the t/a's came with a better suspension, more interior options like power stuff, ground effects, different tail lights, different rims, different hood and fenders. their pretty much the same just with more options. hope that helps.

the gta's were fully optioned, they had power everything, ground effects, luxury interior, t-tops on most of them, gta rims, v-8 engine standered. the formulas had the 350s in them, basicly a bird that had all the options as a t/a just without the body looking like a t/a.

The Firehawk was a Formula that SLP took and heavily modified the engine, put a ZF 6-speed from the Corvette, dual/dual exhaust, T-ram intake, and the Ronal wheels.

Basically the breakdown is this.

Base Firebird: V6 or TBI V8, could have all the options that was on a T/A except the WS6 and the TPI motors.

Formula: Base Firebird body with either 305 TBI, 305 TPI or 350 TPI. Standard was the WS6 suspension and 16" wheels. Everything else was optional on the car, including the GTA style ultima seats and deluxe door panels. The Formula was the only car in '91 and '92 that a person could get a 350 with T-tops.

T/A: Base Firebird with a 305 or 350 TPI. Could be stripped with no power options or be fully loaded with everything that also comes on the GTA. 305 TPI could be either manual or auto, 350 TPI was auto only. T-tops were not available on the 350 cars in '91 and '92.

GTA: Top of the line 'luxury' version of the Trans Am. Every option came on the car, the only option you could order was t-tops, but not on the 350 cars starting in 1991

A Firehawk was a super-low production Formula that was basically made into a street legal race car by a company called SLP. Some had cages, upgraded brakes, Ronal 17" wheels, T-Ram intake, Corvette transmission, and a bunch of other mods. They made 4th gen Firehawks, as well, and in much greater numbers.

The TAs and GTAs have the same GFX, which differs from that of base birds. Maybe that's a better way to word it.

looks like a base bird with formula rims and hood...or could be base formula with the rear hatch changed...but the firebird fender emblems lead me to believe it is a base bird

SOME of the early 87 Formulas may have had the "Firebird" emblem on the fenders, The reason I speculate this is in some of the early literature they have the Firebird emblem attached, then the "Formula" decal on the doors as well.

Looking at the picture I really can't tell, which way the car was converted, either it is a Base firebird with a Formula hood & Wheels, or its a Formula with a base wing, either way something has been changed.

OK, here it is. The car is a 1987. It has Formula Hood, 16 inch wheels, and WS6 plaque on dashpad. The car has NO RUST. When I took the carpet out the floorboards looked brand new. The front fenders are a little out of line. The rear hatch is off a 1986. The engine is a mystery. Anywhere you would normally find a casting number there are none. I have no idea what size engine is in it. The vIN list a base model Firebird. I belive it was in an accident and the donor car was a 1986 Formula. Sound logical?

not actyally, since there were no 1986 Formulas.

What are the last numbers in your VIN, it may be an early Formula that got the 86 hatch, I have never seen this however.

The mystery may soon come to end. The car before I brought it was registered it whole life in Powhatan Va. There is a weekly newspaper and they will do short article on car mystery. Would not work in large city, but I guess more interesting then billy bob losing 2 hunting dogs. LOL

Actually also incorrect, the '91-'92 Firebirds had the exact same GFX as the Trans Am's and GTA's. Only the Aerowing and taillights were different. Also the GFX on the '90 Firebirds were also the same as the T/A's and GTAs

THe base hood on the base firebirds were also unchanged, Cosmetically the differences between the Firebirds with ground effects and the trans am with GFX are the following:
1) Trans Am & GTA got 16" rims (standard) - 88 or 89 & up
2) Trans AM & GTA got special louvered hood - 85 & up
3) Trans Am & GTA got aero wing (standard) - 87 & up.
