RUF Engine Number Location

[mcompo]

Hi, have re-joined PH after a few years away.

Does anyone have any idea where a 911 (993) RUF engine number is likely to be stamped. Have had a fair search for it but not yet found anything. Anyone with specific info out there as to whether it simply replaced the original number, or is additional and/or in a different location?

Thanks

Engine serial numbers on early 911's are to the right of the fan housing as you look at it on the crankcase; the engine code is stamped on the top and is under the cooling shroud (requiring removal of alternator or shroud to see it). On later cars the complete number is stamped into the underside of the crankcase. Not sure if RUF stamp additional numbers if they modify the engines - happy to be educated; but I've worked on a few and not noted any added numbers.

The factory 993 wiring loom recall still applies to the RUF models - worth checking the VIN to see if it has had it (if needed) and if it needs it it'll be easier to spot the engine number mid-work.

Thanks Pope thanks for the info - wiring info useful too. I thought RUF would have a special engine number series perhaps, seeing as they have their own chassis numbers. Will take a look & post back on here once I've found something.
Thanks again

Sorry to jump in, where are the RUF Chassis numbers located ? On a 964 RUF it appears to be in the factory position. In this case on the bracket where the engine kill switch is ?
