911T US CIS, 911/91 Engine (6133001-6136092) - 1944 build.

They switch from mechanical to CIS fuel injection in Jan 73

Hello,I was looking up some fuel pressure specs. in the little Tech.specs.book and I noticed that the C.I.S. cars started at chassis no.911 310 1501...and my eng.no.is nothing like the ones you quote.Michael. [I'm trying to get it to run after an 18 year rest]

Maybe it got an engine swap at some point.

What is you engine type and serial #?

911/51*6124238*.Michael.

84mm bore x70.4 mm stroke

Not a direct fit to your chassis number but your car was completed in Feb 73 so it could be a Porsche thing :D:):D A later chassis with earlier engine.

I've heard that from a few people now. It has C.I.S with steel inlet tubes,swirl pot tank,001 WUR,metal roller fuel pump above l/h rear suspension etc...it has a clear sticker with black writing on the l/h side window[behind driver] DR Porsche.....911....Co2...emissions....etc. and apart from some factory/dealer options is standard.Michael.

As JJ says, but it is a 1972 engine, so definitely not the original.

I am new to forum. Did post a question earlier regarding the spec for a 911(WPOCB2967MS461717) 1991/964 I believe. The engine serial is 62MO8867, I am
pretty sure this is not the original engine, can anyone shed some light on this engine.
Thx

Ken,

The engine type M64/01(62M00001-on) was fitted to a numbers of the 911 cars in 1991.

It does not list WPOCB2967. Its usually a letter in that position.

Are you sure it a "7"? Then again it could be a "check sum" number which would not matter.

The M in the VIN 10th position is definitely for a 1991 model.

MS460001-2207 would be US Cabrio chassis.

thx much. the VIN# definitely indicates a 1991 cabriolet but I am not sure about the engine.

If your car is a Cab, that engine fall in that type/serial fitted.

Why do you think it is not?

You could spend $125 and get a COA that would confirm the match but with Porsch book keeping its always a hit and miss.

Hey guys- Update on calling Porsche and verbally getting any info from them. It's apparently not happening anymore. Have to order a COA to get anything.

I have an 84 M491 Turbo look with a built 3.8 so all that was important to me was a build date. They weren't willing to even entertain a conversation about it.

In the off-chance someone might have info on the car, the VIN is WP0AB0917ES122277

(misleading info removed)...

You have serial 2277 out of 2282, so one of the last one.

If your "3.8" references is 3rd of August 1984, that was a Friday so IIRCC it was part of the E program as they would switch to the F program on Monday the 6th of August 1984.

Good luck

Thanks. Great information.

My 3.8 reference was referring to a 3.8L. As in 993 motor swap. When do you think the later Turbo looks would have been made?

oops... Short memory! Actually, the 9th character is a Checksum Digit that can be 0 to 9 plus X and Z.

Have fun calculating it: https://en.wikibooks.org/wiki/Vehicle_Identification_Numbers_(VIN_codes)/Check_digit
