The ultimate sleeper
If you were to build up a realistic sleeper, what would you do? I'm not talking about buying the car, but building one up, that one wouldn't assume to be quick. I.E....buying a GNX and/or building up a GN/GNX.
Here's my thoughts, hopefully to turn in to a realistic project: 1. Start with a 1997 Olds Cutlass Supreme sedan 2. Remove crappy 3100 V6 and 4T60-E transmission 3. Remove front brake hardware 4. Remove all four wheels and tires 5. Obtain either a L67 (Supercharged GM 3800 V6) equipped donor car, or entire powerplant stuff, including engine, trans, axles, wiring...stuff like that 6. Rebuild the L67 motor with a better valvetrain, P&P heads, performance cam, computer, headers, smaller pulley, CAI, full exhaust 7. Build up the 4T65-E HD transmission to take more torque 8. Install cross drilled front rotors, and possibly four piston front calipers, use race pads 9. Install slotted rear rotors, and replace the crappy GM rear calipers with something else, use race pads 10. Install Mille Miglia HT-3 18x8 rims in Carbon Grey, along with 225/40-R18 Bridgestone Potenza S-O3 Pole Position tires 11. Install various but necessary engine monitoring guages to keep things in check. 12. Keep up with Corvettes on the dragstrip! This should be a $6000 or so project, yielding me a new motor, transmission, and other go fast goodies. The only outward cues will be the 18" wheels, and the upgraded brake hardware poking through. |
Call me strange but i wanna build up an 4door Aspen, that car would be the ultimate sleeper :D
|
I could see a built 360 in that car's future. Sounds like fun to me!
|
That Olds should be doable, the only thing I've heard is that at about 300 hp the trans gives up no matter what is done. Since the stock supercharged 3800 is 240 hp those mods would probably get you right to that point pretty quick.
|
No no. Ultimate sleeper is a beater 80's Volvo DL.
I've seen this done believe it or not. Car looked like total ass, but I noticed the guy had a rollbar on the inside as he burned past me. |
I have an 86 Olds Cutlass 4 door, already has a 307 V8 in it so the swap to a 406SB or 454BB may be done in a couple years behind the other projects. I don't think many would see the column shifted auto 4 door grandma car coming.
|
I want to get a 92-95 Taurus SHO and build it up, the motor will go 150 stock, until the computer cuts it off. souped up it would be awesome, because its a family car. Maybe the 96-99 SHO with the V8 would be better.
|
im with ya on the aspen... (i thought i was the only sicko)
only a 2 door, 440, 4 spd, Black primer. |
The V8 SHO sucked big time. And there is no aftermarket for it really. Stick with the Yamaha powered V6 SHO...much better engine, and aftermarket.
The 86 Cutlass sounds like it'd be some fun. Personally, I'd stick a 427BB in it! |
I want to do a the same thing to my cadillac since the factory 4.1L doesn't get good gas mileage and it only has about 140hp and is slow.. I was thinking when I got the cash put some baer brakes on it. And then put a 3.8 supercharged engine in. It would also making working on it a little more pleasant too.
|
mine is being cut up now...
1985 honda civic hatchback...... going in is SB chevy 350 with a front wheel drive olds tornado trans, the honda motor and trans are out and we are welding the the "new" sub frame up soon. spring snuck up on me and it is time to start heading to raceway park, englishtown nj to start bracket racing my 97 LT1 firechicken |
I thought the 86 Cutlass could be cool, just gonna depend on money i.e. how much we spend on the other cars first. Maybe a 454+ cubic inch engine with a centrifugal blower. No one would see the 700hp comin. hehe
|
My friend took a little 74 Fiat and stuffed a warmed over 350 in it, just looking at it you wouldn't think anything of it... just a wussy Fiat, but it had to have 100 pounds of lead in the trunk to get any sort of traction..... of course the throaty V8 dual exhaust kind of gave it away though :)
|
best sleeper I ever saw was a twin-engined Econoline panelvan. Thing had a V-10 running the front wheels and a V-10 running the rears. Both supercharged. . . .that sucker was FAST.
|
I have considered droppin an L67 Series II 3800 with an M90 Supercharger, plus finding the proper tranny and PCM/ECM/wiring. And putting it into my 1989 Bonneville SE...now, thats a sleeper.
|
that little V6 would be no match for many of the sleepers i've seen. 600-700hp in a clapped out beater with whitewalls :p
Big block Chevy in a mid 60's Rambler American 4 door, stock wheels and quiet exhaust. Restored Falcon with wire hubcaps, and huge power 5.0L disguised to look like the stock 260. Aspen? Howzabout an early 80's St Regis... 4 door, ex fuzz, 440 with N2O TR7 with 350, little 13" rims.;) |
How about a Volvo w/ a LS1 V8. I ran across a site that had conversion kits to turn POS diesel Volvos into kick azz V8 street sleepers. My roomate has a 88 Volvo Wagon that the engine just took a dump on him adn I am thinking about buyinh the car from him for like $500 then dropping a V8 under the hood and it would be one killer ride for under $6k
|
interesting idea.. go for it !! then post pics!
|
Yup, can't waitto see that one, try 0% financing, a lot less hassle.

