First of all...To all of you guys that have this comment: Just sell you sport coupe and buy yourself a IROC....Please don't make this comment here cause I live in Norway and if I talk about the prizes here you may faint back from your PC...lol....

What I'm really saying is that I bought a 87 Sport Coupe in Good condition for about a year ago...That cost me about 12,000dollars here in Norway...
An Iroc-Z here will cost me about 30,000dollars in good condition...
So as you can see for a little bit cheaper i could convert my Sport Coupe to an IROC-Z for a LOT cheaper than buying myself one...

My car information is:
Modell: 87 Sport Coupe
Transmission: 700R4
Engine: 305 Computer Controlled Quadrajet
Standard Drivetrain and suspension

And the other thing is that I'm just a student so I don't make so much money...

But here is my MAIN QUESTION:
What is the difference between a Sport Coupe and a IROC-Z???
That question sound stupid so I want to say it in a other way:

What parts do I need for a Sport Coupe to get very close to a IROC???

This is what I know about from now on:

1.They have front bumper with gfx, rocker panels, door panels, quarter panels, rear bumper with gfx...

2. They have better suspension

3. ALOT more electrical things such as: power windows, power locks, electric adjustable seats, power mirrors, inside light in targa, fog lights in front, electric rear hacth release.

4. Taillights with grids

5. Hood with louvers

6. Black color in the front bumper "eyes"



Think that is what I know from now....
Can anybody please help me to correct my list???
I need as much help as I can from you...
Please let me know the difference between Sport Coupe's and IROC-Z
I know it would never be an IROC-Z because of the VIN Number but like I said about the prizes, I need to do it this way now, and mayby another time buy myslef an IROC-Z

What I got from now is:

New front bumper and gfx all the way round...
Taillights with grids....

As you can see I'm only in the starting position yes but I think the "look" of the car is most important first...

I hope somebody is answering me even if this thread was very messy written

Thanks....

 

None of those options have anything to do with the car being an IROC or not.

 

An IROC is defined by the different springs (which you'll probably go with aftermarket lowering spring anyways, the rims, a wonderbar (again, aftermarket ones are stronger), the black out headlight pockets, the hood louvers (you might go with aftermarket hood anyways), rear disc brakes, bigger swaybars front and rear, posi rear end...That's about it, for IROC specific. That same stuff applies to GTAs as well.

All in all, just build it the way you want it, but as far as looks go, the ground FX, the rims, and the hood louvers are about it.

 

IROCs can have discs or drums.

 

I agreed to what you said there Apeiron...I thought that IROCs can have rear drum brakes and they can also have a carb engine...Not everyone have TPI's if im not wrong...

Ok...I wasn't sure about the electrical stuff inside the car....
I know the fog lights are just for IROCs....
But I think I will get the most of the elctrical stuff inside the car also....

My plan was to buy some lowering springs yeah....
So then I have another handling just like that...
Shocks will also come in handy cause my old one's are to OLD...

I will have to buy a wonder bar also then...
Very nice to have good handling..

I also have 18" IROC Chrome wheels on my car...
245/40/18 back and 235/40/18 in front...

 

89 irocs had the l03 305 tbi motor, for the base motor.

 

TPI started in 87, so any Z28, IROC, GTA, Trans Am, would have TPI. RS and base Firebirds had TBI. And then, there was the V6. I *think* the Iron Duke 4 cyl was available, in like 82/83 or so.

 

yeah but concluded to the history in 87 camaro irocs you can also get 87 IROCs with 305 carb engine...

 

TPI started in 85, could get carbed or injected irocs

not all irocs have posi, it was an option, as mine doesnt have one

 

Wrong-o.

LO3 Was the base motor for the iroc-z for '89, '90, and possibly '88 too.

Main Difference between irocs - SC's

-GFX
-Nose
-Hood
-Door Decals
-IROC Wheels
-Wonder bar
-'89 + Iroc's have larger sway bars
-Thicker front frame rails
- Stiffer springs

Thats all i can think of, off hand.

