Ive modded basically lost cost motors, a force 28, dynamite mach 28, stuff like that and they scream. the thing I've noticed is that instead of a smooth linear powerband, the modded motors tend to be more peaky, the power comes on very strong very fast, other than that, porting is fun... I have an LRP in my truck, but so far havent touched it. that thing has so much power, I dont know if I want any more out of it...
