That x51 intake manifold will not fit on a 3.2 block and probably not a 2.7 either... different bolt pattern...... also that TB part number may or may not be correct for your setup... the 986 and 996 car's TB have a different bolt pattern than the 987 and 997 cars as well.....also porsche has identical part numbers for different size and pattern TB's..... been through all of that with my swap!!!!!!!
