Oh man, now I have to go measure the ears on a 914 trans and see if it fits between the IRS inner pivots...
(Edit-They don't... but that's a feature.
outside span 18",bolt CL ~16.5", but it is just right for the front trans mounts sit on TOP of the T3 pivots, axle CL/mount offset ~correct too)
Add cable shifter, flip diff, done.
(many, many steps glossed over to make it sound like an easy weekend project using only a sawzall and vice grips
Heres the gearing of the 923 trans, mash up, sources courtesy of the 912 registry and rennlist
The 923 trans is basically a 915
923/05 11:35 17:34 23:29 26:25 29:21(.7241) 6:29 (4.8333) 5060001- '76 model year
914: (late/most) A F N V ZD final
901/11 or /12 5 11:34 18:34 23:29 27:25 31:22 (.7096) 7:31 (4.428:1)
I have no idea why I cannot get the formatting right, it's readable ...
Trying to find same info for T1 trans combos... The 914 trans is at least taller geared than the 923.
I've been looking at just going with mucho sound deadening, but I don't think I'll make it >30MPG with these heads etc w/o dropping the RPM.
If I keep it a 1.8. I'll probably stick some 1.8S or even 1.7 heads on it and fix the deck while I'm in there.
(It will probably end up with a 2013 tho)
I got to actually work "on" the Pile for a few hours yesterday, went through the motions of installing the 996TT rear brakes on a spare trailing arm, with early 911 parking brakes.
Looks like the ID of the parking brake drums was consistent over the decades, and if I want wider shoes the 996 hardware LOOKS like it fits the 911 backing plates.
This is on topic as those 911 parking brake setups can be made to fit any T1/T3 rear arm as well, so I'm looking for another set of backing plates, rotors, and more $75/set monoblock LS430 calipers.
