vn s1 to s2 cooling conversion

[Pimpn1]

hey guys, im looking at converting my s1 vn motor cooling system to a s2, what needs to be changed, and has this been done before?
im thinking it needs
1. new rad
2. overflow bottle
3. inlet manifold from s2

just not sure what else would be needed.

thanks all suggestions considered

hoses aswell and a different s/steel pipe for the timing cover. thats about it. oh remember if your keeping heads to still use the breather on the rocker covers or u will blow the manifold gasket or even worse the rear main

yeah keeping the heads, so what do i have to do with the hoses? reroute them to the radiator?
cheers

yeah the S2 inlet pcv valve works via a hole in the driverside head on the inlet mating surface it can be drilled easy enough or just adapt the S1 pcv system.
