Nissan 200SX Club - South Africa

Can anybody tell me the differences between the T25 turbo's on the CA18DET and SR20DET and if possible of all Nissan's that came out with with the T25 turbo.
I'm essentially looking for the info on A/R Ratio's and wheel Sizes.
From what i can gather:
SR20DET
Turbine A/R .64
Comp A/R .80

CA18DET
Turbine A/R .64
Comp A/R .48

Any other info that you guys can help me out with?

there quite a few threads on this, use the search function

I've been looking for the specs using the search function and i cant find zip.
Most of the topics are like this.....

Any other info or differences that anybody could inform me about?
