It can't be easy living across the Pacific ocean and getting these parts. I can see why you wuld be very careful and slow to get anything. Theres a few areas of building a car that some will jump up and shout, this is an area where you just do not skimp. This would be one of them if your getting serious about racing the car. Purchasing a "Econo" C-verter could be OK for a dual purpose machine or a lightly raced car where the racer isn't so serious about chasing the money with victories.
