, Oil Press. Other 3 I am considering if I have room: Trans temp, boost, fuel press. (yes I want it to look like an airplane inside lol) Not sure what name brand to use yet. I do want red light and preferably a black back.
-Buttons, switches: I have seen some cars with them but have no idea which are useful or not. I think the 10 second Intense GTP has like 4 buttons I have no idea what they do. I want some any suggestions? Is a happy knob useful? ( I love buttons n switches lol.)
-Lighting: I want to upgrade all of the interior lights to LED’s. Not sure if I want to go red or yellow yet.
-Shifter: Stock
-Pedals: Stock
-HUD: Yes plz
-Sun roof: Yes plz
Misc:
HP Tuner
