I have a the M178 engine with the same turbos, uprated cooling and dry sump as the GTR. Is there anyone on here with tuning ideas, especially anyone that has a GTC or GTR they have modified?
Currently I have a set of 200 cell downpipes with the GPF delete ready for installation. The cat 6 versions are about £1600 which I thought was reasonable considering the build quality and heat protection. There is a cheaper one at £1350 but it is cat 5 and not guaranteed to pass the emissions test.
