However, I too, find it hard to believe that Porsche left 100 "easy" HP out of the factory motor. Detuned by 40 or 50 HP? Sure. Its a common fact that getting rid of restrictive OE emission control equipment can make power. Also makes perfect sense that a good tuner can squeeze a few more HP out of a motor by only assuming 93 (or higher, in the case of race chips) octane fuel, and not being held liable for certifiying the car OBD-II and emission compliant for 100k. Either way, an extra 100HP sounds far too good to be true.

I had FAB Speed exhaust on my 996 TT and the exhaust welds cracked. It was less then 1 year old and I had the local porsche dealer weld it back but the sound was different. Also the dreaded Check engine light!
I also heard that FAB speed exhaust are made in China. If you read other P forums you will see a lot of people complain about the drone noise.


Right now I have GHL exhaust installed on my 00 Boxster S and I am very happy. No problems and the sound is very cool....high wailing..closest to a 355 Ferrari spider with Tubi and GHL is only $1800 and change.

Fabspeed, hmmmmmmmm. Aren't those the same guys who were selling waterfront property in New Orleans last year???

If you want big sound... change the pipes. If you want big HP... add a blower or add displacement. IMHO

I am interested in the same swap. I bought a 2002 996 3.6L with 28k miles, yesterday and I have a 2002 Boxster S to put it in. I want to do the work myself and have most of the equipment to pull the engine but is there a link or website that does a good job of detailing the swap. I have many years of Fab and Auto tech experience. Things I need to know is can I use the Boxster engine harness and ECM? Also what other necessary mods to make it work….

I would drive the car for a bit and if you are happy keep it that way. Since you have an 02 I would keep an eye out for a 3.6 since the 3.4 does not add much more then you can then with a few bolt on mods. The 3.6 X51 or 3.8 (x51 or no X51) is what you should keep an eye out for and just plan to do it if you find one. Myself I have to do the new DME and harness on my 2000 to get a 3.6 in but to me it is worth it, it is all about what you want. I personally wanted more power and did not like any other car I looked at including the C6 Z06. My Boxster is paid off and for me it makes sense but to each their own.

On a 2002 you still need the newer Motronic 7.8 DME to run the VarioCam Plus in the 3.6 as the 02 has 7.2. This is easier than swapping in a 7.8 DME into a 5.2 (97-99) car.

Yes you can use the harness you just need the wiring diagram to make it work. Good luck with the conversion. Will you be doing any mods to the motor while it is out (i.e. X51 head work or cams)? I most defiantly would do a lightweight fly wheel and stay away from the intermediate shaft bolt. My porsche mech says that over tightening is the main cause for failure.

Well that’s good news, the car the engine came out of the harness was already sold along with processor. So the harness was going to run $1K new. If this swap needs a 7.8 DME are you sure the harness will work with small mods. That was my background before, engine driveability and electronics.

Can anyone point me to the info needed to modify the harness and to by a DME?

I would also like to do some internal engine mods like the X51 since its already out.
