i never knew the twin cams were ever auto?
and yeah hmm not much to tell it was covered in reb backs and such when i went to look at it and now its sitting in storage up bush lol

Well done. Nah i had a twincam and sold it, i actually had to but one was auto, which aren't worth mucking around with as you can't get gearboxes for them (pretty much). Heaps are actually auto. And they seemed to have dried up now that I have sold my one and am looking for another!

Why the fook would anyone want to do that? If its a JR120 chances are its an Aus-delivery once hence no torque tube rear end. Which is abit of a blessing. What you going to do with that one? Have you even got any of your Piazzas running yet? If you do you owe us some pics.

You CAN get boxes for them. Granted they arent on every corner [particularly in your side of the ditch] but its possible to find them. One sollution is to get a C series rodeo bellhousing and bolt a G series SOHC Gearbox to it. Ie. remove the front half/bellhousing off the SOHC box and bolt it to the C series bellhousing. Problem solved.

Really!? That is VERY interesting news. I'm not quite sure if I understand/believe you. haha. So am I confused or are you saying that the bellhousing off a 4zc1 rodeo will bolt up to a g200w?
And, if this is the case, why not use a 4zc1 gearbox? Is the input shaft diameter and clutch facebolt pattern different? I'd assume it would be. I didn't even know g200 boxes had a removable bellhousing.

The internals of the different MSG boxes are more or less the same except for some ratio differences. Providing the shafts are the same diameter and they are both equal in the gear numbers, forur speeds only mate with forur speeds etc., the casing can be taken off one box and used on another. That fixes problems like starters on the wrong side and different clutch actuating setups. There can be some differences like the bolt patterns for the front bearing cover but you'll generally find all the holes are there and threaded where needed even if they were not used.

When pulling apart an MSG box, you secure it in a vise by the rear bearing carrier plate and the front and back covers come off in opposite directions. The complete box internals remain attached to the bearing carrier plate.

Oh I see now. So its a matter of changing the front casing of the gb rather than un-bolting the bellhousing. Sorry I'm kinda new to Isuzu gb's, I'm not sure if your familier with toyotas w and t series, they all unbolt straight from the bellhousing so almost all the gearboxs are interchangable to an extent.
In this case, since its possible to use other gb's in place of a standard g200w one, are there any in particular that are stronger? Maybe a rodeo 2.6 one? And does that trick still work with this? (whats MSG?)

The C series bellhousing is an actual Rodeo Diesel C223 [i *think*] engine for example. Its not a 4ZC1 or E1, but you *might* as Poida said be able to mate this with the DOHC or C series bellhousing. I know for sure that a C series bellhousing mates with the SOHC box.

Yep I agree wuth that. I recently sold a Rodeo G200Z box that was being fitted in a diesel Rodeo with a C series diesel in it. I know the housing was a simple swap in that case.

The way I know of it is this:

4F series, 4Z series and G???Z series are all interchangable with the starter on the drivers side.

C series diesel and G???W series engines are interchangable with the starter on the passenger side of the box.

As far as I am aware you can swap main housings (which include the integrated bellhousing) as per what I said earlier.

Thats perfect. Thats the bit of info I'm after right there. Thanks for that. I was always under the impression that there were no other options.

So I can get a gearbox from a 2.2L (?) Diesel Rodeo? and it should work sweet. Has anyone tried it (input shaft, clutch plate matching etc)?

Is anyone aware if these boxes are remote shifter? Might save me the hassle of changing the g200w box from remote, I don't like it down by the handbrake.

if u don't like the remote shifter i will swap ya for a stocker!!!

hey bradlze how many w's u got?

1 117 coupe g200w
1 race g180w
1 complete parts g180w
1 g180w block
1 g200w still in the car

and a complete jr130 import piazza with g200w and auto just outta reg
and my zz/r sedan

so thats 9 twincams!!!!! sold one early this year so i have had 10

plus the boxes shifters etc

does that make me the twin cam king?????

All the G???W series were that remote shifter as far as I'm aware. The diesel boxes can have a forward mount (same as Gemini) or a column shift setup. These images are of the column shift four speed box behind a C190 diesel engine.

I'm seriously contemplating using one of my spare G161Z engines with a five speed box and this column remote linkage gear in my 1975 Totota Hilux tray. At least getting bits will be a pinch with the Isuzu engine and box in place of the 12R and it's half bell housing abortion of an idea four speed box. Can't get a five speed to fit and it revs it's tits off at 100km/h. I drove to Bundy and back in it and that was enough. Be way quieter, more comfortable and probably more economical with a five speed. At least it won't feel like it wants to fly apart the whole way!

Two of toyota most renown gearboxs will bolt up to this. I'm sure you will have a w40 at the moment? If not you can still change to a w50/w51 steel case or an alloy w55. They all came on r and t series and will certainly fit a 12r. Or even better just get an entire 18r-g engine. 2.0L Twincam, twin sidedraft.

But..... we're talking isuzu here ay....
