1. Some definitions of some of the accronyms you may see or hear.
ABS= Anti-Locking Brake System
AWD = All Wheel Drive
CAI= Cold Air Intake
Cat= Catalytic converter
CV Joint = Constant Velocity Joint
DIC= Driver Information Center
DIY = Do It Yourself,
FWD = Front Wheel Drive
FWI = Fenderwell Intake
IAT= Inlet Air Temprature
KR= Knock Retard,
L32= S/C 3.8L replacing the L67
L36= NA 3.8L V-6 used in the 97-03 GPs and other GM models
L67= S/C 3.8L V-6 used in the GTP, Bonneville SSEI, Buick Regal GS
MAF= Mass Air Flow sensor
NA= Natural Aspiration
PCM= Powertrain Control Module,
RWD = Rear Wheel Drive
S/C= Supercharged
TC= Traction Control
TPS=Throttle Position Sensor
PCV= Positive Crankcase Ventilation


2. Q. What are the differences between the GT and the GTP?
A. The only differences between the GT and GTP are the powertrain equipment. GT uses the L36 with a 4T65E tranny and PCM written for the NA motor and weaker tranny and the GTP uses the L67 with the 4T65EHD Tranny and PCM written for the S/Cd motor.

4. Q. Can I swap my "catfish" SE front bumber cover and rear bumper cover for the GT/GTP bumper covers?
A. Yes you can. You will need to use a couple of brackets to properly secure the new pieces. The brackets are cheap and can be found at any GM dealership that sells parts or you may pull then from a junkyard.

5. Q. What Oil is the best?
A. That's a highly debated question. Synthetics are far superior to regular oil. Synthetic blends are about half synthetic half regular oil. Some people swear by Mobil 1 synthetic. I however believe in the differences between the brands is minimal and as long as you change your oil and filter on a regualar basis is sufficient.

6. Q. How often should I change my oil?
A. The standard answer is every 3,000 miles. How ever you should take a look at what type of driving you do. If your vehicle is on the highway running constant speeds for 75% of the miles you could easily stretch that out to 6,000 miles. But if you are driving in desert conditions ie. high heat and lots of dust then change it every 3,000 miles. If your vehicle spends most of it's life in stop and go city type driving, change your oil every 3,000 miles. If you take your car to the track and beat on that happy pedal alot then change it every 3,000 miles.

7. Q. A friend of mine has car X and I have car Y who will win in a race?
A. The only way to tell is to actually race. Knowing how to launch your car and when to shift is the biggest factor. In other words the driver makes or breaks the race. Alot of high performance cars require great driver skill in getting all that power to connect to the pavement. If the tires are spinning that car is going no where. Mean while your slow car is halfway through with the run.

8. Q. How fast is my car in the 1/4 mile?
A. There are lots of variables when it comes down to 1/4 mile performance. Altitude, temprature, humidity, tire pressure, vehicle wieght, driver skill, track conditions the list goes on and on. The only way to know is take the car to the track and find out. Even then you'll have multiple runs on different days and get different results. Even dedicated car magazines will have varying performance data do to the different conditions and drivers.

EXHAUST MODS
Hercman's comments
"The only way to get a mean sounding exhaust will be if you do a cam swap.

The SLP loudmouth is just that it's loud. Remember you have a V6 and just adding in new exhaust will never get you that V8 sound. If you want to do a cat back exhaust your best money spent would be to go to a shop and have one made. Alot of us use Flowmaster 40 series. I have the super 40s and love them. There are a few other brands but for the most part FMs seem to be the favorite here.

For mufflers go to ebay and use performance peddler. They have bout the best prices out there. I think you can get a pair of muffs for right around $100."

Thunderbat's comments on Flowmaster Hushpower muffs
"I have to admit that I had my fears about putting this muffler on the car cuz I was afraid it would make it as quiet as the stock system...this is a chambered muffler but has a case only about 5 inches wide, or about as big as you catalytic converter only longer. Much to my pleasant surprise, when I cranked the engine the exhaust note seemed virtually the same as it did with the Cherry Bomb, a nice low rumble. Heavy throttle application still yields a robust roar but with little or no back-rapping when you back off or downshift...but most important of all, the interior drone is so low that its almost undetectable...turning on the stereo wipes it out completely. This is an expensive muffler ($124 from Jegs) but it is T409 stainless throughout and it hands down does the job. I would highly recommend this Flowmaster to anyone"

Rook on Flowmasters and the 3100
"Flowmasters don't come with tips and will run you $60+ each. From those that have played with them on a 3100, I hear they sound slightly deeper than the 3800s."

GTP4LIFE's comments on the SLP Loudmouth
"i have the original SLP Loudmouth and it is horbal, i mean it is really throaty i have had a few people ask if its a v8. but i can turn the radio up all the way and still hear it clear as day. theres no way to talk on the phone and drive"

vmschumacher's comments on the hushpower 2
"I have the flowmaster hushpower 2 muffler w/2.5 pipe and resonating silverline tips. Best sound I have EVER heard in a mildly modded GTP, EVER!!!!
My friends thought I had a v8 with the rumble."

