i have a 94' b18b1 and i want to put in my 94' eg, i was wondering if there is anything special like mounts, axels, wiring...

 

I've had done this swap to my ride a couple of years ago.

If you use the b18b engine wiring harness then it would be plug and play at the shock tower.

You can use your civic engine wiring harness but you might have to convert it 4 wire o2 sensor depending on your model civic. If not then you might extend some wires. But that you be it.

Axles you can use the 94 and up intermediate shaft with 94 and up axles. You can use 90-93 intermediate shaft with 90-93 axles.

The mounts i cant remember off the top of my head. Somebody probably shine in with a pic

 

here you go, you can thank katman for this pic
