ok, so i did a search, but i couldnt find enough information to make a decision, so i need some answers to my specific questions.

1) Nitrous on a 2.8/3.1 MPFI...good or bad?
2) on a stock 2.8L/3.1 MPFI, what might some expected 1/4 mile times be?
3) on a modded 2.8L/3.1 MPFI with juice, what are the 1/4 mile times? and also, what mods do you have?
4) how much of a nitrous shot is safe on our motors and how often is its use safe?
5) whats better? the 2.8L/3.1L NOS kit, or the mustang 5.0L NOS kit?
6) anyone who has nitrous on a 2.8/3.1, was it worth it?

and no i do not want to spend the money on buying a 3.4.
and a turbo is out of my price range.

and also, please state in your reply if you actually have a nitrous kit on your car, or if you just know about it.

Any nitrous setup will work as long as it has a single nozzle and variable jets (for EFI of course). A Nitrous setup is gonna run you about 500 dollars (about the same as a 3.4 ). You can safely run a 75 shot on a stock motor repeatedly. Running bursts of 125 hp are not unheard of (but I would say a little too much if your car is daily driven). As for times, you should knock off about 1 second for 100hp (probably slightly more). That's 10 carlengths in case you're wondering. Exhaust mods will alow for slightly better times (maybe another 2 tenths 4 with hedders). Direct port injection will net you better gain, but is more expensive than you'll want to spend (and poinless unless you're running about a 200 shot on a "built " motor).

i will sell you a 3.4 shortblock for $300.

Then dont waiste your money putting nitrous on the puny 2.8.

anything on a v6 cept a GN motor a big waste of money!!!!!

ya know...i asked a question because i needed it answered. and so far, one person has answered it. i have a brand new 2.8 under my hood. im still payingit off, i do not have money nor time for a 3.4 unless someone gives one to me. i want to stay with my 2.8 and i want to put nitrous on it if i can. im not wasting my money, if you dont have any constructive critisism, dont reply.

tell me again why youre posting in here? and even more, why we want to hear your BS when weve heard it a million times before? were here building our V6 obviously because we want to, we dont need the V8 guys coming in here and talking crap about our engines. why do you guys repeatedly do this? its so immature and pointless.

I have thought for a while about putting a nitrous kit on my 2.8 and have e-mailed Holley/NOS a couple of times about it. I have heard of people doing a 125 shot without their motor having problems, but a 75 shot is the safest. Holley recommended a wet injection kit to me for the 2.8. Although some people disagree with spending this much money on a 2.8, I like them better than the V8's simply for the fact that you have to figure out for yourself what and how to modify it. If I do get a nitrous kit on this 2.8 I'll be doing a direct port custom job. Yeah, I've driven the 8's...my next purchase will be another 6.

ive read that a wet shot is bad for our plenums because they dont transport fuel very well.


also, what other mods would be safe to do to keep running nitrous safe. and i dont mean fuel pressure cutoff switch or WOT switch or stuff you buy with a nitrous kit.

1) nitrous on any motor is good as long as tuned properly.
2) high 15's
3) low 15's high 14's
4) been answered
5) 2.8L/3.1L kit
6) soon to be answered im sure.

my advice, if not wanted feel free to skip

money sounds tight for you, why not invest in some suspension pieces? your not going to be going anywhere fast anytime soon with a v6 until you get the money to seriously boost it. i can guarentee a set of subframe connectors will be more enjoyed then something you can only use at full throttle.

well im graduating from school soon, and i have a feeling im gonna get some money from my family for graduation, and i really wanna hit 15s with the car. im lookin for a major mod that will help me get there, i can get SFCs when i got some more money laying around between now and then thank you for that though i didnt even think about them do you have them? what kind of improvement did you see?

cause its fun and i hate seeing people constantly do things wrong in the 3rd gen world v6 was built for economy not for performance but you are right its your car and if you wanna spend tons of $$$ on it hey be my guest


if i can keep one guy with a 2.8 from spending as much money as a guy with a civic trying to make a performance car i can sleep better at night

sad thing is you'd get more bang for the $ out of a crx then you would out of the 2.8.
Since you bought a brand new 2.8 you've already made the first mistake. Sure these motors can last forever. Look at Tom p, hes getting close to 300k isnt he? Still orig motor! I just dont see the point in modding a 2.8. Its like sloth racing.

