actually they have decent turbos ppl have made decent reviews for there turbos. Im not looking to make crazy huge hp like rock u world and break records. If it works it works if it dont it dont its only $200 i cant justify to myself to pay $2000 for a kit just doesnt comprehend that kinda stuff but dnt worry i will let everyone know how it works out. What about ppl on HMT.com make kits for like 250 with spare parts and they run for over two years
