I havent had my RS long but i used to have a Iroc and i didnt have any problems with it at all. The engine seems good i have already beat 2 irocs!! But on the board yall seem to have alot of problems with the V6 motor and transmission. Is this engine as strong as the iroc?? please give me full details on this engine. Should i take it easy or is it ok to hot rod it a little bit?

 

I've never tried to race a Iroc or GTA.
At one time my friends has T/A's or GTA's.
I could keep up with them but never out power them.

Engine and transmission still going strong after ~150,000
Not much in Hi Po Parts.

 

Treat it good, replace things that need to be replaced on time, and be picky, and these cars will usually treat you good back. I used that formula on my Camaro before I sold it and it was reliable as hell except a few small incidents. Not to mention it was pretty peppy.. And I CONSTANTLY used wide open throttle because I couldn't bear the lack of acceleration otherwise.

 

I have A 75 HP nitrous shot on my 1992 3.1 liter V6 Firebird. It has been on there since spring 1996, and for more than 100K miles. I don't use it very often anymore, but I have probably run 25 or more bottles of Nitrous through it over the years, and have experienced -zero- problems with it. I maintain the engine regularly, and fix anything that goes wrong, but I don't baby the engine. I like full throttle takeoffs just as much as anyone else. Mine has 170K total miles on it, and I have not had any problems at all out of the engine and tranny.

 

That's just because there's not much aftermarket available for the 2.8 or 3.1; so you see all the "help" messages.

They're not that obvious on the tech board because there are tons of performance parts available for v8's, so there's much more performance questions.

Transmissions are the same build as v8 ones, besides a smaller case and two weaker internal parts. But those weaker internal parts aren't the cause of the trans failures. Year for year, a v6 trans matches a v8 trans. 84 4-speed auto, for v6 or v8, will have the same problems- early death. Same with 85. 87 marked the biggest year for improvements to the 4-speed auto (700r4). The newer the 700r4, the stronger it got.

Hot rod it to hell, dude. I've got over 248,000 miles on my original 2.8, bought it when it had 65,000 miles on it- and I still floor the gas when I can.

 

kool kool, thanks for the replys it had me worried. haha but i get it now. Thanks

 

I'm just curious, from who did you get your nitrous kit from? I was looking into the nitrous kit from Holley for my 3.1L camaro. how was installation? did you do it yourself?
The thing is that i have relativly low miles on my engine 53K. It runs excellent and I plan on keeping my car. In the near future I'd like to add at the most a 75 shot of nitrous to my car. Do you have any suggestions on getting me started? Advantages and disadvantages of your system etc? You're help would be greatly appreciated. Thanks

 

I believe he used a kit for a 5.0 liter Mustang, not sure from where...

 

The kit is a NOS brand one, and it is for a 1986-95 5.0 liter Mustang. It is a dry flow system, which means that it sprays the nitrous into the front of the engine, but puts the extra fuel through the engine's fuel injectors instead of dumping it into the intake. Mine is an adjustable kit from 50 to 150 HP, and I set it for 75 HP gain. They have a kit advertised in Summit for the Mustang that is non-adjustable and is rated at 75 HP gain. It sells for about $460, and I think that it would work great with our 3.1 liter or 2.8 liter fuel injected engines.

I did the installation myself. The hardest part was drilling and tapping a 1/8-27 NTP thread into the throttle body in front of the throttle plate. The wiring wasn't too bad, and running the lines wasn't too bad. Other than the drilling and tapping, if you can install a car stereo amp and can change a sink fixture yourself, you should be able to handle it. Mine also has a micro switch so that it doesn't activate until you both arm it, and floor it. That is the way it should be, but if you get a kit that doesn't have a throttle activated switch, it wouldn't be too hard to get one and rig it in there.

 

YOU HAVE A SMOG PUMP!!!

