ok so i picked up a 83 t/a today with the cfi motor. im not to well versed in firebirds and the rpo sticker is not in the center console where im used to finding it so how do i figure out what weather or not it has the ws6 package and all that stuff oh and if anyone has any usefull info on keeping the cfi motor running real well (needs a tuneup bad) let me know. any info on these cars would be great.
thanks

 

My '82 had a CFI 305 in it when I bought it. Wasted two seasons trying to polish that turd before I finally upgraded to TPI.

So many things wrong with CFI...first, your hardware is old enough to buy beer now and the bushings are getting worn. Try to keep both TBs balanced. ECM is dog slow and can barely manage fueling and spark curves.

As for your suspension, measure the OD of the front and rear swaybars and then check in the suspension forum.

 

Anybody that says Cross-fire injection is not good, has no clue at all how to work on them. Its amazing how many morons say they are junk, when all they need is the simplest of tuning. Just make sure the TB's are sync'd and you have no vacuum leaks. My 82 TA intake was in the trunk taken apart in a million pieces for 10 years. I put it together, balanced the TB's (you need a water manometer), and it now has a rock solid idle and enough power to run with an L69/5-speed car.

 

I actually got very good at working with CFI, even built my own water manometer so I could precisely balance the TBs. I'm not saying it didn't run nicely, I'm saying it's tougher to make the same power with it than with TPI.

So...borrowing a few words from you...anybody who says they can make good, reliable power with CFI is a moron.

Post your CFI dyno sheet and prove me wrong.