I've heard the same thing about the wet shot, but that's what they recommended to me. Like I said, I'm going to do a direct port and if I didn't do that, I would go with the dry as well.

As for the what mods to get to make your motor last longer? Not much short of a rebuild with lower compression pistons, forged connecting rods, and stronger crank will help out all that much. Keep it tuned up nicely and that'll help. A 75 shot would can be used on a stock engine without a problem, after a rebuild with the things mentioned above, you could do a lot bigger shot. With doing all that work though, you would be much better going with building a 3.4 with nitrous if you wanted to stay with a V6, more power for not much more money.

I'd say build the 2.8 as much as you'd like without putting too much money into it, and then drive it until it blows up. Then go for a full build on an engine.

Why? why two threads about the same subject.

i dont have SFC, i hardly have a thirdgen

BUT...

other thirdgen owners on car sites i frequent have installed SFC and have nothing but great things to say. reduced body roll, better launches, less creaking etc...

my friend has a 89 iroc, waiting for them. hes hooked on suspension mods after installing a strut tower brace. even that reduced creaks, made the whole front end feel more like one piece, alot stiffer. i just think they are a good investment because once their in, their in. if you say go to a carb motor well then your efi nitrous kit wont work. or you might have to tune the nitrous setup differently with another motor. SFC require no tweaking and motivation to scrub your underbody and rust protect it

a wet kit is good on a efi car cause the computer does everyting it needs to do my friend has one on his 4.6L thunderbird and loves it and he uses the hell out of it i think hes been thru 3 or 4 fills by now and has had no problems so the wet kit wont hurt much unless the bottom end or a rod lets go

Guess it's always that one guy who does a wet kit that's way too large for the engine that we hear about blowing up his motor that gives us the notions for wet kits.

I'd laugh so hard if a kid with a CRX with 500 bux in it stomped your ****..... ANYTHING can be fast. Yeah, I'd laugh if I saw a guy with an Iron Duke mod his motor-Oh wait, I've seen one with 600 HP.... Sounds like he's got you beat.... Sux having a V8 now don't it. Go bully on a stock 3.8L 4thgen V6 with any stock thirdgen V8, you'll get your butt handed to you (Maybe not a TPI 350 though).

been there done that my friend has a 99 ta ran him a few times and guess what the third gen wins the 3.4 isnt any better but and omish guy with a horse and buggy has a more dependable ride than anyone who mods a 2.8-3.4 and thinks its the best



how many quick 8 cars are 6cyl's??????????????
ps.! i would rather loose to a honda at least the guys with the ricers know when to quit


now ill stop posting again cause i feel my work here is done and good luck with your nitrous

I dont think its called being a bully. Its called facts. The 2.8 is not a performance engine in the sence that it Gives you VERY little power vs the money you dump into the pos..

And the comment about the iron duke 600 hp? And it sucks having a v8 now dont it? No not really, know why?

FACT for the money you dump into a iron duke to make 600 hp you could make MORE HP with less money on the v8!

Fact, for every fast v6 you find thier is 10 faster v8's.

It's not called being a bully or talking down, its the facts. Not saying you shouldnt mod your motor, hell its your motor do what you want. Just dont expect much from it unless you go crazy and do some serious mods which also mean serious money.
Which brings me to the point that as soon as someone remotely says anything negative about a v6 some v6 owners get bent out of shape, why? Face it, our little 6's will never get to the status level that the v8s are at.

Go bully on a stock 3.8L 4thgen V6 with any stock thirdgen V8, you'll get your butt handed to you (Maybe not a TPI 350 though

Year for year no actually. You need to go 4th vs 4th and 3rd vs 3rd. Comparing old engines stock vs new engines stock is stupid.