1BAD97's comments
"A 3" downpipe without a cat will make your exhaust sound very nice with the stock mufflers/resonator. That can be had for less than $300 and is a bolt-on deal. I have stock cat-back (resonator in place) with 3" catless DP and PEM's, sounds pretty damn good to me (of course the XP cam plays a small part in that, lol) Not unreasonably loud, but mean enough to scare ricers, and it's very obvious the car is cammed. Just offering an alternative to throwing poopy sounding mufflers (which is ANY aftermarket muffler really) on a GP. The 3800 is just not a good sounding engine (as in, will never sound like a stang GT), nothing can fix that so don't go broke trying."

Supporting mods for a 3.4" pulley:

CAI/FWI
U-bend delete
3" D/P
PCM
180* T-stat (drilled prefered)
1 heat range cooler plugs (copper core prefered)
A scanner is highly recommended in order to monitor the KR that will be introduced with the smaller pulley.

The facts on a GT build:
(Posted by Chico)

I get a lot of PM's regarding building a GT so I thought I'd post here my opinions,first off as most know the common weak link in GT's & GTP's is the trans. and do'nt be fooled that the HD version is a whole lot better,now on with what I've found the 3.8 n/a can be built to run mid 13's with the following formula 1-cam either zzp gt1 or gt2 with a 3200stall convertor or Intense s/1 n/a cam ,it would also take a bump in compression to 10.5-1 by milling the heads 30k also a mild port job will help,as far as intake I would suggest a 3" FWI Iknow a lot will say 4" but remember on a n/a you will need air velocity not volume,now come to exhaust you will need a minimum of PEM's and 3" dp and hi-flow cat or race pipe if you can,another product that has potential is the zzp powerlog& rearported mnfld of course you may want to go to headers and I'm not saying not to it's just they are to expensive for the gain,of course you will need tuned pcm and most companies will tune for your mods,now a lot of guys just want to hang with stock GTP's at high 14's so aside from the head work and the cam (go with rocker's) you need the same mods ,I would suggest before modding that all your maintenace issues are resolved and your trans. is serviced and in good working order.

CATALYTIC CONVERTERS

Cats or no cats that is the question.

Federal Law stipulates that any and all emissions controls that came on a vehicle must stay on a vehicle. Just because a certain jurisditction doesn't do emissions testing doesn't make it ok to remove the cat. Say your in a little podunk town and the local LEO is having a bad day and sees a car with super dark tint, loud exhaust and a burned out tailight and decides he's gonna harrass em. Car gets pulled over driver gives some attitude and next thing you know Mr. LEO is looking over the car with a fine tooth comb and what does he find? No cat on a car that's supposed to have a cat. That right there is a federal offence and is a big time fine.

Ok legalities aside

On a DD removing the cat doesn't gain enough hp to really feel a difference. On the track where every 100th of a second does it will. With the availability of aftermarket high flow cats compared to the cost of an OEM replacement if your cat is clogged and need a new one get the aftermarket. If your cat is fine the Ubend delete will be your biggest gain from the cat back. But if your gonna go that far many vendors now offer 3" Downpipes with cats already welded in for cheap.

If you have to ask catless or catted chances are you really don't need to run catless.

Only time I'll condone catless is one car is only running on the track and two your cat is clogged and your wallet won't allow a replacement on your only vehicle at this time. But in this case only as long as it takes to get the replacement not as a permanent fix.

As much as people hate cats they really do some good. The 70s gave cats a bad name but they have come a long ways since then.

gas requirements are 93 octane? whatever the premium in your area is rated at

More info can be found here .

L67 - Series II Supercharged 3800
L26 - Series III Supercharged 3800

Gen 3 - Refers to M90 generation used on Series II motors. Slight design changes from older gens such as the ones on the 3.8 Tbird Supercoupes.

Gen 5 - Refers to M90 on Series III motors. The supercharger has a larger opening in the base, smaller silencer slits, and a different rotor coating. It's more efficient than the Gen 3 at making boost without heat, which is why so many people try to get one. They also don't generally need porting whereas Gen 3s do.

LG8 - 3100 motor.

wheel lug spacing and offset

any wheel with 5x114.3 or 5x115 bolt pattern and 38-45 mm offset should work just fine for the 97-03 GPs.

HOW TO PROGRAM A FACTORY REMOTE:
IMPORTANT: Before entering programming mode, have in possession all of the transmitters you will be using on the vehicle. Once you program the transmitter, all previous codes will be erased from the memory. The other transmitters will not be functional until you program the transmitters again.

1. Remove the key from the ignition.
2. Close all of the doors.
3. Remove the “ MALL PGM” fuse from the fuse panel. Use the legend on the fuse panel or owner’s manual to properly locate the “ MALL PGM” fuse.
4. Insert the keys into the ignition, and turn to the ACC position.
5. Turn the key to OFF and then back to ACC within 1 second.
6. Open and close any vehicle door. A chime will be heard when the system enters the programming mode.
7. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds. IMPORTANT: After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming.
8. Repeat the previous step on each additional transmitter to be programmed (including any existing remotes).
9. Remove the key from the ignition.
10. Install the “MALL PGM” fuse.

(just so everyone knows if you use a remote that was already used on another vehicle it will lock and unlock and pop the trunk on both vehicles)
