Ok, Im new to the forum and fairly new to porsches. I currently own an 02 996 non turbo and love it, however, I've always wanted a turbo. Well today my dream (or maybe nightmare) came true. Today I purchased an 02 996 TT with a bad motor through an auction. I thought it would be "fun" to re-build this motor and maybe do some mods at the same time but dont know where to start. I dont know the extent of the damage to the motor but I do know that it has a 2" hole in the right side of the engine case. Should I be afraid? I am very mechanically inclined but I have never taken on the task of an engine re-build. Im looking for guidance regarding materials (books or manuals) on re-builds. Am I taking on more than I can chew being that Im not formally trained or is this something I can do provided I am good at following directions and manuals? Does anyone have any idea where I may buy a rebuilt or exchange turbo motor and what that might cost? Maybe that might be more my level? All replies are appreciated in advance. Thanks!

 

Well, the special tools required to rebuild a 996TT engine cost about $4,000 alone. Still want to rebuild it?

I don't know anyone who is not a porsche mechanic that has successfully rebuilt a 996TT engine.

There are very few people in the US who can rebuild a 996TT engine. Here is a writeup we did awhile back as to what you are facing.

I would highly recommend just finding a used turbo engine to put in. If you can swap engines yourself, that will be a big accomplishment. That alone is about a 17 hour job, and probably will not be possible without a lift and a large hydraulic table. (I've never tried it on stands, but I don't think it would be possible.

 

most shops will send the motor to qualified rebuilders (porsche)...no need for fear, it's only money

 

Check these people out.

Anybody out there ever use them?

 

A hole in the case would indicate you're going to need a new case, at a minimum. My advice would be find a used engine you can put in the car, and take what can be salvaged off the engine with the hole in it.

A hole in the crankcase, indcates some significant damage on the rotating parts to break a hole throughthe case.
The advice you have had to source another secod hand unit is the right approach.
With the luxury of time you can then dismantle the damaged unit and seewhat you can salvageand sell to recoup the layout on the "new" engine.
I used to do quite a lot of Aston V8 rebulds and I would buy blown engines for bits to rebuild others. Quite profitable. seeling bits like cranks etc earned a nice drink from time to time.
Anyway good luck,lots of patience and you will get there.

Hello everybody from Italy, this is my first post here so I would just like to greet you all fellow Porsche enthusiasts and especially congratulate the Administrator for the link to the awesome page about the rebuilding of a 996TT. Being a 996TT owner myself I was simply amazed by the sheer complexity of the unit, though, after 25 years of driving Porsches and writing abouth them, I would have to be quite prepared to this.....

Thank you again,

Stefano
