Can anyone give me an engine wiring diagram for 2003 3.6 996 engine?

Thanks

Is there a specific area or question?

The engine schematics are on two very large pages.

Of course you can always buy the schematics for your model year at the Porsche Tech website for about $110 US.

I'm doing an engine swap into a 2.5 Boxster, and could use a wiring diagram to speed up sorting whats where on the engine. I need advice to try and sort out what if anything the original ecu can run, and what other functions such as Variable Valve Lift and eGas I need to sort additional controllers or Ecus for.

As its for a semi-track car, it doesnt need the total mapped refinment of the original. eGas will probably be swapped for a cable throttle assembly. Rpm mapped controllers may well suffice for intake valve & Variocam Plus functions.

Any advice or knowledge would be helpful. I believe my ecu is a Motronic 5.2.2, has anyone managed to remap these?

Thanks

Thanks Loren for the links. I had previously seen what was said said in those useful threads. I guess I just want to take the harder option & get the 3.6 working rather than opting for a stroker conversion or less complicated 3.4 upgrade.

3.6 is generally viewed this way as a more reliable unit than the 3.4, gives more power, and a stroker conversion would still need remapping. larger valves, diff cam etc

Seeing as I have an unemployed 2003 3.6ltr sat in my garage at home, I'm keen to get started on getting it prepped to go into the car.

I'll take some snaps of any sensors that I'm unsure of, post them here and hopefully someone can identify them.

Thanks

Right, I've had a chance to take a look at the 3.6 engine and have some queries / questions regarding sensor functions.

In the pics can anyone confirm the role of the sensors numbered in the pics, my "guesses" at the moment are:

1. (to top right of number 1 box) : Valve timing adjustment

2. (to top left of number 2 box) : Valve lift adjustment

3. (to left of box) Oil Pressure

4. (to left of box) ????

5. (to top left of box) Knock Sensor

Can anyone help on this?

Thanks

You are correct on all your assignments, #4 is oil level/temp sender
