Nah already looked there... not much help...
After doing a little research I've found out that the truck motor has a milder cam in it along with a bunch of other little details. The engine stamp or engine code is d21 I'm not sure if this means it says that on the block or not...
The good...
I am going to be able to use it in my 240 but I will need to swap oil pans, the oil pickup, oil filter mount, engine mount brackets, and the dipstick hole is in the wrong place, so I'll have to drill a new one and plug the old... Lucky for me I have all those parts laying around already...
The bad...
The s13 sohc came with a crank gurdle which is a far better made setup than the truck sohc was made with. The block's are pretty different and you have to use the truck crank in the truck block. The car crank won't work b/c the crank's are different lengths. The truck block is a little longer than the s13's and the the flywheel will grind on the back of the block if you use the car crank.
The truck block is also lacking the block to transmission skirt that the japanese motor has. Also the starter is different, I'll need to use the truck starter and harness pigtail... The sohc truck block's were made in Mexico and the s13 block's were machined in japan. So they have different engine stamps on them as well.
The truck block has a rear sump oil pump and the 240 has a front sump oil pump which is why you have to change the oil pan and oil sump location.
The pistons in the 90-97 d21 ka24e yeild a 8.6:1 compression ratio
Most of the ka24e pistons in the truck versions of the ka24de are top coated with graphite similar to ka24de
They use a lot of the same parts tho which is good...
What this all means is I can use the motor that this guy has but I need to customize it a little for it to work in my car.... All important sensor's are the same tho and I just need something to get me by till i finish up my dohc ka-t that I've been working on for ever now lol...
I'll let you guy's know if I go through with this or if I abandon ship! More research is still needed....
Maybe someone else can tell me what's up with that egr lookin tube on the picture I posted earlier.... I'm still left wondering
I've never seen it like that before
