Stock NA VS Turbo Springs

Stock NA VS Turbo Springs
I have a question, we are putting in new strut cartridges on my 87 NA and wondered if you had the choice of using the stock 87 NA springs or a set of springs from a 85 Turbo car which would you use? I have a Turbo parts car and can get the springs out of it. Just wondering if there's be any difference?? Guess we are looking for a firm sport ride but not planning to buy new springs.
BTW I have a full set of Turbo springs,, actually 2 sets.

All done
Guess I'll answer this myself.
We went ahead and installed the springs from a 86 Turbo on my 87 2+2 NA. Those springs plus new gabril shocks/struts gave us a very firm ride. We kind of like the new ride it's for sure a firm sport ride like what I'm used to in a sports car.
When we stood the Turbo springs up next to the NA there was about 1 inch diff in height , however the Turbo spring was a much stiffer spring. After all was done we did not notice any diff in the height of the car.

Here;s a link some great z31 info.

Notice that all Z31 springs were the same except
<table class="inline"><tbody><tr class="row0"><th class="col0 centeralign" colspan="6">Spring Code / Applied Model </th> </tr> <tr class="row1"> <th class="col0 centeralign"> Spring

Guess I need to add that there were small variations in springs over the yrs and models, only those I listed showed any real difference when looking at the Lbs/in. The Lbs/in is the weight required to compress the spring, the higher the number the firmer the ride will be. All the years and models other than those I listed had the same 136 Lbs/in front and 140 Lbs/in rear with only minor differences in the overall spring size.
