springs for my 90q from another model?

[Rebecca Ruston]

I hardly ever post on here, but have fun reading stuff and am curious about something.
I have an '88 90 quattro and I'm wondering if springs from the 4000 or 100 or some other model would fit on it. I'm gonna end up buying springs or maybe even a coilover setup but for now I am wondering if there are springs out there that I might find at a junk yard that would affect the ride at all.
I am not trying to lower the car, actually taller would be nice...
