I wouldnt worry about what oil you use because yours isnt a white car with one of the good motors in it anyways
DISCLAIMER: I read this on the internet

 

Are you referring to the US Carrera Cups from Andial?

Those were not European RS models.
Last I knew, there were never any RS models imported into the US for street use.

I would defer to Bob for the definitive answer:

Ah yes the RS America is probably what I saw. Course it could be a regular 964 with tail and decals..... but I like it either way. Definately says RS on the side and has a younger guy driving it.

 

US Cups were an RS with a few add ons, like electric windows and the big seats. Otherwise they had the same blueprinted engine, DME, Seam welded chasis, big brakes, G50/10 tranny, shifter, lightweight carpet, no rear seats, RS suspension, aluminum hood, soundproofing delete, radio delete, AC delete, ect.. Definetely an RS, and the only street legal RS to ever be factory imported to the US. Until the GT3 RS that is.

 

Sorry, I just consider the Euro RS (all variants) to be different from the US Carrera Cups, just like I consider the US Carrera Cups to be different from Euro Carrera Cups.

 

Not really much if any differences between N-GT M-003, Euro Carrera 2 Cup, US/Euro RS/US Andial Carrera Cup. Drive train and DME all Identical (andial never opened the DME), Some Minor Suspension differences... RS vs Cup springs and struts. These may of may not be on a US Andial Cup + minor Dot Bits. Early Euro Cup's Have M64-01/G50-03 LTD 40/40 drive train & 473 Bosch DME Are these significantly different Not IMO.

 

Yup, its an RSA. I wish it was a euro RS. You probably caught me coming back from Summit Point last weekend.

 

Cool, do you live in St. Marys? I see it all the time in St. Marys county, but I'm never in the 951 at the time Does it have side damage too?
