guessing it's the CMS billet shifter thingy at bottom right? the boxster tranny in 944 is a guy a porsche hybrids forum I belive? not sure though, only seen the 3 pics, don't know if it's functional or not.
CMS has all sorts of goodies, they could probably make both shafts, adapter, shifter etc, and sell you the GT2 tranny.

I think only reason floor is cut up, is easy access, but hey, I'll do the same, plasmacut & reweld should work, loosing rear wheel well would probably be needed.

as for extra weight, the weight is in the rear of the car, where we need it, yes most of it is behind the wheels, so that's not good, but hey, if I can drive like an idiot, not blowing up the tranny.. yes please!

Do you know the differences in weight between some of the trannys?
Yup +1 on CMS.

I lifted the G86 5 speed boxster tranny and it wasn't all that much heavier at all, it has alu, where the 016R has steel iirc.

Keep up the good work Anders. How does the gearing compare to the 951 box? Rogue had a good post on upgraded CV's and axles from the The Driveshaft Shop.

gearing is good stock, a 996 GT2 will hit like 330-340-350 max in 6th I think?, but also custom gearing is available, for all 6 gears! so.. gearing is what you want it! around. ideally I would gear it to reach 300kmh aprox at 7000rpm input.

I belive lot of the aftermarkt trannies are geared shorter when rebuilt, so should not be a problem at all.

I spent the day at the track with the new RS6 audi, and also a lot in our 997TT and E60 m5.. mm hard day at work rather tired of turning right though.

I just weighed a 996TT tranny, it came in at approximately 175lbs, and a 944 tranny I have out of a car came in at about 120ish. The 944 tranny is approximately 26.5" long, whereas the 996TT is 32 inches long, so some modifications would have to be made to the rear tire well Sawzall. I'll haul up a TT maybe this weekend and see how closely it will bolt up. You would definitely need to fab up some sort of mounting on top, or in the rear to support the weight. Not sure if you could make something work with the existing transaxle crossmember or not.

Oh and adding the shifter assembly would be absolute butter. No problems there, simple cable shifting mechanism.

one of the guys at our garage used to work at a bodyshop, and also a mechanic, and now does fabricating.. he also likes money, and can't speak American, so I order parts for him, and help him out a lot.. I think I got everything covered.

that's only aprox 25KG more, and I will loose some weight from wheel-well removal, but also add some for trannymounts, probably ending around.. 25 total more. that's 25KG well spent, in the rear of the car, and very low.

his car is fitted with an connectors, misc hoses etc for over $6000USD from summit, he had previously bought stuff locally, which is 6-8 times more expensive! gotto love someone running an connectors to their radiator, calipers etc.. on a volvo 240!

like I said, plasmacutter to entire rear floor, and wheelwell.

thanks for the work you do porschedoc I asked around here for a 996 tranny to "test" with, and they would sell me one only, at an outragous price.

for gearing etc, I got this from a buddy

While you are spending money, you might want to install a sequential shift like this

anders44

I looked it up hans, 4350 euros.. auchi, thats almost as much as the complete tranny

if you implement igncut it would be good, but without there really is no use. I looked at their mechanical version at only 3350euros.. still auch a few friends of mine has the oakley design sequential kit, pretty nice, but they haven't got shiftcut.. so still pretty useless.

for that kinda money you are better off buying a 30.000USD full sequantial GT2 box, without the "fake" stuff around it. think holinger? or whoever it was, makes one.

but... if the billet shifter turns out to be like... very expensive.. one might get VERY tempted

HansB

I know the guys (Jurgen Albrts and friends) that promote this. They use it with ignition cut, and they claim it saves them 1-2 gearbox rebuilts per year. Each rebuilt is 5-10k EUR. So from this perspective it is cheap.

The Porsche Super Cup guys (3 years ago, when seq boxes and ignition cut was not allowed at the time.) did clutchless upshifts, just revving into the rev limiter. Saved them 1 sec per lap, at the cost of multiple rebuilds.

anders44

guessing the system has a builtin delay after you push it? until the solenoid pulls gear? an also an external signal to send to engine ECU?

I am "crazy" enough to do it really, we will talk about it, when everything else on the car is dialed in

eniac

Why spend all that money on a trans then have to add a costly add-on for sequential-like shifter? The cost of all that seems to be getting quite close to buying a full sequentional race box box from the start such as a Hewland http://www.hewland.com/svga/gearbox_range_current.htm or even less expensive Mendeola's http://mendeolatransaxles.com/ .

anders44

the ones that handle the power/torque are more expensive eniac. say 15-20k for a mendola that can handle it, vs 6-10k for a G96 GT2 unit.
