93' Radiator Question

[93DriftMachine]

In the near future I plan to put in a 95' and up KA in my 93' 240sx, since they have a little more compression. Will a 95' and up Koyo radiator or any other performance radiator work on my 93' KA motor? Are both S13 and S14 radiators identical? Thanks.

[:: orion ::]

1) All KA24DE motors from a 240SX have the same compression, 9.5:1 Although you may have read in your "Chiltons" or online that the S13 motors are 9.2, they ARE NOT.

2) The motors are externally identical with regards to mounting, radiator inlet/outlet, etc...

The radiator mounting into the chassis is similar for S13 and S14, but the top mounts are closer together on an S13. The hose intlet/outlet and overall size are identical, however. And Koyo DOES NOT Make a KA radfiator for an S14, so if you plan to go that route, it will be S13 specific anyway (they sell it as the KA24/CA18 radiator).
