Is the swap made easier if you're using a standalone EMS? Or would the process still be the same. Shame since there are a wealth of Tip cars floating around, but the 6MTs are slim pickings.

 

The largest issue lies in all the wiring changes that need to be done. There is no simple way to do it, so much has to be removed, and so many wires have to be changed.

 

Interesting threat. I am looking at this project for my 997 tip to manual. Same restrictions here. It is not about the price difference, I live in a place where there are NO manual cars around and importing is simply prohibited. So no alternative other than driving a tip or going through the hassle.
Actually after studying the wire diagrams the changes to the electronics should be minimal. Most of the wires run from the Tip Control Unit to all the components (transmission, shifter, steering wheel and instrument cluster). The TCU only connects to the ECU (DME) through a few signals. If the ECU is reprogrammed or changed (watch out for the IPAS codes!) to manual it won't be looking for the TCU anymore and everything should work (clutch pedal signal is the only thing). You could leave all the wires for the Tip in the car and could even convert it back if needed. All mechanical changes are plug & play (of course engine has to come out, transmission and cooling system for the tranny needs to change, drive shafts, tranny mounts, shifter, pedal cluster, hydraulic lines etc). What am I missing on the electronics? I can imagine a change from a manual to a tip is insane as all the TCU and wiring is simply missing and needs to be put in the car. That is nuts and all interior has to come out. But tip to manual should be fairly straight forward. You will just be running an extra wiring harness for the TCU and Tip that is dead. Let me know what I am have missed on the wiring side for a tip to manual swap?

 

For the 996, wiring is apparently not that much an issue - as in the post below. I have no first-hand experience with this sort of conversion, but I am very well versed in auto electrics/electronics. I see no reason why one could not stick with the original wiring harness - for the 996 - as described in the post below. You'd simply have numerous wires/connectors left over and doing nothing. Manufacturers generally do not change the layout of the harness completely, so additional components such as the auto trans just receive a new harness with extra wires. Apparently Nitrorocket changed the harness to a manual transmission harness - which would obviously entail quite a bit of work.

I'd be very careful with this project on a 997, though. The ECU's in the 997 became much more advanced than in the 996. Certain ECU's may need to be "coded" to work with a manual transmission (better said, without an automatic). I'd try to verify that you can have all this done before starting.

 

Stevemfr you are correct. I am not that familiar with the 996 but all the main electronic components on the 997 are programmed with some codes (IPAS) working with the immobilizer. So a swap of the ECU is not possible without reprogamming it. The challenge is to get these IPAS codes from the p-factory or find a helpful mechanic that can get them and do the programming for you. If you simply swap it, the car won't start anymore.

 

Before you even think of doing this, are you an extremely advanced DIY-er? As in a motor re-re in your garage is no big deal and you can pull that off with out thinking about it? If not don't even think of doing something like this. It's not add some pedals, 3 wires and a tranny. Unless you're very advanced you'll never get through this, end up screwing up your car and have to pay something to finish it which will cost more.

Simply put, sell your car and buy a manual it's just not worth it.

 

Hello.
Happy New Year and lets wish for and work towards a better 2021.
I have been considering this conversion for a while. Most threads say dont do it, but now the price difference between the manual and tiptronic has grown to about $20,000 here.
I consider myself and advanced DIYer having restored a couple of P cars, 944s, 928s and 911s in the past. Just a few months ago I repaired all the coolant pipes on my 9996 turbo in my driveway.
My questions for this conversion are:

• Can the clutch, flywheel and gearbox from the NA car be used
• the tiptronic comes with an adapter plate. can the NA transmission be mounted to the adapter plate and have proper clearance for clutch operation
• there is no way the dealer in my country will recode the ECU, who else can do it?

Thanks in advance.

 

By the time youre done you'd have spent a lot of money...

6 to 10k for turbo trans.
1k to 3k for clutch

imo buy a higher mileage 6mt turbo
20k or not by the time youre over and done with you'll have a 6mt turbo without all the headache of conversion.

 

It’s actually not a bad job, It’s easier to go from an auto to a manual then your manual to an auto.

And by the time you saw your automatic you can buy a six speed trans for about the same price. You will need a front diff too. Different gearing.

I did a full manual to auto swap years back.

 

what about if I have 2002 donor 4c with all the part but with terrible body conditions and swap it with 2004 targa? Just switch all the components or I still can meet some problems?

 

Thanks for sharing your experience. Have you also worked on PDK-to-manual conversions? If so, how much more complicated is it compared to Tiptronic?

 

I did buy a higher mileage manual with accident history and many issues. It was hit at the rear right thus the muffler hung about 2 cm lower.
Engine out for complete clutch system replacement, slave and master cylinders, fuel hoses, oil pressure sensor, water pump, coolant pipe pinning and all new hoses, 964 RS engine mounts, 2gear detent, RWD conversion, suspension refresh, GT2 rear wing, OEM wheels, banged up and leaking aftermarket headers swapped for OEM manifolds, upgraded diverter valves etc. the car is entertaining to say the least.
On top it looked good but underneath it was a hot mess. Enough dirt came out of the radiators to fill a flower pot.
That was a couple of years ago.
Now the low mileage tiptronic is just sitting with fuel pump issues.
