Q&A

Ok ok i am insulting most of the Cup drivers here but i have a dilemma.
Would love to buy a 997 Cup but are terrified of the potential sequential gearbox rebuild costs. Has anybody tried to bring back the 996 Cup manual into a 997 Cup and if so .......... How difficult is it to get it working properly

Thanks

wouldnt be that difficult. Change shifter, cables and gear box. you could keep the clutch and releaser . Change the Adl config

get the pmna auto blipper. be thoughtful of shift points, and you'll probably get 35, 40 hours.
plus frankly, and this is my own take based on my reviews and costs laid out...a 996 rebuild is probably starting to eclipse a simple 997 rebuild. we jsut rebuilt a 997 box for 8,9 grand. the 997 boxes are now prevalent. yes, more fragile, but the 996 stuff is become more rarified.

My wrench recently made converted his 07' cup to a 04' cup 6 speed. He said it was pretty easy. Write him a note if you'd like: Dan@thespeedgallery.com. He's in Hawaii until mid week.....

Should be a no brainer. The external dimensions are the same, axles the same. Just need to change the shifter and cables.

Didn't surfbum do something similar? His car turned out very well.

Thank guys. Great input to contemplate further.

I'm not so sure it's a good idea. I have recently bought an 09 cup and I'm facing the sequential learning curve and fully expect the darn thing to blow up the minute I touch it...I'll admit to being intimidated but on the other hand how hard can it be??? I think learning the brakes will be the bigger issue..BUT I sure do understand the hesitation, the sequential's reputation is not good at all.
I have been racing a 2007 GT3 converted to all cup car specs with the exception of retaining the manual gearbox. The car has easily $100k+ of modifications and is a joy to drive...faster than most if not all 6 cups and mid pack with the 7's. The big problem with the car is that it is virtually valueless because it is so much of a mutt. I'm selling it for the same price as a slightly modded street GT3 of the same year.
I'd think twice about spending a ton of cash changing a 7 cup into a mutt as you'll never get it out. The same amount of money is better spent on maintaining the sequential and keeping the car relatively unmolested. From what I've seen unmolested cups in good shape sell for the same or more as cars with some pretty high buck modifications. Modifying is fun and I really enjoy improving the car, but economically it's a disaster every time. I think you'd be better off buying a 6 cup and although they are a few seconds off the 7's pace, they are a blast to drive.

The car is his signature is a 6-speed manual... thing is sick!

Now that there is aftermarket support for the sequential gearbox and options to buy service parts that don't carry a Porsche pricetag rebuilding a 997 Cup and rebuilding a 996 Cup gearbox are pretty comparible in costs.

Just out of curiosity what is the average cost of rebuild for a 997 gear box?

I don't mean to be tongue and cheek about it, but that's kind of like asking what time does the sun set? Sets at a different time June 19th than is does Dec 5th. What I am getting at is that no two refreshes are identical. I've seen gearbox with 25 hours on them that needed half a dozen parts. I've seen boxes with 10 hours on them that needed darn near everything.

As a general rule, figure mid to upper 4 figures if it mostly needs dogs and claws and up into low 5 figures if it needs a few gears(3rd gets timed out soonest and 2nd tends to get the dog teeth bashed the most, which are not replaceable on that particular gear). And well into 5 figures when you wear out the ring and pinion and/or the mainshaft/1st gear. That's if you send it to an independent who is not using PMNA parts. If you send it to PMNA or BMC&G expect to pay 30-40% more than that.

leigh2...what price are you selling your "mutt"
