compounds are precision 62 and 71mm turbos. i currently am running the setup with 190s for a street/DD setup and they are awesome. truck is smooth as silk with plenty of power on tap. If you wanted they could easily handle more fuel i just wanted to keep it reliable and it has worked perfect. the turbos are still currently on my truck with zero issues. as soon as someone comes to me seriously interested i will pull the truck in the shop and take them out. i will send everything needed to mount the turbos including the remote oil cooler setup. id like $5000 plus core parts and shipping for the setup. located in ft worth, Texas. thanks for looking!
