Just curious, what model is it?

Arn

Thats kind of funny because everyone that talks about final $$ numbers is always saying around $2500. I have seen more then one person post this as well. This doesnt' seem like so little money to me in comparison. And also my old 85 GT auto with a 50 shot was turning mid 14's at 90 mph. That was on a 50 shot but ran a 70 shot most of the time to get me into the low 14's. I haev seen 4.9's with the auto trannys hit 90 mph trap speeds too. So how can a 85 gt with nothing but a 50 shot of nitrous not hang with a 4.9 from a roll when we have the exact same trap speeds? To me that means it would be dead even all the way to 90 mph.

And black azz gt, why dont' you tell us what your 7 bolt ons are? I mean real bolt ons made by aftermarket companies for the 4.9. Not generic speed parts from Summit. Noone has yet to be able to answer my question as to name just 4 aftermarket bolt on parts for the 4.9.

Here is the thing. I posted that you can put in a completely new GM 2.8 AND nitrous all for under $900. I however got flamed real good for it from the nonbelievers. Its kind of funny cause some of the people were 4.9 owners but of course not all of them were. So you can do a new 2.8 for less then $1500. You dont' have to add headers, and you dont' have to add intake work. Just install a new fresh engine. My new fresh engine will be less the $500. Also you dont' need to rebuild an engine to handle nitrous although you can. As long as the compression is good in all cylinders its just like adding a turbo.

I am sure if I had a turbo I wouldnt' be getting this much flack. If I had a 2.8 with a turbo I prob wouldnt' be getting so much hate but because its nitrous and not full time power, there is this big stigma that the hp gains aren't real and blah blah blah.

NY Fiero: nice retort from you as always. But my offer still stands. Bring your 4.9 swap down here when its done and you can buy a round of victory beers for me and my mates. Daytona show would be a perfect excuse to bring it here. And yea the n star was made to drive old people around but come on man its a totally different engine. 300 hp 4 cams, huge powerband and great top end. Lots of aftermarket for it. The 4.6 n star was a detuned race engine that GM threw into a caddy and had to limit the hp so as it not to be faster then a corvette or on par with one. Think about it. A nstar can fit in grand prixs. But they arent' doing that till now, and now that gm is doing it, they are detuning the motor AGAIN! Down to 275 from the 320 that they make in the caddies now. I mean the 300 hp n star was able to get a 4500 lb caddy to 60 in 6.7 seconds. If you rolled up next to one of those in most sport compact cars you would lose!! Also the n star has more top end pull then a nissan 350Z. This has been proven by JM on his way to Miami in a rented Caddy.

And Arns thats the carb that he swapped onto his 4.9

Edit: Oh yea I haev been reviewing dyno charts of the 4.9 and my 2.8 on nitrous beats them all from this website here http://www.etrackmasters.com/dynocharts.htm#Pont Now throw in the 2.97 gears or whatever it is in teh auto tranny and you will see that it wont' have much for top end. Torque wins from a light. HP wins from a roll. From a roll I have more hp and I have better gearing. Do the math people

I gotta have more cowbell!!!

I hope your boss knows that your on the net all day long...
BTW Being an IT director...( IOS cert MCSA cert RHCE cert)
maybe I'll tell your IT guy how to firewall you out of this forum.
This is my last post on this thread
I may not even do a 4.9 ...
I may do an archie kit.... but I can RESPECT a built or stock 2.5, 2.8, 4.5, 4.9, 305, 350, N*...
Go back to work.

My seven mods are not 4.9 specific. Still mods though. Your NOS kit is not fiero specific either.
the same.
This $900 shite is stupid. You got some good deals that dont come along often. That does not mean every one can get 200hp for 900 with a new 2.8. As a matter of fact,
we all know that fiero bolt ons are grossly over priced. When you blow up your 2.8 and put this new one in your going to start racking up the $$$ too unless you do it half assed,
and not replace Mounts, hoses, belts, spark plugs, wires, and so on. Oh look, you conveniently left that part out. That is why no one likes you and flams you. You're a dumb ass on the computer. Hopefully in reality, you are more of a man.

Mine is the 7448, flat track racing model with no choke - the little 350 cfm.

BTW, here is a nice mistake for the books.