:lala: :lala: :lala:

 

Yes, and I believe that all 1992 Firebird V6 cars had them. I have done nothing to the engine other than add the nitrous, and it has been totally reliable.

 

Thanks for your help I'm glad to hear that installation wasn't that hard. I've wired all my stereo stuff in so i think i can handle the nitrous hehe. thanks again!

 

I've seen dry kits installed on tv and it looks like I could do it with my hands tied behind my back. But of course they edit out all the gruntwork...the dropping of tools...the cursing....

 

Yeah, well it doesn't look that hard to install and that makes me happy. I'm calling my project "Project Sleeper" I'd like to mod my V-6 out a little bit and take it down to the track and see what it can do. Maybe beat a couple of V8's??? hehe. I'm about to redo my whole exhaust system. I just bought the Dynomax cat-back system and I'm putting that on this weekend. I'm waiting for IROC57TPI's shop out in michigan to finish fabricating a y-pipe for the headers and I'll order that as soon as i hear from them. Still deciding what cam i would like to put in my car. I still have to do some studying on that. Then the nitrous and ignition system. And of course upgrade my suspension. I have no plans on selling my car anytime soon so why not go for it huh?Tell ya the truth, i get sick of going to the car shows and seeing all these V8's that all have the same stuff. i wanna see a modded six-banger lol. I don't expect to see a HUGE increase in power but I'd love to see my car turn a few heads at the track and leave people thinking "did that chick just beat me with a 3.1L v6??" lol.

It could happen.....maybe lol

 

Heh...with some mods, it'll be turning decent times. I didn't have any major victories in my 3.1 before I sold it, but it definitely turned heads. It was faster than people expected. Here's a tip...these cars haul serious nuts off the line.. So if you want to impress someone, take them for a drive in a really cramped area...like a parking lot...try to do most floggings from 0-30 mph. These cars will hang with some V8's from 0-30. Everyone I took with me in a ride thought my car was fast as hell because I used that method. Then I showed them the engine. Their faces:

 

so from what im getting from this post is....
i can buy this Performer EFI Nitrous Kit for a 86-95 5.0L & 96-97 Mustang that adds 80 horse

it ill work with my 3.1??

 

i agree, when im at the track i call out some v8;s and beat the majority of the off the line, 60 f. and sometimes even 330 ft (like the 92 5.7L z28 )

but as soon as i get 1/2 way though second thats it no moew t

 

hmm..now when i just floor it, at 1st my car doesn't want to go say when I'm goin from 0-35 but when I hit the higher gears and i'm at about 50mph it really pulls. It feels like the car hesitates for a second and i can feel my wheels almost spinning then it slingshots forward. It's gotta a lotta umph.

 

whats all done to your car??
you an see in my sig all mine

all combined there produce one KICK *** launch, just if i had some tires that gripped i would be in much better shape

 

Erin...check your ignition. Sounds like weak ignition causing low-rpm bogging to me. Mine was the same way. Weak coil and bad pickup coil...I had this nasty bogging-down...when the car DIDNT bog down though it'd light the tires up if I floored it!

 

Ive only done what i call mini mods to my car. All i've done is add a K&N filter and ASP crank pulley. My car really opened up when I put the filter in cuz my old one was really clogged. Every thing I've done to the car can be found here

I've just replaced my front endlinks, bushings and transmission mounts with Energy Suspension stuff, New KYB shocks, radiator lines and 180* thermostat. this weekend i'm putting the Dynomx cat-back system in.

I thought about replacing my ignition coil but i wasn't sure what brand to go with. However, everything finally seems to be running alright so i'm not going to replace anything yet

 

Wow, you've got a really hot car... NICE! I LOVE the shifter assembly too....

