I'm currently running my stock 90 si radiator and its cooling fine. You should check your thermostat and water pump. Also the del sol dohc vtec will not fit, its too tall . I tried the one way you can fit it is if you modify the crossmember which i thought wasn't worth it . On the other hand i have been told that you can use a 93 teg twin core radiator . Hope this helps, lata
