EOI for ej to ea adaptor plates.

Hi all i'm looking at getting some ej to ea gearbox adaptor plates made up, they will be 12mm laser cut steel, will come drilled for the locator dowels on both motors, and bottom bolt holes which line up on, but only pilot holes for the top bolts so the end user can decide upon the best solution for thier application.

I'm not too sure on cost thus far, obviously the more comittments to buy, the cheaper they will be, i would think that they will come back under $200, but will advise as soon as i know more.

These have been accuratley measured off both an ea82 and an ej20, and a prototype has been fitted up with no issues, however no warantee will be expressed on implied as i am not a shop or an engineer.

If there is interest then i will look at getting a few cut, ifn ot then i will just have my own made.

Mods: As this is just an EOI thread i thought that this would be the appropriate forum to post within, if i'm wrong i apologise.

Cheers, Dan

yeah i could be keen (price depending) but i thouhgt they have to be at ~20-25mm thick...plus some adapter to pust the flywheel out....

I know wheel adaptors can't be more than 25mm thick, i wasn't aware of a requirment for a minimum thickness of gearbox adaptor, will do some research on that.

From my measurements 12mm allows for the ea flywheel to be used with no spacing, which (to my mind anyway) is far more desireable than having to space the flywheel.

no minimum requirement...jsut looking at what others ahve done...

All the commercially available ones i have seen are 12mm thick in either steel or alloy. I have an aversion to using alloy for the simple fact that the 2 top bolts are very close together, and my plan is to thread the plate and screw a stud from each side into the plate so the plate is securely fastened to both the gearbox and the engine, and i am nervous about using alloy in this way. Also cost is a factor, the material cost is higher in the alloy, as well as the machining cost, as the alloy should really be cut on a waterjet which costs more than a laser. Irregardless i am planning on talking to a LVVTA certifier befoere i get them made.

Cheers

definatly interested. price depending tho

Hi mate, just worked out why the extra thickness, i'd lay dollars to donuts that the conversion using that setup was using an adapter plate to match the bolt holes in the ea flywheel with those in the ej crank. I will be redrilling my flywheel to the correct pattern, probably with a mill and rotary table, or i'll make a jig up to use a rotabroach to cut the new holes.

cheers.

will it work the other way too

EJ gearbox to ea engine (want to run a proper AWD in the rx)

lol. im tho oppsoise, want to keep the duel range

Yup I intend to as well

I have a gearbox here that is out of an early impreza,AWD and Dual range will have to adapt cv joints but how hard can that be

we choped and swapped cv's from a h22a into a early civic...just welded them up...pretty dodgy but the motor seized b4 the cv's broke!

Theoretically it will work the other way as well, but you might have to clearance around the starter motor, i think the ej type gearbox mounts the starter further out from the centreline of the gearbox, also the flywheel or clutch may be in the wrong plane and might need spacing one way or t'other.

But from a purely 'will it bolt together' angle, i see no reason why not.

mmmmmmm may lookinto it

Right so, i am picking the first adapter up tomorrow (hopefully) so will see how it works out, if people want them i can do them for $190 + shipping, this will get you a laser cut plate with pilot holes drilled for the dowels, and either pilot holes, or tapped for m10 for bolts or studs at the top.

Will confirm the quality and post some pics when i have the first one, and if there are a few people keen will organise the manufacture of more.

Cheers, Dan

wicked am definatly keen

Will these work for ea81 as well?? I am keen as, wanting to run an ej in the brumby. Are these for the turbo ej or non turbo or is there no difference?

yep will work, and no difference i believe.

yup EA81 and EA82 bell housings are the same

and all EJ series motors are the same

sounds good just need to get my hands on a motor and ill be keen for some adapters. are you mass producing or are they made to order

I have a EJ20 longblock here if u want it ( no manifolds)

Picked up the first one today, basically will do them in small batches. The cutting is the easy bit, i need to set up a jig to drill the top mount holes and the dowel holes.

Will post some pictures tomorrow of the first trial fit.

could be but to be honest hav'nt really decided on what way im going go, i'm thinking of trying a supercharger setup but have no idea on how to go about so I'm just reading and learning as much as I can plus the bloody ea is taking all the punishment under the sun and keeps on ticking.....

As promised a picture of the first one.

And sitting on the EA flywheel housing.

I will be making a couple of tweaks if i do more, i need to make up a jig to accurately find the dowel location for both the ea gearbox and the ej motor. Does anyone know if the ej and ea gearboxes have the same size input shaft? For that matter does anyone have a worn out friction plate for either box? Will help with making an accurate jig for the dowel drilling.

The EA81's will for ever and a day

I will be supercharging my brumby

I will use a SC12 which i believe was the ones on the 4agze

I will be running a suck though carby set up ( my brumby already has a webber installed )

Right so a slight change in plan, after measuring a few ej's and ea's it seems that the dowel placement is not identical from one engine to another, thus i can't accurately ream the dowel holes.

I will supply the plates with pilot holes for the top bolts, and the 'ears' tapped to m8 for the ea style pitch stopper, the rod will need to be shortened.

Price will be $190, if people decide that they want the top holes drilled or tapped i can do that.

I should be fitting it up to my motor this weekend, will post some more pictures when it is done.