Back to the subject. Nitrous, imo its a good idea vs turbo for alot of reasons. Cant wait to use it on my v8.

I enjoy a 2.8, 3.1, 3.4 simply for the fact that whatever you do, there's a chance someone else hasn't done it yet. A V8, yeah, it's been done. my next thirdgen will be a V6 for that very fact. May not be the fastest thing around, but damn will I have fun building it knowing that it's slightly unique. V8 may give more power, but I still find the V6 more fun. Build it and ride it proud.

Brobert pcks up a V8 and switches sides . I don't get bent outta shape, If I wanted a racecar, yeah, I'd build me a carbed V8. I don't need a racecar though, I need somthing entertaining to drive. To me fast is NOT a 10 second car...Tell me about fast when you run in the 7 second range, then we'll talk. I didn't mod my 2.8, I swapped in somthing else, For 400 bux I knocked over a second off my times (and I ain't building a drag car, Care to hit the twisties???). I get offended when someone trolls in and starts insulting people, trying to feel superior. Can't play with the big boys??? I've had quite a bit more experience with various engines than the majority of people, I know what has potential and what doesn't. V6 modders are in it for somthing different, that's more entertaining than slapping your average small block together. :

Look on a V8 owners face when you pass him at half track-Priceless.....

I have a 90 rs with a 3.4 that need building and I was thinking about seeing just what I could get out of it short of a turbo, I sorry but it will take a lot more than 92 octane and nitrous to pass my 89RS with a V8.

Priceless, LOL !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

But is your RS stock???
They way I look at it, racing wise:
4cyl VS 4cyl
6cyl VS 6cyl
8 VS 8

The parked cars or the ones on trailors dont count man! And how come its always "yeah but your v8 isnt stock!" Tech your car isnt either sine a 3.4 never came in a 3rd gen.

I have said the v8s are better for racing and modding since day one so what are you talking about? Do a search i have said my cars in the past have been v8 mustangs and thunderbirds and if i wanted a race car i woulda bought a v8. I have not changed just because i got a deal on the v8.

Also all the BS about weight transfer and the twistes is crap! Its all in the suspension work you have done period!

You know whats so funny? As soon as a rlcer says his crx will smoke your v6 because its lighter you rage on him but you guys use the same fight vs a v8!

you have never seen that look so quit thinking you have and if you wanna get technical my stock 79 camaro with a 305 and a 2 barrel was faster then your modded 2.8 with its whole 155 HP it ran 15.00 and all that had was a flowmaster muffler and a kn air filter

oh and you supposed to hook the nitrous to the engine not to your face !!!

Ok going buy the same prices.....

addmission =$10

10 gal gas(hell ill even use 87 and cut you a break!

My 350 tpi motor coverted to carb= $300

Nx nitrous setup = $500

= your 3.4 getting smoked!!! EASILY!! You refuse to see my point.

Sure you can make more then stock power with a 6. But dont go into dream land and think your smoking many 8's because your not.

You say you think 7 seconds is fast? How many 2.8's or 3.4's do you see doing 7's?

lets get back on topic....

Ok, Well i dont think the 1/4 times will impress you too much from the 2.8 even with the nitrous and since you just got a new 2.8 i dont think its a good idea to put it on nitrous. Just drive the car man. Just mo.

It's all good. I say spray it. We can't ALL have people give us motor tranny combos. It's all about cost effectiveness and reliability. Do what ever is most cost effective and reliable for you. Love your motor and ignore the guys talking about how it will never make any real power. We used to say that crap to the 4 banger guys, now they are running with V8s. Also, remember that we have two extra cylinders working for us, a little creativity goes a long way.

Im just going by the 2.8's dependablity that i've exp myself and seen on this board. I've seen SO many people on here mod the 2.8 and it falls to peices where as someone like TOM P keeps his tuned up and drives it normally and his motor is fine still after what 200k?

Speaking about two extra cyls, that is what its all about isnt it!

I mean mod for mod on each motor the motor with two extra cyls will kick ***. Thankyou for making my point.
