About 50 people have sent me this video. Thanks for the shoutout. Believe it or not Bo’s car is pretty mild. Mine makes 800+ with not much else. Stock bottom end. Engines are very tough to kill.

We still have our 2003 GS that now my son drives back and forth to school. Ported supercharger, ZZP Headers, high ratio rockers, 3.3 pulley making about 320 hp when it has the performance tune and high octane gas. Detuned, makes 290 all day long, and averaged 27.5 mpg driving 80 plus, for two days on a trip to Florida. Now has 187,000 miles and doesn't burn a drop.I love the car too much to part with it. Plus when I drive it, its fun to roll past people who think its a slow beater.

This car is proof that you don't need the best looking car or an extremely fast car as long as it's clean it has my respect, I never would have expected to like this car but it's amazing how some wheels, suspension, and some clean paint can make any car look fantastic. Not to mention it has 400HP!

Miss my 3800 every day. I had a 2dr GP and it went like hell! So much faster and built so much better quality and a lot stronger than my now Challenger, no joke! Glad to see there's still some 3800s around!

I love that people are starting to discover this generation GS. They were amazing cars and for the era they flew . Then the folks that upgraded them man did they have something special. That 3800 was bullet proof !!!!!!

I remember when these were new on the lots - not many were produced with the supercharger, but mainly with the NA v6. Nice to see someone keep one on the road and have some mods thrown at it.

Also am I the only one who was so worried about the 4t65e every time David hit the gas? 😂😂

I absolutely love the Buick Regal GS. I miss my 02 Regal GS. The only downside about them is the transmission can't handle the amount the torque they put out. The 3800 V6 is bulletproof.

This is the cleanest Buick I've ever seen. The aesthetic and the mods are just perfect.

My dad drove one of these when I was in high school - it was the car I learned to drive on and took my drivers test on the day I turned 16. My parents brought both cars so I could drive home on my own, in the Regal. At the exit of the licensing place, making sure my dad was following directly behind me in my rearview mirror, I turned off traction control and laid a big smoky burnout. I looked back and saw my dad nervously chuckling, maybe a biiit upset. But that was a fun car. Quickest sedan to 60 when it was new at 6.4 seconds. Fun times were had in that Buick.

Fun fact: Those "luxury" seats are actually from an 05-08 grand prix gxp. Love the video!

My favorite sleeper is my daily 06' Accord Coupe 6spd manual with a J35a7 Honda J-Series V6 engine, 69/68mm Turbo on 7.8psi making 560whp and 470wtq. Obviously biased but we built it using all of our HLP Products (HalferLand Performance Products specializing in Honda J-Series Performance Parts) and this setup alone has over 35k miles on the engine and no issues but trans thus far 😎😏

What do you guys think of this Buick? Side note my mini documentary comes out Sunday - Car Culture:2012 vs 2022.

The Pontiac Bonneville back in 88 with the 3800 was nothing to be messed with. It had its issues with the egr system, however, it always set you in your seat when you rodded on it.

Bo's Regal has been a fan favorite of ours for a while. Glad you enjoyed the ride!

ZZP is still killing the game. Buying stuff from them, seeing the shop in person amazing memories. My cobaltSS back in the mid-2000s made the same power as this car. ZZP just constantly improved on platforms for cars most wouldn't, and it's why a lot of us on the cobaltss fourms back in the day loved seeing them post and interact with us.

That car is sick. Cool build. I had a 2000 Pontiac GTP years back with a cam, pulley, etc… and that thing was a serious sleeper.

Builds like these are why I watch channels like TDIB and Roads Untraveled. Unique unique unique.

