I like the look of this engine. The intake manifold looks great and may need a wide toothbrush to carve it from, like I did with the intake box on mine. All the pieces look doable from bits and pieces.
You might note, the 944 engine was a new design based on half of the 928 V8. The 924 was based on an Audi truck engine, heavily breathed on by Porsche. I notice the 924 distributor looks like a typical American distributor and is at the rear of the engine. The 944 distributor (and the ones in the 944 kits) have a flat round one at the front of the engine.
It looks like they moved the battery from right rear of engine bay, where the fluid/water bottles are. Lots of modifications from stock 924.
They are pretty similar in shape so the 944 engine should look good, especially with all the pieces added.
