Hehe - I believe that by the end of this coming weekend, I'll have the interior and engine bay stripped completely bare, leaving only a body on wheels.

Anyway, yesterday I started taking the engine apart in place since our engine lift is being borrowed and I'm too impatient to wait for him to return it. After taking off the alternator and intake manifold, I noticed that the block has 7 ribs! The head is, of course, a bigport one so I'm a bit confused on what kind of an engine this actually is. The way I see it, there are three alternatives;
[list]
[*]If the entire bottom end is from a zenki AE92, it should have 9.4 CR pistons with 20mm gudgeon pins and a crankshaft with 42mm big ends.
[*]It could also just have the 7-rib block and standard AE86 crankshaft with 40mm big ends and 9.4 CR pistons w/ 18mm gudgeon pins.
[*]Finally, it could be a full kouki AE92 bottom end, using 10.3 CR pistons w/ 20mm gudgeon pins and a crank with 42mm big ends.

Well, I guess I'll see which of those is true once I get the engine pulled off the car.
