hello, I've got a 93 deville (4.9L), was wondering if there was a NOS kit available for this car?

1) don't put NOS on the Caddy
2) I have heard of people with a stock 4.9 putting a 100shot on and being fine IF THE KITS ARE PROPERLY INSTALLED
3) don't put NOS on a Caddy
4) I was actually looking into the NOS Sneaky Pete system..... I gave the idea up, bu it is very very simple to install, easy to hide, you don't see anything etc.... it is I believe a 35shot, and any engine in good tune could handle that with no problem
5) NOS + stock Cadillac DeVille = no

why do you say no to it? Nitrous Express has a nice wet set up that you can use on the 4.x PFI engines. And its ajustable up to like 100hp.

100 shot eh ? itd be cheaper for me to go out with the shot gun and shoot the tranny .......

a stock 4t65e isnt capable of handleing a car making 285 hp and over 300lb feet and weighing 4000+ lbs

now if there was a way to mate a 4t80e to the 4.9 then maybe , but then your spending way to much money on a car whose whole purpose in life was to transport the elderly untill they got a ride in the back of the meat wagon or herse

if i was to place nawzzz on a caddy itd be a 93-96 fleetwood

actually the trannys in the '91-'93 DeVilles are the 4T60E.....

the engine stock is 200hp and 275ft lbs of tourqe.....

.... I just don't like NAAAAWWWWWZZZZZ I would only use it if I had a car with a performance engine...performance as in all built up and only use it on the track etc....

NOS is very common on 4.5L caddy engines in fieros using a completely stock engine with mild ignition and fuel system upgrades. I'm not sure, however, what it would do to your tranny, considdering the caddy weights twice as much, and the fiero's 3-spd is already a stronger trans. If you do add NOS to a caddy, go with a 50 to 75 shot max, and upgrade both your ignition and fuel system. Never use it at low RPM, regardless of throttle position. Your engine makes way too much torque for your tranny to survive a 75 shot at low rpm. By low RPM, I mean under 4000.

under 4000rpm? the 4.9 redlines at 5250, and when I was testing it, most WOT shifts were around 4900rpm, and only once I got it to shift at 5100rpm.... but by that itme it is loosing power.....

I agree about the tourqe thing.... 275ft lbs of tourqe at 3000rpm, you start injecting N20 and you'll kill the tranny....

.... I owuldn't say that the 3spd auto on the Fiero is more strong then the 4T60E though.... the biggest engine to be mated with that was the 2.8 V6.... 150hp and 175ft lbs of tourqe (my father has an '88 Formula)

On thing to remember about comparing the 4.5 engine and drivetrain in a Cadillac to that of a Fiero is that the Fiero is a much lighter car. Damaging the powertrain isn't a function of how much torque the engine can put through the trans, but rather how much actually makes it to the ground to react against. The force (torque) required to move the vehicle is proportional to the vehicle's mass and the amount of engine torque that actually makes it to the ground is dependent on the friction of the tires against the pavement, which is also dependent (all things being equal) on the weight over those wheels.

With a light car like the Fiero, the fact that you'll be able to easily spin the tires acts as a "safety valve", if you will, preventing all the torque from actually working against the drivetrain and minimizing the chance of breaking something.

Putting the same, more powerful engine and trans in a FWD Cadillac, and you're going to be able to get much more torque to the wheels and need much more to actually move that vehicle, greatly increasing the torque that the drivetrain actually experiences and thus greatly increasing the chance of breaking something.

Just something to think about...

how does it hook up to the fuel system. do you plumb individual injectors into the intake manifold or just stick a tube into the TB? how much.... never mind, how bout posting a link!

DON'T DO IT! Nitrous is terror to an engine, especially one not made for high HP or Torque. Buy a Camaro, Trans Am, Vette, Even a Mustang, but why mod a Cadillac???

you again.... maybe it's challenging to us to fab parts to make cool go fast. i bet it brings alot more satisfaction that just bolting on the same crap everyone else does. i'm proud to have something unique!

