Just joined and have my p10 di engine out after 600k and wanted to straight swap a de and keep my di intake to save swapping looms. The di head has much smaller ports diameter wise and intake mount is dead vertical. The de ports come off head at about a 30 degree angle and mounting points are different. So there is a big difference between a de and di head. Also my di flywheel is close to a third thinner than the de???
