Question swaping a 924 engine for a 924s

Has anyone done this ? Any problems ?

Plus

1> How does one tell the difference between a 150 bhp ~ 9.7:1 compession ratio and the 160 bhp ~ 10.6:1 compression ratio by the engine serial number?

2> If the swap is not like for like does this impact the working of the ECU?

3> Can an auto designated engine directly replace a manual designated engine ~ ie bell housing differences?

cheers

A

I think this has been covered a few times, maybe do a search for the details. But the big things would be: swap cross-members, the 2.0 mounts to the body and the 2.5 mounts to the cross-member. All the injection plumbing and wiring would need to be swapped, the 2.0 is cis and the 2.5 is motronic. Something would have to be done in the clutch/driveshaft area to make up for the difference in shaft size. Etc..etc..etc..

Adrian, I know nothing about the 'nuts & bolts' side of things, but I can answer your question about identfying the 150/160bhp versions (well my Morgan book can!)

1986 & 1987 150bhp - engine number starts 43G or 43H respectively

1988 160bhp - engine number starts 46J

Good luck!

Swaping a 924S mortor into a 924 is possible, but why do it. The amount of fabrication required would make it just as easy to install a much larger engine.

You would need

Motor mounts
Wiring harness
DME
Drive train
Fuel injection

With the prices of 924S models at the moment, why would you even think about it?

By the way, the front frame rails of of the 924 and 924S are completely different.

It can be done but it is a lot of work. As noted above the cross members are different and mount differently. So you would need to do a lot of fabrication to mount the 924S cross member and thus the engine. I know the 924S/944 motors can be had for about $700 complete but you also need the complete drive train. The 924S/944 motor will not bolt to the 924 2.0 drive shaft (torque tube). The diameter of the 2.0L 924 is smaller.

So it would be a better option to just find a 924S.

An Adrian sandwich.

Hmm. Right hand drive. Must be difficult to find RHD 944's.
