Now for the remainder of seat possibilities you must perform a seat pan swap. Don't worry tho it's easy like Sunday morning...#1 thing to keep in mind is the longer it takes the better it looks. Let's get started...
What you need is:
Seats of Choice (Integra,S2k,RSX,EP3)
Needle Nose or hog ring pliers if you have em
Zip Ties
Razor
Socket Set
Patience
Take your needle nose and remove the rings holding the seat cover onto the pan on my Civic seat the backrest frame was held on by little metal rings... on the integra there was a zipper you need to grab witht he needle nose pliers the location of the zipper head is pictured....

Here is the Civic seat with the Skin and cushion removed, here you can see how the Civic seat has the bracket coming out of the cushion..

Get your razor and cut a hole where the seat bracket has to come out (guesstimated it).Also do not remove the rings from the cushion... it creates slack in the fabric if you dont fasten it back down correctly and the foam then holds it in place is fragile...

Comparing the backrest frames and seat pans, very similar...



EP3, RSX, S2K and any others with fixed headrests must use that specific back. After separating cushions from pans unbolt the lower pan from the back and substitute it for your stock one.

After putting the cushion on the the seat pan secure the the skin with zip ties or hog rings where applicable...


Typical flaws..



Notice how the head rest are the same and the Integra slide/lock fits perfect...

Bolted down...


Some ending results...
