I've done the 5spd D/R swap into my EA81 Hatch, used the EA82 flywheel. If you've done this you know the timeing marks are off now. My question is, can I just find TDC and put a notch on the flywheel and use that to set my timeing???? Anyone else done this???? Thanks, Tim

Shoot Archemitis a PM. He's re-marked timing marks before on many a flywheel. I"m sure he can help.

Cool, I will:) Tim

I use the marks on the ea82 flywheel on my Brat... I think it depends on what body the flywheel came from.....

I know this doesn't have anything to do with your question, but did you have to use a shortened EA82 Driveshaft to do the swap in your hatch, or is there another option?

I had the one piece lenghtened 9". Tim

Mine is from an XT. Tim

as far as i can tell that should work perfect. its funny, the timing holes on the ea81 compared to the ea82 are very far apart, but whenever i remark an ea81 flywheel for the ea82 engine, the tdc marks only end up about 15 degrees apart. miles fox confirmed this when he was up here last year.

 

then only thing that i would worry about is the initial timing of the disty. if your disty sits at 15 degrees advance at rest and you point the rotor dead on at 1, then you will be marking a 15degrees advanced mark. im pretty sure the rotors dont just sit at 0degrees.

 

maybe i can just measure my ea81 flywheel marked for the ea82 and tell you how far apart they are.

You need a tool that screws into the #1 spark plug hole that will stop the piston as you carefully turn the engine over by hand. I have made this tool for small block chevy engines. I hollowed out a spark plug, taped the inside, threaded a bolt with jamb nut through. You set the depth of this bolt to stop the piston before TDC, mark the flywheel were the pointer is on the bell housing. Carfully turn the engine backwards till the piston contacts the bolt, mark the flywheel at bell housing mark. Measure the distance between these marks and divide by two, that gives you true TDC.

thats scary, use a plastic straw, or plastic bic pen body if your gonna try that. but im about to measure mine for ya.

 

mcbrat, they are so close, what if your are a few degrees off because of this?

just a thought

You have to have somthing to STOP the piston before TDC or your two marks are going to be in the same place. You can by this tool. It is not a "shade tree" method. Also I said twice, to CAREFULLY turn the engine over. If your not competent enough to CAREFULLY performe this task buy all means don't. You could put a hole in the top of your piston!

hmmm. I had my timing at 10 BTDC according to the ea82 stock flywheel marking while MorganM and I were bombing around the hills at Castana....

 

I'll be dropping a different ea81 into my 87 wagon here shortly, and I can compare to the ea81 ...

ok, i just looked, im runing an ea81 flywheel on the er27, same as ea82, as far as marks go. my 20degree mark is punched at 15degrees.

 

id guess if you ran an ea82 flywheel on an ea81 and went by the marks, youd be runing 5 less degrees of timing, right?

 

i marked mine by sticking the ea82 flywheel on the motor, moved it to 20 btdc, took it off, put on the ea81 flywheel, and punched it where the arrow pointed, which was 15btdc.

I'm going to have to go look at mine. If I remember right, I can't see the EA82 marks at all. 'Course my timeing could be way off too, just runs to nice for me to think so. Tim

Did you have the distributor out? Its possible you are 180 out and therefore have no timing marks showing I think.

Timing is a funny thing.... I've been 180 off and had the engine running. Something to check I spose!

Hey Tim,why not just get a crank pulley off an auto EA81 with the timing marker.I don't know if it was standard on all autos,but my Brat has the crank pulley with timing marker.Just an idea.Dave.

Rick set the dizzy, I just had to move it a tooth. It runs great, but in the persuite of perfecting my Weber carb I want to be able to get the optimale timing out of this thing. I seem to be running out of adjustment to early. I'll look it over tomorrow and see how it looks.

 

Graet idea with the turbo crank pullie. I just PMed you by the way. Tim

i honestly have had only good luck with timing by ear/foot. i time it with a light, then want more. so i just crank it =]

I just hit it with the light, 0º on the fly wheel shows up at 4º on my timeing light. That being said, I don't have a reference point to tell me what true TDC is. So now I'm going to mark the flywheel with a TDC mark and use that as a reference point. Sound about right??? Great discussion on this subject guys. Tim

Okay, this makes sense. What I found to be close to TDC was about -4º. I used the light and if this assumption is correct my timeing was at about 30º advance:eek: . I set the timeing on the 10º advance make, that should actually be 14º. Funny thing it never pinged or rattled like other cars I've driven with way to much advance. After that I re-re-jetted my carb (last re-jet was way to rich). And so the tale continues. Thanks a tonne for the help guys, Tim

i usualy have my advance all the way to that one side =] all my subarus as far as i can remember. they never ping, it just moves the power around.