My '89 iroc was opted as the iroc, with t-tops, LB9, however it only came with a 2.73 drum rear. That was quick to be replaced by a 3.42 rear however.

It may be more worth your while to just sell your car and pick up a real iroc. Thats what i did, instead of attempting to convert my 85 Z.

IROC's can be had damn cheap. I got my '89 iroc, in perfect shape, with the obvious bad paint, and in need of a tune for $1800. Since then however it has had $4500 worth invested into it (4th gen dash, cammed motor, full exhaust, disc rear, paint, body work, chassis work, suspension parts, wheels etc)

 

Please leave it as is and buy a Camaro with Ground Effects, They are a lot more plentiful than the SC's.

In My Opinion, there are not enought nice non Ground Effect 3rd Gen Camaro's as it is. I am not much of a Ground Effect man though, that is why I have a Formula

 

i didnt think the 87 could come with a carbed 305.....i have an 86 that had a carbed 305(junk) but they used left over engines to get rid of them to use all tpi i thought. im not positive on any of this so anyone else knows im always open to learning more about the 3rd gen. i was told a few times the carbed engine was used up in the 86 models. im glad mine was carbed, less wires and crap to deal with and i planed on a carbed engine to begin with so there is a lot less work to do it. my rpo code tells me my posi rear, rear disc brakes and some other stuff just cant remember right now were special order not standard.

 

The LG4 was still available until 1987. After that the LO3 was the base V8.

 

I believe that Irocs and Z-28s had a quick ratio steering box didn't they? As well some had the Borg-warner 9 bolt rear and an engine oil cooler on the manual transmission models like mine.
Th onlt real interior clues that it's an Iroc is the badging on the passenger side dash and the fog lamp switch on the left dash pod just below the headlamp switch.

 

yea the IROC had the 12:1 steering box vs. the sportcoupe's 14:1 also I was told only the front sway bar was larger on the Iroc, and had a wonder bar bolted between it and the frame, along with different styled wheels certain years it was 15" but most were 16" and the decals and badging ...everything else were options

this dudes in Norway, so I would say it'd be way cheaper/easier to make his sc into an Iroc clone by ebaying the parts needed, over there american cars are expensive and hard to find...esp. an Iroc


I did an IROC suspension/steering swap on my 89 sc camaro....junk yard parts I found verrrrrry cheap.

 

Ok...there is not so very much difference between a SC and a IROC afterall..Like I have mentioned in another post is that in Norway it would definately be cheaper for me to customize a SC to and IROC instead of buying one...So that's my project...So far I have 18" Chrome IROC wheels...Have front-bumper, rocker's, door-panels, quarter panels and rear bumper ready to be painted...

And now I'm looking for a wonder bar and some new sway bar's with bushings and everything...Then after that I think the lowering springs will come and of course some better shocks...

If I will ever find a hood here in Norway I will also buy that of course..

 

Good luck with your conversion. My Iroc Clone from an 85 SC is almost complete. Down to the paint. I ended up doing a full restoration on mine. I bought a wrecked 87 Iroc for all the doner parts. As well as thousands of $$$ in new parts for it. Cant tell it from the real thing now either aside from the wonderbar I havent located just yet.

 

Great...do you have any pictures from your conversion merlin6744??
Would have been nice to have a look on yours..

 

I will have in a week or two when I get the paint laid down on it

 

I'm assuming you don't want to import an IROC due to licensing/tax/duty issues. Wouldn't it be cheaper to take a vacation to the US, buy a reasonable IROC, tour around the country, then place it into a shipping container and send it back to Norway. Import it as salvage auto parts or scrap metal (not as a car) for tax purposes, then strip all the IROC parts for your SC. (or even do the reverse and transfer the Norway legal VIN from the SC to the IROC)

 

That would probably be cheaper than importing an IROC to Norway...But It will cost me a lot of money since I need to take spare time from my work..
And the flight ticket is not here either....And I have never been to US yet so if I'm going in a trip there I will going to stay longer...And sending a car in to a container to Norway is not the cheapest you can do either...And I have to drive it many many miles from the main town in this country to where I live so with gas prices about 2 dollars for 1litre with fuel is not a good choice...

