hey guys i got my ea81 motor running in my Lseries , it was pretty easy i managed to run my larger l series flywheel and clutch over the smaller ea81 setup. with a little bit of filing on the bottom section of the motor. (the smaller ea81 clutch disc wont mate to the larger spline of the L 5speed, i have herd about using a gemini 1.6l petrol disc but ive never tried it)
Had to run a new trigger wire to the fuel pump due to changing to the old dist. setup. as i couldnt figure out where it was getting its source from. left the engine loom on the motor and joined it into the L's one. throttle cable mated up okay , engine mounts lined up nicely. just hooked up the fuel line and not the return yet , might run a t-piece with the return if i fine the pump overpowering the carby. ea81 long water pipe fits up well , but the lower one would be best if you found and pipe that fits well i made the ea81 fit.

now i have a motor i can adjust the tappets on instead of the dreaded hydro tappets and cracking oil pump seals of the ea82.
cheers brenton

Good achievement, a lot of people ask whether it can be done or not.

Sounds good... Interested to know... It would show a power gain than EA82?

I don't think the EA81 is more powerful than the EA82 - if they weren't the same to start with (but I'm pretty sure the EA82 had *slighty* more kw than the EA81).

The EA81 would be a great setup in an L I reckon - at least you couldn't possibly throw a cam belt while offroading

This is just from the top of my head, so I could be wrong, but it is something like this:

EA81 - 59kW
EA82 - 66kw with leaded petrol (So 1985)
EA82 - 61kw with unleaded petrol

Not really that much difference (All carb models of course!).

Fitting the EA81 could be a lot less problematic for almost the same power.

I thought it was 63kw in all EA82 carby models?
EFI EA82 was 70kw?
Turbo EA82 was 83kw?

EA81 81kw?

EA81 Carby was 73Hp or 55kW
EA82 Carby is 84Hp or 63kW
EA82 MPFI is 94Hp or 70kW
EA82T is 115Hp or 86Kw

yeah i didnt put the motor in for more power , i wanted to be able to adjust the tappets and have a bulletproof motor for off roading (less things that can break) . the motor has enough power to drive my 28" tyres atm. its just a much easier motor allround to work on. i changed the dist. to a electronic 2wd ea82 one to get rid of the points and allow me to run the Lseries wiring. id say its a good conversion if you have a ea81 laying around and a shot ea82. emissions might be a prob with the rta tho.
