If you are referring to the R154, they aren't completely bullet proof until a couple of mods are made. The 7m stock can make quite a few ponies, and if you aren't a retard you can make plenty of power without spending the money to swap a 2j. I have seen some nice 7m setups, you should take a look at Chris from Zen Motor's 7m powered supra. I am sorry you live in world filled with such tunnel vision.
On topic, I have a soft spot for MKIII supras, and hope you have fun with your project.