And since I have a SC in good condition now I will rather go for the parts..
I have already got the bumper covers in front and back and all of the GFX around...Now it is time for aftermarket parts like: new sway bars with bushings..Wonderbar and lowering springs and new gas shocks...
Then I have the most of the IROC conversion done..

If I can come over a POSI rear end that would be great to...
And of course the last but very important part is a replacement hood with louvers...

But thank you very much for the idea L69Norm..

 

Just a quick question. When you guys are talking about the wonder bar, what is that? I've never heard of a part being called by that name, I may know it as something else.

 

Hi there fireeagle43...The wonder bar is a steering brace you mount on the front subframe. It is designed to stiffen up the front subframe and reinforce the steering box mount...you will feel much better handling if adding one of this to your standard 3rd gen camaro...

They are no longer availible new from GM but Spohn Performance makes an aftermarket wich is stronger and better...

It looks like this:

 

gotta love the 87 sport coupe, have one myself! it has a host of "iroc" parts itself, such as:

Moog Iroc Springs, Iroc Quick Ratio Steering box, spohn wonderbar, 36MM swaybar, 145MPH cluster, eaton posi...blah blah blah.

on the outside though, it is and always will be a SC...

good luck my friend! my only request on your conversion is that you don't put "iroc" decals on the doors. best of luck.

 

Here is a wacked out idea from the import comunity that is more food for thought. What I have seen my import friends buy has been just the front (A piller Forard Leaving the Dash In most cases) of some JDM car. To save cash on shiping you could carefuly remove the ground efects, Chop the Front clip off with a sawzal and put everything you want on the boat. Not exactly pracital but if it's working to get import motors into this country I could probaly work to get domistic motors out.

 

Whats the big deal with IROCs any way. i mean, i have one, but if i found a regular camaro with the 350tpi engine in good condition for the same price as my "iroc" i would have bought it. the reason i love the camaros so much is because of aftermarket part availability and groups of people that follow them. also they are cheap, easy to work on and fun to drive. In my opinion, i wouldnt add the body kit unless you like the look. Dont just do it to be like an "Iroc".

 

me personaly, I love the look of the Iroc and every since I got my sc I wanted to make it look like an Iroc. SO 13 years later and thousands of $$$$ later I got it

 

On that point one of the sad things of the new mucle car frenzy is that everybody want's the "it" model. They are not happy with having a impala they Want a SS. Or a Lemains they turn it into a GTO. I can go on, Even our early camaro and firebird brotheren would rather have a SS/RS or Z28 over secritary special. Who can blame people some time when you look at the price these cars are bringing in it's hard to blame people for wanting there cars to be more desirable. But with that I will be load and proud that I am geting to drive my cars as they are and not as something else.

 

Ehh...Just to mention my meaning...The big deal with an IROC here in Norway is that if you have one...99 of 100 people are turning around if you drive by them...It is a sport car...Very popular to teenagers and so on....
It is just the way this is..American cars is special cars here in Norway...
We call japanese cars, swedish cars and german cars, regular cars...
every fuc... day I see those BMW's, Audi's, Volvo's, Subaru. Opel, Nissan, +++++ and muuuch more of the same region...

If you see an american car it is something special...And I fell for these cars when I was just a kid..Actually my uncle had an IROC so I fell in love with

But my pont here is that what is special about an IROC:
everything...It is a GREAT handling car even today..Easy to change parts..
The best looking car in my opinion also and more...

I dont like the look of sport coupe if i combine it with an IROC...
So to you guys that has done the same and agree with me on the IROC look...Thank you my friends
But like I wrote before it will be cheaper for me to just do a little customizing with the look and then I have it