The cool thing about turning a diesel into a sleeper is as long as you register it while it's running you never have to have it smog tested...... you can take a registered diesel and drop a killer drive train into it and never have to worry about aftermarket parts or stuff that wouldn't pass the visual inspection. You could go nuts and build a Rat motor for it and unless a cop looked under the hood you would get away with it...... :D |
I built a sleeper out of my last Suburban.
Suburban??? 1985 half ton, brown and tan. Yep. Yanked the motor and trans. Built a roller motor, flat top pistons, hotter cam, high flow oil pump. Trashed the exaust and had a custom dual exhaust built and installed along with high flow Dynamax mufflers. Used a Holley fuel injection kit, and of course a K&N air filter. Three angle valve job. Had the trans custom rebuilt and fine tuned the shift rpms. It would smoke the tires with just me in it. I just loved taking smart assed folks at stop lights. Passing on the interstate was a breeze. Hated to give it up but on to better and bigger things. |
nothing too strange about a sleeper suburban. Liegenfelter made one in the late 90's that was fast as hell. Car and Driver did a nice write up on it.
|
maxima
choose if you want an auto or manual put some sticky tires on it cheap route: InJen Intake Y-pipe B-pipe (not so big) UDP nitrous =12second car fun route: T04B Turbo Spearco FMIC Management Electronics UDP =xx second car depending on boost. yeah, ive forgotten some things, but the you would be running on a stock engine with minor modifications to the engine. |
A friend of mine is planning to drop a Spoon twin turbo into an Odyssey, replace the axles and tranny, and throw on a NOS fogger system. He thinks it's a great idea, I'll believe it when I see it.

Has any seen the Dogde Omni that has the turbo? I forget what it's called exactly. Some kid I knew had on all done up. I had one look at it and said that's not much to look at. Then he had shown me what was hiding under the H@@D! Yikes! Then he ask me if I would like to go for a ride. That was the badest Omni ride I ever had!!!! Later he had told me all of the MODS that had been done. He had to have special half shafts made because he was breaking them on the track.....what a great ride, it didn't look like much, but it flew. He was very easily eating up the 5.0 stangs, he had a harder time with the BBlocks........Just thought I'd share my story!

my friends 180SX was beaten buy a Daihatsu (Its a cheapo korean car brand) charade with a new turboed engine of somesort

78 Caddy with a 502 and some street carver suspension is my ultimate ride, coming soon to a boulevard near you

My favourite sleeper was a buddy's satilitte sedan. Had a worked over 413 pushing a 3.90 rear thru a 4sp. Had better than 400hp at the rear wheels and would take just about anything on the street while still looking like something grandma drove. |
You guys wanna see a sleeper, THIS IS A SLEEPER.

If you try to race someone with a car that looks like a POS, they'll know you've got a sleeper. What do you think about a Syclone with a Busch series aluminum V-6. With proper accessories, it'll run low 10's w/out nitrous.

