Hi all, after viewing all of the decoders here and trying to determine whether or not my IROC was indeed an IROC or a well-dressed RS I found a great link to that tells you. Why you may ask, well I adopted her and want to know her true heritage! - Anyway I was pleased to find that this link from Carfax provides you the answer for free. It will clearly be listed; as mine returned " Year/Make/Model: 1990 CHEVROLET CAMARO IROC-Z." Needless to say- I was very pleased, and I bid you the best of luck as well. I also ran another VIN I found on this message board and it returned "Year/Make/Model: 1990 CHEVROLET CAMARO RS."

Anyway here's the link:

Hope it's useful,

do you know any web site that will tell what options your car had orignally

 

Not off hand, I would first recommend going through anything posted by Sticky. It can't be the first time the question has been asked. I see alot of talk about RPO codes, I don't know if it'll help but it's worth a look. Also, I've seen a few members that have access to some sorta GM (I think) database. From what I can tell, if you ask them nicely they may be able to get you quite a bit of info from your VIN code. Hope this helps, -for what it's worth.

 

i would like to run my VIN but i cant justify $20 just to figure out what my car really is.

It tells me that its an 87 Trans am with a 5.0L which is exactly what i expected. Even though it doesnt have a 5.0L in it anymore.

 

Sometime ago, there was a thread about identifying the GM build
sheet, given a VIN. I'm not clear on the details, but the service
was provided by a young lady (also an F-body enthusiast) that
worked in a GM office where such records were kept. I.E. she did
this gratis for board members. The best I can suggest is start
searching on the tags below. If you can get the build sheet/RPO
codes, there was (is?) an RPO decoder utility downloadable here.
(Build sheets are usually attached to the underside of the console lid,
or somewhere under the carpet, in the back seat ares.)

Good luck

Hi, That was a great site, Found something on a car I was going to by. Thanks Ray

 

You can try this.
I did not have any luck on my 85 Z though.

cool. Here what they DMV posted on mine at least is it accurate:
VIN: 1G1FP87H9FL102848
Year: 1985
Make: Chevrolet
Style / Body: Coupe 2D
Engine: 5.0L V8 4BBL
Country of Assembly: United States
Model: Camaro Base / IROC Z28 / Z28
Even it was born a coupe and not a vert!

 

I got an '89 IROC and it said mine was an IROC Z28/RS??? I don't know what's "RS" about it though. lol

 

Did you have any luck with the option decoder?

 

no, it wanted me to pay for other info.

 

They reason they all say Camaro Coupe / Z28 / IROC / whatever is because that is all you can tell from the VIN. The only way you can tell what model you have from the VIN alone is if you happen to have a motor what was only available in a certain model, and most VIN decoders aren't smart enough to figure out that.

 

Try this:

did not work for mine ???
vin 1g2fs23e2m1244815

 

You sure you read it correctly? The "1" after the "M" could be an "L". If so, that is a valid VIN:
http://compnine.com/vid.php?vin=1g2fs23e2ml244815

 

If that is your VIN you definitely don't have a 91 Formy like you state in your profile.

 

http://www.decodethis.com/Default.aspx

this is the only site that pulled any information on my car

 

how do you tell if your car is a true GTA or not, every site ive tried the VIN on says its an 87 Trans Am, i dont have any RPO codes or anything, the centre console was gone when i got the car, and the stickers have gone or been painted over on the doors !

 

compnine is gone now.... the VIN decoders work, but unless it was an L98 or LB9 car it simply was not a IROC or a GTA

My insuirance company lists my B4C as a Z28, based on the engine code int he VIN. I had to prove to them it was not a Z28 but a true special service package car.

OK, here goes, I did a vin code search and this is what I have:
year-1988
Trim GTA Hatchback
body-hatchback 2 door
4 seed w/ overdrive
M.S.R.P. $18509
tires 245/50R16
wheelbase 101.00
MY question does this mean this is a GTA? If so it has none of the emblems or items listed here. But by checking when the car was originally bought, it was purchased in Oct.2 1987. I know this because I have the original warranty/owners assistance manual and have talked to the guy that bought it from the factory.

 

It does not mean it's a GTA. You cannot tell a TA from a GTA using the VIN alone.

 

AmorgetRS is very much correct on this. Aside from Compnine.com, which is limited to Canadian only ThirdGens for that time period, I'm not aware of any other online VIN decoder that actually polls a GM database and retrieves the RPO codes for the supplied VIN.