2003 Regal GS Joseph Abboud edition was the first nice car I ever owned. Prior to that I had a 93 SHO I purchased for $250 that was all rotted out and the guy who sold it to me stripped out the sub and amp that came stock. The SHO was quick and a little peppier but that Regal was special. I wanted to get a mercury marauder but the prices were insane. When my SHO died and I was shopping for a car in 2007. A 2002 Marauder with 100k miles on it was going for about $15k. I was able to get my mint special edition Regal with only 13k miles on it for $10k. That car was special. The only mods I did were full exhaust, smaller super charger pulley, some intake work and tune. The look on 350z and mustang owners faces was so gratifying when they got left in the dust by the grandpa mobile. They would laugh at me when we lined up and would have an utter look of confusion on their faces when they shifted into second and I rocketed away. The gears were sooooo ridiculously long but that was part of it's charm. You couldn't floor it before 40mph or the tires would break loose but once you had traction it just pulled forever. No pesky gear changes necessary. It used to be able to run the quarter mile without shifting out of second.... I'm sorry if anyone actually read all this as there is no point aside from the fact that it was an extremely special car. The turbo swap wasn't necessary and I remember the guys who did it were disappointed. The same amount of money for the turbo setup could be spent elsewhere with much higher gains. I miss that car so much. She took all the abuse I could throw at her without an issue. It was the sitting that killed it. She needed to be driven and I failed her. I wish I could go back in time and do things differently.

About 10 years ago these and their series 2 3800 sc siblings were some of the most fun on a budget you could get.

This is absolutely one of the best 6 cylinders ever made. I've known people to get 800+ hp. Out of these 6 cylinders. They are also very much the torque monsters of the v6 world.

I used to drive the LS version of this car in college back in the day. That 3.8 v6 engine is extremely an underrated bullet proof engine. So comfortable torquey as hell and easy to drive! Only bad thing was the exterior paint finishes on these cars was trash.

Those 3800 supercharged engines are something else. I have an 04 Impala SS with the 3800 supercharged and i has about 150k miles on it. It's worn out, idles up and down, leaks oil from the valve covers, has a coolant leak, but it still runs smooth. Doesn't smoke , knock, or tick. I put a K&N cold air intake on it and it gave it a noticable boost. My trans probably needs a rebuild also but the car is still a beast. That damn angine will out last the body that's for sure.

I had my regal for 5 years. same color as this one. It was my baby. Borla exhaust, smaller pulley, and a bunch of other mods done to it over the years. I wrecked it back in june, but i miss that car to this day. Great to see a regal on this channel.

Also, I will NEVER forget that Sleepers video. That's what first got me interested in the L67 3.8L V6. One of my first cars was a 1989 Chevy Beretta GT with a 2.8 garbage V6 that had blown head gaskets, and I REALLY wanted to swap in a supercharged L67, but I was 15 years old and didn't have any money. I grew up to become a car detailer for multiple dealerships (as I moved alot), and one of them was Ron Slivka Buick in Brandon, Florida (REAL close to Tampa). I drove many GS Buicks and Rivieras, so I grew to really love the L67. This was back in 1999 or 2000. I REALLY wanted to swap the 2.8 out of my Beretta for a L67 and turbocharge it eventually, but I never got the chance to due to me being diagnosed with Hodgkin's Lymphoma and being given 90 days to live. Obviously I outlived that estimate, but I have always still been left with the hunger. Right now I am on my 69th vehicle since then and I have a 1997 EJ8 Honda Civic coupe with a fully built LSVTEC turbo that makes 709 whp, and I also have a 2004 Acura TL that I am currently turbocharging, so that'll be fun too, with a six speed manual swap. Something has always drawn me back to these L67 swaps though...

The Boost Moose! Bo's Regal is an absolute riot. It was hilarious watching people pull off for home when we were at TOTD. Haha

Just bought my first supercharged 3800, 07 Grand Prix GT. Can confirm, this front wheel drive car is fun to drive, and the weird exhaust sound throws me back to my high school days in the 90's when everyone was rockin' their dad's LeSabre

I had the non GS Regal with the N/A 3800 V6. It was surprisingly quick and had tons of torque down low. This turbo GS is really unique. Great video!

