I am just wondering if the G92 coded cars have any rarity to them. I have read up alot on the net about them, I myself have an 89 Iroc G92 car with the borg warner rear and all the other items that go along with that option, and am thinkin of doing some minor changes i.e. 6 speed and maybe LS1, more than likely LT1. I dont wanna change it up if they are hard to find. Thanks, Greg edit, well my first post didnt go well. I apologize as this isnt the first forum I have been on and should have read the sticky first, sorry Moderator please delete

Very rare? No.
Failry uncommon? Yes.

Out of 20,067 IROC-Z's built in '89 (excluding the 3,940 IROC-Z convertibles in which this RPO was dropped this year), only 1,426 had the RPO G92. While not rare like the 1LE RPO, it's still really nice and not very common.

I guess the decision isn't as clear as you may have wanted. While others will have feelings on both ends of the spectrum, the final call is up to you.
I think you should have the kind of car you want, be that original or modded.

We have a g-92 1990 iroc-z, white one at that. It is for sale.

well thanks for the reply. Like I said I apologize for not reading the sticky first but thanks for the info. I wasnt really wanting it to be a "Rare" car honestly, i would much prefer a 6 speed to the 700R thats in it now anyway. It was just that out of the 7 camaros (6 3rd gen) I have owned in my life, This is the only one that wasnt your typical front disc rear drum, or 4 bbl, or well like alot of the others heheh, just on the street camaro, so thanks very much for the info. And I will keep a better eye on the search button before hand. Thanks, Greg

Here is a bit of a conundrum for you...

The Z28 or IROC was like above, about 1% or 2% or so got the option. On the other hand all LB9/M5 & L98 "350" FORMULA's and all GTA's would have the same exact equipment as the G92 (performance axle) but they did not get the RPO unless they got the 1LE option.

In the end you will have a better chance of finding the performance equipment on a Formula or GTA than an IROC or Z28...

So it really depends on how you look at it...

Actually, you could get an LB9/M5 without the G92 in 1989.

Checking off the G92 box got you the N10 dual cats, (in place of a single cat) and 10 more hp, an oil cooler, PBR rear 12" discs (in place of drums) and a 3.45 axle ratio with limited slip in a BW 9 bolt, (in place of the 10 bolt and 3.08).

Previous to this, G92 was just a performance axle ratio. In 1989 it bundled afew performance options together - and it was only available on the coupe, (not convertible or T-tops). The N10's, BTW, were available late '89 on the G92 package.

The 1LE was triggered if you ordered the "G92" and specified "AC delete" in 1989.

And if you ordered a 5.7L with T-tops, you were also restricted from ordering G92. But you did automatically get the BW rear with PBR brakes and a 2.77 gear.

Do you live in ct? there is a guy who has been trying to sell a G92 car since like Nov i think. its in wicked good shape, but his asking price is really high imo. i have seen it on autotrader, ebay, c-list....
Figured i'd ask.

No Actually I live in Arkansas. And on the equipment, My car is a coupe with 5.7, BW 9 bolt, dont know how many cats it had as the previous owner changed out the exhaust with headers and after market the rest of the way back. It had the bigger brakes up front but were also changed out by the previous owner. The gears are also 3.73, which was also done previously. It runs exceptionally but just gonna get more out of it now that I know it isnt really a rare car. just hope the BW rear can take it.

Interesting thread. I've often wondered why I don't have the G92 RPO on the GTA. It's a 5.7L, 3.27 gear, 9 bolt BW, oil cooler, solid roof, big rear disc brakes.....It's got everything except for the dual cats.....No G92 for me.

No GTA got a G92 option, but for all intents and purposes they ALL got the G92 options. THe reason your car does not have the N10 is that became standard mid year for the GTA, it was earlier in the year for the Formula.

I think the only thing that is not included and is "optional" is the Aluminum driveshaft... But I am not sure if that was part of the G92 or not. I want to think it was part of the 1LE tho.

JOhn

Since I have a G92 IROC, I'll look at it as a rarity.

Sounds about right. My car has the aluminum driveshaft as well.

I guess in heindsight there are some LB9/A4 GTA's that do not have G92
