i installed a boondocker turbo kit on an m8 this year. the turbo in that kit is a garret but i would recommend the entire boondocker kit. that thing really comes alive and so far no problems at all. its a pump gas turbo so its a little lower boost but a little safer. plenty of power. there are a few small differances for the m7 kit than the m8 but they are basically the same kit. a friend of mine installed the cuttler turbo kit on his m8. it is a garret turbo and a boondocker control box but the set up is different. his exhaust exits the stock port which eliminates tunnel driling that you have to do on the boondocker kit. cuttler will instal it for you as well. anyways thats just my two cents.
