When Did The 1st Si Come Out?
Japan & Us?
Trying To Prove Something Here And Cant Find It

 

Here in the US I believe it was the 1986 CRX Si.

 

the first SI was 86....the first SI with VTEC was 92 and it was a single cam...the first SI with DOHC VTEC was 93 del sol....thats all US stuff, Japan i have no clue...

 

cool thanks

 

japan doesnt have Si's, they have SiR's. the first vtec SiR was the 89 CRX SiR with the DOHC VTEC B16A. i think 86 was also the first year for the SiR in japan too with a Civic hatchback with a DOHC ZC motor, not sure though.

 

What does the R stand for in SiR. Anything? I thought I read somewhere, or maybe it was a rumor that SI meant Sport Injection or something. I found it. In an issue of HTM it says it means Sport Injection.

A Classic's Origins

The Civic's roots date back to '73, but it wasn't until 12 years later that U.S. car buyers would have the opportunity to get their hands on the performance icon known as the Si. First offered as a CRX, hatchbacks became available the following year for those desiring four seats.

An acronym for "sport injection," the Si became the first Civic to incorporate a fuel-injected, 1.5-liter powerplant, bidding good-bye to the age of carburetion. Early Si's quickly became synonymous with performance, featuring 14-inch wheels mated to high-performance tires, a monotone paint scheme and sport seats.

 

Canada also had the SIR tag... and our SI tag was your guys' EX. But with the new generation civics it is SI instead of SIR.

 

:slap: Del Sol VTEC wasnt made till 94

 

SI = Sport Injection
SIR = Sport Injection Racing
