The Story Behind The Car:

In late December 2006, I was originally looking for a "beater" car to drive while I could spend the much needed time to fix up my current ride I was using at the time. After many failed attempts of finding some type of 5 speed beater, I started looking at some automatic cars. Being an automatic however, I was looking for a certain type of car then.

Throughout high school I had always dreamed of owning a 1997-2003 Supercharged Pontiac Grand Prix GTP. I just always thought they were a cool car and wanted one. The funny thing is I had a friend that would always tell me the 1997-2004 Buick Regal GS was a much nicer car and they came supercharged just like the Grand Prix. However I told him that why would you ever want to own a grand pop looking Buick Regal over the sportier Pontiac Grand Prix? The older ones were in my price range at the time so I decided to start looking.

After many failed attempts of finding a Pontiac Grand Prix GTP within my price range, not beaten to hell, or extremely high miles, I started to look at other supercharged powered GM cars. Thinking back to what my friend always said about the 97-04 Buick Regal GS, I reluctantly started looking at those cars instead.

The first and only Buick Regal GS I looked at, which I now the proud owner of, I fell in love with it and knew I had to have it. It was owned by an older guy and he kept the car is fantastic shape inside and out considering the miles and age. After agreeing on a price which I never thought I walk away with, the car was sold.

The funny thing is I may have never owned this car or a Buick Regal in general if it wasn’t for the dead beat previous buyer. The car was listed on eBay however I caught it the last hour it was listed. There wasn’t enough time to get a hold of the owner, or to look at the car. So I let the auction go and continued my search. A few days later I received an email telling me the car was relisted. Also the seller contacted me saying the buyer was a deadbeat and to come over and take a look at it. If it wasn’t for that, who knows what I be driving now?

Earlier I said I was looking for a “beater” car to get so I could fix up my current ride at the time. However that soon all changed after getting my Buick. After discovering the decent aftermarket and performance these cars were putting out, I soon decided that this would become my project car instead. I had very simple plans for this car at first and never really expected it to get to the level it is today. However I am very happy at how the car has turned out and it will always be a part of my life for as long as I know.

February of 2007:

I ran into a deer and it took out my hood, passenger fender, head light, and some damage to my passenger front door. Thankfully the air bag didn't go off so I held onto the car and fixed it myself. I didn't get it fixed however till June of 2008!

March 2007:

Being that the stock 4T65E-HD transmission in my car out of glass, I lost 4th gear in my transmission at around 135K. I had only put 6K on the car and already it needed a new transmission. I didn’t want to have to worry about the transmission for the life of me. So I contacted and traveled up to Dynotech Performance in New York with my car. They installed their Stage II Racing Transmission rated at 500HP with a 2750 stall converter and changed my gear ratio from the stock 2.93 to 3.29. They also installed my upgraded motor/transmission mounts and GTP engine cradle support bushings. These are much stiffer them my stock Regal ones. After I got my car back it felt like a totally different machine. The shifts were hard and quick and as well the acceleration was definitely quicker. The only thing that brought me back to reality was the totally cost of the transmission and labor. The bill came to $4,000 dollars. It was a bit expensive however well worth it for the long run. At least I can say the transmission cost more then the car did.

July 2007:

My original plans was to keep the mods simple. However I came across a member on a Regal forum I was on that was demodding and going turbo on his Buick Regal. The price he was selling the complete de-mod package for was well worth it. So this is what began "The Big Upgrade" to my Regal.

September 18th 2007:

Before I was to have "The Big Upgrade" done to my regal in later September, I wanted to run my car at Atco Raceway NJ first to get an idea of what the upgrades would do. I was pretty nervous however the guys said I did pretty well for it being my first time. My car at the time only had a beefed up transmission, fender well intake, and tune up parts so I was happy with the outcome. These cars do around 14.8-15.0 for a stock ¼ time.

This is what I ran the first time at the track:
• 1/4 = 14.594 @ 93.39mph on Street Tires 2.189 60 Foot

9/22/07 to 10/20/07:

I dropped my Regal off at another W-body owners house up in Lancaster Pa to have "The Big Upgrade" completed to the car. He started working on the car in early Sept and was finished towards the end of October. The reason it took a month was due to shipping delays, and defective products. Once the car was completed however, it was like a totally different beast.

