Project Super Sleeper

Okay well I'm starting to look for a new car and i've decided to go with a super sleeper that i plan on modding the hell out of....i want one of those cars that you just look at and shrug off and then when they go WOT, you're confused on how a family sedan could go that fast...i'm not planning on spending more than 15k on the car....and i've narrowed it down to these:

1. 2000 Pontiac GTP (i would debadge this and take off any spoilers etc....make it look like a regular grand prix)
2. 1999 Taurus SHO (same as GTP...make it look like a regular taurus)
3. 1998 Buick Riviera (this would probably be the best sleeper...but the heaviest)
4. 2000 ish Nissan Maxima

ANY OTHER SUGGESTIONS OF THESE TYPES OF CARS WOULD BE APPRECIATED :icon16:

The GTP is your best bet for cheap speed, but a lot of people will figure out that it's a GTP, so the surprise factor isn't as good. I don't like the newer SHOs at all, and the V8 has some reliability issues. The aftermarket isn't really there, either. If you get an SHO, go for an older one, with the 3.0-liter V6. The Maxima can be made pretty fast, but it's not a good choice for a sleeper. Most people already think the Maxima is pretty fast.

I think the Riviera is your best choice overall. The supercharged 3.8L has plenty of cheap aftermarket, and most people don't even know what a Riviera is, let alone that it's actually pretty quick.

Instead of a GTP or Riviera you might look at a Regal GS with the 3.8 s/c. Basically the same car as the GTP, but with the Buick badge few will see it coming.

Also stay away from V8 SHOs! The V6s are faster and far more reliable, the V8s are notorious for cam problems that generally end in engine failure and VERY expensive repairs. The only way you should even consider on is to make sure the owner had the cams welded, and they have proof verifying that the work has been done.

Get a Toyota Cressida is RWD and just drop either a 1JZ or a 2JZ into that sucker

Here's a hooked up one but you want one more low key than that obviously for a sleeper.

1995 Toyota Supra Turbo.....

1995 Toyota Supra Turbo.....
:screwy: yeah, and on that note...the ultimate sleeper would have to be a Ferrari F40. :lol:


anyways, i would go with anything that has the 3800 S/C...reliable motor, reliable car, etc.

Even the GTP, very few would expect it to keep up with their sports car or what have you. I have a 2000 GTP and people are surprised when they are 8 cars behind before we hit 50mph. They expect it to have a little pep but not quite as fast as it is. Plus even though alot of cars have the same motor...performance parts are offered at large for the GTP and its set-up (ie: exhaust).

Anyways, I have intake and a custom cat-back with flowmasters and I ran a 14.3 at the track. so very quick for what you pay for.

hmmm it looks like the S/C 3800s respond pretty well to mods...and being as K3 is already running low 14s with some pretty simple mods it seems like that would be my best bet....i also was wondering if i could possible put nissan 300zx performance parts on a 2000 ish maxima.....they're the same size engine i believe...so maybe?...and also i was wondering what kind of work is put in if you maybe switch the pulley on a GTP to say...a 10lb pulley....and what kind of horsepower that would be putting out....thanks for the replys

I second that!!!

i will be going down to a 3.4" pulley and a reprogrammed PCM in a couple of months. maybe do a little more exhaust. that should net me mid 13's from what other people have told me. thats about as far s i would go...but i do know you can get down to mid 12's with only minor bolt-on's. so yes, the modaibility is superb IMO.

supposedly, your not supposed to go down to a 3.25" pulley until you have some other stuff done but i know people running an intake and 3.25" pulley without a gliche.

are smaller pulleys an easy install? and what stuff would i need to have done before running a 3.25" pulley.....like upgraded internals?

noone will suspect you :smooch:

they are easy to install but they recommend you use this pulley puller that you can rent from most 3800 performance places for like $30 or so. between me and you...you dont really have to use that.

anyways, no you dont need to upgrade the internals to do a 3.25" pulley. most people will recommend you get an intercooler before you do it but i would definitely get a 160 degree thermostat, PCM, intake, and exhaust work before i went down to a 3.25". i dont really think an intercooler is needed but it would help a ton i hear.

i personally am only going to a 3.4" pulley mainly because i have another performance car and i just want a little more pep in my daily driver.

I've seen a turbo'd Maxima beat up an EVO.... I think it was a Garrett Turbo installed.. I could see if I could find more info if you want.. That thing was insanely fast, and I if I am not mistaken Maxima's stock already are quicker than the GTP's?

^considering that a maxima makes more hp N/A than the s/c 3800 does and weighs 200-300 lbs less the max is probably faster stock, not to mention you can get the maxima's with a manual tranny, but mod for mod the GTP/Buick's gonna respond better considering that it's already got FI. i think either car would be a good choice, if you can swing it, look into a 02-03 maxima with the VQ35, it's good for mid-high 14's stock.

look into a 02-03 maxima with the VQ35, it's good for mid-high 14's stock.

well thats what the GTP runs despite the 200-300lb weight advantage and whatever else.

you have to remember that the maxima may make more HP but the GTP has 280 ft/lbs of torque pulling its weight at 800 less RPM while the maxima has 246 4400 RPMs. this could make a big difference in straight line performance. plus the 3800 S/C is known for be quite a bit underrated from the factory.

reguardless, both would be good choices but liked mentioned earlier. the 2800 SC would make a better performer if plans are to be modified.

i also was wondering if i could possible put nissan 300zx performance parts on a 2000 ish maxima.....they're the same size engine i believe...so maybe?...

No, that won't work. The 300ZX used a different engine than the Maxima. Even if they did, some parts might not work because of the rwd vs fwd engine orientation.

If you picked up a 2002-2003 Maxima, some 350Z parts might work for you. The 2002-up Altima might have some parts that would fit too.