My wife currently has one of these, a 2002 that I've asked her to see about doing a couple things to, but all it has is a turbo kit and valve springs? That's impressive

For a moment, I thought the thumbnail said 400hp Turbo Brick and had a good laugh. That said, this Regal is something else and I'm here for it.

Glad to see these old boats getting some love❤️ I have a soft spot for a lot of old Buick’s

It's actually getting really hard to find those supercharged W-Body cars in decent condition. The 3800 sounds similar to the turbo 3.8 in the Grand National. This is on a similar sleeper level as the 80s Buick T-Type, especially the turbo limited which had those pillow back bench seats, column shift and chrome trim but had the Grand National drivetrain.

My grandparents had a 2001 Buick Regal LS and the 3800 series 2 in that was surprisingly quick N/A. The right was very comfy too, I always wanted to drive a GS, that extra 40hp and 80tq would have made quite the difference.

I love the GS, it was a really quick couch. My neighbor had one in black, and it was the more modern grand national, I know the GNX was badass, but the GS was definitely the definition of a sleeper

3800 series are monsters. They put out some good numbers stock. I used to piss my step dad off in my 98 oldsmobile intrigue. He had a stock mustang gt, I had an intake... he couldn't gap my 3.8. The engine and transmission in mine held up to 230k abusive miles and still ran strong when I sold it. I never drove it in drive. U could slam gears in that thing and she took it. Used to start in first, slam second n smoke the tires. Be doin 55 and bump it down to 2nd n pull up to 80. That car took AL kinds of abuse and never had any problems other than water pump.

No car has surprised me as much as a mid 90's (I think) Taurus SHO that I drove working at a body shop to get an alignment. That boat was moving.

I did this exact thing in highschool, and it's what started my life as a car guy. Gold 2001 Pontiac grand prix gtp with a 6266 ebay turbo kit and all the juice zzp could put at it. Stock 5 spokes fit 225 m/t without an issue and looked like stock tires so it was troll city considering everything from the outside was stock. Full cloth grey interior that smelled like a cigarette, and I never pulled up with less than 2 people in it. Worked on it with the local good ol boys since it was a small town, but we made sure to pull up at shady side every weekend and troll anything and everything in the parking lot. And we weren't worried about blowing anything, at the time these cars could be had for 250-500$ all day long at the auction, so we would just buy another car if stuff broke on the first. We actually killed a couple regale and Bonnevilles before settling on the grand prix. It was the lightest of the w body cars and it took 5 minutes to strip the interior of one and turn them into dirt slayers. God I miss these things. Now a good example is 5k lmfao.

I work right next to ZZP on 28th st and see this car sitting out front all the time. interesting to see it in my recommended it always catches my eye and they always have something cool parked in front.

I have one and I love it. I've actually beaten some WRXs with just exhaust and a mild tune done to my Regal.

Damn that Regal is clean.... first time I'd choose this generation over the G Body Regal.

Dang this is a GEM! 12 sec quarter mile! SSSHHHHEEESSSSHHH! My favorite sleeper is the Mitsubishi Galant VR4.

My first car was a 1996 Buick Riviera with a supercharged 3.8 V6. 2 door coupe black, and I did all the things an 18 year old car kid would do, tinted windows 20 inch rims and 2 12’s/ 2 15’s with 3000 watts rms of power in the trunk that shook the block lol. Buick still to this day is/and was my favorite car I could earn enough to own being a lower class citizen. Love Buick’s and still miss that car to this day.

I really like and appreciate builds like this. It's different and unique. Makes me want to do something similar... Buick has always been slept on though hence the name "sleeper".

