EA82T into Brumby?

Green_eyed_liberty · Post by **Green_eyed_liberty** » Thu Aug 05, 2010 7:35 pm

tried doing a quick search.

how much involved to fit an EA82Turbo engine out of an RX leone into a 89 Brumby?

will it bolt up to the 4spd?

what clutch would you use? the 82? or the 81?

been offered one and wondering how hard to fit

cheers

Yes it will bolt to 4spd but its strongly advisable to upgrade to an L series 5spd (this is a great upgrade regardless of upgrading engines).

I can't advise on the clutch if you decide to stick with the 4spd gearbox - I'm not 100% sure on the mix/matching compatibilities between 4spd and 5spd clutches myself.

Physically fitting the engine into the engine bay will require modification (widening) of the chassis rails. I believe you have to modify them even more substantially than you have to when fitting a Quadcam EJ engine due to the shape of the EA82.

Otherwise it should be fairly straight forward, you will most likely need expert assistance when it comes to wiring. It will make a difference if you choose to use aftermarket engine management opposed to the factory ECU and loom. Aftermarket ECU will probably make it easier in this regard.

You will likely need to modify the engine crossmember (cut it and weld in a concave section) to provide clearance for the turbo exhaust manifold.

I did a quick search too.
Here is a thread with someone else asking almost the same question as you;

Here is a thread with some info regarding clutches for 4spd box on EA82 engine;

Another thread about fitting an EA82 into a Brumby;

Hope this helps.

Similar hassle to an EJ conversion and certainly cheaper overall, (that seems like a bargain), but yeah up to you naturally!

For what its worth - Your better off getting EJ22 or EJ series.

I'm going to be in for a rude shock when I fit my EA82T in my standard height Brumby if the above is true, or my EA82 even, for I have seen one in a Brumby in the flesh and no chassis mods - with about 5mm clearance each rail. For those suggesting you go EJ - they are also suggesting you go the EJ box which does not just bolt in either, a modded tail shaft, modded radiator and cooling fans issue. While your EA81 is out, lift out the 4 speed and drop in the L series five speed with minimal hassle and use L two piece tail shaft - along with your EA82T.

SCORE 1 for the EA82 conversion

That's interesting. In this case I'm drawing my knowledge from old Tim81Coupe. I remember checking out his chassis rail mods when he put the EJ20turbo into his old MY coupe and then later, his MY wagon. I remember at one point he was thinking of putting an EA82 into the wagon and I'm pretty sure he actually lowered an EA82 in and discovered the chassis rail clearance was even tighter.
Maybe this only applies if you have a body-lift kit as this would alter the position of the engine. We really need to hear from somebody who has actually done it, or at least someone who has an EA82 and an MY sitting around who could take some measurements.

I consider the chassis rail mod to be a fairly minor one anyway so if I was hell bent on fitting an EA82 this wouldn't phase me any way.

EA82 flywheel and pressure plate
EA81 4 speed clutch plate (9" plate as used in the post 84 brumbys)

I found the thread where Tim posted his findings comparing chassis rail clearance between an EA82 (carby motor) and a Quadcam EJ20G engine. I forgot, he actually did fit the EA82 in that car and ran it for quite some time.

showthread.php?t=5121&

As you can see, he found that the EA82 had alot more clearance issues than the EJ20G, however note that he was running a 3" body lift kit in his MY wagon at the time - which drops the engine down ~3inches in the engine bay.
In the same thread Steve Rising Sun indicates that in an unlifted car, only very minor rail mods are required to fit an EA82 as the clearance.

Maybe it's possible to squeeze it in without mods (in an un-lifted car), but based on the above information I'd say it would be highly likely the engine would bump and rub the engine bay frequently.

It was all this stuff going on back then that was in my mind when I clambered in , under and around a standard height Brumby running EA82T, noting the clearances of about 6mm each side and wondering what all the fuss was about in here. The chassis was not touched, owner had no problems.I felt relieved I was not gonna need to do chassis mods. Also seen close up an EJ20G in standard height Brumby. The chassis was more massaged with a FBH than cut and welded and a tight fit. Tape measure against rails and engines not always best way to compare. One day soon I hope I will have EA82 in my Brumby and will post a few pics of the result.

Either the one you looked at had one of those magical MY's with wider chassis rails or one of those magical EA82s that are narrower, or these other people made the decision to widen their rails for absolutely no reason at all.
Or somebody (on either side of the argument) is mistaken.

Wish I had the parts lying around to find out for sure!

It's the same amount of work to put an efi Ej in as it is to put an efi Ea.
The Ej is worth the extra cost.

No mistake. You need to modify chassis rails to fit an EA82T into an MY.

OK, Jonno is preparing self for rude shock. I have been warned then. Just curious as to what had been done to this signle headlight Brumby I have seen. Can see self knocking on Lees door in coming weeks for a better look - taking the Sony piccy taker too...

It's not a difficult job and if done properly, as you've observed, indistinguishable to the untrained eye.

Mmm, been thinking that may just be the case. The owner did not do the conversion himself

My 2 bits, My Brumby whitch has now been on the road for 2 years now
with EA82 5speed D/R box Had only minor chassis rail massageing done by the previous owner he then gave up on the project.
