Default "LS" engines: Where did the "LS" designation come from?

Does Honda call this engine "LS"? Or is the term something made up by end-users?

I did search, both on this site and elsewhere.

LS comes from the LS model Integra.
LS was the Luxury Sport

Integra LS: (luxery sport) Came with power door locks, sun roof, power windows, Has ABS, The LS also came with cloth seats

The engine is called LS because it came out of the LS integra

Yea it's named after the LS model, I never understood why since it's used in all trims, GS RS etc.

Actually every model LS GS RS etc. all came with the same possible options from the factory, so you can't really distinguish a model by what it has. Just food for thought.

I find that a bit puzzling. My understanding is that all North-American Integras were sold with the B-series engine regardless of the car's trim level.

I got my info from the FAQ:


Integra RS: No abs, No moon roof, power windows,power door locks are an option, came with cloth seats

Integra LS: (luxery sport) Came with power door locks, sun roof, power windows, Has ABS, The LS also came with cloth seats

Integra SE (special edition): (only available in 1995/1996 which is basically the integra GSR without the suspension and engine upgrades) Comes standard with leather, moon roof and all power options

Integra GSgrand sport) the "twin" of the SE but wasn't released until 1997.. Basically the GSR without the engine & suspension (comes standward with all power options and moon roof)

Integra GSR: Moon roof, all power options,In earlier years of GSR's leather was optional, after 1999 leather came standard.. They also came with DOHC VTEC engine


But, you are right.

'97-'00 Integra Type R - B18C5 1797 10.6:1 195hp@8000RPM/130lb-ft@7500

'94-'00 Integra GS-R - B18C1 1797 10.0:1 170hp@7600RPM/128lb-ft@6200

'94-'00 Integra LS/RS/GS - B18B1 1834 9.2:1 142hp@6300RPM/127lb-ft@5200

They all have the B18B1, but I'm GUESSING that the LS is the most common so people just refer to it as that?

Prime example above, his is an LS with no sun roof or power windows or locks, when my LS has them.

Everything that you have listed from the FAQ were all options for ANY trim level. And I get my information from someone that was a salesman for acura late 80's early 90's. And many other people.

correct. excluding the 1st gen tegs.

"LS engine" is just a generic phrase used to describe all b18a/b engines

We use LS as a generic term because LS were by far the most common non-VTEC trim level of Integra in the US.

ls is a b-series, but the pre-90 integras had a dohc d-series.
