The kit is made by aoshima but I think it's the same as AMT's f&f supra. Aoshima did this before with the original AMT f&f supra kit. Same tooling, different box. Easy way to tell if it is the same as the AMT kit is to check if it is 1/24 or 1/25. All of aoshima's kits are 1/24 except the supras that they borrowed from AMT. Also not many of aoshima's own kits come with complete engines.
The model is looking great so far! Could we see a pic of the wheels that came with the kit?
