There are probably stupid questions but... How can I tell if my car is TPI or TBI, and what does the RS do for my car. Like how does it differ from the other 89 Camaro models. Thanks.

 

well the rs is only a trim package persay

as for tbi or tpi your car is an 89 in the rs model it should be a tbi


89 RS
Firebird M5,A4 LO3 V8 9.3:1 5.0 (305) 170@4400 255@2400 TBI

 

the tpi will look like this on top of your engine ...








the tbi would look like this on your engine..

 

Ugh, that second picture looks familiar huh general.

 

Thanks guys, but what exactly do you mean by a "trim package."

 

why yes it does...LOL


it stands for rally sport (RS)
in 89 the base model camaro was the RS

 

It used to be, back in the day, the RS package was a couple of spoilers and fancy wheels. Starting in '88 (IIRC) the Camaro came standard with a rear spoiler, cast aluminum wheels, etc. so they (Cheby) just called it the RS. No "base" model, per say.

 

The RS kinda took the place of the SC as the bottom dweller of the camaro.
