EJ EA Swap - Different Clutch Fitment
Posted 11 September 2005 - 02:45 PM
Here it comes I am doing and EJ22 swap into the 85 BRAT as well as a 5 speed D/R tranny. Now the way it has been traditionally done was to get an XT6 flywheel of take and EA82 flywheel machined to XT6 spec, make the said flywheel fit the bolt pattern on the EJ Crank get an XT6 clutch kit and be on your way.
After seening how heavy the XT6 flywheel is I tried to see if there was another way to do this and my question is this: Can any of the following combinations work for my swap?
EJ22 Flywheel - EJ22 clutch disk - EJ22 pressure plate (The spline count is the same on the clutch disk - 24)
EJ22 Flywheel - EJ22 clutch disk - XT6 pressure plate (again the spline count is the same and they are of the same size 225mm)
If any of the above could work it would be TOTALY awsome because:
A) we will not have to remachine flywheels for the swap anymore
we can get lighter flywheels
So yea any input here is appreciated

You should be able to use a redrilled EA82 flywheel with the EA82 disk and PP.
Yes I knew that but the reason I am asking is that I want to use a lighter flywheel for the legacy in this swap.
I have just confirmed that an EJ22 clutch disk will fit the input shaft of the 5 speed D/R tranny is there any other reason then maybe a need to tinker with the starter that i couldnt use and EJ22 flywheel Cluch kit?

What about shaving all the extra weight from the EA82 flywheel? If you're already having a machine shop redrill and balance it, the extra cost to turn off some of the metal shouldn't be tremendous.
Just a thought.

EDIT: ok new idea what about making and extender plate out of alumenum to the crankshaft? All that would be required is a piece of 1" alumenum and a lathe.
EDIT 2: Something like this here you bolt the EJ flywheel to the crank with this piece in between this the starter will now reach it. btw EJ22 starter will fit.
There was an old saying: "if the mountain is not coming to mohamed, mohamed comes to the mountain" or something like that. Thus translating it to this cituation, if we cant get the starter closer to the EJ22 flywheel why not get the flywheel closer to the starter?

i was thinking of trying the same thing since i just bought a light weight flywheel for the legacy, but still want to do the swap to the d/r, if you have success with this, let me know........
If you're off roading, a lighter flywheel is the last thing you want.

how so? a lighter flywheel improves revability and acceleration time, tell me why thats bad for offroading?
Rotating mass of the heavier flywheel keeps the engine rolling better. Several times I've darn near stalled but that massive flywheel kept the powertrain rolling and fired it back up. Like rolling around in 1st 4Lo and not on the gas pedal; that big flywheel will keep you moving.
It's a trade off; not like a heavy flywheel will make you incapable of offroading. If you enjoy the quicker response from the engien VS the heavy rotating mass then go for it. It's upto you, the driver, really.

Its not that you can't use it, myself, i wouldn't.

Yes I am strongly considering steel for this as I wouldn't want the flywheel to come lose at 6000rpms, might even do a couple of calculations there.

The only stopper to this plan is currently the fact that the EJ22 pressure plate is a bit thicker then the EA82 pressure plate (I think not sure though) so still need to make sure that all of that will clear as well as the throughout bearing is the right thickness. Might have to find a different thoughout bearing. That and I have yet to measure the distance from the transmission input shaft to the starter shaft to make sure its the same as in the EJ tranny.
PS does anyone know the step sizes for the EA82 flywheel and the XT6 flywheels?

the EA82/XT6 clutches are not weak...you just have ot search and find the right aftermarket one....I have a clutch that was realitively inexpensive and it holds 240hp/320tq at the crank.
Skip makes lightend flywheels...you cannot take off too much before the structual integrity of the FW is compromised. ~18lbs is as light as you can get it.

just for the record, an XT6 clutch disc and pressure plate can handle whatever power an ER27 can put out, which is probably in the neighborhood of what a EJ22 will put out.
EJ motor clutch disc is bigger in diameter than the EA input splines on the EA trannys, that solves that.
True, the ER27 has more power than the EJ22, so thats a non issue, but the early legacy EJ22, which we are getting our engines from, the tranny spline is exactly the same, verified and checked myself.
