THE KNOWLEDGE

The two new engine mountings shown here were supplied by Porsche Centre Reading, the go-to source for most, if not all, of the independent specialists here in the UK. Part numbers are 964 375 049 01 and 964 375 050 01. (Universally, items for the left side of any Porsche are denoted by an odd number within the group of digits shown in bold type, and those for the right-hand side by an even number.) They cost £267.46 and £249.97, respectively. (All prices shown here exclude VAT.) The equivalent 993 parts – 993 375 049 09 for both left and right – cost just £229.54 per pair. (They appear not to be handed, and so for that reason there may be some minor issues in fitting them to a 964, although we believe the difference to be simply the absence of the small locating tab.)

There are various alternatives from Porsche itself – not least for the higher-performance RS models, which by virtue of their stiffness will not necessarily be suitable for long-term road use; and Targa and Cabrio mounts are different from those for the coupé – so the safest policy is simply to order against the car’s VIN. Reckon on about an hour’s professional labour to have them fitted (£85 plus VAT at BS Motorsport: 01296 658422; bsmotorsport.co.uk), or do it yourself in no more than about 90 minutes. Tightening torque for the two M8 screws per mount is 25Nm, and for the M12 nut securing it to the engine bearer 85Nm.
