I know that this is going to sound dumb to you, but I am not as well informed about these car as most of you. Here is the question. Can I take any regular, non-turbo, or S, 944 engine equipment, i.e. computer chip, or anything else, and put it onto my 1987 924S?

Thanks. kcaK85 <img src="confused.gif" border="0">

Your 924S has a 944 engine anyway. But, if you wanted to put a 944 Turbo engine (or the 944S engine) into the car... yes you could do it, but I honestly think if you want to go the 944 turbo engine route, it would be better (and possibly no more expensive) to actually get a 944 Turbo. At least then you get a complete upgrade: suspension, etc.

As for a 944S engine, I doubt if it would be worth the trouble for the relatively little gain. More top end yes, but less low end.

If you really have the rebuilding itch for a 924S, probably the best project would be to rebuild the engine to full 944 euro spec (by raising the compression). This should give you 163 hp without any extra mods... and that's a 15 hp gain.

A chip for 924S will be the same as for the (same year) 944. The feedback is mixed on how good they are for the non-turbo 944/924S series. Basically, for what I've heard is that if you get the right chip, you may see a small improvement in power... but not much. One thing a chip can do for these cars is slightly improve the 0-60 acceleration. Not by giving any extra power, but by raising the rev limit slightly, so that you don't redline the car in 2nd gear at about 56 mph (or whatever). So you only need one shift to hit 60.

Also, if you hunt around, there are 2.8 liter stroker kits for these engines. A 924S with a higher compression stroked 2.8 liter engine would (I'm guessing) give you in the order of about 180 (or more, maybe 190) "real" hp, with the torque to match. Such a 924S would be reasonably fast, and probably quite "streetable" (ie: not all top end).

(By the way, I've never done any of this stuff... I'm just passing info on I've learned from these forums. I'm sure many of the pros here can tell you way more)

an s2 engine in a 924S would have good low end and top end. a 968 engine would have even more, but then you have to change more parts (bell housing, torque tube).

Perhaps supercharging your existing engine would be a viable option. There's a few good aftermarket companies producing kits for the 924S/944NA.

I believe the original poster is talking about engine components i.e. does any 944 engine part(non-S) fit/work in the 924S and my intial response is that any 944 engine component is a direct swap for the 924S part for part except sheet metal obviously.

Thanks to everyone who answered, Mich, you are the winner though. Thats all I needed to know.Nut I do appreciate everybody's input.

Canuck924S

what are the aftermarket companies that are produce the supercharger kits for the 924S NA engines and what are some info about the different kits

Thanks

The 1987 version of the 924S had the exact same engine as the 944. The factory sponsored race team had 944 cars and were getting thier asses kicked by 924S cars. They lowered the compression for the 1988 and later 924S cars to save face at the track. They should have switched to the 924S instead. Just put a turbo on the original engine and you can beat a 944 and maybe challenge a 928.

What are you talking about? They who? For MY 1988 Porsche raised the CR on the 924S to match that of the same model year 944. The compression ratio went up from 9.7:1 used in the 1986 and 1987 924S to 10.2:1 for 1988. Then, because of poor sales numbers Porsche axed the 924S.

Sorry if I got my Information wrong. I only know what I read. I'm no expert but one thing I am sure you are wrong about. They didn't make a 1986 924S. Look it up.

Actually they did tough guy. It was introduced for the 86 model year for the rest of the word, and as a mid model year (1986) offering for the United States as an 87 model. Look it up

Okay, here is what I have - '86 924s 150 h.p. 86 944 163 hp. For 87 and 88 the 924 hp was raised to 160 and the 944 was actually lowered to 160 (equal) Most sources seem to agree that US cars had 150 hp.

The 1988 924S has a different motor than the 86/87 924S. 1988 used the 10.2:1 engine, code M44/09 while the 1986/87 models used the 9.7:1 engine, code M44/07. This is what facilitiated the additional (roughly) 10 bhp on the 1988 model.
The 1988 model also uses a different chip than the 1986/87 model years. The 86/87 model years used DME part number 944 618 121 04. The 88 model year used DME part number 944 618 121 05.

Oops, double post.

I thought a trick the racers used to make the 924S faster was to swap out the gear box...I think Porsche wanted the 924S 'detuned'...
