Can anyone answer me on these few questions:

1. Was rear discs optional or standard on 92 T/A's? If not, what options gave rear discs?

2. Is the rated 245hp for the L98 with or without dual cats. Also, was dual cats standard for this year?

3. Was the Th700r4 the only available Auto for 1992?

Thanks,

Ken

 

1)G92 coded cars came with the rear discs only I believe.

2)With dual cats only on Camaro's, the T/A's had 235 or 240hp due to different inlet tract.

 

Hit the enter button too early.

3)Yes

 

Nope, my car isn't a G92 but it has 4 wheel discs... they were also a part of the WS6 option.....yet 92GTAs car doesn't have them...strange.

 

From my understanding you could not get rear disks with the 305/auto combo. When the buyer of my GTA ordered it with the 305 then deleted the 5-spd and ordered the auto the rear disk were deleted and he said he could not order them at time either. This was also in the early 92 model year too when they were having problems with the rear disks so that might be why in my GTA's case.....

 

Sorry guys, forgot that pontiac didn't use the G92 code. My mistake.

 

Actually Pontiac DID use RPO G92 as an option group or an indiviual option if you deleted what it usually came with, it later became part of the R6P option group though.....

If my GTA had the standard 5-spd it would have R6P option group with the G92, N10, etc......

 

240HP for 92 GTA.

 

Since you're asking about a 92 T/A and L98 I'll assume you're asking about that combo. For 92 the L98 required dual cats and rear discs, the only exceptions were if the car falls in with the group that had the discs deleted. The HP specs for pretty much every L98 Pontiac 88-up from what I've seen are very questionable. Having worked with both the Camaro and Firebird I can't see any reason why the L98 in the Camaro would really have any more power than the same engine int he Firebird. My conclusion is that GM skewed the numbers for their own marketing reasons the same as they have been doing since the 60's.

 

Thanks a lot for all the info guys! I really appreciate it!

The intake for the camaro went over the radiator behind the bumper. The Formula/GTA/TA have the ducting that goes around the radiator to a VERY restrictive air canister.

Ok we all agree that the factory horse power numbers are taken from the crank, why would they dyno the engines with different intakes? Besides that the Camaro intake has one advantage over the Firebird in the intake system, and thats the place where it picks up air. Both intake ducting setups are equally restrictive. Look at a camaro airbox before the air silencers are removed and tell me thats not more restrictive then the 3" round opening on 88-92 Firebirds. The intake ducting is only a reasonable argument for 85-87 TPI firebirds since their system was totally whacked in the head.

 

The camaro picks up cool fresh air from behind the bumper. The Firebird gets warm air from the engine compartment. The opening in the canister is not very big either.

The engines have to be dynoed as they sit in the car, so the ducts would have to be attached.

Say what u like, both Firebird intakes are more restrictive and not designed as good as the Camaros, and thats what I think made the difference, even if they estimated it. I also agree with the previous post.
