Hey Firebug, thanks for the great comments.

There's no problems holding up to the power of an eg33, piece of cake. I would recommend the Subaru turbo box from 2000 onwards (the 8 bolt bellhousing). They will bolt straight up to your eg33 and include all the goodies such as wider gears, double synchros, revised oil paths and so on. Take a look at my website http://www.subarugears.com on the fully built transmissions page. I have a table where you can match up your engine/hp and vehicle weight and see what transmission we recommend.

Of course you don't have to purchase an entire reversed transmission from me, you can just get the r&p and your own transmission and do the mods.

P.s. I am located in Sydney, Australia. All my components are priced to include worldwide shipping to your door so don't let my location scare you. Complete transmissions are around $400 shipping to your door, a little cheaper if they take the slow boat.

4.86 ratio is feasible, I've got the engineers working on it right now to see if we can fit the teeth in that size housing. Close ratio gear sets are available too. Take a look at the reference page on my website, it lists all the gear ratio sets available in Subaru transmissions, so you can pick and choose.

Not sure I understand your statement 'I hope you can do this and gain lots of strength and save the expense of buying the adapter'. Also what do you mean by torsional input shaft?


I would like to see something to be competitive with the built VW 091. Torional input shaft twist a little to absorb harshness so as to prevent some damage to the tranny.
I am thinking of the suby tranny as an alternative to be used in mid engine configuration for those of us choosing Suby power plants. Mid engine in a Woodsbuggy currently consist of mostly adapting to Chevrolet power-glide with separate differential ,,,and there is a Honda coupled to an Audi automatic thansaxle,,or maybe it is a Mendola,,,not sure :? . If I could put a suby tranny on my eg33, run it mid engine it would need to be very strong to justify itself.

I'm glad Todd is on the site, I emailed him with so many questions about these gears that couldnt even begin to recall all of them. I was thinking about the cost of the gear set and right now it seems very affordable. Between all the costs of doing the suby swap with a beefed up vw trans, It seems like the right way to go. I was more worried about the durability in the woods where we ride. I figured the costs as far as a good 6 rib would be around 2000 built with all the good stuff, adaptor 500, high tourqe starter250 and clutch 100+. it seems like the way to go. All wee need is a test subject! :wink:

Thanks for explaining about what you meant with regards to torsional twist on the input shaft. Let's not second guess the results of 5,863,639 Subaru transmissions on the road (or however many they have sold). Whatever twist is built into them is correct.

These manual transmissions are the stock transmissions supplied with EG33 powered cars in every market around the world except the U.S. where you got the auto only. So it's perfectly matched to the EG33 and will laugh at it's power, especially in a light buggy. The EG33 only puts out 230hp. Even the 2 litre 4 cyl EJ20T STi puts out 265hp and they have the same manual gearbox.

I say much better than a mismatched vw 6 rib Kombi or 915/G50 which is old/huge. But I'm biased.

I'm sure you'll have someone build a test one over there soon. In the meantime hopefully we can prove its worth a bit with our test buggy on some trails and dunes over here.

I want to see the test results on your buggy before I order a set. I just bought a whole suby with a 5 speed just for the tranny and motor

Theres almost a new ecotec build on here every other week. Where I ride this year alone there was 3 new ones built and now many more have scene the results and are jumpin on the band wagon. I got my last 2 adapter plates from Kennedy Engineering. One was $550 the other was $450. Was wondering what it would cost to make and adapter plate or if its even possible. Sounds like a good money save on trans but sucks they arent available in the us.

I might have two 6 ribs for sale to fund my suby trans lol


Awesome info! Loving this thread.

Hey guys that's great news that there are lots of Ecotec builds. I really need you to be specific though as 'Ecotec' is a very generic term. Here in Australia it refers to the Buick/GM V6 3.8 litre pushrod motor that was used in our local cars for a long time. I'm sure as heck you don't mean that lump of crap.

I did some googling and it seems there are some different 4 cyl ecotec motors out there. Are you using the stock turbo ones or n/a ones or what? I believe some of them have different bellhousings to some others.

If someone is THE authority on U.S.A. ecotecs please post detailed info (and even better detailed photos and measurements) and we can get to work. Might even be able to modify a Kennedy one.

er....yeah that doesn't actually give enough detail for anyone to do anything with. All of those cars are available in the USA but nowhere else. Need details on the actual engines and bellhousings, some sort of drawing of the bellhousing would be a good start, then an adaptor plate could be made. Or the actual engine type identification so we could see if a similar one is available down under to take measurements off.

HI, Here are some 2.2 bell housing dim.

I think the bell housing are the same for n/a, turbo and supercharged. The flywheels do have different amount of bolt holes thought.

Maybe it will help

Hi ttriebler,
The dim. on the drawing have not been checked by me. It looks the same as my ecotec 2.2 engine.
I found this print when I was researching about putting an Ecotec in my buggy about 8 mo. ago.
It was a guy that was making his own adaptor for a 2.2 Ecotec and a rear wheel drive car.
So I copy it just in case I would like to make my own for my buggy.
I end up buying a Kenndy setup. Real nice stuff.
I have been looking around trying to locate the web site again but not having any luck finding it.

Just wanting you to know before you put alot of work into it.
Norm
