For a 2WD 911s can you run larger diameter tires without looking cartoonish?
The turbo box, though expensive has slightly taller gearing, too.
I have and Email into gbox, requesting a price quote on re-gear to 3.0:1 and rebuild. I maybe not going with LS3 heads to save money to spend on the transaxle??

I'd imagine the re-gear would be at least $5k, i've read online that parts alone are in the $3k range.....too rich for me
But please do share the pricing when you find out!

So I contacted Weddle direct, beings they produce most transaxle gears. They told me that Albins make or has the Porsche gears made somewhere else. They can get them from Albins for $3,100.00. So $3,800.00 for Gbox to rebuild and re-gear the G96/00, $2,400 for a LSD and $3,100 for the parts, $9,300 is to much money to put into this transaxle. For $9,250, I could pick up a Mendeola SDR5 and have it built and geared to my liking and it will handle 600-700 HP and comes with a LSD. Looks like the next project will be getting the SDR5. And the SDR5 bolts direct to an LS and uses GM clutch components.

$9250?! Holy ****..... for a trans. I almost bought a dirt cheap 996 from a buddy in hawaii with an IMS failure to do an LS swap. Glad i didnt. Ill just stick to my redneck cars.

The stock G96/00 transaxle can be used, it's just a little low geared for some people. The R&P is 3.44:1, 1st 3.82, 2nd 2.20, 3rd 1.52, 4th 1.22, 5th 1.02 & 6th 0.84. The adapter plate, flywheel and clutch is $2800 from Kennedy Engineering.

Did a quick calc assuming 255-40-18 tires, and I get 2600RPM @ 70MPH. Doesn't seem unreasonable at all. My 914/LS1 with Audi 01e transaxle sees 2200RPM @ 70MPH and it feels like it's just putting along.
Yeah, anything Porsche is expensive by comparison.

I just did a quick measurement and my 18" are 24" tall. I've got a set of 19" that are 25 1/2 tall. I'll have to do some experimenting.

its not terrible, its pretty good gearing for having fun you just dont get that famous corvette idle rpm @ 80mph!

Too bad i like cruising 80-85 All the meets and events around houston are spread out so there is a lot of hwy to open up on. Its great gearing around town though and i'm sure really nice and tight for road courses and parking cone tracks!! It really reminds me of driving an s2000, real tight gearing. Just wish i had a 7th gear that dropped me to 1500 @ 80! lol... i think thats what the modern porsche's have.

One day you'll be able to swap in the latest getrag transaxle with 7 gear. But not many generations of those left.... as Porsche is so slanted towards PDK.
As long as you have 2WD, running larger diameter wheels in the back is fine. If 4WD, I think you'd need to swap to larger diameter fronts, too. Changing the circumference ratio on 4WD is a no no.

Would larger wheels in back confuse the abs? I put C6 wheels on my camaro once and braking was a nightmare.
So I have not got much done this week, way to busy at work. Just got the transaxle pulled out and started thinking about the way I will plumb the cooling system. Renegade provided the following diagram, for running the electric water pump.
I did a little playing around on Bluebeam and came up with the following diagram based on the flow of a LS water pump shown in the next photo.
I would like some feed back, telling me if I am on the right path or still need to do some more planning. Thanks in advance!!!
Try to keep the cold and hot lines on the same side all the way back, crossing them is harder then it looks, not much room to cross.
On my 99 the factory pipes/hoses criss cross (as in the above pic), which what was the confusion when i commented on your hose routing when you were mounting your electric pump.
Just know that the top port on the waterpump goes to the top ports of the radiators and the bottom port of the waterpump receives the cooled fluid from the bottom ports of the radiator.
On my 99, looking from the rear at the engine bay, the right side (pass side) coolant pipe goes to the tops of the radiator (hot). And the driver side pipe goes to the bottom ports of the radiators (cold).

The line cross under the car from the factory.

That is how I have it routed, your 99 should be the same as my 01.

You've got the heater port logic reversed on the water pump. The hot side is the small diameter tube (5/8"), and the cold side is the larger diameter tube (3/4").