Pictures of day by day build

"The Big Upgraded" consisted of the following parts being installed:

• ZZPerformance Ported Inlet/Outlet Eaton Gen III Supercharger with Modular Pulley System
• ZZPerformance Stage III Full Stack Intercooler and FMHE
• ZZPerformance Ported Lower Intake Manifold
• Cadillac Northstar 75mm Throttle Body with LQ4 85mm Maff Sensor

Here is a video I took of my car in early September. At this point I already had the Dynotech Transmission installed about a month ago. I was showing people how much quicker it shifts over stock. I started at about 20mph. Now however my car should be a bit quicker at accelerating after the upgrades are completed this week.

Almost Stock Regal Pull From 20mph

your car is awesome, I still want one. :)

GeforceXtreme 10-17-2007 09:52 AM

Thanks for the comments guys. The install is almost done. The IC hoses are ran and all he has to do is install the Racetronix fuel pump and we are good to go after a good tune.

I knew I couldn't stop after seeing these pictures weeks ago:

GeforceXtreme 10-18-2007 01:43 PM

I am picking my car up this Saturday. I can’t wait. I haven’t been in the driver seat since Sept 22th. He just has to fill the IC system and install the Racetronix fuel pump.

1988 Olds 10-18-2007 03:18 PM

Looking good man. Lets got tear up the streets Saturday night lol

Honest_Bob 10-18-2007 06:23 PM

I love those cars. My coworker has a SSEI Bonniville. I'm guessing its nearly the same motor right? The thing is a monster on the highway. Sits at like 3k rpms at 80mph.

GeforceXtreme 10-24-2007 04:42 PM

I forgot to post this since last Saturday:
Well today I went up and got my car and man was I sure happy. The thing is so much louder then stock and the throttle response is so touchy. When I got to Dave's house two other local members were there to see the car. Dave was more then nice enough to go over the entire car with me part for part and also go on a few test drives with me to make sure everything was ok. After that was all done we loaded up all the stock parts and went on our way home. The car did great the entire drive home on the highway and I couldn't believe how little gas I have to give the car for it to pickup speed fast. When I got my car back home it was a big hit around here. The exhaust is very boomy. When I was unloading boxes out of the car the boxes were vibrating in my hand. I love it because its loud enough to make a point but inside the car its quiet enough for long highway driving. When the transmission goes into lockup mode and drops down into the 1,500-2,000rpm range that is when it’s the loudest. I still can’t believe how much of a difference the car is from the last time I drove it. The gas petal is so much more responsive with the northstar it’s crazy. Also the supercharger stays so much colder compared to stock. Before the supercharger would burn you if you touched it. However on the long drive home I left the car running and the supercharger was cool to the touch. The car was a big hit around where I live. People still couldn’t believe that the work into the motor was in a Buick Regal. It is such a sleeper while sitting still. But once its running and you give it some gas its another story.

Took some quick pictures of the final engine bay.

GeforceXtreme 01-04-2008 09:31 PM

What the car does in the first video I ran a 14.5 1/4" time. At the time all the car had was a tune up, FWI, and the Dynotech Trans. I floor it around 20mph and as you can see my tires don't do anything.

Video of my almost stock Regal:

On 12/31/07 when I was leaving for work I saw my digital camera and being it was new years eve I said what the heck. To my luck the road I was on opened up and I was able to get on it somewhat. The video below is my car now with all the upgrades listed below and running stock WOT timing (keeping it safe till I get my tuner in). I start to get on it around 20mph however I was keeping an eye out so I kind of eased on the gas. Of course the tires still spun. The windows were up in the car this time so it may not sound as loud as the last video.

Video of my modded Regal:

It’s funny how long it takes the car to get moving when it was almost stock in the first video. I wonder what my car will be like with a 2.7 pulley and a better tune? The car to me I feel is more then fast enough already. Won't be doing anything else till spring.

Tiny 01-04-2008 10:07 PM

Thats pretty interesting. You can definatly see the difference in acc. from the stock to the modified video. That would be a neat car to catch some people napping with. I would have never expected it.

GeforceXtreme 03-17-2008 11:37 PM

Well for some time now my driver side CV joint has been making noise but it has been too cold to do any work and also just way too busy. Another reason I was holding off on replacing the CV joint was to also purchase the rest of my parts like new struts, springs, and brake upgrade. Well early last week it finally snapped in half. So the car is now parked waiting for the upgrades to come in. At least now I won't have blown as heck 144K struts anymore. Should handle somewhat better. Once the car is fixed I plan to start tuning some more and drop down to a 2.8" SC Pulley and off to Atco to see if it runs faster the 14.5 last Sept with a lot less mods heh.
