79 brat disty to 79 2wd disty, can it be done

[v8vega215]

ok i tried for about six hours last night to put a 2wd car disty in my 79 brat, needless to say it didnt work. i tried to line up the pick-up sensor with the tone ring and number one on top dead center, this all resulted in back fire out the carb and then i tired to retard from there and then it idled fine but the car wouldnt rev past 1100. I continued to try to tune by ear but that wasnt a sucsess. i have read somewhere that one of you guys did this before, any sugestions?

What firing order did you use? It can be done as they are the same mechanically. Just different curves.

i wired it the same as the brat disty 1324, i did get it to idle better than it has ever idled before but it wouldent rev, do i have to change the firing order?

[v8vega215]

do i have to switch the vacuume lines

 

thanks for the bumper about a year ago Q-man (light blue for first gen with skid plate)

Hey, I knew it was you.

 

You may not have the vacuum ported correctly. Or, the vacuum advance may be bad on the new disty.

[Caboobaroo]

yes I would have to agree with qman. Either the vacuum lines are on wrong or the advance is bad. Why would you want to go from a points disty to a points disty? If you can find any EA81 electronic disty ('83-newer), swap that in. You'll get better MPG and better performance. I did a write-up in the USRM about it. I swapped a disty from an '84 2wd car into my '78 Brat and wow, what an improvement!

my distys are both electronic not pionts, but i tried again saturday and this time i capped off the vacuum lines and the result was the same, poping out the carb and a big backfire out the exhaust that almost blew the doors off the brat. i again got it to idle smooth but it wouldnt rev, i found the motor out of my 85 hatch ea81 and it has a good disty in it, would this one be more likley to work.

 

side note: last sunday i went to browns camp with the brat and had an s-10 blazer following me with bfg's. i went through a mud hole that a cr500r couldent get through and the s-10 followed and got stuck. i had to pull him out. we didnt get that on tape but the dude on the bike sure was impressed by the all mighty subaru.

Remember, most 2WDs, with the exception of the automatics. were Nippondenso. The BRAT was Hitachi. The electronics are incompatable unless you switch the control unit too.
