renizer sorry for awakening F40 threads back from the dead but....

it seems to me the F40 has a removeable bellhousing. it would seem then, that you could change this bellhousing at say, an ecotec F40, to mate to the B2x5 engine.

further more, i found this in EPC, saying that the bellhousing is the same for all the TiD diesel engines?? Z19 being the 1.9 TiD as well as the D223L (Y22DTR in opel speak)... is that a mistake in there?

that would be the part no in WIS, but better check the casting letters on the bell house...it should be: GM 12787 363 0822680

sounds more than good to me...as I said looks like that milling machine's going to see some work in the near future for sure...thank you....

GenuineSaab F40 Common 4cyl Gearing on 225s as the other charts.


On the Big 245s I run. Nice and tall.


with 24.5" slicks




Now compare to the std 9-3 5speed on the 225s. Just a taller 6th is all. You will have to match the tabular data rather than the charts.

Making the hardware there work right is harder but in the end going faster with less says something about the hardware package. Going 6 speed because it's "cool" is not the right way.. I don't like wasting money where it wont be needed.
Totally agreed and my project is do everything myself as low cost as possible tbh but want to do it so that i'll get more than a day outa the box...lol...I see people cryo gears and all that but what's the best mods really....do you list it all on your site...lol...think not...well not to handle what your racer's puttin out anyway...

Words of a wiseman!
The 6 speeds mod/upgrade is for now project in data/info gathering. I will not spend a $ more before I see the output chart compares for F25 and F40, both with the same wheels and at the same revs.
If any1 got this kind of info, please post it.
The straight-cut Quaife...well, that's another story and is specially for racing. Not for drag, though....
So yeah, kinda makes sense not to jump for the aquisition!

:P :P
On a more serious line, 6 speeds really improve the car`s performances (especially over 350HP) and the gearbox is more resistent than the F25.
I won`t seek/search any other reason. Seems it is one of the "grown-up boys" mod, not stickers & decals kids
In a more personal tone: me wants!
Had a look at your saab and gotta say it's a got a lotta seriously nice bolt on bits ....but with brakes like that you know ya want a bigger monster turbo in it...ya do really dont ya...!...lol...

I wish you well in your endeavor to build a one of a kind Saab.
That's why I mentioned it makes a Quaife seem more feasable and it's difficult having the luxury of Nick's expertise when I'm in Northern Ireland even though he does seem to give a lot of his experience free of charge here and elsewhere...maybe I'll be using that upright milling machine sooner than I thought...maybe one day I'll get a tutorial pm'd to me...HINT HINT.....lol...

As much as I like you guys here and at SC, my big regret is that I don`t talk swedish! They have loads and tons of infos regarding SAABs and SAAB tuning. Whatever mod/tune you want...name it and they already DID IT!

9-3 ss nav on 9-3 old gen? DONE!
6 speeds F40 on 9-3 old gen? DONE!

and so on....
Actually, those guys drive +500 HP SAABs regulary!
By chance, a Romanian guy (very freindly and helpfull) is living in Sweeden and he gives me some technical details. AND I MEAN TECHNICAL DETAILS!

I will keep you posted on this F40 story on my car (is it a Vigg?), in the thread "my project"

Tweek's Turbos One was on craigslist locally, but I doubt it was the deisel version.
