Porsche Enthusiasts Club Forum

Hi everybody
I have just joined the club and i am hoping someone can help i have a 1980 924 with a Carra GT body kit, i also have a 1983 944 body is rotten but engine gearbox are good,i would like to my 944 2.5 litre engine into my 924.Has anyone out there done the same any advice would be gratefully recived.
here,s hoping

Hi Hecter

Don't know of anyone who has fitted a 44 engine into a 24.
But it will be major work, assuming that the engine cross member fit.
you will need to change everything mechanical, all the brakes, suspension, gearbox, drive tube, wiring loom, dash, fuel tank.

Personally I don't think that its worth the work required, its a project that could take all year

Welcome to the forums. I've moved your post to a more relevant section.

24s had the 2.5 in so cant see why it would be hard to do , just read up on what mounts etc are different . changing a loom isnt hard

I'd deffo want it on early 944 running gear, as I suspect would an engineer/insurance co. The engine/torque/tube would have to be swapped for the 944 as well. The loom & dash should be OK, but the it maybe easier to just swap the engine loom in to the bay with DME connection etc. With an early 944 to rob for the bits & enough space it shouldn't be too bad, but everything is relative

Its not hard, just very involved.

The only parts of the 24 you would use are the shell and trim.

I am not certain, but think that the inner wings are different.
IIRC the fuel tank is different, come to think of it the boot floor is

Remember that 44s have a ECU under the carpet, 24s don't (except the S) have one
If the ECU is fitted in the same place as per the 44 you will need to change the carpet.

Inner wings are not different from the 924-944-968 only the outer structure changes. They changed tanks a few times, together with gearbox mountings, but IIRC the early 944 mount is the same as the 924.
ECU could go somewhere else in a conversion. TBH with a donor car you have a big pool of bits to swap over!
I'd have a word with EMC &/or Jon Mitchell because I'm pretty sure both have done this.

But yup it's still a huge amount of work.

What about the mounts for the PAS res and radiator, is the front panel different?

Good point. Not sure, the reason I know the core is the same is I had the conversation with Ray Northway when I was having S2 suspension fitted to it.

As the 924S uses a 2.5l version of the 944 motor and similarly the running gear I would have thought it relatively simple if not involved to do.

Your right the 924S did have the same running gear.
But IIRC they higher the boot floor to accommodate the later gearbox.
Also when they produced the S did they increase the strength of any of the panels (are the inner wings reinforced)
to allow for the extra weight and stress of the 2.5?

It will make an interesting project, but one to spend a lot of time investigating.

924 has a cable clutch, not hydrol so that needs changing, would you need to weld in the 44 bulkhead mount for the master cylinder ?

The internal core is deffo the same, so no greater strength. As for the raised boot floor I thought that was only the >85 1/2 cars.
Clutch could be an interesting point!

The crossmember could be a problem,the 924 has a steel crossmember.I don't think it's mounted the same as the 944's aluminium crossmember.Along with the crossmember also comes into question the steering rack and control arms because they are all conected.The 944 engine has the mounts bolted to the crossmember and the 924 has the engine mounts on the body so you cant just leave the 924 crossmember,you have to change it.
I'm just guessing about the mounting sistem,it could be the same but it's a slim chance.
Should be an interesting project,good luck.
