How to tell a real S

davec · 02-13-2010, 07:15 AM

I purchased an 87na and was told it was an S model. How do I verify that?

Well... for starters it should have a sixteen valve engine in it.

16v Motor and the 944S badge on the rear end are dead giveaways....

How do I tell if it has the 16 valve engine?

Cam cover will be double width (because it covers two cams instead of one).

It will look like this:

Just as I suspected, it is not an s after all. It has the s badge, but not the 16 valve engine.

Gee, I guess that it's easier to stick on an S badge than it is to put in a 16V motor.

Kind of like the VW GTI wannabes, or the boss I used to have that put IROC-Z stickers on his camaro... we used to call it the pseudo-IROC.

I saw the same thing one time at 944Fest. The guy seriously thought it was an S but it had an old 8 valve motor in it.

Either a real S with a replacement 8 valve motor
Stock 944 with a S badge on the back.

This is the S engine.. the airbox is in the front and it says "16ventiler" on it. it should also have a badge on the fender that says "16ventiler". Aside from that the S has bigger brakes, a different transmission and maybe airbags and ABS

Some people think the '88 and '89 944's are S's because their 8v engine is bigger and 20hp more powerful, but the S is a significant 40hp more than normal.. and mine is about 15hp shy of the turbo.

The 2.5 S has the same brakes as the 8-valve. The 3.0 S2 has the same brakes as the 951 (minus the front cooling scoops).

Redline on the dash is higher than the normal 6400 RPM for the 8 valve. IIRC it is around 6800 RPM

My 1990 S2 has the scoops.

I hope you didnt pay 944S money!

You are speaking of a 944 correct? If it was an 87 924, it would definately be an "S"

Paulyy · 02-15-2010, 07:04 AM

post pictures of the back, front, sides & engine, we will happly tell you

Taz's Master · 02-15-2010, 12:32 PM

Eric is correct. An '87 924S would have an 8v engine identical to a 944. What did you buy? A 944S should have a 16v engine. I have read concerns about expensive repairs due to the cam/chain/head design, it is possible that it is an S, but to save money after an expensive failure, a PO swapped in an 8v engine. It is possible a PO installed an S badge on a 944. Both those scenarios are bad form if you are selling the car as a 944S. If it is a 924S, things are probably correct.

A 924S is the old Narrow body and says 924..... Its hard to mistake them for a 944S.... I'm betting we have a 944na badged as a 944S.... or maybe not even badged... Just a lying seller...

iirc, both th e 944S2 and 968 have scoops, they're just shaped differently. I could be confusing the 968CS into the mix also. partno's on PET should tell the story. i.e. that the 944S2 and 968 scoops are the same and the 968CS is a better design...
