Yes, I know that they have 4wd and the front differential included, whereas most transmissions have those separate... but, geez, it's just a little car (especially the EA81 and EA82) and it weighs a bit more than the 4 speed from my Mazda truck, or the 5 speed from my Mitsubishi truck, which, theoretically are much heavier vehicles. And that's the EA82 5 speed dual range. The EA81 dual range is even heavier yet. It feels like it's getting close to the whole EA81 engine...

 

A different topic... I'm putting an EA82 SPFI intake and ECU/etc on my EA81, before bolting it back to the 5 speed dual range and putting it in the '82 wagon. Should I also pull the heads and port and polish them? It's sitting on a bench in the nice warm workshop, and this is going to be the easiest time of any to do that...

i've never tought the EA82 manuals were all that heavy? now the automatics...they start getting beefy.

 

i'd think you hit the major points. it's a true 4WD transmission and it includes parts which are typically separate in a truck.

 

trucks have a transmission, transfer case, front and rear differentials, and driveshafts and other mounting components to make that work. i'd guess all of that easily outweights the equivocal functioning aspects of the soob trans.

because they're made of metal?

answer is simple.. the transfer case is intergrated into the transmission.

 

transaxle 2wd cars dont have a transfer case. k take a chevy or a ford transmission and bolt the t-case to it and try to pick it up. weighs more than a sooby tranny

Not that this is the reason but . My at 2.2 tranny is freakin HEAVY! holy crap:eek: and I have a 350 tranny thats half its weight...I presume its just having the additional diff on the front plus the TC...Just concurring that the AT trannys are tanks!

i have determined that the reason why the EA82 5spd Hi/lo case is so heavy is the fact that it is unbreakable

trust me, i´ve tried

Well they have a lot of stuff in them.

 

 

 

 

 

 

 

 

 

And do simple math, alot of force is handled by them too.

 

 

mipper

Because the EA82 5sp has the same size gears/synchros and diff in it as the WRX 5sps. And you know how much power they take? They are a beefy box. Pitty the synchros are cheap and shotty (lucky for me mine are brand new

Some domestic transmissions don't include the bellhousing as part of the transmission, it can be a separate piece.

 

You've got your answer: 4WD, beefy internals, bellhousing included.

 

At least the case is made of aluminum, otherwise...

Yeah.... my GMC shortbus has a cast iron transmission that I'm sure weighs 300lbs or more, even just being a 3 speed.

 

Most transmissions that I've worked with have included bell housings... but I rarely work on american made vehicles or vehicles with more than 4 cylinders either.

ok I'll skip the t-case and whole transmission weight topic and go to the PnP. Porting won't hurt it but don't go ballistic; basic casting flash cleanup is good enough and SKIP the polishing- don't cut back the turbulence as it's good as is and polishing will hurt rather than help so I've been told, unless that is you are going ballistic on your build and trying to get 110+hp.
