What is your horsepower goal? And Why do you figure $1000+ on for Lexus AFM, injectors, FPR system? I found a Lexus AFM with electronics for 30, Evo 560cc injectors for 50, that is almost half the battle for less than 100 bucks? Just look around and you will find what you need affordable if you look and have patience.. I've read this forum for about 3 weeks straight now and I've seen people post that the 7M internals can survive upwards of 500+ HP and I don't know how true it is but I've seen one or two posts of someone running over 1000HP with stock internals. I would start at the fuel portion first because proper fuel delivery is one of the things that prevents your internals from becoming airborne...
