i think alot of workshops have probs getting parts from japan,
especially turbo kits, certified by lta because of the hassle they
have to go through. apparently, in addition to getting
certification from the aftermarket part maker that a particular
part is suitable for use on a particular car, they actually have to
fit the exact part on the exact vehicle before sending the car to
be tested by the japan equivalent of the lta in singapore. somemore
no guarantee will pass that side after all the work. nobody would
have the resources to do all that for each individual
vehicle/engine combination unless ur influence is greater than
those of barney the dinosaur on kids.
