LS1
A V8 built by General Motors. Ricers call it old-fashioned because it is a pushrod engine, however, they completely ignore the coil-per-cylinder distributorless ignition, plastic intake manifold, and aluminum block and cylinder head.
This engine was found in all Corvettes built from 1997 to 2001, and in all 2004 Pontiac GTOs.

It has evn higher performing variants, like the LS6 which features a more aggressive camshaft profile and higher flowing ports, the LS2 which displaces 6.0L and has displacement on demand, and the LS7 which is 7.0L in size and features CNC ported cylindr heads.
The LS1 is featured in many high performance vehicles by General Motors.

A person that overcomes the factory limitations of their vehcile to gain more power, lower times at races, and/or better handling.

When emmissions standards were introduced, many tuners gave up, but others learned about HC, CO, NOx, CO2 and were able to improve those numbers.

When electronic controls were introduced, many other tuners gave up. but others learned the way they worked, and were able to make performance gains in their cars.

What stands in the way of tuners now, is quite frequently, illogical laws that ban tuning outright, despite the fact that a well tuned engine can have lower HC, CO, NOx, CO2 and fuel consumption than one in factory specification. The same goes for swaps, even though the emmissions of a S15 SR20DET are less than a 1989 KA24E, many areas have laws that declare the Silvia Conversion illegal anyway. If you think that Japanese cars are the only ones affected, think again. Many Chevy guys have fitted LS1/LS6 and LT1/LT4 engines to older cars, bringing lower emmissions and fuel consumption in the process. European imports are also affected, as a popular swap is to take a 1.8 turbocharged engine from a VW MKIV chassis, and fit it to a MKII Golf or GTI. Still, many areas have laws written by people who don't know any automotive physics.
Any car with altered factory parts, fabricated parts, or specialty aftermarket parts is considered a tuner car.

Any driver who builds or installs those parts is a tuner. Tuners also adjust things like the mixture screws on a carb, or the programming of EFI.

Cars that used to be more reliable than domestic builders in the 1970s, 1980s, and part of the 1990s. However, they have assumed that they can build good cars by divine right, and have made many problematic vehicles. One such example is the poor PCV system found on their 3.0L V6. They are also convinced that only an idiot can have a warranty problem with one of their cars, and if you do, prepare for a fight.
My mother had an oil leak from her 2002 Solara. For 1 hour and 30 minutes, We had to listen to some snobby salesman tell us that Toyotas can't break unless maintained by idiots. Finally the dealership mechanic pointed out the oil leak, and the rude salesman didn't even make an attempt at an apology.

The manufacturer that is making new domestic drivers everyday.

LS6
Later versions were variants of the LS1. The LS6 featured redisigned cylinderheads, a new plastic intake manifold, and a camshaft with increased lift and duration. Some also featured titanium valves. The factory horsepower rating was 385HP on some ZO6 Corvettes, and later models were rated at 405HP. However, testing has shown that the real output of the engines are higher than their factory ratings.
The LS6 is found in Z06 Corvettes built between 2002 and 2004.

LT4
A higher performance version of the LT1, the LT4 featured improved cylinder head design, a specially designed intake manifold, and a camshaft with increased lift and duration. The factory horsepower rating is 330HP, however, many believe the true power is greater than that.
The LT4 is found on the 1996 Corvette Gran Sport.

A vehicle manufacturer similar to Toyota, which built reliable vehicles in the 1970s, 1980s, and 1990s, but, like Toyota, has made a few duds in the last few years. They are also convinced that their vehicles can't be broken unless driven and maintained by idiots.

While a number of Hondas have given the driver years of trouble-free operation, the ones who don't get one are in for a world of pain.
My mother had a 1999 Honda CRV. The Air Conditioner broke 3 times before the car was 3 years old. Each time, the dealer become more angry at us, and wanted to get rid of us.

A luxury import car by Nissan that tries to introduce innovations before other manufacturers, and sacrifices relibility in the process.
A car by Nissan that has a good engine and transmission, but all other systems are in doubt.
My mother had a 1985 Nissan Maxima, and in the nine years she had it, the A/C compressor broke 3 times, the alternator broke 3 times, and the battery had to be replaced once a year. She had friends with 1986, 1987, and 1988 Maximas, and they had similar problems.
