I searched for it and didnt find much..

Anyone done this with a EA82? is it worth doing?

 

And how complicated is it? Is it just the Cap that I need to replace with the 2wd, or with whole disty?

 

Is the power advance noticeable?

 

I gots a hitachi'd EA82

The 2WD to 4WD disty swap is for EA81's - and even for them it has come into question. Skip (I believe) looked it up in the FSM, and the 4WD is actually a better advance curve.

 

But I think on your EA82 they are the same - I don't think there's a difference at all, since the 2WD and 4WD have the same brand of disty....

oh ok... Just thought I'd make sure before I went and bought parts

 

Thanks

Yeah, Skip said he looked it up and they are the same. I dunno, I swapped mine and noticed the difference. Also, Why would someone write that up as a mod if it wasn't?

may be its just me but i swapped my 4wd disty out of the RX and put in a 2wd disty and noticed a difference in acceleration...

 

maybe my 4wd disty had issues too that are hidden and not noticable as well.. who knows..

are you guys talkin about you did swaps in a EA82 and noticed change?

I think Boz is talking EA81, and Meeky said RX - so that's EA82T - both are COMPLETELY different than yours.

 

One thing on the EA81 2WD disty's - they are a different design - made by NipponDenso, and they fail more quickly than the Hitachi's that were used on the 4WD. This failure is due to the shaft bushings. It's not that the bushings of the distys wear at different rates - its that the design of the Hitachi can handle MUCH more slop in the shaft before replacement is needed. Any perceptibale slop in the ND disty will cause dramatic reduction in power, and tach "jump". I've seen Hitachi's that were functioning seemingly perfect with nearly 1/16" of slop in the shaft.
