I have read that G92 was a mandatory option with the 350 Z28 in 1991. Ordered without A/C triggered 1LE. I cannot find any information on this for 1992. All I've read is in the 1992 Chevrolet product line brochure that states, "Optional performance axle ratio is available only with Z28 coupe with 5.0 Liter TPI V8 and 5-speed...." If this is true, it does not explain how the '92 1LE with a 350 gets built as it must have G92. Anyone know the truth on this?

Willie, I think there may have been a mis-print in the sales catalog, in the '92 order guide the G92 option was required with the B2L 350 package, but optional with the 5.0 TPI and manual trans Z28 coupe only, also the t-top option was not available with the G92 package as well. Chris '87 Conv.

Willie, heres probably the answer. Here is a pic of the RPO sheet in my 1992 RS B4C/1LE 5.7L, as you can see no G92 code. I did reserch and found that other codes trigger G92 without G92 on the sheet. I have seen some other 1LE's like this. I know I have G92 so B4C or 1LE must trigger it. Also for insurance reasons my VIN triggers Z28, but no Z28 code, I thought I could pull a fast one on my insurance company with an RS, but no dice.

Very cool! What color is your B4C? My '92 Z is Dark Teal Metallic.

I'll take a look @ the brochure I have from '92. I believe it states that G92 is mandatory with the L98.

It is black from the code WA-8555

Mine is indeed black, I don't have a 1992 broshure, but I believe you are right. I believe G92 is 3.23 for auto and 3.42 for 5 speed (correct me if wrong) In my case B4C gave me the 3.23 ratio but no G92 on the sheet. However all evidence I can come up with is that all 1LE and B4C included G92 but they did not put it on the sheet (weird). Benny

I have a 91 RS with the 3.1 v6. My RPO code says G80 and I have the 3.23 axle ratio. Whats the difference between the G92 3.23 axle ratio,and this one? I thought the G92 was a 3.42 axle ratio?

The 3:42 ratio was not a option with the 350 only with the 305.

Basically G80 means you have a 3.23 posi axle. Obviously you've got a automatic. The G92 code for the TPI 305 gave it a 3.42 ratio. If you had a manual you'd have a 3.42 ratio, i've got one it mine.

harry's91rs

I have the G80 and it doesn't have a posi (I've done many burnouts before, its a one wheel wonder. ). I know that the G80 is the 3.23 ratio, but could there be another code to trigger the posi with the G80?

Sure it isn't a toasted posi, they do wear out

RPO Code G80 = Positracion.

My car does have 105,000 miles. I thought that i didnt' have one, i guess its just worn out.

harry, 3.23 gears are going to be triggered by the code GU5 on your SPID sheet.

and it does sound like a toasted posi....

benny..

i honestly think that regardless of models, these cars don't really fluctuate as far as insurance rates..... they may vary based in different locations obviously, but if you compared two models in the same area, i don't think they'd differ very much.

i'm 20, i have an 84 sport coupe, and an 84 z28. my parents contacted their insurace company, and it is going to cost me $800 a year for both cars for liability only. i was really surprised that both cars cost the same to insure.

Benny

G80 is limited slip (posi) diferential, G92 is 3.23 or 3.42 (manual) G80 is NOT axel ratio. Your posi must be fried.

The insurance for my 91 5.7L Formula is the same price as the insurance for my 91 3.1L Firebird. Liability only, I'm 25, and I haven't had a ticket on my record since 1999. Insurance on my 92 S10 2.8L 5spd was more expensive by about $10.

Insurance depends on how many cars and drivers you have, who is the primary driver and on what car, and how the cars are used. You can easily pay more on a policy taken out on a 1996 Grand Prix with you listed on it, then the wife listed on a 2002 WS6. Same policies but arranged differently, and it's kind of funny how insurance agents will actually tell you which way it would be cheaper.