I got the carb with a #31 shooter, 6.5 power valve, and #66 jets which made the mix too rich for a 2.8. (it lost power big time)

Soooo...... I put in a #25 shooter, too lean, then a #28 shooter just right, and #60 jets. My vacuum at idle went up to 16 but I got some bucking and bogging at 1/2 throttle, so I changed power valve to 8.5 (the one it should have had) Of course when I installed the power valve I got the gasket a little off center. daaa.......

My fuel pressure was about 8 psi (max for Holley) so when I started the engine the power valve gasket promptly flooded the engine, creating hydraulic pressure in #6 cyl and blowing my head gasket.

So here I am part way through a new head gasket install.

Teedle dee and teedle dumb....

BTW, under full throttle that tach really jumped with the #60's! Can't wait to have it back on the road.

here is my nitrous kit. Please read it

You just got Pwn3d!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1oneoneone!!!!!!!!!!!!!!!! Now please stop posting in this thread before you continue to embarras yourself.

yes I did get some good deals. But it shows it can be done. People have done a 4.9 swap for less then $2500 but that doesn't mean everyone can now can it? But you hear that a lot from people. I did a 4.9 swap for $1k and you can too or else you are getting ripped off!!!!!!

Why dont' you keep telling Linenoise he is going to blow up his 4.9 when he adds nitrous. I mean if nitrous can blow up a 2.8 it can blow up a 4.9 too right? Sure it can. But I dotn' see you saying to linenoise when he said he was getting nitrous that its going to blow up. You congratulated him and told him to show you how to be more like him. Give me a break.

I dont talk to him that way because he is a man, your not. He doesnt post in people's thread that his 4.9 with NOS can beat some one elses swap that costs twice as much. In other words you deserve it. You think you know everything and dont. You assume everything and you get behind a keybord and think you are hard. That's why you get flamed and others dont. As a matter of fact, your the only person I argue with, because I like it and I think I can win the arguement and beat your ugly car. So I am not embarrissing myself. I'm enjoying myself.

Prove that is the kit you have. I assume that you probably got a hacked up kit from ebay. That one says 100 - 150 HP. Your running a 70 shot. That means you would have bought another part making your cost go up even more.

Not looking like the best Idea or the cheapest after all.

Wernt' you just bagging on me for "assuming" things about you? Now you are actually using the word "assume" in your sentance. Hahahahah You are the biggest Hypocrit 3V4R!!!! And you got totally own3d by my posting that link. YOu can't back away from that now.

This just shows you know nothing about nitrous. yes the kit does say 100-150 hp but thats the upper limit. It doesnt' come with jets to add that much hp. The kit comes with directions that state what jets add what amount of hp. The jets I got were for a 70. And even if it did say 100-150 I can easily take it down to a 70 shot by buying a $5 nitrous jet!!! Oh my god that extra $5 just broke the budget on my soon to be 4.9 swap!!! I guess I have to stick to the 2.8.

Want to know what would be even funnier? Is if you drove up here to central florida, got beat my my "tired" 2.8 and then I then went on to tell you that this nitrous kit is a hacked up ebay special!! How sorry would you feel then that I didnt' even buy a real nitrous kit I just hacked parts togethor and was still able to lay the smack down on you. I mean for real. Would you rather me say I beat you with a nitrosu kit I bought from Summit, or would you rather have me say I bought a hacked up ebay special nitrous kit and still beat you. What would you rather hear?

its no wonder your 3.4 was such a turd. You had no idea how to get it to perform well. You were told it had ported heads, you were also told it had a custom cam. Did you spec the cam or know what actual custom cam was in it? Did the guy give you flow numgers on the heads or show you pics of the port work when you bought the car? Or did you just believe it when he said they were ported. And what did ported mean to him? A valve job and maybe a gasket match? Sorry thats not port work. And you never took it to the race track so you never really knew just how fast it was right?

What is your point here in this thread? I dont' really think you have a definate stance in here other then to argue with me be it whatever I say. i coudl probably say the sky is blue and you would argue with me. ARe you against 2.8's? ARe you against 3.4's? Are you against 2.8's with nitrous? Are you against any form of forced induction in general? What is your whole point in this thread?

Mine is that I know that my 2.8 with nitrous can beat a stock 4.9 auto. thats been my stance from the beginning. Just what is your position in this thread?
