1996 KA24DE into 1990 240sx questions

[Philthese93]

Hello zilvia. I know this question has been beat to death. I have googled. I will be following the nicoclub "ka24e to ka24de step by step swap". Things i currently have; s14 resevrior tank, s13 dohc cluster, and i will be purchasing s14 PS lines. Now my question is this..

Do i have to buy a 1996 radiator?

I currently have the upper and lower engine harness and an s14 auto ecu. Will that suffice with my swap?

Radiators are all the same for ka's