As a joke, me and some friends took my 2001 Chevrolet Malibu LE, Slapped a Turbo on it, did a bit of work to the suspension, and garage fabbed an aftermarket exhaust to the car, thing sounded weird af but it was quick as hell. The ONE and only thing I still crack up about that car to this day is getting rolled up on by some kid driving a 2006 Subaru STI, him rev bombing at an intersection and me smoking him at the next light from a dig. The light we raced from to the section we ended at was roughly 1/4 mile and I gapped him by about 3 to 4 car lengths. I'll never forget his expression rolling up to the next light, I could feel his mixed emotions just glaring at me. He was genuinely intrigued by my car but also very pissed off that he got roasted off the line and gapped by a 2001 Automatic Malibu LE. At that following light I caught a glimpse of him head turned, head cocked sideways in a world of bewilderment like "wtf just happened?" Lesson is, NEVER underestimate a grandpa grocery getter. Doesn't take much to turn them into import slayers.

I love this build so much. so clean. one of the coolest cars youve reviewed in a while

That 3.8 V6 is VERY respectable. One of the greatest engines ever made. Bulletproof reliable in stock form and capable of putting down serious power when modded. What you've got there is essentially a FWD GNX.

This is an amazing build. Total respect!

I inherited my Mom's LeSabre SE, always garaged. I was gonna sell it for $1200, it only had 88K mi on it. I thought I would take it to the track and blow it out before I sold it. It ran a 14.5 second quarter mile first run. Now I have decided to keep this car.

For those that don't know this engine, do the research, it's very similar to the regal gnx engine. There was a huge aftermarket support through the 80s-00s, a lot of those parts and all that knowledge is still available.

I had a 1993 Buick road master that with the 4 speed trans and it was hilarious. It was the a limited and had a 5.7l LT1. We went to the junkyard and got a big ass turbo off of an old flatbed. The road master was rear wheel drive and it was ridiculously fun. We put an exhaust cutout on it so that I could drive it around with the nice quiet exhaust but if I wanted to mess around I could flip the switch and have open exhaust a few inched from the downpipe. I miss that car to be honest. I should have never sold it. It had super comfortable seats, power everything, and the stock speakers were actually great. I put a single Walmart 12" sub in a sealed box in the trunk and got one of the cassette tape to auxiliary cord adapters. I would not hesitate to buy another one if I find one in good condition. The one I had was an old man's car and he had every single service receipt from when he bought the car brand new in March of 1993.

Having boost ramped in is probably a hell of an upgrade for transmission life and tire spin.

I had a 2000 Ls with the 3.8 and with no supercharger on it the thing still moved. I loved that CAR 🚗

I had this, had a beefed up the Supercharger. Was such a fun car. I was pushing 350+, I loved the whine from the Super 👌

The 3.8(3800) engine in the regal, grand prix, Bonneville,etc. was a very strong engine. These cars took a lot of sport cars by surprise.

Thank you David for such great presentation! One of the best V6 engines ever built. Cheap, reasonably lightweight, compact, and highly tunable, ... 😳 My favorite sleeper " Chevy SS , obviously stick (swap SS emblems for Impala emblems)😀

When I was younger I had a 98 Eldorado ESC, I sent the heads out got ported and polished and replaced the cams, some other things. Long story short that 4,000lb land yacht hurt many mustang owners feelings. It was priceless

I had a few of these back in the day. The key to unlocking power is getting rid of the u bend in the exhaust. Should be your first mod.

I had a 99 GS Regal. It was awesome. It was BONE stock and I raced a Honda Civic and beat him big time. There were some upgrades for the supercharged engine. 1) small pulley for the supercharger. 2) U-bend delete for the exhaust. 3) flash the ECM for more performance. I had seen some other Regals and Park Ave Ultras that were modded and they were pulling around 400-500hp. It was crazy seeing these cars doing some road ripping. 😳🤯

A friend of mine in college had the supercharged regal. That thing could roll out!

I HAD a 1991 Buick Regal 2dr custom coupe. I liked that car. It rode really nicely, comfortable.