What you will find is several, generic, VIN decoders that simply break the VIN into sections and decodes them. Because the Trans AM and GTA both share the same VIN prefix of 1G2FW, the generic VIN decoders will return a "Trans AM/GTA". The online decoders don't really look up your specific VIN in GM's database to get specific information from that specific VIN. It's a generic script instead.

 

That works for me so that saying there were more GTA's built than T/A's according to stats. Crazy but it's here on the site. Again thanks.

 

COMPNINE is back????

 

Sooo what exactly is the 1SB package?

Wow, my car is an RS with the Z28 package? what?

 

mine says its a 89 camaro with IROC Z trim level on Decode This. I am pretty sure its not an IROC just a regular ol' RS with a 5.0

 

Glad to hear yours is a Iroc, I did it for fun because i know i have a v6 RS but motor said EFI, is there a difference from a EFI and a MPFI? Weird Not what Car Fax read.
I looked up EFI and the motor looks different then what i have.

 

Thats a awesome one! Here is mine!

I need to add, the information I posted was from a VIN look up that said it had the Iroc Trim Package. I really do not think it is an IROC because I purchased the vehicle from the second owner with 28k miles on the car and it has RS badging. I did a RPO lookup with the thirdgen.org RPO generator and it doesn't say anything but it has WW4-Appearance Package #4, 1SD-Option Package 04, and it has DX3-Stripe Delete (not sure what stripe its talking about). I was pretty shocked to find it was supposed to have the DE1 option-Rear Window Louvers from the factory. The RPO codes do not have a B4Z package so I do not think its a IROC. I am guessing its just that the ground effects are the same with all the camaro's no matter if its a RS/Z28 or IROC that made that come up with the VIN decoding
I find it funny that the MPG on your V6 is only 2MPG HWY and 1MPG City more than what it says for mine which had a 5.0 TBI

The VIN cannot tell you if it's an IROC or not. Since you seem to have the RPOs from your other post, if it has the Z28 RPO it's an IROC, without that it's an RS. The VIN decoder is just making an incorrect assumption.

 

yeah that's what I figured, since there was no RPO code on the car saying it was a Z28 or anything I figured it was just the VIN decoder making mistakes as it doesn't know how to differentiate which model the vehicle is by the VIN. I just thought it was strange that others that used the exact same site said theirs told them theirs was a RS. I really didn't think it could have been a IROC as I purchased it from the original owner with 25k miles on the vehicle and they never tried to represent it as an IROC and only ever mentioned it being a RS

 

i typed my in my vin (1G1FP21E5JL146754) and it said there were 42 records on my car. does anyone know how i can get a report on my car for free? i looked up the vin and it said 1988 IROC-Z but it doesnt have any badges or codes for the IROC-Z. i would just like to know if its a true IROC-Z or just a special ordered coupe.

Thanks Andy

 

So how exactally do you make it inot a vert???

 

I used this and its a IrocZ
http://www.kbb.com/vehicle-history-r...b-f5cec41d3ecb

 

this thread just keeps going lol

ASC converted thirdgen's into "factory ordered" or "dealership ordered" however you want to look at it...... verts

all verts started life with a roof

as stated before a vin can not distinguish trim level, only your RPO codes and possibly the options your car has if original can determine which trim you have

your report could very well be right and you have an iroc, but then again, you could have an 86 Z28(without the iroc package) and still have the Lb9 motor

do your RPO codes match up to it being an iroc?

 

incorrect and worthless info to be found here

 

Hi guys just wanted to ask if 88 base firebirds came with the 305 f code

 

No, to get the F code (TPI 305 LB9) motor it would have to be a Formula.

 

I ordered a vehicle invoice from the gm heritage center.because the door sticker as well as the SPID in the console are illegible. its like a window sticker, like the one that was on the car when delivered to the dealer that bought it.it lists the dealer,all the options the car was built with.everything. so if your SPID is missing ,and you really want to know. $50 gets you all the information you want

 

it only goes back to 87 for ponitac. My car is an 86.

 

That is because PHS covers pre-87 Pontiacs

I am looking to buy a 1988 Chevy Camaro IROC I know there were two different engine sizes for that year 305 and 350 how can I tell from the vin the engine it has in it. Or how else can I tell the engine size. The seller inherited the car and has no information on it.

 

Check the 8th digit of the VIN. 8 will be the 350, F will be a 305.

That will at least tell you what the car came with, but may not be what's actually in the car now.
