Hey hows it going everybody, i was wondering if anybody has changed out a RS camaro into a IROC-Z. And how did they do it?

I wanted to do it with a 1992 RS, but I do not know what stripe set to get. The 85-87 ones or the 88-90, or does it really matter what set fits or do they fit all bodies of camaro's

I'm so confused right now plz giv advice.

Lot more than stripes are needed. But yeah, everything will swap straight over. I've referred to my wife's old 90 RS a "IROC in disguise" considering I gutted a 86 IROC and put everything into her car.

I recently got the emblems for the IROC transfermation i just wanted to know, but im thinking abt putting the 85-87 stripes
I got to get the hood louvers and get it painted, lower the car and do chassis work, wheels the whole nine yards.

Everything will swap straight over. Your ground fx will be "incorrect" for an IROC and if you tried swapping ground fx, some of the mounts/mounting holes are in different spots, meaning you'd hafta drill new holes and/or fill the old ones.

If you found a 91/92 Z hood, the blisters are a straight swap for the IROC louver inserts, so your not restricted to looking for an earlier hood. You can get a later hood, and just swap the blister inserts for the louvers.

Nice, nice, i see what you are saying. Anything else i should need to know?

Other than RS being TBI & IROC being TPI, everythings pretty simple. TBI to TPI is doable, just a little tricky because of the wiring, etc.

Depends on how close you want to come to replicating the Z car options.

As a LONG time die hard Iroc owner, I have to mention that you can't make an RS and Iroc. An RS, with all the decals and stripes and motors and whatever in the world will only make an RS that looks like an Iroc, but is still an RS.

Not important to those with an RS, but OH SO important to those of us with an Iroc.

But hey, I'm an adult, we're all friends, and it is your car, so do what you will.

As for the motor, you COULD in fact get an Iroc with TBI as well as carb or TPI. I don't think there was EVER a V8 offered with one trim level camaro, but NOT on the Iroc. (year to year anyhow) Not sure, but can't think of one.

....and suspension. Beefier sway bars, stiffer springs, better shocks, wonderbar etc. etc.

What's your goal? Because as much as I love Irocs, if I wanted to upgrade an RS, I'd go WAY beyond what a stock Iroc came with. Personally, my Iroc had to be a genuine Iroc (imortant to me) and it has to look 98% stock, but heck, it's SO far beyond performing like one!!!!!!!!

Per my "stock" appearance requirement I've set for myself, I won't change the 85-89 style GFX I have, but I really like the Iroc stripes/decals with the 91-92 "aero" GFX. Consider keeping them.

Good luck with your project, just remember if I'm even in Texas, I'm gonna find you and poke you with a stick for cloning!

tomanahawk

I understand that adding emblems and the iroc kit will not make it an iroc still always a RS.

My 1st car was a 91 RS camaro. I had a V6 it was okay. I started looking into the third generation camaros found out about the irocs and the rest is history...lol

Until I can get an original IROC(which I will) dis is the best way I can get this awsome car.

Thanks abubaca and stephan for the helpful tips and suggestions

But I kinda agree with Abubaca. By the time you buy IROC pieces, you coulda bought bought aftermarkets.

But if your budget is like mine, high-end OEM parts are where its at!

I thought about doing this too when I 1st got my 91 RS, I mean everybody calls all 3rd gen Camaro's, "IROC"s, where I live anyways. But i order to do it right, by adding all the "little" details. I mean, you could possible just do the exterior. Like the black headlight pockets (Not sure if that was a Z28 thing or both IROCs and Z28s), the hood, stripes, tail lights, grnd efxcts, ect. But might as well go all the way and do the interior and driveline/suspension. You could still do some aftermarket stuff too, like suspension and wheels. But part of having an IROC is the fact that it really is an IROC.

All in all, it's still your car

dont forget the the posi rear ends that came in most rear ends of the iroc-z with the G92 package quick ratio steering boxes, steering box braces, heavy duty shocks , spring, sway bars, around here its very hard to find a nice rust free iroc-z so i my self wouldnt mind doing up an RS but like said if i had to start with an RS i would go way over what an iroc-z came with from the factory...

Again I think it goes back to your goal, which I'm still not 100% sure of. Now I could write a book about my opinion of cloning, but this is YOUR thread, and it's your car, so I won't beat you up anymore, but again, it goes back to your goal.

If you just love the way they look, (and who can blame you) then don't worry about performance. After all, 99% people don't know anything beyond appearance, and those who DO know are gonna ask: "is it real?" For cloning or against, no point swapping in 18 year old parts when at the end of the day the VIN number and RPO codes are the only "REAL" things that matter, and of course, you can't really change them. If you like the "look" then just do the appearance parts.

