All right guys, its my understanding that the only differences between the 1987-1990 Camaro’s is they came in three option classes, IROC, Z-28, and RS. Furthermore, in 1991-1992 there were some minor interior/exterior changes.

The IROC’s weren’t anything to special, tuned port injection, different spring rates, bigger tires, bigger rims, bigger sway bars, the like, nothing that couldn’t/wouldn’t get replaced on any car I get, Z-28 were a step down, some came with carbs, but the basic options were still there (ie: 5 speed, and all other interior options that came on the IROC’s), And the RS was an anemic Camaro that had a 6 banger, here is where my question arises, what are the exact differences in the RS and the Z-28, I want to buy a Camaro and swap a used 1994 LT-1 with a T-56 six speed, so the engine part is not really that important. Did the RS’s come with different gauges? Did they come with a different rear-end Gears? I need to know specifics. I would really appreciate a lot of pictures with this one guys.

Now about the swap, would it really be feasible to do a 5.7L T-56 swap into a third gen that came w/ a little 6 banger?

Dash gauges? I believe they stopped at 110, unlike the 350 Z28s that came with 145mph

Depends, do you like the LT1? It's bascially a direct swap in from what I hear. If I was doing a swap like that, i'd move on up to the LS1. It'll be a pain because of all those damn sensors and wires and all that good stuff. But it's a hell of a lot faster than a LT1. In fact, I'd say it run with some of the better modded cars here.... stock.

ok RS' were only available from '89 to '92, the only two gear ratios were 2.73 for auto and 3.08 for manual. Most manual RS' were posi also. Z28s only lasted to '87. 88 was the first year of the TBI and it was available in the sport coupe (RS replaced the sport coupe). Basically, the 2.8 V6 was base in the RS, but the 305 TBI was available. IROC's base engine was the LG4 until the '88 year when the TBI came out and that was the base engine (most people sprung for either the LB9 TPI or L98 (B2L package) TPI)
There really isn;t a whole hella lot of a difference between the RS and Z28, however when the IROC disappeared in 90-1/2, the Z28 was basically the IROC from then on, and the RS was like the old Z28. You should probably buy a camaro with a v8 cause the front springs can handle the weight and its a little bit easier having the hoses and crap almost in the right place for the LT1.
If i missed anything maybe someone else can fill you in around here.

 

They did a lot of skimping on the RS. Not so much with looks or interior but in the suspension.
