Ecotec RWD 5 speed manual gearbox (found one!)

Postby CancerWagon » 02 Nov 2006, 01:52

Thanks again to wikipedia and a little further research, I have found a currently in production RWD gearbox that will attach to an ecotec platform engine :D

GM part # 12580064
Found in: pontiac soltice roadster, canyon/colarado pickup lorrys.
Costs: $1000 - $1300 spanking new at your local dealer

I'm going to go find a soltice at a local dealer this weekish and get a look at the Ecotec oil sump, as there is a chance it may be compatible to work around a chevette chassis :D

I've seen crinkled cavaliers in scrapyards with ecotecs, but have yet to see any of thoes lorries in the same perdicament... but I'll be checking!

Hey mate. I'm actually doing exactly the same thing at the moment! I'm trying to get the sump off so I can measure it up against the earlier model singlecam 8v astra/vectra motors.

My sump has the bowl at the front of the motor (cambelt end) while the one I'm after has the bowl at the rear (gearbox end) making it suitable for a rwd application. I was hoping the ecotec sump woulf work but no such luck.

I've also found a gearbox to suit. I assume you wouldn't have got them there but we have a car called a Holden Commodore and the VN model came out with a 4 cylinder engine similar to the 8v I spoke about up there. I have measured the bellhousings and they seem identical. The commodore may have been realised elsewhere as Chevvy Luminar (sp?) Vauxhall/Opel Omega etc etc. The sump off these is still a forward bowl though so it won't work in a chevette.

My daily driver is a FWD cavalier with a ecotec, and it has the forward bowl. :evil: I'm HOPING the RWD ecotecs, (soltice etc.) have a different sump.

There was a "Lumina" around here but it was FWD. The domestic NA auto market is most all FWD since the beginning of the 90s. With a few exceptions.
Sadly there are plenty of really nifty vehicles GM won't bring to north america, holdens inclusive. A whole line of really great stuff... that seem to only exist in south america.

My end goal is to eventually build up a chevette, using more modern technology. However, also keeping the overall car to look stock. It's actually pretty hard to find a basic 'no frills' auto now. My "base model" modern car is "loaded" according to 1978 standards. :?

cadillac catera gearbox should hang off the bottom of a ecotec engine for all you north americans as this was just a badge engineered vauxhall omega with the 3.0 v6 vauxhall ecotec engine which has the same bolt pattern as the 4 cylinder! hope this is of some use! :D

we mostly use the getrag 240 gearbox and the sump of a Opel Manta 1,8S, which has a 1,8 OHC engine, to fit a DOHC to a chevette or kadett c.

gearbox is the same as from a opel rekord 1,8S.
but i'm afraid, there will be no such car in canada or new zealand... :?

I remember the catera... has a little yellow duck as a mascot. Not sure if they only had automatic gearboxes or not.

Also useful info for finding a V6 for my cavalier, without ditching the gearbox. :D

Can anyone find or lookup a part# :?:

The local stealerships have no clue what I'm talking about and can't look them up. However supplied a part# they can get most anything.... often not knowing what it is untill it arrives, unless I tell 'em. :lol:

my EPC doesnt include mantas. TJM can get you a sump to fit the XE for RWD conversions - this will fit the ecotec family of big block 16v engines.

Yeah well I guess you just have to be carefull on where the oil pump is sitting. I was going to convert my ecotec to rear sump but found a dirty great oil pump hanging out the bottom, effectively meaning I can no longer use the engine. Single cam block with ecotec head it is for me then. No doubt that will raise yet more issues. Damn I hate cars.

unsure what the single cam block is like over there but over here its essentially the same as the 16v block with a few minor differences. oil pump location is the same(cam belt side of the engine)

as i say maybe there are differences over there. i can show you pics of what they are like here if you wish to see them

I'm starting to agree that the engine was not designed for a RWD application. The solstice I got a look at, has the frame designed around the same sump as my FWD 05 interceptor.

(the following may be an incredibly stupid idea, the possibility of completely srewing over the steering geometry is incredibly high, but will never know for sure untill I try it, and not have a conclusive answer for probably a year)

Armed with a pair of chevette diesels I'm picking up in the next few weeks, (disposable rotted chassis or two) I'm going to reasearch (experiment) the possibility of modifying the crossmember/steering to go around a ecotec engine. IE: reversing the wheel hub assemblies right to left and moving the rack and pinion rearward, rebuilding the crossmember to support the new rack position.

"BUT THE STEERING WILL BE BACKWARDS!" I hear people cry... flipping a rack upside down will correct that, but place the linkage on a RHD position.... what if I flip a vauxall rack upside down? :twisted:

Yeap, they probably are the same. But by '16v' I'm assuming you mean the red top c20xe, which is different to the ecotec. The ecotecs oil pump is burried deep within the sump on FWD Opel Vectra B's. There are other models which came with a suitable rear sump, but I'm yet to find evidence of their existance.

Regardless of these facts, I'm worried that the GM Ecotec that I'm guessing cancer wagon is using differs from the opel/vauxhall ecotec that I will be using. I know they look very different in the pictures I have seen but I haven't looked at the specs of the GM ecotec. And yes I know they were all made by GM, I'm just using the names that they are commonly refered to as.

This is the ecotec 2200cc engine I'm refering to, has a internal chain drive for the cams:

Yeap, thats what I was meaning. In the states the ecotec is the GM engine, where as everywhere else in the world when talking about the ecotec engine people assume you are meaning the vauxhall/opel/holden model, which seems to be a similar motor and is available in many sizes.

I can't find a decent pic, but this is a 2.2L ecotec from the other markets. Its cams are belt driven and you can see there are many differences, although I'm not sure how many similarities there are as we don't have the GM ecotec over here.
