I bought my 1990 Rs for $700, it had 190,000 miles on it and ran super strong. It was a 5.0 tbi automatic. I abused that engine and trans for 2 years straight ( racing, burnouts,horrendous over- revving) and it took it like a champ. The engine started to knock at 240,000 and it was replaced with a mildly built 350, and a T5 trans. This car now screams.
I would recommend these cars to anyone that is looking for a cheap, fast, well handling car.
I love everything about this car.
The stock 2.73 rear gear ratio wasn't great. An upgrade to the disk brake posi rear is much better.
I drove a dark red 1988 Iroc-Z in high school. It was the greatest present a man could give to his son. She was strong, fast, powerful, loud and impressive. The 5-speed was matched beautifully to that 5.0 liter. We had a 3.73 rear end with full time posi. She got off the line like no other. I never had any issues at all with her. I damn near cried when I sold her.
Transmission- shifter felt great in the hand, and the long throws made you feel like you were turning the world upside down with all that torque.
Interior space- but it is a muscle car so no big deal.
The stock car has great handling and
power. The interioe is well planned and
the T-tops add the feel of a convertible
without compromising the structural
integrity of the vehicle. Almost
infinite possibilities to make
aftermarket improvements to the engine
Absolute best car for the money. With
the right after market add-ons this car
can run against any foreign or domestic
this unit is super quick, fast and
stong. remember, a poor or moderate
comfort rating is desirable in a
performence car. it has 245 hp and 345
lb/ft of torque in standard form. the
1990-'92 f-body may be the best
performer of all four generations. motor
trend magaine tested this in the march
1990 issue with a 0-60 time of 5.8
seconds. and this test was without
factory option slp. this was a short
model year, so all '90 models were made
during the last three months of 1989.
why so short? g.m. did not renew its
contract with the i.r.o.c. and was not
licensed to use 'iroc' starting january
factory option slp. this two thousand
dollar option adds 50 hp, 50 lb/ft of
torque, and improves 1/4 mile time by
one second. with this option, it will
keep up with the famed 1987 buick gnx. :)
better left without a driver airbag. the
rear end (gears) changed in 1990 from
3.27 to 3.23. this gear change slightly
compromises performance. a larger gas
tank would be better too.
