Coolant Line Question
 

Is using a -6AN line (3/8") too big for feeding coolant to the turbo? Currently running 5/16" hose, but changing everything to steel braided lines. However, the fitting I am going to use to connect the lines to the the hard pipes only come in -6AN and not -4AN.

Are you asking if it's too big from a flow standpoint? No such thing when it comes to coolant lines.

Obviously it's not going to fit onto the existing water nipples on the block, but it sounds like you've got a plan to deal with that.

Ok, good to know! Just didn't know if too big a line makes it harder for the coolant to get to the turbo effectively.

Obviously. And yes, I do have a plan. I'll be posting up the finished result as soon as I get done with the project in case anyone else might be interested.
