1993-
4th
gens
F-cars are introduced sporting an all new look from an all new
car. The only
motors that are available in the new F-cars are the 3.4 Liter V6 which
replaced
the 3.1 and the LT1 which replaced the three V8 choices third gen
buyers had, L98, LB9 and L03. The LT1 is still a SBC, how
ever it is very different from the predecessors it replaced. The LT1
has a reverse
flow cooling system, cooling the aluminum heads first allowing for a
healthy 10.4:1 compression ratio. Also the LT1
has an optical distributor mounted on the front of the motor under the
new cam driven
water pump. The engine management is similar to the ones
used in 90-92 era TPI cars, a speed density system with a removal PROM
chip. The trans choice for auto buyers is a 4L60, which is a
700R4 with a different case connector and extra check ball in the valve
body.
Six speed buyers in the Trans Am got a M29 wide ratio Borg Warner T56
standard, with 3.23 gears. Z28 and Formula buyers how ever could get
either the M29 or a different M28 Borg Warner T56 which came with 2.73
gears. The rear end is the GM Corporate 7.5 inch 10 Bolt, still a solid
rear axle
in the new 4th gens with a rear suspension unchanged from third gen era
cars. Major changes were
made to the 4th gens front suspension how ever. The 1993 Camaro was the
pace car
for the Daytona 500, Chevy built 650 special edition pace cars. SLP was
also turning Firehawk edition Firebirds, which saw a slew of
modifications to the suspension and brakes as well as a specific hood,
this again was only available on Formula models.
1994-
GM
made
several
changes
in 94 as it began phasing LT1s in the B-body line,
the cars were using now a PCM. With PCM the computer controlled the
trans
as well as the engine. In Autos it meant a 4L60E which was computer
controlled,
in the newly geared for 94 six speeds it meant CAGS, a 1st to 4th lock
out under partial throttle. There would be only one T56 option for
1994. Engine Management was now Mass Air Flow. Along
with the new system came new fuel rails, the cross over tube now on the
front, these new rails housed 24lb Injectors. The standard rear
gearing
for the six speed would be 3.42s to better suit its new internal gear
ratios.
1994 marked the 25th Aniv of the Trans Am, a special commemorative
model
was on option for TA buyers. It featured white leather seats, white
exterior,
white wheels and a blue stripe. Other wise it was the same as a Trans
Am
GT. The Trans Am GT option of course was a Trans Am with 3.23 gears for
the auto, 3.42s for the manual, Z rated tires, high level spoiler and a
155mph speedo. Z28s got new white lettering on their gauges but the car
remain unchanged cosmetically other wise. The convertible was also back
for 1994.
1996- 96 marked many things, for one OBDII which entailed dual cats, crank postion sensor and a new PCM. GM raised the HP rating to 285 for this year. GM introduced two new performance options, the WS6 package for your Formula or Trans Am and the SS package for your Camaro. SLP built these to performance options, the package added a Ram Air intake system, Freer flowing exhaust, Higher rate front springs (360lbs/in) Variable rate rear springs (130-180Lbs/in), Stiffer front and rear shocks, Harder 1lE bushings, Larger diameter front anti sway bar (1LE 32mm), Increased cooling, 17inch wheels with 275/40ZR17 tires.
1997-
This
would
be
the
last year for the LT1, in 96 GM dropped the B-Body,
turning
the Arlington plant in to a truck assembly plant and in 97 GM would
unveil
the new C5 with the LS1 V8 Gen III Small block Chevy. How ever changes
were made, Camaros got a new tail lamps, new interior, with a
redesigned dash and console.
All F-bodies now had digital odometers and trips. The 97 interiors
would
carry in to the LS1 cars to the end in 02. 97 marked the 30th Aniv for
Camaros, so GM made a commemorative Z28 with white exterior and hugger
orange strips, the car also featured white wheels and white leather
seats.
SLP decided 110 select Camaros and 30 hawks would get the 96 Corvette
LT4.
The LT4 was a factory modified LT1, with better revamped LT4 heads, LT4
intake manifold, LT4 fuel rails, 1.6 Rockers, better starter, revised
exhaust
manifolds and a few internal modifications.
