Is it worth the time, effort and money to install the Garrett GTP 38R on to the older powerstroke motors? I have checked on kits to fit the turbo to my application and they are around $850 not to mention the turbo. My objective is to increase the power on my truck after having added a chip, downpipe, and soon to install baby swamps. If anyone has made this modification, I would appreciate your opinion. Thank you!
