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: I want the car to be able to run a high 12 second ¼ mile while still maintaining an acceptable MPG and rideability. MPG i am shooting for is 16/26 at the LEAST. I would like more and believe i can get 18/28.
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!
Key:
* = An aspect i am decided on
+ = Still looking for more info.
- = Not finalized.
The Car:
Basics:
-Platform : 1999 Grand Prix GTP 2 Door.
*Induction: S/C
+Engine: 3800 modified crate engine. Stll looking into options. (ZZP, Triple Edge).
Under the Hood:
Supercharger
-Supercharger: Gen V. Would a Wipple be better? Iv only heard of them.
-Pulley size: 3.0. ZZP MPS. Maybe i can go smaller.
*Blower:Port & polished, Silencers filled.
*Upgraded coupler
Engine
+Block: No idea. All I hear is I should have a higher compression ratio (9.4). I have seen a few crate engines but I don’t know which Is best. The higher CR you go the lower boost you can run effectively
-Heads: Aluminum heads from ZZP. What do ported heads do? ported heads make them flow betterSupporting mods needed? Reduce mpg?
-LIM: Inlet ported. Do outlet ports give any gains?
-Pistons: JE forged Pistons. (zzp)
-Connecting rods: Forged. Where can I get these?
-Radiator: Oversized aluminum radiator (ZZP)
+Cam: Not sure. If they decrease MPG significantly I wont get one.
-Rockers: Nor sure, can you do a cam and rockers?
-Water pump: Upgraded water pump. Does this really do much?
-Pushrods: ?
-Thermostat: 180*
Transmission:
-Rebuild myself or use Triple Edge Performance. Go TEP
+Gear Ratio: Looking into benefits/ Downfalls of each.
-Input shaft: Forged/ Upgraded.
-Output shaft: Forged/ Upgraded.
+Differential: GM Racing Torsen differential. ZZP sells this. Not familier with real benefits
+Torque Converter: Pro torque. Not sure what stall yet.
-Transmission pan with drain plug.
Axles: Stage 2 ZZP. Are their better ones? SFPHQ bullet proof shafts I have heard are better, and the stock gm ones are good.
Electrical:
-Bigger Plug Wires (yellow or red)
-Spark Plugs: Autolite 104’s, .55 gap. coppers ware out quicker, is there a longer lasting option? Are Autolite XP iridium Spark Plugs better? the copper ones give a little better results, but have to be changed out far more often
-Ignition coils: MSD red. On our cars these do not perform any better than the GM ones-
-Alt Rewire
Intercooling
-Intercooler Core: Stage 3 Phenolic from ZZP
+IC Heat exchange: Short stack? Oversized?
-IC reservoir: Nut sure if one is needed or where I get one.
-IC Pump:
-IC pump controller, unnecessary but this is a fantasy build.
Fuel Delivery:
-Fuel Log: ZZP Billet Fuel Log (Chrome).
+Injectors: Not sure if i could get away with stock on a 3.0 genV set up. If i use bigger ones will it severely mess with MPG? the size of the injector will not effect gas mileage.....but you need to go big to have the ability to put more gas in the cylinder if needed. Also consider upgrading the fuel pump depending on how big you need to go.
-Upgraded/Shorter Dogbones??shorter dogbones are for if you drop the car.
-Throttle Body: Northstar (75MM). Or An LS1 TB. Not sure where to get the later.
-Air Filtration: AmsOil Cone filter. (should it be right on the TB if i am going to be running an IC.)
Exhaust:
*Headers: ZZP stainless steel headers.
-Downpipe: Stainless cat’ed downpipe. ZZP
-Catback: Borla.
Suspension:
-Control arms: From Red from ZZP.
-Struts: KYG ABX Adjustable from ZZP.
-Strut tower brace: Red from ZZP
-Sway bar: GMPP front and rear sway bar. From ZZP
Breaks
-Breaks: Baer Eradispeed Big Brake Upgrade. I can’t find other upgrade options.
-Brake lines: Stainless
-5th Break Line: Stainless
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
