I just put 225/45/16 with Z32 rims on my N/A.. Does anyone know if this is going to mess with my speedo?--Also if it does F-up my Speedo how do I make it work properly?

It shouldn't mess it up too badly. The 16's that came on the Z31 Turbo's had 50 series tires on them (I believe, but I don't have the turbo wheels on right now to check). You N/A 15's should have had a 60 series tire, and you went up an inch in wheel size, so you should have lost 10 in the series.

-5% error.

i.e. your speedometer reads 100mph, you're actually going 95mph.

i wouldnt worry about a %5 error because once you get up that fast your speedo starts to get off a littel anyway
