Sorry, force of habit, in chats with others I always refer to the 2.5 8V as 'Lux' to differentiate from the 2.5 16V 'S'

Theres no need to apologise: Im sorry if I sounded as though I was telling you off. Im almost always rushing so everythings 'straight out of the gun'...

I have included a couple of pics including one of the Air Flow Meter I just bought. (couldnt resist a glamour pic too).

Its booked into general mechanics tomorrow for partial strip to understand whats been done. Can anyone identify the head type from photo?

Thanks for all your help and support...

That is most definatley a 16 valve head

I feel cheated. When you said glamour shot I was looking for ladies

I would sirguesst its a 944 S 190bhp engine, the air box is also S modle. 3ltr 16v s2 head looks the same , but the air box is under the badge pannel, could be just that it wouldn't fit s2 air box under a n/a badge pannle. And there for is a 3ltr s2 with a 2.5 air box. But from the pic it looks like a S air flow meter as well. I'm sure theRe differnt. Not sure if the manfolds are differnt between the S and S2. I have 944S so I could check anything your unsure of againsted mine., I don't think 2.7 8v block would work with 16v head.

The 2.7l block and the 3.0l S2 block is one in the same thing. That looks like a 1987 944S to me.

The car was registered on the 1st of January 1987, so was built in 1986. It is registered as a 944 2.5 still, so the previous owner did not update the DVLA. Perhaps the VIN number could be run through PET to check if it was built as an "S" as it does not say this on the DVLA database, only if the current owner would like to supply someone his VIN number. I'm a novice @ PET so don't know if you can put in the reg' number and get the results. If it can be established what the car started out as, then what you have will let you know how much alterations have taken place?

Just checked and DVLA would record if a car was registered as an "S" on the database, so this car DID NOT start out as an "S". This makes it very interesting indeed!

Well, that looks very much like my 'S' engine bay, although the AFM looks a lot cleaner

Looking at the exterior pic, it looks like it has the 'ventiler' script on the moulding on the front wing, although a bit hard to make out for sure.
If it didnt start out life as an 'S' someone has gone to some trouble to make it look like one.

edit: just done a free check at mycarcheck.com, mine is registered as a 944 S Coupe, entering the reg above lists a 944 Coupe, the mystery deepens !

How much power is the car regusted 2 have? 190bhp would mean that's it's and 1986 S. The S also has the 1st and 2nd gears from 220 turbo. Other then that? Not 2 sure what else there is 2 tell them apart, other the 16ventler script on the side molding by the indactour. Which it has!

So iv a 3ltr and 2.7ltr block is the same and the 16v heads are the same then a 2.5 head would also fit a 2.7ltr block. ?

Not sure what you mean here Terry but yes the 2.7 & the 3 litre blocks are effectively the same but a 2.5 head won't fit a 2.7 block.

Yes that is a 944S AFM and inlet manifold, cam cover and therefore head is 16 valve, also 16 ventiler scripts on wings, does the tacho show the red line at 6800 rpm (S) or 6200 rpm (lux), maybe if car was originally a lux then ECU is still original, not sure if this would allow engine to run or not, but if only revs to 3500 rpm and this is where the kick comes in on the S engine so a possibility

I think you're right Lindsay. Someone has put all the "S" gear on and not changed the ECU. I wonder if it can be re-mapped or does it need replaced. If it has been bored out to 2.7 ltr then it becomes even more interesting. They obviously didn't know what they were doing and threw in the towel.

Hi Guys,

You have all got me worried now, the car is badged a 944s, has the "ventlier" body strips and the rev counter red lines at 6800 ! Cant believe anyone would bother so much to disguise a standard 944 to look like a 944s. Anyway its due back from the Mechanics Friday. The AFM IS brand new and is for a 944s - because I bought it last week in a failed attempt to solve the fuel problem.

EMC - the mechanic says the only difference between a 2.5 and 30l cylinder head is an extra coolant hole or two (pretty important then).

More later.

I wouldn't be overly worried. The 2.5 8V and the 'S' are pretty much the same apart from the engine (and I believe the clutch) they share most mechanical parts (brakes/suspension etc) and interior wise are identical. As mentioned earlier it may be that the ECU has not been changed as the 8V/S/S2/turbo all use different ones. If opportunity arises try to get hold of the part number on the ECU to confirm which one it is. The ECU is located behind a wooden (yes wooden !) plate located in the passenger footwell. Pull back the carpet from just below the glovebox and you will see the plate held in place by 4 screws, behind that there should be a metal frame to which the ECU will be attached, it may be possible to read the part number without taking the ECU out, but it is a pretty straight forward job to detach the ECU from the wiring loom if you do need remove it. There is a guide on Clarks Garage in the Garage Shop Manual section, listed under DME - control unit removal and installation.

The part number for the 'S' is 0261 200 080
The 8V could be 0261 200 076 or 0261 200 086 or 0261 200 057 depending on the year

Anythin else could be S2 or turbo ( dont have the numbers to hand)
