EA81 Carby question

Featured Replies

Ok here goes.

 

Someone told me that the carby from an EA81 Sedan has the largest stock jets. Can anyone else verify this?

 

Thanks

All the EA81 carbs *with the same model number* are jetted the same. As far as I know the sedan didn't get anything special that the rest of the cars didn't get. Depends on the year of manufacture, and weather the car was 2WD or 4WD determines which model they got. Besides - a change in jet's isn't going to do sqat for performance on these carbs - the 26mm primary is just too small.

 

Take the jets out and see. It's not hard to do.

its the distys that are quite different. If you can find an electronic disty from a 2wd sedan or hatch, it has a better advance curve to it giving you more power:D I got one in the Brat right now and it runs sooooo much better than the stupid crappy points disty did

what year of car are you lookin for in the 2wd electronic disty? I thought someone said that brats had the best disty's in them from stock. mines an 85, whats the diff?

According to all the research I have done, and Skip did before me, the whole 2WD disty business is a load of crap. The FSM gives only a single advance curve for both types of disty's. There has to date been no solid eveidence of ANY kind presented that I know of to support the supposition that EA81 disty's had different advance curve's on the 2WD's vs. 4WD's. That's not to say that the advance curve's didn't change depending on the year of the EA81 in question, but a thorough examination of all the FSM advance curve listings has not been done due to no single person haveing FSM's for every single year..... at the *least* the situation is a heck of a lot more complicated than just "go get a 2WD disty" as some years are certainly not different across drive trains, and other years might be different, or might be the same but different than a newer or older model.

 

I also have to make a point of noting that the Hitachi distributor's reluctor design is a lot more reliable in that it can handle more shaft slop before going out completely. The ND disty's used in the 2WD's seem to be much more sensitive the shaft slop, and according to my conversations with CCR, are more likely to blow up their ignition moduals as well. Perhaps Subaru used the Hitachi on the 4WD because it is a more rugged design, but was more expensive because of this. I really don't know what the reason for the change was....
