HI there, I have been looking for a parts car and found one for the right price with a WC T5 and posi with Lovres, (boy I love those louvres) The thing is I was hoping to grab all the better brakes etc, however I'm not convinced the car is a real IROC, it is supposed to be a 1989 IROC with a 305 5 speed, it has the 5 speed and decals on the side, but doesn't have a TPI under the hood, this made me suspect, that and with manual windows and no AC, I thought those were part of the upgrade as well. Shoudl I look for other things? I have tried the RPO decoder, however my computer can't install the program, can someone run numbers or tell me what to look for by chance? I don't want to let this car go if it's got the parts, but it might change my offer if it's not a real IROC.

 

For some years, the base model engine in the IROC was the TBI. Sucks, but oh well.

The IROC package didn't carry any particular interior or other options packages with it. However most people who were willing to bite off on the gas-guzzler tax-driven HUGE price increase, also weren't interested in buying a base-model stripper. But who knows, stranger things have happened. Low options is not "proof" of anything one way or the other, except that the 1LE cars came with pretty basic stuff, for minimum weight.

That said, stickers are cheeeeper than parts. Somebody could easily have just put those on there as sucker bait.

If it has RPO code B4Z, it's an IROC. If it doesn't, it's not. Period. That's the supreme determining factor beyond which there is no further appeal.

 

Just check out where the front sway bar mounts up for the wonderbar. It's a tubular brace that connects the sway bar mounting points to each other and sits right below where the radiator is. Only IROCs came with it and most people trying to make a "fake" iroc will just overlook this and slap some stickers on it. Thats how I've always told in the past. Otherwise, I really don't think theres anything else specific to irocs such as engine type, disk or drum brakes, etc....besides the RPO code that it.

 

Along with what sofakingdom said, I typed the vin from that sticker you posted in the compnine.com vin decoder and it comes up with:

Vehicle: CAMARO RS 2 DR
Year: 1989

 

The VIN won't tell you if a car is an Iroc, and the B4Z code only applies to 85-87. On 88-90 cars look for RPO code Z28. Since all Z28's came with the IROC package they didn't need the B4Z code to denote a difference.

Judging by the lack of Z28 on that SPID, it's an RS. Also FE1 is the base model suspension... F41 is in the middle, FE2 is what you'd find on an Iroc. It's a good idea to always check the VIN on the SPID and the VIN under the windshield to ensure they match, since console lids and interior parts where the SPID is applied are often swapped between cars.

 

Wll if it has Posi and louvres and the "Real" WC T-5 tranny, it may be worth it anyway without the brake parts, what do you guys think? It is in really nice shape, no rust but the clearcoat burned off.. I have a 383 ready to put in, just have to figure out emissions...

It has rear drums BTW, haven't checked posi yet...

 

IROCs had the same brakes as base models... unless you are talking rear disc brakes, which wasn't a IROC exclusive.

 

compnine thinks my 1le is an RS

 

Well can anyone suggest me a site that I can decode that RPO I have attached as a picture in my first post? Like I said, I can't seem to get the download working from this site so unless someone can run the RPO's for me I'm flying blind still on what this car's options actually are as far a gear ratios and other things.. It does have rear drums BTW

 

Your best bet is to go to google and search for an RPO decoder, or a list of RPO codes. Or you could pick up a copy of the Camaro White Book and decode them yourself. Or search for the individual codes on here.

Just from browsing the codes, the car is a 305 TBI 5spd car with 3.08 gears, FE1 (base) suspension, 15" wheels... Aside from the 5spd, there isn't anything remotely unusual there. G80 isn't there so it didn't have posi when it left the factory. It's one step above a V6 RS.

 

Just go to goole and search GM rpo codes. You'll get them all. What's the problem?

 

I've personally owned 2 Irocs without TPI, one was a 305 TBI with manual windows and a 5 speed, and the other was a 4bbl 305 auto 86. Both real Irocs. So yes it can be an Iroc without the TPI, TPI was an option.

 

Unfortunately there is alot of rubbish sites for looking up RPO codes, I just looked up mine and one code indicated my 88 is the Miller High Life special from 1984. Compnine can't find any info on the VINs from either my 83 or my 88
