thank god this thread came up when i needed, thanks for all the info guys.
So here is conclusion.
i have to change
1. Throttle body to 5th gen (or change both IM and TB)
2. Timing belt assembly including the oil pump housing.
3. Wire Harness for engine.
I do have number of goodies from my engine build.
I have question though....
what is downside if i just used OBD1 ECU.
What do i have to do in order to run OBD1.
We dont have emission nor safetly insepection in florida so i dont have to worry too much on it.
and 1 more question which header do i need to buy in order to bolt onto my exhaust system, because i believe SH header is different length than the base one...
thank you

If you can get away with not being OBD-II compliant thats probably an easier route to take, there would be no need to port over the OBD-II specific parts. You can keep the JDM distributor, ECU, injectors, oil pump etc...
As for the header/exhaust you dont need to change it when going from a SH to base since the differences are to accomodate the ATTS unit which you'll no longer have. My car is currently running a JDM H22A and the SH header/exhaust, the only fitment issue is the header mounting to the rear of the motor since they mount differently between the SH and the base models.
As a side note to this thread I'm currently taking pictures of everything OBD-II specific since they're all off my old motor now. Once I have all this swapped over correctly I'll also include pictures of the JDM pieces for comparison. Hopefully it'll help people identify why certain changes are necessary.