I beleive a guy on Maxima.org using slicks and a 100-shot broke into the 12s with his 2002 Maxima.

Hello McFly, NOT A SLEEPER!

It never ceases to amaze me how many people visit these forums and have no clue what a sleeper is.

lol.....and he's not a noob....for shame...j/k:D

lol.....and he's not a noob....for shame...j/k:D

so i see you ended up with a GTP 4-door in red. very nice...do you like her so far? what is gonna come first?

okay well i'm thinking about looking for a full exhaust first.....it doesn't matter how much your car inhales if it can't exhale right? and then after that i'll try looking for a PCM....i really wish they had these in manual but meh with the PCM it should have good shift points....

As for how the car is....i love the supercharger whine...i think i'm addicted to it....you can barely hear it at WOT but it's still hella cool...and compared to my stock Z34 this thing is a beast....i took it around some corners and it's so much faster out of them.....i'll do some update threads every once in a while but winter is coming so i don't think i'll be doing too much....but it'll be a great project car nonetheless....and i hope that i can raise the govorner above the 107 mph it is set at.....i ran it last night on the highway against my buddies grand am and i got up to 107 and it felt like i slammed on the brakes real quick and i looked down and i was only at like 3500rpms...i could go so much faster...lol....but i slaughtered his grand am gt coupe...so i'm happy so far... :biggrin:

Well along those lines I think it's good to get the intake, headers, and exhaust all at once so it breathes together in unision...if you cant do headers now, then just intake and exhaust...then add the headers and get a chip/ECU reflash or whatever GM does.

Had I seen the post earlier I would have recommended the GTP... yeah I/H/E with a chip is a good start...you should also look at how maxed out the supercharger is and the possibility of an upgrade...those Series III engines can handle alot of boost on stock internals

and remember, DEFINATELY talk to Jeffsgtpsleeper...I haven't seen him on the racing forum lately but hes definately the man to talk to...him and is 12s GTP (mabe 11s I dont remember)

107mph? no supercharger whine at WOT?

first, what year is yours? reason being, i have a 2000 GTP and cuts off at about 130mph. i cant really tell because the speedometer stops at 115 but buries well past the end of the speedo.

second, do you have an intake? i could barely hear my supercharger whine at all until i got an intake. now it screams from 3000-6000rpms...i hosted a video on streetfire.net but i dont think it loaded yet. i will give you a link to it once i figure out what happened to it.

anyways. sounds like your on a good start...i dont think you will be dissappointed.

oh heck yeah i already sent him a PM that had some questions in it....i think that the intake will be my first mod and then i'm going to look at PCM to take advantage of that extra air....then i should hear that REEEE! And just as an update on his GTP he's running 11.9 @ 114....lol....that's crazy :iceslolan

i have a 1997, basically the first year of the supercharged GTPs....i had a friend that has a sunfire GT and his is governed at exactly 107 too, i think it's kind of a pontiac thing... :loser:

weird...i wonder why they hired the cut off by 2000. like you said, at 107 your still way down in the RPM range. at ~130mph i think im at about 5500rpms, i will have to check next time.

the supercharger whine with just an intake is surprisingly loud with the stock pulley. it is definitely an addicting sound...

I ordered a Wiz Air intake today, the best one i could get....Jeff uses it on his GTP so i figured that it's got to be good and i'm going order a full exhaust next week......i'm trying to get all the mods i can before winter...then i'll have to switch to my winter beater (Z34)....i can't wait to hear that superchager scream... :iceslolan

Hello McFly, NOT A SLEEPER!

It never ceases to amaze me how many people visit these forums and have no clue what a sleeper is.

wtf.. hows it not a sleeper.. it doesnt look fast to me, and it doesnt draw that much attention... nothing most people would look at twice, since most people dont even know what an alltrac is\

we are talking about america right?

you seriously think that the adverage person or cop looking at this

http://www.gtfour.ca/DSC01977-1.JPG

would think it would be fast?

now that i look at it again.. your right, i think it looks like a supercar... kinda has an enzo feel :rolleyes:

The point of a sleeper is not to catch random bystanders off-guard, it's to catch other racers off-guard. Most racers have heard of the Celica GT-Four, and know that it's pretty fast.

Stock internals...thats what really gets to me about his 11s Grand Prix, that its reaching those time on stock internals...and yeah hes sleeper is crazy fast...wish I couls see his sig to remember what mods he made

and Kman nice Subaru...whatever happened to modifying the hell out of your Camry??? ph and a word of advice, don't try to put a HKS 3' Sti exhaust on the RS...it doesnt fit...theres alot of aftermarket Subaru stuff thats not compatible with the RS

The point of a sleeper is not to catch random bystanders off-guard, it's to catch other racers off-guard. Most racers have heard of the Celica GT-Four, and know that it's pretty fast.

the "turbo" and "GT-Four" decals don't help either. people will know it is not your average celica and like kman says...racers and tuners know what it is.

the GTP, racers knows its supercharged but they still don't think it is fast. its a big family sedan made by GM, it cant be a 14 second car, but it is.

I decided not to modify the hell out of my Camry because it was an automatic, and tranny swapping in that car would have been a pain in the ass. Plus the fact that it was just so old and beat-up. And no, I'm not going to touch my Subaru's horsepower at all; all of my aftermarket work is going into wheels, tires, and suspension.

buy a geo metro and put in a v8

Check out the Dodge Intrepid. Nice powerful V6 with mopar aftermarket support. Styling is Unique to put it lightly, but definetly has the suprise factor of a sleeper.

ohhhh right on the 1 month mark of the last post...you cut it close Ace valdez...but a word of advice, don't open threadd older than a month, a mod will lock it up and yell at you

and hes going with the GTP I believe...and Kman just curious what exactly was your grand design for the camry?