I love Bo’s car. Those look like Grand Prix gxp seats. Awesome platform, owned a GTP comp g myself.

Owned an 02 gs for almost 10 years. smaller pulley, rerouted cold air and head cover breather. Best car i ever owned, Could pass 80% of cars rolling down the highway but if you stayed out of the boost and babied it she would get a little better than 30mpg

I myself would like to think I drive a "sleeper". It's a 2016 Chevy sonic RS, stage 2. All zzperformance parts. Really fun car around the city. Hope you do a review on one soon, would love to see it. Great content, you're slaying it dude

Back in the 90s I dropped a 370 hp 455 V8 and turbo 400 tranny in a 69 Skylark. It went so fast it became airborne! I could have been killed!

The GXP seats make a huge difference

The Regal among other GM cars at the time were actually aimed to attract younger buyers way from the imports. Problem was they couldn't really get passed the image of Buick and Oldsmobile being for older folks. I had an Oldsmobile LSS back in the day as a young adult and loved it. Perfect sleeper and so well built.

Finally! A 3800! 😅

Prime example of why I still love this channel over the years you have stayed true to what like

Love uncommon builds like this!

At the beginning you mentioned 1st Gen Taurus SHO but, showed a 2nd Gen one which is what I had in Black and Tan. Yamaha originally designed the engine with their 5-Valve Genesis head layout derived from their FZR750 and it was putting out around 300 HP. Ford didn't want that much power in a FWD so they detuned it with a 4-valve head. The motor could still rev to 8500 but, they rev limited it to 7300 to save accessories like alternator and A/C compressor. Sleeper cars have been around since at least the 60's but, probably even earlier than that.

this is super interesting and totally different. the rpf1’s look great on this car.. they look great on everything.

Love the videos man... you should see what we do with these engines in Australia... especially if you think this thing is fast 😉😁

The first platform I ever made power with... Got up to 480 wheel horsepower in a GTP and a 76 mm turbo and then the same turbo on a regal GS making 600 wheel horsepower but I couldn't keep bearings in it and eventually lost interest

Back in 07 I had a 98 Buick park avenue ultra. It had the 3.8 supercharged V6. The 3800 series II engine is one of my favorite engines.

I think the V6 and turbo gives it the odd sound. I remember my uncle having a cool Supercharged Rivera

Every single one of these cars of this design … pontiacs olds Buick chevys.. are well made solid cars so they start well on a solid base. Add performance mods and you’re on your way. And yes the Buick regal gs is my fovorite iteration of these cars followed by the Bonneville gts and gpz cars

That is a pretty sweet looking regal, plus it's pretty quick to top it off. I'd definitely drive that ride.

Oddly the chevy Trailblazers has tons of potential, 4.2 i6 holds mods really well. Toss on a turbo and some injectors a good tune close to 500whp. Absolutely nuts

David, you need to test out the '12-'17 Regal GS models! Had optional AWD and even a 6-speed available (FWD-only). '12-'13 came with the 2.0T LHU platform, then moved onto the LTG platform in the '14-'17. I have a '13 that is my daily and it is a fun car, and surprises a lot of people. 270hp/295tq, with a decent amount of aftermarket support.

Love it I have the 98 same color as yours with the supercharger and a smaller pulley and I can’t imagine swapping it for a turbo 😬🤤😮‍💨 LOVE THE VIDEO

This is the kind of builds I like the weirder and more unique the better lol

Respect that car. True hot rodding, stock engine, slap on a big power adder. Love it. I have a '13 ecoboost MKS, Grandpa car. $60k new, I bought it used $12k with 96k miles. Stock for now at almost 300whp around 13.7 1/4mile 4600lb car, but tuned soon!!

As a SHO owner (due to heavy influence from David's review), this is so fun. Also, anyone see the Terminator swapped Lincoln Town Car on CarsAndBids?

