ca18det reliable help

Hello Everyone,:dw: Really need your help, I have a 200sx S13 that has had a SR20 conversion but my loom has burnt out! I am meant to be drifting on sunday so need to source one quickly! So if anyone has one to sell or knows where i can get one please let me know and i will love you forever...

Im picking up a bog standard 200sx and dont want to mod it, just want to get it as reliable as is possible with a ca18, and just use it. Mileage is high on it, 170k isk. Timing belt was done not long ago. What steps can I take to prevent the inevitable death happening? Certain oils, oil...
