Turbo S engine case 930/66S
Hi guys, I bought this case 7+ years ago for a 964T project that I no longer have. I was going to build it but at this point I am not sure I want I want to do with such a rare case. What can you experts tell me about it? Can anyone tell me how many 87 Turbo S cars were made? Also I have been looking at S cars and it seems like the sequence of the serial numbers on these S cases do not restart every year. I found an mid eighties car with serial 2XX and the slight later that was a 4xx serial number and this 87 is a 6XX number. Not sure though since there is very little info like that that I can find. This is the only S case ive seen so trying to figure out exactly what I have has been a bit difficult.

A lot of looks but no comments...lol. Am I correct that this is pretty much the same case as the m30/69? I do realize the M30/69 case has a 964 casting number but the case itself is the same, no? They only switched to full cylinder support on the M64/50 when they switched to the std 964 case correct?
Thanks for any help.

Looks just like a late model 911/930 up until 1989, nothing to do with a 964 case as far as I can see.

The M30/69 doesnt use the 964 fully supported cylinders like the M64/50 case. The M64/50 case is a 964 case where the M30/64 is a 930 case with 964 casting numbers. Here is a pic of a m30/64 case. It doesnt have all the webbing around the cylinders like a m64/50 or M64/01.

Case through bolts are recessed in above picture, just like 964, therefore different from 911/930 cases.

Fact is, if you put the "S" case next to any other '87 930 case, the only difference you will find is the "S" machined/stamped into the case, lol.

Absolutely, just like a 930 shell is the same as a 930SE except the VIN stamping but the price would be a bit different.