The Dragon is in my backyard(figuratively). Better than OEM brakes, suspension and most importantly, TIRES. I ran BF Goodrich most of the time and Pirelli a couple of times on a stock '94 v6 Camero with slight tweaks in the front end and kept in line with just about anything. I'm currently working on a '01 Vic. Brakes are done, nothing fancy, PowerStop kit. Replaced crap intake manifold, ngk plugs, accel coils(I liked the color), Monroes best shocks they had, new swaybar bushings, endlinks, upper and lower ball joints, tierods are next. Currently doing cloyes timing kit, Ford performance oil pump, "pursuit" water pump. Going to put some miles on her and stack up for a trans kit, rear end and Massive Traction system. Build stuff, have fun, be safe.

I've been waiting for this video. With a built motor you can have a daily driven eleven second car. The 3800 engine was very under rated.

The engine sounds different because it was originally designed as a v8, but they cut off the back two cylinders to make it a v6, so it has a different firing order and firing interval than other v6 engines that were originally designed to be a v6

🏁🏁Well would you look 👀 at this …cool build indeed 😎🤙🏾

I work at a Firestone, and someone brought in a Fiero with a sick swap- the supercharged 3.8 from one of these, it was a super cool and really clean swap

great build, any details on the transmission? what’s been done to it?

I grew up driving a 90 3.0 and a 93 3.8 Taurus, so the 1st and 2nd gen SHOs were always on my mind. Looking back now, I’d put the Marauder toward the top of my list but would also include the Turbocoupe, Mark VIII, and Mazdaspeed6.

Sounds like a Grand National

I use to have a lumina that use to be a police car and either somewhere down the line or for the police it got a supercharged 3.8 in it. The sound of that engine is really amazing for what it is.

I have always wanted one of the Rivieras with the L67 to build like this car! I would put a NA intake manifold on it and turbo it though, but the Eaton M90 can handle alot. I also had a 1990 Thunderbird SuperCoupe with the T5 trans and it was fast too.

I think that one of the biggest sleepers out there is the CTS V Sport. It is special in a sense that it is a twin turbo 3.6 litre V-6 that produces 420 hp and 430 tq. This is with 245 tires in the front and 275's in the rear. It has a Brembo brake package in the front and is on Bilstein springs. There are 4 modes with the most notable sport and track modes. However the list goes on and this is from the factory. Only 4404 V Sports we're produced from 2014-2019 and not many people knew about them but the ones who did. They have a performance machine that didn't have the aggressive looks of the CTS V but it would put moves out there in a straight line or on a track with corners which blew people's minds.

I own a 2014 Buick Regal GS as well. They've been under the radar for years. Great cars that no one looks twice at.

My grandma let me drive this car a few times to the store before she stopped driving and yes it was immaculate and solid good ride.

That tone difference you were hearing is because the 3800 series engines are 90 degree engines vs the 60 degree you hear on most newer v6's of today. I love these engines, bullet proof, and easily modded. I had a 1996 Buick Riviera L67 engine, and I miss it dearly. I wish I never would have sold it.. Had big plans for that car. Maybe I'll find an 8th gen Riviera again someday. Maybe sooner than later.. Also, Buicks throughout history have been good performance as well. One of the fastest muscle car during that era, was the 1970 Buick GSX 455 Stage 1. I'm 33 and I'd buy a Buick again in a heartbeat (first car was a 1969 Buick LeSabre 400.. another car I regret selling..). Comfy, quiet ride, and good styling to boot? Yes please...

It may not be the most powerful from factory but the 3800 has to be in the running for best V6 ever produced. The fact it weighs less than 25lbs more than the all aluminum 3.6L from an all iron engine is unfathomable!! I once ran the engine for over 10 miles with the temperature gauge pegged after blowing the garbage plastic coolant elbows, and the engine was absolutely fine after replacing the elbows!

I had a Gran Sport Regal and that car was so quick, comfortable and no one EVER expected my car to go so fast like it did.