I just e-mailed the guys at Dream Car Garage about a car featured briefly in one of their segments. A Plymouth Reliant that had been converted to RWD with a 440 in it...
|
A couple that I've seen that have impressed me are the people with the turbo dodge caravans and the k-cars. Many of them are running in the 12s.
Also seen a few late 70s volkswagen buses running the porsche 3.0s. Those are about as unaerodynamic as it gets. And they haul with the 3.0 in them. It's also not a real difficult swap. |
Just so you guys know, Tom Hnatiw from DCG sent me back an e-mail. The Plymouth Reliant with the fuel injected 440 does exist, and belongs to Jason Roberts, who is shop manager for Legendary Motorcar.
|
a buddy dropped a 350 chevy engine in a b2000. This truck was a serious sleeper cause the guy left it all primer spotted and had good tires on stock wheels. Had to talk him out of the stacks for his exhaust though cause that was going too far.
|
Hell no, stacks and flappers are the way to go.
|
I read a while back about a guy who took 80's vw bug, pulled the body and the engine out, cut the rear last hal of the frame off and welded on the front end (chasis and engine only) of a '72 cadiliac eldorado. He worked a scoop to go down through the floor to feed the air intake and cool the radiatior. Built a box around the engine, which took up all of the back seat, covered it with carpet. Now think of it You have a Bug that looks stock except for the funny looking speaker box in the back, but when you floor it you have all of the might of a 367 GHP 8.1 liter engine behind you. That is one hell of a power to weight raito. I thought it was nifty.

Have to get a look at that episode I just happen to have a dodge big block and a 85 new yorker sitting around. |
best sleeper i have ever seen was a Geo Metro Hatchback. white faded paint, 13" pizza wheels, the whole POS car thing. However under the hood was a 13B TII engine out of a 88 AE Rx-7. kinda of scary to see a metro pass you at 120mph.

I like my friends turbo G20. 13 second 4 door.

My Lincoln Mark VIII has excellent sleeper qualities. It looks like your typical car that grandma would drive to church, and alas it's typically used that way. But has a 280hp V8 that's basically the same engine that went on to be used in the Mustang Cobra. Runs very low 15's in the 1/4 mile. Not insanely fast, but enough to surprise the hell out of a lot of people.
My slightly modified '88 Thunderbird Turbo Coupe is a good sleeper too. I pissed off my boss when I outran his brand new Navigator with my old POS 4-banger. He just drove by with his middle finger in the air and never brought it up again. :D matteo101, I emailed those pictures to a couple friends of mine. One loves Cadillacs, the other is a VW fanatic. They both got a kick out of it. Is there any info available with the details of the swap? The pics are cool but I'd like to read about what was involved. |
Quote:
ok ya that sounds a little more like it! |
I actually just finished my sleeper project. I got excited whe i saw this topic.
I started off with a 91' 240 volvo. It had 200,000 on the motor and was about beat. Picked it up for $150 and no rust on the car (unheard of for upstate NY) So i buy a little kit from converse engineering. Its all the necessary bits for a mustang 5.0 swap. I bought a 87 5.0 HO donor car. I took the engine down to the block and rebuilt it with new cylinders, rings, lifters, valves, had the intake/exhaust ported, got a new head and Bought a vortech supercharger for it. Tossed it into the 240, got a custom drive shaft and use a 8'' ford rear end. I run 6 lbs of boost and run about a 11.4 at the 1/4 Its a head turner, I get kicks out of spanking up on kids in their little 4 bangers and even taking out other american muscle. The looks on peoples faces are priceless. |
Mind if I ask how you got that 8.8 rear in there? More or less in terms of how your control arms are setup up.

WOW? you got pics of that...love to see!:D |

There was a POS Dodge Omni (turbo) here in town that pulled the pants off an '03 Viper at our local track last year. Funniest thing I've ever seen. And street legal. It was one of the ugly Omnis that looked kind of like an old VW rabbit.

Turbo omnis were available from 84-87. Some '87s featured a hybrid stage I/II kit that produced 187hp. Not bad in a car with a 2300 lb curb weight.