I'm glad everyone has a right to express their opinion, but for goodness sake, it's a pushrod performance and technical info forum... i can understand if you'd say that if we were at your camaro forum. please don't hate, that all i'm saying! :)

btw i didn't say any of this in my angry voice... :rolleyes2

How would you like me going to your Camaro forum and telling everyone to stop modding their cars beauce they will be like everyone else, and to buy a Cadillac and mod that to be unique.... really, stop now.... what is the purpose to that post? is everyone honestly gonna stop, rethink what they are doing and not mod their Cad just because you told them to?

My intent isn't to get you guys to stop modding you Caddy's. My intent was to get insight as to why you want to do it to a car not made for going fast or being modded. Also, my other intent was to inform you guys that unless you're going to do Thousands and Thousands of dollars worth of work little stuff like Plugs, wires, chips, and flowmasters are not going to do anything except waste your money. You don't believe me? Try it and tell me what you gained at the track. Better yet dyno your car before and after and show me the graphs. It's a lot of money to do these things, and if you can't afford a $10,000 Camaro how are you going to afford $10,000 + worth of engine work to even get into the 14's or 13's? Also, to get enough power to even get into the low 14's or 13's how are you going to transfer the power? You going to put slicks on a front drive car? What kind of suspension mods to help hook up? I have lower control arms, lower control arm relocators, adjustable pan-hard rod, hal 12 way adjustable shocks, adjustable torque arm, and poly bushings throughout, also have P315 35R17 Nitto drag radials all in the name of traction! Not to mention a car that already has the geometry set up for greater traction than a front drive caddy.

you want us to feel badly b/c we don't have 10,000 to blow on a car?

you want us to tell you how cool your camaro is and that we are going to trash our caddys and get a camaro just like you, with all the cool stuff you have?

you just don't get it, do you?

btw how old are you? you sure do act young. will you please share some pics of you super cool camaro with us? i don't even think you have one...

In case you didn't already read what cars I have, I have a 90 Cadillac Eldorado as my daily driver and a 99 Z28 as my fun car! My Caddy is why I'm even on this message board. It just struck me funny to see you guys talking about putting flowmasters and chips on your caddy's thinking you're going to gain some great HP. It's not going to happen.

Enclosed are 3 pics, 1 of my Camaro, 1 of my Caddy and 1 of both cars. Also, I am 22 years old, 23 in May!

Later Guys!

nice cadillac man! there's something we can agree on, right?! i'm done arguing about it, this is obviously going nowhere! :rolleyes: i hope we can all just be friends! :bouncy:

The reason why I would never use nos (yes i know this isnt related to the subject but good info)...

1. Something is un-satisfying about 30 seconds of fun

2. It costs a butt load of money after that 30 seconds to get fresh No2

3. Can be a pain to install and is dangerious on stock and yet, even high end motors... your better off with a turbo or supercharger.


If you do NOS on a Cadillac... there better be a good reason, it better be able to handle it or no more caddy and in the end it costs more than a turbo or supercharger because of all the refills you'll need if your an avid user.

Thanks man! Yes we can all be friends!!!

Since this is a Caddy message board I'll give a little info on my Caddy. It's a 90 with 70,000 miles on it. I bought it 2 years ago, April of 01, with 24,000 miles on it. I drive a lot!!! It's in mint condition, not one dent or scratch. Runs great, etc. I did have to replace the alternator like 3 times, and I needed new injectors, but other than that it's been good to me.

I agree, nice Eldo. You also make a lot of valid points. I split the 4.9 performance thread, and sent it to the Non-model specific. Feel free to continue there. BTW, :welcome:

I made a mistake in my post about my Eldorado. I said I bought it in April of 01, I meant April of 02. Also, the other pictures that I uploaded are really bad quality, I tried making the files really small so they would be able to be uploaded but I ended up making them too small. I re-saved them, making them a little bigger, so the pictures aren't all boxy now. These should look good.
