There was no TurboII in 1985. Just the S, GS, AND GSL which came with the 12A engine. The GSL-SE was the top of the line trim level and came with the 13B fuel injected engine. All were naturally aspirated and all used the BR8EQ-14 spark plugs. The SE's fuel injectors were the same part number and the SE only used two fuel injectors whereas the 86-91 RX-7's had two primary and two secondary fuel injectors.

The T2 was introduced in 1986 as an 87 model year car and ran through 1991. The FC used different spark plugs from the S3. They were NGK as well but different heat ranges were used for the leading and trailing spark plugs. They were BR7ET and BR9ET if I remember correctly.

welcome to the board.

as mentioned above, we seem to have a wire crossed somewhere .... your car is either not an '85 or it's not a T2. i guess maybe it could be an '85 with a T2 engine swap??? if you look at the banner at the top of this page, does it look like the first car or the car in the middle?

at any rate, you don't need to buy injectors unless they are known to be bad or missing. you can send them somewhere to get cleaned/refurbished and flowed, then just re-install and go.

if it's a case where you need to replace them, then:

the GSL-SE used 680 cc, low-impedance injectors with a Bosch EV1 connector. i've read where some came with 720s, and i'd imagine they would also be low impedance as well. i would also imagine color might be the only way to distinguish between them, from the outside.

the T2 used 550 cc injectors, but the S4 cars were low impedance with the EV1 connectors and the S5 cars were high impedance with Denso connectors. as i understand it, there was also a weird transition injector (still 550, but connector and impedance differed) in 1988, it's no big deal really, but first let's see what car you're actually getting.

I'm fairly certain the confusion stems from Gran Turismo 4. In it, there's a Savanna RX-7 GT-Limited listed as '85. Due to it being a bit difficult to localize for North America when it comes to Japanese Market vehicles and reliable information being a bit iffy at the time, they went with the production date which began in September 1985 per Japanese tradition. In most cases, this "rolling back a year" works since Japan typically received new models one year before North America. A good example of this is the FD, which entered production October 1991. That puts it right in the middle of the 1992 Model Year, yet the North American version is branded as a 1993 model. The CA series Mitsubishi Mirage/Lancer got the same treatment. '92 for Japan, '93 for North America.

that’s why I sat silent. It may be an rhd 85 fc t2.