There were no 97 cutlass supreme 4 doors that used the "crappy 3100" V6 engine, no 4t60-e transaxle as all 97 cutlass were still rear wheel drive. None came with rear disk brakes and although it is possible to convert to disk brakes that is not going to make the 87 sedan a front driver. If you started with a 90 model you could do these mods and be on your way. I have an 88 base supreme 2 door that I sold new in 88 and bought back from the owner and it is about as base as the got that year. It came stock with a 2.8, auto overdrive, "am" radio, crank windows, pie plate wheel covers on 14" wheels, column shift, P-steering, P-brakes and no air conditioner, etc. Now this is going to be a sleeper with a built-up L67, 4t65e-hd, quick ratio steering, later 11.25" front rotors, replacement rear disks and calipers, upgrade pads and struts, HD radiator, headers and exhaust from borla with intake from K and N cone infront of the rad, 16" stock "International" wheels and tires. In that way it will appear "stock" until the performance is shown by the sound of the pipes as it accelerates away from the unsuspecting "victim". In 1988 I was selling these cars and the car in question was one of the first ones that we got in at the dealership that 1st year of the new front-drivers. In my case the on the road cost shoud not exceed $4500. Hope this bit of info helps you in your quest to build a "sleeper cutlass supreme". By the way my car has only 7500 miles on it and is mostly still original-as-delivered. |
uhmmmm...He said 97 cutlass supreme. not 87. the 97 cutlass supreme is front wheel drive, and has the 3.1 V6
Long story short, you typed alot for nothing, sebring |
Well, it's two years later, the engine is in the garage still, but kinda cleaned up, and maintanence stuff is done. I'm not going to undertake the swap myself, but rather have it done, as I just don't have the tools or time necessary to do it. It's getting done in May, and he's gonna take pics for me. I'll post some up as things progress. Not going to modify the engine much this time around. Going to install a 3.5" pulley on the blower, and call it good.

1990 Crown Vic LX can probably find one of these for like a grand easily.
Yank the stock 302 drop an EFI 351 Windsor in the sucker that's been stroked out to 419 cubes toss in a forged crank,connecting rods,forged dished low compression pistons. Trickflow heads with a nice port and polish. Trickflow intake. Yank the stock rear end bolt up an 8.8 inch rear with 31 spline Moser axles. 3:55 gears. Performance C6 tranny 2500 RPM stall convertor. Then turbo the sucker put down like 650 horsepower on daily driven boost. Redo the interior with new carpet, new head liner. New trim pieces. Toss in some new speakers a modern head unit. Lower it a bit get some old school steelies and some big tires paint the whole shooting match flat black. Nobody would expect that old black Crown Vic that is bumping music so loudly would have enough power under the hood to burn all but the top contenders. That is until the tunes got turned down the cut outs got opened up and rattled their windows something horrible that is. The more I think about the idea the more I want to try it. That would be SO much fun. You don't see too many people hooking up old late 80s early 90s Vics. I see people doing that same combo to Mustangs, Cougars,Thunderbirds hell even old trucks. But nobody every suspects that old Crown Vic. |

All of the aftermarket that you'd need for your v6/v8 SHO. Both the V6 and the V8 were Yamaha, though I've never figured out why the V8 blew as much as it did. |
I have been taking an intro mechanics class at the local community college. One of the mechanics there has a mid-eighties cutlass supreme with an LT-1 engine and I believe an early nineties trans am rear end. It does have a torsen differential, which he showed us when it was on the lift. I think (don't quote me) he said that with the 2.7 rear end gears it ran around low 14's.

As a sleeper, I was also remembering that car that took part in the SCC Ultimate Street Car Challenge a year or two ago; it was a Hyundai 4 door sedan with an engine on both ends of the car, each engine driving the respective F/R wheels, moded to run on pure methanol; the guy only street races for money (my public safety comment delayed) and the thing is insanely fast, at least in the first 1/2 mile. |

