Just fitted the A duct to the 1jz and noticed variations in the front bumpers on ma70's. Some have large numberplate section as in the european version and some have small square sections jdm models. Its a pita cutting out the front bumper section. And even more of a pain in the arse cutting away the steel box section. The foam behind the bumper is flame proof so i found out. I used a small angle grinder too cut the plastic bumper away, and a 9inch grinder for the steel bumper. Not a big job, but the metal fillings get everywhere. Heres a pic of the finnished job. Apart from paint. :D
I also made the headlight vent. but not sure if i like it yet.
