gearing up for speed and mileage
#41

ok - it's official - no gears out there that work - period



i'm now down to 2 options:



option 1: cut apart OEM gear, use the splines from that one and weld them into the new Audi gear. not cheap. may not work. expensive if it doesn't, as i would have to then replace the OEM gears with new ones, and R&R the box again.



option 2: make custom gears. 2 month lead time. expensive in one-off.



more than likely i will go option 2, and do this down the road in the winter. i want my car back, and i do not want to lose the summer and fall messing with this.



that's what i get for relying on internet info from people who don't know what the heck they are talking about. i should have taken the hint when they kept calling the box a G46 when it's a G44, and definitely not an 01E



but hey - now i know a heck of a lot more about our box

Yeah seems your right, 1-4 is same, 5th is .882, 6th is .711. What do you mean its not an 01e? My understanding is that its a G50 diff, and 01e box. Have you tried JHM motorsports? http://jhmotorsports.com/shop/catalog/01..._60_102_26



I was quoted about 1k/gear for custom one offs from CMS.

nope. not quite. a lot of the parts are from the 01E, but some are not (the gears for example)



the gears at jhm are the 01E diesel gears. WAY too tall for the 968, even with the supercharger. it would put me right back where i started, with not enough torque to pass without downshifting.



they changed the 5th gear in the turbo for the same reason i want the .73 6th. gear spacing is a big issue. .71 is too far away from .912 (stock 5th). so, they had to also change 5th to drop in between 4th and 6th and keep decent spacing.



this has been a real pain.

Flash would a turbo gearbox work for you as well ?

Or are you looking for a different setup all together .



I am asking because the company where i got my rebuilt box from , is a specialist i these things , i could give them a call to see if they have what your looking for .

if you mean a 951 box, no, that would not work. i don't want to lose the 6 speed, nor do i want to change anything in the lower gears.



i'm really just looking to do what they would have done, if they had a bit more torque, which is give 6th some more legs, lower the rps a little bit, quite things down a little bit, but not give up the character of the car.



if you meant a 968 turbo box, sure, that would probably work, though i'm still not sure about the ring and pinion ratio. but i seriously doubt there is one of those around anyway



it's no big deal for me to have a 6th made. it just means i have to wait until they are done being made. oh well.

I'll give them a call see if they have anything , my guess is if it's there they have it or they know where it is'.

It is no big deal , at least you know in case you change your mind .

Id be interested in just purchasing a 968 TS trans. Obviously flash has dibs, but it would work perfect for my needs. I didnt think I could find one, so havent been looking. That, and Im not quite at that stage yet. its on the horizon though. Just not highest on the list at this point.

it will be interesting to see what happens from that. i'm all but positive there is nothing, as i checked through "normal" channels already, but worth a look for sure.

Manfred his answer .



Hello

The modification is not possible as all off the internals are different .

I have a NOS Gearbox for a 968 turbo S .

Price 12000 Euro's + 19% + VAT



Best regards



My question to him was if there where any parts and if it was possible to convert the standard gearbox to a turbo S .



The price is actually not that bad , since Porsche Germany itself asks about 12743.- Euro's for the standard 6speed





Looks like a custom fit job to get it to work on the standard box .

well....



converting a standard box to a turbo s is possible, and it has been done. it's almost as expensive as buying the whole box though, because there are enough of the parts that are different.



no worries. i'll just get a custom gear going and be done with it.



thanks for looking into it though.

No thanks , but i guess i was at the right adres if they have these kind of things laying around .



And when he says it can't be done , he could be right , there is a big change the conversion is not a 100% replica , but with some differences to make it al work .



Let's see what you end up with . <img src="/forum/images/smilies/968/ninja.gif" class="smilie" alt="" />

So, roughly $20,000 for the transmission with VAT and shipping,... I'll take two!

Dayum, 20k? You still pay VAT even if you dont live in the EU? Seems like I could replicate one with mine as a core for much less, but I may still be interested. Vliegwielolaf1234, can you get details on what getting it stateside would entail? I wasnt planning on more than 10k on the transaxle, but for OEM NOS, I may be tempted to go over that.

Put in an order for a Turbo S final drive ( 31:9 ) this morning which will arrive this wednesday, hope to have my spare tranny rebuild by the end of next week and clash it under the car that weekend. With 400 Nm @ 2750 rpm ( with more to come ) I think it will be Ok in 5th and 6th.



Not cheap, 3K Euro but it will bring me a brand new box and a top speed of over 3K hectometer <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" />

i didn't want to do that due to what i thought it would do in the lower gears. i wanted more launch, and i would be giving up a lot of that with a taller final ratio. still not sure what i will end up doing. for the moment, i just put it back together.

I think that's a misunderstanding ; if I have longer gears I'll have less gear changes to make to reach desired speed, assuming I have enough power to coop with the longer gears ....



If I want to do a 0 to 100 Kmh sprint I would be faster if I don't have to gear up at all .....

the lower the ratio the better the launch. 3.778 will launch better than a 3.44. the tire spin/lugging thing is the problem. taller gears will only exacerbate the problem. it will be even harder to find the "magic spot" between tire spin and lugging the engine.



i barely hit 2nd now in a 0-60 dash. that part isn't really the problem. hook up is the problem, and i have a gummy 285 back there. i could really use a lower gear for better hook up, but then i would lose all top end.



with the SC i am able to launch a full 500rpm lower than NA, which helps a LOT, and the lower you can launch the better, but it still isn't enough. in a perfect world, you could dump the clutch and not have it lug or spin the tires, and just take off.



no, these cars are not designed to be 0-60 cars. that doesn't mean that we all don't want them to have a good launch. nobody likes getting their butt kicked off the line by a hyundai.