1990 Ford Taurus SHO Stock engine: Yamaha 3.0L V6 DOHC 24V FI Engine Stock HP: 220 Problems: bad tranny, cooling system failing, other undiagnosed engine problems bet: My buddy with a Mustang GT said that no matter what I did to my car, he could beat me. I had money and I was young. I started by contacting several good mechanics locally who were into building unorthodox cars. One of them agreed to let me assist him, for a price. He had a 1968 Firebird 400" engine with part of the frame. We rediesigned the SHO's frame to match it with the stronger, heavier Potiac frame. Had a hell of a time with the bumper. We decided to counterbalance the heavy engine with a beefier exhauset, roghtly 3" straight pipes coming from stainless 4-1 headers. The steering and suspension had to also be adjusted for the weight. I'll let you know if I find pictures. Just kidding of course. Who would put a V8 in a taurus? :crazy: |
Ford would. And did. It was a 3.4 Liter DOHC 4v V8, made 235HP if I remember right.
|
Damn, DEI37 beat me to it. Plus the Lincoln Continental is on the same platform as the Taurus, and has a DOHC 4.6 V8 putting out 260HP. It's detuned somewhat (puts out 280-300hp in other applications), most likely for torque steer and/or transaxle durability issues.
Now there's an idea--take a late 90's Taurus wagon, drop in a Continental drivetrain, beef up the tranny, and get the engine back up to the power output it has in other cars (intake/exhaust/chip most likely)..that'd be a heck of a sleeper! |
hmm a good street sleeper.
Id go with a honda accord 4dr, back 1/2 it and fit some 275/50 street slicks on it. put reg 255/50's on the front the mod the front suspension to hold a 434 sbc. Who'd expect it. with some loud pipes and a bunch of decals everyone would think just another kid in a hopped up honda. Or just leave it in primer ;) |
lol nobody would mistake the can of angry bees that would usually come out of such a car for the low grumble of a SBC. You'd be seen coming a mile away. :)

a near sleeper I drove (not mine) was a early '60s Austin Healey Sprite ( the bug eyed one) with a 327 chevy, 2 4 barrel holleys 3/4 race cam, rollers, custom headers, 4 speed trans, cut down positrack rear end. the only thing that gave it away were the carbs on the hood, and with a cover they were not obvious( unless you knew what a sprite should look like) the big problem with it was it shredded the right rear tire all the time ( torque would lift the left side of the car, not off the ground but enough)
and before someone asks I don't know how he got it in there, speculate ( well am certain) custom mounts and reworked body. If I remember right it would run in the neighborhood of 12 second quarters. I saw and drove this in the early '70s once,left the country before I could find more out about it. |
on another note, get a late 50s nash rambler, drop in as many cubes as you can replaceing all running gear at the same time. you'd have a big heavy UGLY but fast car
|
I think it's in this month's HotRod magazine ...Jay Leno's "sleeper" Olds Toronado with a Lingenfelter twin turbo big block ...I think it was a bb not sb. Of course most of us don't have unlimited resources like he does but I thought it was cool anyway.

If you're interested in more:
http://www.seriouswheels.com/top-196...o-Jay-Leno.htm my edit: and I believe it is based on a small block |
My fave sleeper was the 11 sec Escort. 5L Mustang engine, miata tranny with RWD conversion.
What makes the Cutlass ideal for this??? I have a '96. BTW, I thought you could get a special ed. of the car that had an L67 of the floor. |
Cutlass rwd Conversion
I gave this some thought a while back. The w-body is not engineered for rwd, therefore the rear suspension is not very strong and as with most fwd cars there is not much of tranny tunnel. I've come up with a couple of ideas found surfing the net. These would give more room in the engine bay and better weight distribution.
1) Use a curved "rope drive" torque tube and rear transaxle from a 63 Pontiac Tempest like Jay did on his v-12 Corvair. See it at www.corvaircorsa.com/V-12-01.html . Very cool conversion. Don't know how I would hang the transaxle and suspension though. 2) Torque tube with manual transaxle and torsion tube suspension from a 944/928 Porsche. As with the 928, the 944 transaxle can also handle the power and torque of a v8. Found info at renegadehybrids.com they do v8 Porsche conversions. The only thing stopping me from persuing this is time and money. :( |
Back in 1987 a friend of mine wrecked a 71 challenger with a 383. We took the motor trans and rear end and stuffed it in a plymouth reliant K station wagon. We were young and stupid. We had no idea that you had to beef up the unibody to support the power. It only took 4 weeks to destroy it to the point it actually broke in half. We had jumped the car a few times prior to the engine swap so maybe it wasn't the best car to put the motor in but it was fun and faster than anything I have driven since. I wouldn't drive it that fast if I had the chance to now. Like I said we were young and dumb. It was one hell of a sleeper. The best part is that we were seen in the original car prior to the swap and it had crappy exhaust so no one thought twice until we stomped the gas.
