it is time for you to do your homework! lots of people on here dont like those kind of questions, valid as they are. the answers are redily available and easy to find

to answer your question DO NOT USE A BIG SINGLE FOR A TOWING RIG!!!!!!!!!!!!!!!!!

ok thanks for that i will do some research to find the best set up thanks for the help

for a towing turbo i would suggest a single S362/68/.80 gated turbo which runs a little under $1500
