ali nismo

i put a 2JZ fuel pump because the GT-R fuel is not available in bahrain. i did not changed the injector and coilpacks, but i change the spark plug many time. ya i have taken it to mechanics, but no one find the problem!!! the problem is in bahrain there are no skylines much and a few whom work in it and understanding in RB25s. i think the problem started when i remove the wiring and i re-arange it nicely. Do you think when i change the wiring and the coilpack and computer, the problem will solve??
