Radiator

[FLEXXX]

i was wondering
1)does the s13 radiator fit the s12
2)will it make any difference in performance or ruin the engines ruinning if you use a smaller rad
3)does the AC system interfere with the IC fitting and plumbing
just wondering coz when i start this side of the modding i want to make sure i get all the right bits and also install the setup as it would have come from the factory neat and tidy