You can buy a coil tester for like $7 at your local auto parts store...think I found mine at Discount Auto Parts. It's meant to be used to check for no spark, but it can determine coil voltages if you watch the color of the spark. White is new, blue is normal (old coil)...anything other than blue or white isn't acceptable if you want the car to run/perform decent. MSD makes a GM HEI direct replacement....so does Hypertech and Accel. I've heard mixed reviews of the Accel unit, but mostly positives about the MSD and Hypertech. I switched to an MSD Ford TFI replacement coil on my stang and felt an improvement... My stock coil was sparking blue.

BTW...I hope you enjoy your Dynomax system! I enjoyed the HELL out of mine! It's funny though...I didnt notice the power gain as much as I thought I would until I raced a friend of mine. He used to beat me by a car length. After the catback, I had him by a car length in first gear, and two car lengths a little ways into second. WOW was I happy. Your car will gain a LOT of get up and go from that catback.

 

Hey thanks. The B&M Megashifter looks good but i think it's a POS. My cable keeps binding and it doesn't shift real smooth and the electric switches for the lights are very delicate and they keep on coming apart causing me to drive around with my reverse lights on when I'm in drive. I gotta find a shop that deals with high performance transmissions and shifters and get that fixed.

Well, while my boyfriend is putting my exhaust on i'll have to check the spark on my ignition coil and maybe take a trip out to Summit. I also put white face gauges in and red bulbs to make them glow red. The red doesn't glow very bright so i gotta switch them back to the stock bulbs. I hate taking the cluster apart. There's like 3 layers of plastic to take off and all those tiny screws. I got busy day ahead of me.

 

i used blue lights cuz they matched my cd player glow, and the stock white was WAY to white!!

 

V6 Fbody cars CANNOT beat IROCS AND GTAS

 

Unless their motors are blown. Or the trannies. My V6 Camaro could whoop the living sh*t out of a buddy of mine with an automatic T-bird with a carbed 302 swap.

 

Well, we put the Dynomax Cat-back system on ad man, what a difference!! I felt the difference as soon as i hit the road(and floored it of course) I'm really itchin' to get the headers and replace my cat now.


Hey Dennis...This V6 will beat I-ROCS and GTA's hehe Give me time......

 

Catbacks kick *** on these cars...they really enjoy the extra flow.

 

Hey pontiacguy, what time range did you run in with your nitrous system? just curious...

 

Anyone wanna take up bets? I'm betting he got 15.9.

 

hmm...I was guessing low 15's. Like 15.4.

 

Hmm....Upon re-evaluation, I think I was being a little too pessimistic as usual. 15.65-15.7

 

After reading this, I miss my 87' Camaro with the 2.8! Maybe I'll look for one and see what I can do...

 

Hey guys... I have been out of town for the past week, so I haven't been able to check my e-mail.

I have never had my car on a track. I plan on changing that this summer, but I have never really cared about track racing, just wanted more power on the street.

I will say this, I can beat a stock 5.0 liter 5 speed Mustang. I said Stock, so no flaming me! I know this because I have done it more than once. It is pretty close, though. If they have put catback exhaust and power pulleys on there, then they will beat me. I can tear up a convertible mustang, or a stock Impala SS, and I am talking about the mid 90's ones that were RWD. Stock 305 camaros and firebirds I can beat, especially the TBI cars. They are really easy. Anything any faster than a stock Mustang 5.0 will get me, but oh well, it is only a 3.1 liter engine, and other than a catback, high flow cat, and the nitrous, the engine is stock. I don't even have an aftermarket air filter.

Of course, when the bottle is empty, then the fun is over.

 

Hmm.. looks like I have a new theoretical ET to beat.. oh well. More boost.

 

i've noticed that alot of people on here have taken out their smog pumps....are they really that restrictive? since we dont have any emmisions testing at all in georgia (ahhh, it's nice), should i take mine out? if so could you give me brief instrucions on it? i don't think i've ever even touched my smog pump before, let alone think about messing with it, but if it's worthwhile let me know.

They're basically extra weight that takes up some HP from the drivebelts. Plenty of f-bodies came from the factory without them (like mine), and still pass emissions.