Suspension the issue? - I gotta tell ya, if I had an RS, and you gave me a full Iroc suspension/chassis part set up for FREE, I STILL wouldn't waste the time it takes to do the install. The RS and Iroc suspension differences are all but the same when compared to what only a few more dollars of aftermarket parts will do. My car has full aftermarket suspension, and the car handles NOTHING even remotely close to stock. I mean, I guess you could go cheap and buy used, but I can't really recommend that for a lot of stuff. Sure, wonderbar, swaybars etc. are OK, but shocks and springs should be new, and aftermarket parts aren't that expensive. ...and STBs, SFCs, PHBs, LCAs and relos, Tunnel mount TAs, heck THAT's not even available from a stock Iroc. Sure, those things get expensive, but if you're gonna talk the suspension and handling talk, you better walk the walk, and not too many of us are walking that walk with stock Iroc suspension. Don't get me wrong, no harm with not spending money, and we ALL have different parts and things that are important to us, but bottom line is stock iroc suspension is a LOT of work for such a minimal difference.

Engine / drivetrain your issue? OK, I'm not gonna type all that out again, but it's soooooo close the same issue. I will say that swapping to a TPI (or other intake) style EFI set up DOES open up a lot performance potential, but again, it's a LOT of work, so I can't see ONLY stepping up to stock Iroc specs. You'll want a little more cam if nothing else. -and no point doing that without a full exhaust system. Aftermarket of course, since even the BEST G92 optioned twin cat system sucked. This added power will probably blow up a stock used tranny, so plan on some money for the tranny, OH, and a rear. At least a BW Aussie 9 bolt. THIS can in fact be a stock Iroc part that you can find used, AND relatively cheap. I'll sign off on the rear. GREAT upgrade for the cost. Of course, you'll also soon find that without ALL THAT SUSPENSION that we just talked about, there's no way you'll be able to use much of that expensive power you just bought. Hehe, ask me how I know all this

In case it's taken this long for the lightbulb to go on, you're WAYYYYY farther in the hole than if you'd just bought a Iroc to begin with. Sure, you'll outperform ANY bone stock Iroc, but of course, you wouldn't really HAVE and Iroc. You'd have a totally whoop **** thirdgen that would be totally awesome, but not an Iroc. -and you said you wanted an Iroc.

So maybe it's about appearance. If so, see paragraph two and re-read. Oh, and if it's only about appearance, and you just do cosmetic upgrades like wheels and emblems etc.........

.......I'm gonna come to Texas and poke you with a stick.

1990, I don't believe the IROC was offered w/ TBI

Abubaca

iTrader: (3)

That may in fact be true. Strange 'cause I know there are plenty of TBI Irocs out there, and there are plenty of 91-92 TBI Z28s out there. 90 was a rather strange model year though, so who knows. I really had no specific year to year facts on the motor offerings, but I'd be interested to confirm the 1990/TBI question.

Of course, maybe you saying "I don't beleive" was your way of politely confirming!!!!!

EDIT: Now that I think about it though, are there actually 91-92 TBI Z28s? Surely there are. Maybe?

Rockyd

you know as i always wanted an Iroc/ Z28 i am an owner of a 91 RS 305 i found that since i do have an RS you could do so much other things to it than turn it into a car its not like an IROC i think you should use the money for upgrades or you can always save that money sell the RS and buy an IROC
but like we all say its your car and thats what counts

There are no 91/92 Z28 TBIs. I did a search and found that the question had been asked before, and according to them, 89 was the last year the base engine in the IROC was the 305 TBI, in 90 the LB9 became the base engine continuing until 92.

It wasn't being polite, it was CYA. Camaro's aren't my "strong suit", I know Firebirds better.

hehe, yeah, it's funny, I've spent SO many years geeking myself up on thirdgen knowledge, and now, it'll kinda runs together!

Swapping TPI onto an L03 is a futile waste of time. You guys act like the only difference between the two motors is the intake manifold.

Abubaca

iTrader: (3)

I think most people refer to the two based on their intake, TBI or TPI, -regardless of what else is different.

.....plus I don't know who would put together a nice heads and cam package and run the stock TBI intake.

EDIT* OK, just re-read. Maybe it looks like we're just talking about intakes. That wasn't the way I took it the first time I read and replied. If someone says they're gonna swap in a TPI, I'm hoping they mean the whole engine or better.

BigBoss722

Just so you know... they didn't make IROC's in 92. You're better off transforming it into a Z IMHO. Factory Z spoiler, hood, etc.

Abubaca

iTrader: (3)

No, there weren't Irocs in 92, but it's NOT an Iroc to begin with, and it won't actually BE and Iroc when it's done. ......so techincally it could be a 92 RS, that's a 88 Iroc clone, right???

.......and Irocs are SOOOOOOOOOO much better looking than 91-92 Z28s!

Not sure if this was mentioned. I read somewhere that iroc's received thicker front frame rails.

Not sure if this is true.

Abubaca

iTrader: (3)

Never heard that one. Can't say for sure, but I kinda doubt it.

krisb410

iTrader: (9)

I would doubt that, wouldn't be plausible on an assembly line.

They did come with a "Wonderbar" though, which reinforces the front frame of the car.

impaled

its definietly possible... mine started as a v6 and here is how it looks now. mine is kinda a hybrid of several years, but i like how it looks.

BigBoss722

imo I think the '92 Z28 was the best looking of them all. That hood was ace, and so was the factory spoiler.
