sex drugs and swirl pot`s

[idiot goes sideways]

the question is simple,
how to install a swirl pot in a ca18det s13?

i know how it works on cars like an Cosworth with an "expansion tank" in their cooling system.

YES the s13 has also an "expansion tank", but its not like the cosworth its more like a passive one on the s13.

SORRY FOR THAT VERY BAD TRANSLATING BUT ITS HARD FOR ME TO TRANSLATE TECHNICAL WORDS, PLEASE BEAR IT,
SO LETS CONTINUE OUR LITTLE FUNNY CONVERSATION WITH OUR LITTLE "ENGLISH SPEAKING WONDERBOY" (me)

besides i found two types of swirl pots,

one with just two piping fittings and a breather, like bailey`s

and the second one with a radiator cap, like greddy

i think i need the second one but how should I install it and how would it work????

Good driver's have the flys on the side-windows and Swirl Pots under their hood. My driving sucks, the Swirl Pot won't help but I want it!
