I can find all of the gearing options for US sold vehicles with F23 and see that 3.84 is the tallest. Are gear sets interchangeable from other vehicles sold outside US/Canada that are any taller?
Thanks Will! Much better, do you know the rest of the gear ratios? I see this RPO FY1 now searching but just states final drive. Also can I just run the metric 60 degree bellhousing on this transmission?

No, the cobalt 3.63/3.72 FDs only came with a ecotec housing. You will have to purchase a 60deg F23 and swap bellhousings or swap the guts... You can get F23 rebuild and shim selector tools on ebay for great prices....
That’s what I was thinking. So get an F23 bell housing or complete out of a 2000-2002 Cavalier/Sunfire and use this bell housing on the Ecotec version F23 or put gear set from Ecotec in non Ecotec case. Is there an advantage doing one way over the other?

The ecotec case is a bit harder to fabricate mounts due to the location of the mounting bosses on the cobalt trans case with the cavalier being more easily adaptable with mounts made by thelin.. then again swapping the guts is a measure more involved over swapping just the bellhousing. If you swap the guts do try to obtain the shaft holder tray(sp?) that holds all the shafts together when you remove the casing. you can purchase a DVD or search youtube for a step by step guide to disassembling and reassembling the F23.
See JustinBart's thread on installing a 3.63 bellhousing swap F23 onto his turbo 3800
I have enough respect for the power holding ability of the F23 I have one in storage in case I can't get the F40 to hold behind my LF3/LF4 swap as Justin ran ~780hp through his with a quaife and OEM axles....granted no version of the F23 bolts up to any HFV6, mender has adapted it to an LFX with a quad 4 bellhousing and custom trans to block brackets.

It's actually the other way around with regard to bellhousings and mounts. Thelin's mounts are designed for the Ecotec transmissions. Thelin's rear mount looks like it will be ok with the 2.2 transmission, but the "metric" bellhousing lacks the bosses that the forward mount bolts to on the Ecotec housing.
Also, the Ecotec bellhousing is 3/8" deeper than the metric bellhousing, and the accompanying input shaft is 3/8" longer. Justin Bart's thread shows that he had to modify the longer Ecotec input shaft to clear the 3800 crank pilot when used with the metric bellhousing.

All the F23's have the same shifted gears EXCEPT the Saturn Vue transmissions, which have a shorter 5th (as well as 4.40 FD).

It sounds like fabricating a proper front mount might be difficult if swapping bell housings. Also is appears either way the input shaft will need to be turned down as well. So swapping all internals then just getting mounts from WCF for the F23 should be it for mounting the F23. Then cables/brackets/shifter parts all appear to be available.
For mounting and getting taller gears best to swap the internals as you can buy mounts for the early F23 and a sbc vs trying to mount the Ecotec version.

FieroGuru has added the 3.05:1 final drive gear to an F40 transmission, i believe its available in Opels and sabbs in europe. Would doing the F40 6 speed be a viable option for you?
Not to hijack this thread but, since you are all here.... This is a long shot but.... Does anyone have the F23 metric bell housing gathering dust, & willing to part with it? Salvage yards seem reluctant to split the case & sell only the bell housing. They seem to think people are willing to pay to have someone to swap a used tranny into a twenty year old car. At $100/hour labor cost? I don't think so. Even so, where does the old tranny go? It's guts are of questionable use. But I sure could use it's bell housing. LOL It's not that I wouldn't mind stumbling over a spare tranny I'll probably never have to use. It's the shipping cost of a whole tranny vs just a bell housing that is driving me nuts. I'm in southern Oregon. txt me @ 541-941-6545 if you have anything. Thanx everyone, JD

I have one, but it's not perfect, I'm in Washington, near Seattle.
