I'm setting up this thread to allow M96 big bore owners compare modifications to their engines as some seem to fit M97 engine parts, aftermarket exhausts or 997S parts but there are still big gains with a standard engine apart from the bigger bore so it would be interesting to see?
Please post up what you have done and your BHP and torque figures, most people are having their cars mapped on the same rolling road at Chipwizards so there is a good base for comparison.
Currently mine needs to go back for a remap as my first session wasn't a success due to an under delivering fuel pump and a cam actuator not working, but it is booked back in for the 3rd of September and I will update my power figure after that session.
My current mods include a mildly ported head, a standard exhaust manifold but with the inner welds for the flange that meets the engine smoothed flat. I also have the 997 injectors fitted but that is all at the moment. It still pulled 326bhp even with the faults mentioned above.
