3rd Gen Z28 VS IrocZ

[ViperJ]

Okay so I have finally decided to sell my Camaro and to buy a V8 3rd gen. My ideal car is a 92 IROC, but I have a few general questions

1- HP ratings, and is it worth buying the IROC over the Z28?
1989- 5.0 TPI V8 215 bhp.
IROC: 5.7 TPI V8 240 bhp.
1990- 5.0 TPI V8 215 bhp.
IROC: 5.7 TPI V8 240 bhp.
1991- 5.0 TPI V8 215 bhp.
IROC: 5.7 TPI V8 245 bhp.
1992- 5.0 TPI V8 215 bhp.
IROC: 5.7 TPI V8 245 bhp.

2- What is quatermile times for these cars? Or how much quicker would the IROC be over the Z28?

3- INSURANCE- I haven't been able to find a place online that will give me a quote for an IROC, they just list the Z28's. So if you have a 3rd gen what are you payinf for insurance, and who is your carrier?

I am sure once I post this I will have more questions but for now thats it.

they never made a 92 iroc, i think they might have made a few 90 irocs but IROC stopped using camaros in 1990

[KPot2004]

oh and the IROCs and z28s are pretty much the same thing

They write that the IROC was dropped but the motor specs still list it, so what motor was the 5.7 in?

Also RS isn't like 4th gens right, a RS can be either a V6 or V8?

So what are the main diffrences between the Iroc and the Z28's?

They are the same thing, except IROC was used in place of Z28 for a while. So your ideal car is then a 92 Z28 with the 5.7 TPI.

[KPot2004]

ideal would be a 92 with an lt1

[ViperJ]

So how much a month do you guys pay for insurance, and what company do you have?

[Morley]

When they made the Z-28 & IROC's at the same time, the IROC had better suspension, the 245 50VR 16 tires (16" rims) and sat 1/2" lower than the Z-28. You could get the same engine & trans in either one.

[Xbox2202]

If you get a 92 Z28 it would have to have a 5.7L engine because all 92 Z28's came with that engine.

for limited covereage i was paying 140 and for full covereage now im paying 190. Im only 18 but have no accidents or tickets.And i live in texas and have alstate...if i were you id buy an iroc...just cause its an iroc....not really that much of a difference i guess you can kinda say its like z28 and ss with the 4th gens.

[AFI 05]

I live in CA and I pay $125 a month for my IROC. Not too bad for full coverage.

[89IROC&RS]

i live just south of D.C. and with no collision or collateral coverage i pay about 120 a month.

as far as the power output of the cars, its pretty much the same for those years, the only differences were in the camshaft specs that i know of. unless you got the dual cat setup. Since most modifications include the heads, cam, and exhaust anyway, i would decide baised on the other aspects of the car, like its paint, interiror, suspension and stuff like that. seeing as the engines are very similar, and the most likley mods youll make are to those aspects of the car.

ewwww why they have such low horsepower?

[tcfco2005]

its not that low considering the what year it is....compare it to the mustang of those years...and thats why the hp is at what its at.

iroc-z has slightly different ground efx and is about 1/2 in lower than a Z. iroc has better suspension (shocks, bigger sway bars, front frame renforcement), and bigger wheels and tires.

85-87;
-iroc is an option package for the Z28 (my insurance had no idea that my 87 was an iroc because it is not a separate model);mutual benifit insurance
-85-86 Z28/iroc; highest engine is 305TPI were as 87 iroc can have 350TPI
-85 305TPI=highest hp 305tpi because of a better cam, 215hp
-B4Z is iroc RPO
-305 4bbl is base engine in Z28/iroc, 305+350 TPI optional
88-90;
-iroc is it's own model (no hiding the iroc option from insurance) although Z28 is the RPO used
-305TBI is base engine in iroc, optional in base coupe, 305+350 TPI optional

there was no 92 iroc. 91-92 Z28 had TPI engine
91-92 RS had 305TBI as highest engine unless u ordered the B4C police package in which both TPI engines were availible.
